Drain Pan Foam
Genuine Comfort units are equipped with the unit sitting on a drain pan. The drain pan is specifically designed with a hole that allows for proper drainage.
Water is produced when the unit is calling for cooling, the refrigerant vapor is liquefied and the drain pan collects the condensate. Additionally, the coil drips water into the foam and overflows to the pan. The majority of the water is effectively picked up by the slinger fan, which helps to cool the coil. This not only aids in the cooling process but also contributes to the overall efficiency of the unit.
It is important to note that the unit installed in the wall sleeve must have a slope towards the grille. This slope allows for the proper direction of water flow, ensuring that it can easily drain through the hole. In some scenarios, the slope is towards the room and causes leaking. Another method is to place a wooden block to tilt the unit back if a slope does not exist.
This valve plays a crucial role in detecting and preventing water overflow in the drain pan during low temperatures. When the temperatures drop, the valve will lift upwards and the rubber plug at the bottom of the valve will rise. This upward movement allows the water to completely drain from the pan. This safety measure is in place to ensure that the water in the drain pan does not remain stagnant and freeze during low temperatures. By allowing the water to drain fully, the valve helps to prevent any potential damage or freezing that could occur.
*Our technology allows the valve to begin to lift up when the outdoor temperature reaches
20oC. The valve will reach the limit of 7mm height when the outdoor temperature is 0oC. This means the valve will allow water to drain and prevent the water from freezing in the pan.
If your unit is constantly cooling or running for long periods of time in order to reach the desired temperature, it is likely that there is insufficient cooling. This could be due to issues with insulation or other environmental factors that are causing air to leak, preventing it from maintaining the cool temperature set by the unit. As a result, the unit will produce more condensate or water vapor. In the event that the drain pan foam and valve are unable to drain all of the water, a drain hole is provided at the back of the unit. This allows any excess water to seep out through the hole. This is the last measure in place to avoid overflow of water in the pan.
*Please note the high-resistance firm foam noted below should not be removed from the unit.
