Therm-X Assembly Guide
A complete tutorial on unboxing, assembling, using, and returning your Therm-X iceless cryotherapy system.
About the Therm-X
After an injury or surgery, your body initiates a biological response to remove or heal damaged cells. This response is called inflammation — a defense mechanism that produces pain and swelling as it works. Although inflammation signals the start of healing, it can persist longer than needed and cause more harm than good.
A combination of cryotherapy and compression can reduce inflammation, pain, stiffness, and swelling, and improve range of motion — allowing for a more efficient recovery. Improved pain control also produces a greater likelihood of independence from narcotic (opioid) use.
The Therm-X is an iceless cryotherapy system that helps you recover after surgery. It plugs into a standard wall outlet and circulates 40-degree water to a thermal garment worn over your surgical site, effectively "icing" that site without the mess of bagged ice.
Overview
Assemble Before Surgery
Completely assemble and test-drive the Therm-X before your procedure.
Set it up in the room where you'll spend most of your recovery time.
Use Following Surgery
Apply as frequently as needed — the unit self-regulates on a 30-on / 30-off cycle.
Many patients use it most of the day and sleep with it at night through physical therapy.
Return When Complete
Once treatment is finished, follow the packing and shipping instructions to return the unit.
Unbox Your Therm-X
Keep the box and all packing supplies — including the pink Styrofoam packaging — to ship the unit back to New England Medical Solutions when treatment is complete.
Remove all contents from the box and confirm everything on your delivery list is present:
- Main Unit
- Power Supply
- Power Cord
- Umbilical Hose
- Coolant (×2)
- Instruction Manual
- Extremity-Specific Thermal Garment
- DVT Sleeves (if prescribed)
You'll receive only one extremity-specific thermal garment (shoulder, back, hip, knee, elbow, or ankle). DVT sleeves are only included if DVT prophylaxis was prescribed — check your delivery list to confirm.
Assembly
Follow these steps in order. Each connection should make an audible click — that's how you know it's secure.
-
Remove cap and add coolant to the red line, then replace the cap.
Do not overfill — the red line is the maximum.
-
Attach the power cord from the power supply to the back of the main unit until you hear a "click."
-
Attach the fittings from the umbilical hose to the front of the main unit until you hear a "click."
-
If using DVT, fully insert the open end of the tubing into the DVT connector on the front of the main unit.
-
If using DVT, securely attach the DVT garment(s) to the calf.
-
Secure the thermal garment to the body.
Reference your extremity-specific thermal garment guide.
-
Attach the 3 fittings from the hose to the thermal garment until you hear a "click."
Assembly is complete.
Start Treatment
Tap "Start Treatment"
From the home screen, select Start Treatment to begin the cycle.
Garment Inflates
The garment inflates and cold coolant begins to circulate. The Treatment Running screen displays settings, a progress bar, and timer.
Pause or Stop Anytime
Use the pause button to suspend the cycle and resume later, or stop to return to the home screen.
No Reprogramming Needed
Your treatment cycle saves automatically — just hit Start Treatment to use it again.
The unit will run automatically through the end of the prescribed cycle. You do not need to reprogram the cycle each time you use the Therm-X.

Precautions & Warnings
Read all precautions before operating the Therm-X. These reduce the risk of fire, electric shock, and personal injury.
General Precautions
- Never push objects of any kind into the Therm-X through the exterior case.
- Never spill liquid on the Therm-X. If a spill occurs, clean immediately.
- Do not overfill the reservoir — fill only to the red line inside the filler neck.
- If the Therm-X gets wet, unplug it, wipe with a dry cloth, and allow it to dry before use.
- Only operate with the supplied power cord and power supply.
- Unplug the Therm-X when not in use.
- Do not operate if the unit is damaged or leaking fluid.
- Do not operate with a damaged or frayed power cord.
- Use indoors only — not in wet environments or humidity above 60%.
- Do not spray with water, solvents, or cleaners.
- Do not drop or impact the unit.
- Do not pull cords or hoses or place stress on the unit.
- Keep away from equipment that generates electromagnetic interference.
- Do not smoke or use garments near an open flame.
- Do not stick fingers or objects into the reservoir.
- Do not drink or ingest the coolant.
- Keep the side vents clear. Use compressed air to remove dust once a year.
- Do not modify the Therm-X. Service is restricted to authorized personnel.
Important Warnings
- If unusual swelling, skin discoloration, or discomfort occurs, immediately discontinue use and consult your healthcare professional.
- Follow the prescribed instructions of your healthcare professional for treatment regimen, area, frequency, and duration.
- A licensed healthcare practitioner must select the correct regimen for use.
- Patients vary in sensitivity to cold — make regular checks on patient comfort.
- Therapy garments must be initially selected by a healthcare professional.
- Do not apply the therapy garment so tightly as to restrict blood or fluid flow.
- Use only sterile garments over wounds or breaks in the skin.
- Inspect garments for cleanliness and damage before each treatment. Do not use a damaged garment — it may leak.
- Do not attempt to sterilize the Therm-X or therapy garments.
- Apply dressings under the therapy garment lightly.
- Do not allow the garment or hose to contact sharp objects.
- Apply the wrap correctly before initiating therapy — incorrect application may cause it to "balloon" and damage the wrap.
- Immediately stop compression therapy if you experience discomfort, numbness, or tingling.
- Use only the approved Therm-X coolant.
- All compression therapies must be turned OFF when the wrap is removed.
- Do not use the calf DVT therapy with the foot DVT garment — this is not an effective or approved treatment.
- Do not use the foot DVT therapy with the calf DVT garment — this may cause harm.
- Use only in environments of 60°–80°F with humidity below 60%.
- Do not use in confined spaces — adequate airflow must be maintained.
- Air bubbles trapped in the system may negatively affect performance.
- Never remove warning or caution labels.
- May cause serious burns. Do not use over sensitive skin or in the presence of poor circulation. Unattended use by children or incapacitated persons may be dangerous.
