motor, compressor, control switch.
< NOTE >
• There is a possibility of insufficient cooling due to clogging of the air filter. So make sure to first
check if the air filter is clogged or not.
• Check the power supply because of the possibility of power source failure.

entering water temperature is not exceeding 90 °F (32 °C).
