Three steps for safe use of ANY high-power appliances

Follow the steps below for safe use of ANY high-power appliances:

  1. Inspect outlet connection and contact strength. Insert a standard, two-prong plug (without third, ground connection) into an outlet. Ensure that both prong connections offer equal and strong resistance when inserted. If the two-prong plug does not offer strong resistance or one prong feels easier to insert than the other, this outlet could be unsafe for high-power appliances. Have an electrician inspect and/or replace any such outlet before use.
  2. Inspect outlet and timer plug after each use.
  3. If you are for any other reason unsure about an outlet, have an electrician inspect and/or replace the outlet, as safety is of the highest priority.

Extension cords

Some extension cords are not adequate to carry the load of current drawn by this heating unit without becoming dangerously overheated. If an extension cord must be used, do not use a cord set rated less than 1500 watts or 15 amps, and it must have a minimum size of 16 gauge. Use only an extension cord with the UL seal. Use of an inadequate extension cord may result in overheating of the extension cord or starting a fire.

There are 3 extension cords provided with your ZappBug Room that are designed to work with your thermal unit. These extension cords are, of course, safe for use.

Old electrical wiring and outlets

Each ZappBug thermal unit will draw 12-15 amps of current (1500 Watts) and must be run on circuits rated 15 amps and above only. Some old electrical wiring and outlets may not be capable of sustaining these loads. If you are unsure of the electrical wiring or outlets in your location, contact an electrician before operating ZappBug or any other high-current products. If electrical cord(s) appears deformed or feels hot to the touch, unplug immediately and contact ZappBug customer service. Old or faulty electrical wiring could lead to damage, dangerous fires, and/or injury.

Additional warnings

  • Failure to comply with the warnings presented by this manual may result in severe injury and/or damage to property.
  • Incorrect assembly or improper use may result in hazardous conditions. Only assemble according to instructions in this manual.
  • Do not block air intake or exhaust vents on the heating unit. Obstructions of the intake or exhaust vents can cause the heating unit to overheat.
  • Do not use outdoors or in a wet environment. This product is only designed for indoor use.
  • Do not block exhaust vents. This can cause damage to the heating units.
  • Do not reach into or insert objects into ventilation fan while running. This may result in injury or damage.
  • Do not place flammable objects or aerosols inside the ZappBug Room.
  • Some items may be damaged during heat treatment. Use caution when heat treating fragile items such as antique books, items made of wood, and other treasured belongings.
  • Consult the manufacturer of items in question (such as electronics) for a maximum safe temperature before placing them in the ZappBug Room. Always monitor the temperature to ensure that it never exceeds a safe level.

Choosing a Treatment Location

What should the ambient temperature be?

You will want to choose a room indoors with a temperature of at least 70° Fahrenheit, or about 21° Celsius. Treating in a cooler location will cause your unit to struggle to get up to temperature.

What type of flooring should I treat on?

Carpeted areas work best. If you need to treat on hard floorings such as wood, tile, linoleum, or concrete make sure you have an insulator between the ZappBug Room and the floor. These types of floors absorb the heat from the bottom of the unit causing the unit to struggle to get up to temperature. Insulators such as area rugs, thick blankets, towels, foam pads, or even cardboard will work great.

Finding four independent circuits

The ZappBug Room needs four independent electrical circuits, one for each red thermal unit. Three extension cords are included in your package to help reach a second circuit. Usually, each room is on its own circuit. For example, you could connect one heater to an outlet in a living room and another in a kitchen, bathroom, or nearby room. If you are still having difficulty finding separate circuits, the electrical panel usually has them labeled.

How do I test if my treating location will work?

If you believe you have found the best treatment location available to you, you can test it by setting up the unit and running it empty. The unit should get up to 120° Fahrenheit within 15-20 minutes. If your unit isn’t getting up to 120° in this timeframe, please double check the previous steps to ensure you have it in the ideal location.

Unpacking

How the package arrives

Your ZappBug Room will arrive in two non-descriptive and discrete cardboard boxes. One will have the tent frame, fabric tent, and tent carry bag. The second will have all the accessories.

What’s included

  • Manual
  • Support Blocks (4)
  • Support Net
  • Timers (2)
  • Red Thermal Units (2)
  • Thermometer and Sensor Pack
  • Extension Cord
  • Fabric Shell
  • Packing Sleeve

Connect recirculation fan to room frame

The included recirculation fan mounts to the room frame. Position the recirculation fan in the middle of the frame against the back wall, as shown below. It is normal for the recirculation fan to tilt slightly to one side. Slide the recirculation fan power cord through the small opening on the middle top of the back wall. The recirculation fan may be plugged into the same electrical circuit or outlet as one of the four heating units. The fan inlet should face into the room and the outlet should be directed at the floor.

