b. Check for refrigerant gas leakage from the refrigerant line.
1. After the blower motor stops, wait at least 15 minutes.
2. Using a gas leak detector, check that gas is not leaking from the refrigerant line.
If leakage is found, tighten parts or replace damaged parts as necessary to stop the leak.
c. Check for refrigerant gas leakage from the drain hose.
1. Hold the gas leak detector so that the sensor is under the drain hose, as shown in the illustration.
2. Check that gas is not leaking from the drain hose.
If leakage is found, tighten parts or replace damaged parts as necessary to stop the leak.
d. Check for refrigerant gas leakage from the cooling unit.
1. Remove the blower motor control from the unit. Insert the gas leak detector's sensor into the unit.
2. Check that gas is not leaking from the unit.
If leakage is found, tighten parts or replace damaged parts as necessary to stop the leak.
e. Check for refrigerant gas leakage from the pressure switch.
1. Disconnect the pressure switch connector and wait approximately 20 minutes.
2. Using a gas leak detector, check that gas is not leaking from the pressure switch.
If leakage is found, tighten parts or replace damaged parts as necessary to stop the leak.
f.
Repeat all steps above 2 to 3 times.
