The SoClean replacement Injection Hose assembly includes: Check Valve, Injection Fitting and Tubing. The Check Valve prevents water in the CPAP humidifier water chamber from backing up into the SoClean machine. If at any time water can be seen in the clear tube (Check Valve), replace immediately. It should be replaced every 6 months or the SoClean display shows the "Order Filter Kit" message.
Replacing The Check Valve Assembly
Remove old Check Valve
Grasp the barrel of your current Check Valve firmly, and pull the tubing away from the barrel stem. It may be neccessay to use a twisting motion to free the tubing from the stem.
After one side of the tubing has been disconnected from the Check Valve, repeat step A to disconnect the tubing from the other side.
2. Position new Check Valve
3. Install new Check Valve
Your Check Valve should be facing the correct direction, grasp the barrel and insert the stem as far as possible into the end of the tubing. The tubing should be nearly touching the barrel of the Check Valve. A thin film of dish soap on the stem can be used to help, if necessary.
Repeat above step for the remaining side of the Check Valve
Return on warranty issues only.
2. Position the injection fitting onto the port of your reservoir, allowing the smaller hose to enter into and rest on or near the bottom of the reservoir.
3. It may be necessary to trim off some of this smaller hose to achieve the best fit.
Note: If you experience difficulty inserting the small hose into the reservoir, please visit our page to see how this can be done with a number of different style humidifiers.
2. Reconnect the main CPAP hose to the top of the injection fitting.
