Cold Therapy units consist of a cooler tank filled with ice and water, a double hose and then a pad designed to contour the body part to be treated Water circulates out one of the hose sides and then back the other hose side.
If your cold therapy unit (CTU) isn't working, here are the steps you can take to troubleshoot:
1) Verify that the machine is properly filled to the lines with water and ice. Ice must be cubed only; not crushed.
2) The pump in the lid of the unit should hum and begin pumping when the unit is filled and plugged into a wall outlet. If it doesn't, make sure the wall outlet is working (test with another appliance) and that the AC adapter for the CTU is plugged into its socket in the lid of the cooler
3) The cooler must be positioned no higher or lower than 2" of the body part being treated. For example, if it's being used to treat the knee, the CTU must be placed on a table at approximately knee height as opposed to on the floor.
4) Poor performance is often the result of a plugged filter. The filter is located at the tip of the pump on the inside of the CTU lid. It usually unscrews and can be rinsed under water.
5) The pad is designed to maintain a temperature of 45-55 degrees. That is the optimal temperature for treatment and reduces the likelihood of frostbite.
6) Pads do not inflate with water. Rather the water just circulates gently through the pad.
7) Poor water circulation can be due to kinks in the tubing. Run your fingers along the tubing to be sure there are no kinks in it.
The hose connects to the pad with watertight fittings fastened with small spring connectors. Make sure the hoses and spring connectors are completely seated.
If the CTU still isn't working, it should be returned for replacement.
You'll need the serial number and date of purchase of the unit. The serial number can be found on the top of the cooler lid beneath the hose. Pads have serial numbers also. The nine digit serial number will be on the pad near the hose connector.