Unpacking

Connecting the Red Thermal Units

How to place thermal units in sleeves

  • Locate ventilation tube
  • Place base of the thermal unit in the tube first
  • Stretch tube around the heating unit (observe the “Do Not Cover” markings)

Gaps

It is normal for small gaps to appear between the textured side of the Heating Unit and the Ventilation Tube. Bed bugs will not escape through these gaps if the Heating Unit is on. Bed bugs experience thermal shock and are not capable of moving towards the Heating Unit. Always ensure that the Heating Units are on when placing the potentially infested item(s) inside the ZappBug Room.

Tip-Over switch

The Safety Tip-Over Switch is a small black button located on the bottom of the red, square heating unit. When your unit is plugged in, the button should naturally be pressed in. The button must be pressed in for the unit to turn on. Should your unit ever be knocked over, the button would be released, resulting in shutting off power to your unit. This ensures safety in the case of any tip-over accidents. 

If you plug in your heating unit and it does not turn on, please check the safety tip-over switch, to verify that it is indeed pushed in.

Setting Up the Support Configuration

Loading the unit

Airflow is important while treating your items. You want to leave at least two inches between your items and the sides of the ZappBug Room. You also want to make sure your items are not touching the floor of the unit and are placed on top of the support blocks so the hot air may fully flow around the items.

Avoid blocking the heater vents

Please make sure that there are no objects placed directly in front of the heaters. Always make sure to leave at least 6-12 inches of space between where the hot air enters the inside of the unit and where the items are placed.

When items are packed too close to or against the heaters, the heaters become blocked and the hot air is trapped. This can cause the heaters to become deformed or stop working during treatment.

Please note: There is a safety fuse inside each heater that will permanently disable it if the vents are blocked.

Shoes - Use Caution

In some rare cases, shoe glue may soften and shoe soles may separate during heat treatment. To help avoid this, treat your shoes alone, in a single layer in the center of the unit, place the sensor inside one of the shoes, and treat for 20 minutes at 120° Fahrenheit.

Please note: Bed bugs typically die in 5-10 minutes at 120° Fahrenheit. To be safe, we only recommend shorter than an hour when treating sensitive items. They should be treated by themselves or in very small loads that you can monitor closely, so that you are able to guarantee all the items have reached 120°.

Electronics

With more sensitive items such as electronics, we recommend treating alone for 20 minutes at 120° Fahrenheit.

It is rare for electronics that are used to be infested, as the internal temperature of the device usually gets pretty warm. Think about your laptop or your gaming system fan turning on, this is to cool down your electronic device and bed bugs want to avoid the heat.

If you are still concerned about your electronic device you should consult the manufacturer for a maximum safe temperature before placing it in the ZappBug Room. Always monitor the temperature to ensure that temperatures never exceed the indicated safe level.

Please note: Bed bugs typically die in 5-10 minutes at 120° Fahrenheit. To be safe, we only recommend shorter than an hour when treating sensitive items. They should be treated by themselves or in very small loads that you can monitor closely, so that you are able to guarantee all the items have reached 120°.

Books

Arrange the books in towers on the support blocks – eg. for the ZappBug Room you would have four towers of books, one on each support block. This ensures that there is heat surrounding the sides of the books and makes it easier to get up to adequate temperature. Also note that stickers on the books may lose their stickiness and come off.

Clothes

When treating clothes it best to place them in two or three fluffed up piles (think fluffing up a feather pillow). Also, if you need to treat a lot of dense clothing, such as wool sweaters, jackets, and sweatshirts, you should try to break them up into other loads with less dense clothing such as t-shirts and undergarments. The denser the pile, the longer it will take to treat. Think about cooking a turkey in a conventional oven, the larger the turkey, the longer it takes to cook, but if you have two or three chickens in the oven they will cook a lot faster.

Plastic bags

Anything you are waiting to treat should be placed in a plastic bag and sealed until you are able to treat it. Placing items in sealed plastic bags will help avoid reinfestation. It is faster to remove items from the bag and place them in the unit directly, but if you are concerned you can place garbage bags directly in your unit. Just make sure the bags are open and are not blocking the heating vents.

Setting the Wireless Thermometer

Thermometer base station setup

  1. Remove the battery door on the back of the base station, shown in Figure 1 below.
  2. Insert one AA battery. All of the LCD segments will light up for a few seconds to verify all segments are operating properly.
  3. The thermometer base station will instantly display the ambient temperature. The probe temperatures will update on the display within a few minutes after you place batteries in the probe.

