ThermaCell ProFLEX User manual

Welcome to ThermaCELL®Technology
Dear ThermaCELL Heated Insoles ProFLEX Purchaser:
Thank you for purchasing ThermaCELL Heated Insoles ProFLEX.
ThermaCELL Heated Insoles ProFLEX feature a wireless remote control
and removable, rechargeable state-of-the-art Lithium-Ion Polymer
batteries. With the touch of a button, you control the amount of
warmth under your feet while they stay protected inside your shoes or
boots.
ThermaCELL Heated Insoles ProFLEX keep your feet warm, not hot,
so they don’t sweat then freeze. Your Heated Insoles use an internal
thermostat to maintain a steady temperature inside of your shoes or
boots, keeping your feet around normal body temperature. They are
intended to be used in a cold setting; you are less likely to feel the heat
in a warm environment. These operating instructions provide clear and
concise directions on how to properly use your Heated Insoles.
ThermaCELL products, including the original ThermaCELL Heated
Insoles and ThermaCELL Mosquito Repellent, enable outdoor
enthusiasts to enjoy their favorite activities in comfort. We thank you
again for your purchase of ThermaCELL Heated Insoles ProFLEX and are
confident your cold weather activities will be more comfortable and
enjoyable than ever before.
Enjoy your purchase,
The ThermaCELL Product Group

Package Contents
The ThermaCELL Heated Insoles ProFLEX box contains two Heated Insoles (Figure 1), two cushioned
battery packs, one Smart Charging Case, one wall charger, one USB cable (Figure 2), one Remote
Control, one Lanyard (Figure 3), one Drawstring Travel Bag (not shown) and this Instruction Booklet.
Trimming Insoles for Exact Fit
ThermaCELL Heated Insoles ProFLEX may be trimmed to t shoes or boots if needed. If your footwear has
a removable insole, take it out and use it as a cutting guide. Be sure to follow the WARNING statement
printed on the bottom of the Heated Insoles.
WARNING: Cutting beyond solid line may cause damage to heater and will void warranty.
Charging and Recharging Batteries
For best results, ThermaCELL Heated Insoles ProFLEX must be fully charged before use. Charge the batteries
at room temperature. Insoles do not need to be taken out of footwear to remove the batteries. It may take
up to 4 hours to charge. Before proceeding, ensure hands are dry.
Directions:
1. Plug the USB Cable into the Smart Charging Case by inserting the micro USB connector (smaller
end). Then, plug the USB connector (larger end) into the wall charger. Connect the wall charger to
a power outlet. When there are no batteries in the Smart Charging Case, the two LEDs on the side
of the case will glow green.
a. Alternatively, you can plug the USB connector into a powered USB port rather than the
wall charger.
2. Insert the battery into the Smart Charging Case by following these steps:
a. Lay the Smart Charging Case on a at dry surface.
b. Hold the battery with the foam side facing up above the Smart Charging Case.
c. Place the battery inside the Smart Charging Case with the foam side facing up, so the
battery connector is facing the red Smart Charging Case connector (Figure 4). The battery
will be at a slanted position at this point (Figure 5).

Charging and Recharging Batteries (continued)
3. With the connectors aligned, slide the battery connector on to the Smart Charging Case
connector; push battery down until it clicks and locks into place. The battery should be fully
nested inside the Smart Charging Case.
4. Insert the second battery into the opposite side of the Smart Charging Case by following
steps 2 and 3 above.
5. The Smart Charging Case LEDs should glow orange when the batteries are connected to indicate
that they are charging. If either LED turns green, the battery on the side of the green LED is fully
charged. LEDs will only glow green when the batteries are fully charged inside the Smart
Charging Case. When glowing green, the batteries are then ready to be used in your Insoles.
6. After batteries are charged, disconnect the wall charger from the outlet or the USB connector from
the powered USB port and then disconnect the micro USB connector from the Smart Charging
Case. This process can be done in any order without damaging the unit.
7. Remove the batteries from the Smart Charging Case by following these steps:
a. At the end of the battery opposite the connector, you will feel a thin protruding hard tab
on the battery (Figure 6). Lift the battery by inserting nger under the tab and gently
pulling up just enough so you can insert the tip if your nger under the battery. Do not
attempt to lift batteries by grasping the battery's foam cushion as it could tear. Do not lift
the battery more than is required to insert a nger underneath the battery to grasp it.
b. Pull the battery in a straight line away from the Smart Charging Case connector (Figure 7).
c. Repeat steps 7a and 7b to remove the other battery.
Figure 6 Figure 7
Inserting Batteries into Insoles
The batteries can be inserted into the Insoles whether the Insole is in footwear or not. Insert the batteries
into the Insoles by following these steps:
1. Ensure Insole's battery compartment is facing up.
2. Hold the battery with the foam side facing up above the Insole battery compartment with the
battery connector facing the heel of the Insole.
3. Align the battery on top of the Insole battery compartment with the foam side facing up so that the
battery connector is facing the red Insole connector (Figure 8).
4. With the connectors aligned, slide the battery towards the Insole connector. Then slide the
battery connector into the Insole connector (Figure 9) and press the battery all the way down in to
the battery compartment. The battery will be fully nested inside the Insole battery compartment.
5. Repeat steps 1-4 with the other battery and Insole.
Note: Insoles default to the No Heat setting upon insertion of batteries, waiting for you to set the heat level
from your Remote Control.

Removing Batteries from Insoles
1. Reach with your nger to the front edge of the battery which is closest to the toe of the shoe or boot.
2. Just beyond the front edge of the foam you will feel a thin protruding hard tab on the battery. Lift
the battery by the tab just enough so you can insert the tip of one nger under the battery (Figure
10). Do not lift the battery more than is required to insert a nger underneath the battery to
grasp it. Do not lift the battery up any further until it is disconnected from the Insole's connector.
Do not attempt to lift batteries by grasping the battery's foam cushion as it could tear.
3. Gently pull the battery in a straight line away from the Insole (Figure 11).
Figure 10 Figure 11
Setting the Heat Level with Remote Control
The rst time that you use your ThermaCELL Heated Insoles ProFLEX, you will have to remove the clear
plastic tab from the Remote Control to activate the already installed battery.
1. Insert a battery into the battery compartment in each Insole (see instructions for Inserting Batteries
into Insoles). The Insoles default to the No Heat setting upon insertion of the removable batteries,
and a single ash of a green LED will ash intermittently in the battery compartment between the
battery and the Insole.
2. Select a heat setting by using the buttons on the Remote Control: High (111˚F), Medium (100˚F)
or No Heat (standby). The green LED light in the battery compartment on each Insole will ash
intermittently indicating the heat setting: one ash indicates No Heat, two ashes indicate
Medium Heat, and three ashes indicate High Heat.
3. The LED light on the Remote Control will ash one time to conrm a heat setting has been
transmitted to the Insole. The Remote Control can be used up to 7 feet from the Insoles. It can be
used both before inserting Insoles into footwear and while Insoles are being worn.
Note: The heating element in each Insole extends from the toe area to the ball of the feet. The arch and
heel areas are not heated.
Inserting Insoles into Footwear
Insert into shoes or boots with battery compartment facing up. Trim Insoles to t if needed. Please follow
additional directions on the bottom of the Insoles.
Turning Insoles Off
Long-term: When you are not using your Insoles for a prolonged period of time (many hours or longer),
remove the batteries from the Insoles. This is the only way to completely turn ThermaCELL Heated Insoles
ProFLEX off.
Short-term: When you are not using your Insoles for a short period of time (up to a few hours or when your
feet are warm), use the Remote Control's No Heat setting to put the Insoles into “standby” or “sleep” mode.
This will exhaust the battery at approximately 2% per hour. When heat is needed, simply press the High
or Medium button on the Remote Control to reactivate heat.