Thermometer probe setup

1. Remove the battery door on the back of the thermometer probe by sliding the door down and insert one AA battery.
2. After inserting the battery, the remote sensor LED indicator will light for 4 seconds, and then flash once per 60secs thereafter. Each time it flashes, the sensor is transmitting data.
3. Close battery door. on the thermometer base station. While in search mode, the reception icon  will flash
4. Place the three wireless thermometer probes in the deepest (most insulated) part of your the items begin treated and allow the ZappBug Room to run for 60 minutes or longer after the temperature reaches 120oF in all three locations.
5. If you are not present while the unit is running we advise setting the timers to 8 hours, however, this is generally more time than required for the ZappBug Room to reach 120oF and maintain it for one hour.

Where to place the sensors

Place wireless thermometer probes inside the deepest (most insulated) locations of the items being treated. Examples would be in the center of a pile of clothes or blankets or inside a shoe or purse. The goal of the sensor is to ensure that all the items in the unit reach 120° Fahrenheit.

Distance allowed for monitoring

The maximum thermometer monitor distance for accurate operation is 20 feet without any walls or objects in the way. To keep the best signal stay within 10 feet of the unit.

Changing channels

Press [CH/+] on the back of the thermometer base station to view the different thermometer probe temperatures (see Figure 1).

They will display in the following sequence:

CH1- CH2 – CH3 –

               

Reset

To do a quick reset, remove the battery from both the probe and the base station, wait about 15 seconds for the power to drain, and then re-insert the batteries. Again, first insert batteries into the base station, then follow that with inserting batteries into the probes.

Running your Treatment

Timers

Plug each heating unit into the included timers, then plug the timers into outlets. After plugging in, select the appropriate time setting on the timer by pressing the “on” button to cycle through the time options. We recommend using the 8 hour setting for large loads and the 4 hour setting for small to medium loads.

Always use the included thermometer to confirm that temperatures reach lethal levels.

Waiting the appropriate time

It is impossible to know the temperature at every location in your items so we have developed and tested a foolproof strategy to ensure that your heat treatment is effective.

Bed bugs die at temperatures of 120°F or above, in less than two minutes. However, they begin dying at temperatures above 113°F. Several studies have shown that bed bugs die over a range of temperatures and that the higher the temperature, the less time it takes to kill them. Standard practice for heat treating is to measure the temperature at one, representative location. When the temperature at this location reaches 120°F and is held at 120°F (or above) for one hour, you can be confident that any bed bugs in your belongings are dead.

Bed bug kill times

  • Researchers have found that bed bugs at all life stages die quickly at temperatures at or above 120°F.
  • Bed bugs suffer from thermal shock and cannot escape through the heater duct while the heating unit is on. Make sure to turn the heating unit on before placing potentially infested items inside the ZappBug Room.
  • Bed bug eggs are nearly translucent and incredibly difficult to detect. A best practice is to heat treat all items that may have been in the vicinity of bed bugs even if no bed bugs are found. For pictures of bed bugs and bed bug eggs, please visit https://www.zappbug.com/bed-bug-pictures
  • Bed bugs are unable to climb smooth, nonporous surfaces like those lining the ZappBug Room.
  • Bed Bugs suffer from thermal shock and are immediately unable to move at high temperatures.

Other pest kill times

Sensitive materials

In some cases, you may be treating more sensitive items like shoes, electronics, antique leather, etc. To help avoid damage, treat your items alone or in a single layer in the center of the unit, placing sensors inside the items and treating for 20 minutes at 120° Fahrenheit.

Please note: Bed bugs typically die in 5-10 minutes at 120° Fahrenheit. To be safe, we only recommend shorter than an hour when treating sensitive items. They should be treated by themselves or in very small loads that you can monitor closely, so that you are able to guarantee all the items have reached 120°.

What can I treat?

Anything you feel comfortable leaving in the trunk of your car on a hot summer’s day is what you should feel comfortable treating in your ZappBug Room.

What not to heat treat

Do not treat:

  • Anything with a low melting point: lipsticks, cosmetics, vinyl records, crayons, etc.
  • Anything combustible: hair spray cans, aerosol cans, etc.
  • Anything flammable: matchbooks, lighters, fireworks, ammunition, guns, etc.
  • Remove paintings and photographs from frames. Frames can be treated, but the heat may damage artwork and photographs.
  • NO LIVE ANIMALS.