Helpful Hints for Using the Insoles
· Heated Insoles do not get “hot” to the touch and will not get as hot as disposable/chemical
warming pads. They are engineered to keep your feet from sweating then freezing, so that your
feet remain warm and comfortable. Heated Insoles maintain a steady temperature of 100˚ or
111˚F inside your boots or shoes (depending on the heat setting chosen), keeping your feet
around normal body temperature.
· For best results, use Heated Insoles in a cold environment. You are less likely to feel heat output
in a warm environment outside of footwear.
· For a better t, remove the insoles currently in your footwear (if removable), and replace with
Heated Insoles. Make sure footwear is not too tight, tightness naturally causes feet to get cold.
· Once Heated Insoles have been fully charged, they will provide up to ve hours of constant
heat on Medium. The outside temperature and insulation of footwear will affect run time.
· To prolong battery life, it is recommended that the Insoles be in the No Heat setting when the
user is engaged in strenuous activities. At high exertion levels, the body typically generates
enough heat to keep the feet warm.
· The Smart Charging Case should be used as a protective carrying case for the batteries.
· Maintaining a comfortable heat level while using your Heated Insoles depends upon proper
installation and activation of the Insoles, along with the type, t, insulation, and dryness of the
footwear and/or socks being worn.
· For best performance, it is recommended to wear well insulated boots and medium-to-
lightweight socks that wick away moisture. A very heavy sock will prevent heat from reaching
your foot. Avoid materials such as cotton that will retain moisture.
· For best results, turn Heated Insoles on at the rst sign of your feet getting cold.
· Before using Heated Insoles, make sure the inside of your shoes or boots are dry.
· The tabs at the heel of the Heated Insoles will assist in easy removal of the Insoles from shoes or
boots after use. Be sure to insert Insoles with the black tab at the heel sticking up.
· When the batteries are drained during operation, the Insoles will stop generating heat. It is then
time to replace or recharge the batteries. It is recommended that you keep an extra set of
batteries with you to extend the run time of the Insoles.
Care Instructions
· Store all contents of this ThermaCELL Heated Insoles ProFLEX product in a clean and dry place.
· Charge batteries fully before long-term storage and store in the Smart Charging Case. Recharge
the batteries every few months to maintain peak performance.
· Only use the Smart Charging Case to charge ThermaCELL Heated Insoles ProFLEX batteries.
· Do not damage the heating elements by excessively bending the Insoles.
· Cut the Insoles to size only as indicted in instructions and on bottom of Insole.
· Clean with a damp cloth only. Do not use chemicals or cleaning agents.
· Do not submerge in water. Insoles are highly water resistant, not waterproof. If Insoles become
submerged in water, air dry before attempting to use.
· Only air-dry the Insoles. Do not place them on radiators or any other hot surface. Let the Insoles
dry completely before charging and attempting to use again.

Important Information if Insoles are Not Heating
or Operating Correctly
Perform the following actions if the Insoles do not seem to be heating correctly:
1. Recharge the batteries in the Smart Charging Case until the LEDs on the Smart Charging Case turn
green (LEDs will only turn green when the batteries are fully charged).
2. Verify the LED on the Remote Control illuminates when any button is pushed. If not, replace the
battery in Remote Control.
3. After inserting batteries into the Insoles, select the High setting on the Remote Control. Verify
the Insole LED in the battery compartment ashes in groups of three. If not, see Remote Control
Reprogramming Instructions.
4. If Insoles are still not functioning, please contact ThermaCELL Customer Service.

Remote Control Reprogramming Instructions
If the Remote Control does not properly activate the Insoles per the instructions, you will need to
reprogram the Insoles with the Remote Control. ThermaCELL Heated Insoles ProFLEX and the Remote
Control are programmed at the factory so that your Remote Control will only operate your Insoles.
Please follow the directions below ONLY if you need to reprogram your Insoles with your Remote
Control. The following instructions are easiest to perform with one Insole at a time.
1. Insert fully-charged batteries into your Insoles.
2. The reprogramming button is located on the “T” in “ThermaCELL” printed on the top of each
Insole. Firmly press the “T” on the Insole rapidly two times, noting that the LED in the Insole
battery compartment illuminates as you press it. You have now entered reprogramming mode.
3. The Insole LED in the battery compartment will start ashing a sequence of one (1) long ash
followed by four (4) very short ashes to indicate the programming mode is in process. The ash
sequence will repeat three (3) times and then will time out.
4. If you do not see the ash sequence noted in step 3, you have pressed the button too slowly.
Repeat the process, pressing the button two times more quickly.
5. During this process, press any button located on the Remote Control (if you do not press a button
in time, simply repeat the process from Step 2). This will reprogram the Insoles with the Remote
Control.
6. Repeat Steps 2 and 3 with the other Insole. This will complete the reprogramming of your Heated
Insoles.