Anything you feel comfortable leaving in the trunk of your car on a hot summer’s day is what you should feel comfortable treating in your ZappBug Room.

Treating in bags and bins

Anything you are waiting to treat should be placed in a plastic bag or bin and sealed until you are able to treat it. Placing items in a sealed plastic bag or bin will help avoid reinfestation. It is faster to remove items from the bag or bin and place them in the unit directly, but if you are concerned you can place garbage bags or bins directly in your unit. Just make sure the bags and bins are open and are not blocking the heating vent.

Removing hot items

Be cautious removing items after your treatment. Especially metal items that conduct heat well, as they will be very hot to the touch.

Airflow

Think about heat treating your belongings in the same way that you think of drying clothes in the sun. If your belongings are densely packed together, it will take significantly more time for them to reach bed bug killing temperatures. Always use provided ventilation blocks and/or net to ensure maximum air circulation around your belongings.

Cleaning the Room

Vacuuming

Use a vacuum hose to clean out any debris.

Soap and water

If you need to wipe down your unit, use soap and water and wipe it down with a rag. Avoid harsh cleaners

Folding and Storing

How to fold the unit

Reverse steps 1-7 and store the ZappBug Room and Accessories in the two
included carry bags.

Store

Store the folded room, thermometer, timer, support blocks, and net inside the carry bag. Store the heating unit separately.

Troubleshooting Tips

Wood, Tile, and Concrete Floors Absorb Heat and Significantly Increase Treatment Time*

Avoid Overstuffing.  Airflow Around Items is Important*

Thermometer reset

If you’re having issues getting a temperature reading, you may need to do a simple thermometer reset. To reset your thermometer, first, remove all batteries from the device (both from the sensor and the display screen). After all, batteries are removed, first re-insert the display screen batteries. Then, you can reinsert the sensor batteries. This order of battery insertion will reset your thermometer.

Keep in mind, that it can take some time for your unit to fully heat up (sometimes 2-3 hours or more depending on the room, on ambient temperature, and size of treatment load). Also, note that the display screen may lose signal if it is too far away from the unit, or if the unit heats above 140°F. If this happens, simply follow the reset instructions above.

Heater not working

Safety Tip-Over Switch

The Safety Tip-Over Switch is a small black button located on the bottom of the red, square heating unit. When your unit is plugged in, the button should naturally be pressed in. The button must be pressed in for the unit to turn on. Should your unit ever be knocked over, the button would be released, resulting in shutting off power to your unit. This ensures safety in the case of any tip-over accidents.

If you plug in your heating unit and it does not turn on, please check the safety tip-over switch, to verify that it is indeed pushed in.

Difficulty heating

The most common reasons as to why units might struggle to reach 120°F or above are ambient conditions and item arrangement. The ZappBug Room works best in rooms that are at least 70°F or above. Whenever possible, do not run the unit on concrete flooring; if you must, place insulation (such as cardboard or area rugs) between the ZappBug Room and the floor, in order to limit heat loss. Always arrange items as spread out as possible to allow air to flow easily throughout the unit.

Thermometer probe tips

If you aren’t receiving a signal from the thermometer probe, you may need to set the probe channel. To do that, remove the back of each thermometer probe and change each probe’s channel by sliding the button to position 1. All probes need to be on the correct channel in order to monitor treatment accurately.

Optimal circuit management

Make sure each red heating unit is on its own circuit. The recirculation fan, however, can be on the same circuit as one of the heating units.

Hard flooring

Hard flooring, such as cement, wood, linoleum, tile, etc. can absorb heat from the ZappBug unit. This won’t cause damage to the floor but may cause your unit to struggle to get up to kill temperatures (120° Fahrenheit).

Resolve this issue by placing an insulator such as an area rug, cardboard (like the box your unit came in), towels, foam pads, etc. between the flooring and your unit. To test your unit and ensure you have it in the best treatment environment, turn it on while empty. It should take 15-20 minutes to reach 120° Fahrenheit. If it doesn’t reach 120° in 20 minutes, please check out the other troubleshooting tips.

Overstuffing

If your unit is struggling to get up to necessary temperatures, you may be overstuffing it. Think of cooking a turkey, the bigger and thicker the turkey, the longer it will take to cook. This is very similar to “cooking” your clothing. We suggest leaving a few inches of a gap between your items and the unit wall, as well as 6-8 inches of clearance in front of the thermal unit, so air may circulate around your items. If you are treating thicker items like sweaters or blankets, try to mix in less dense items such as t-shirts and thin cotton.
