Testing
DOUBLE-CHECK PIPE CONNECTIONS
IF AMBIENT TEMPERATURE IS BELOW
63°F (17°C)
5. After the Test Run is successfully complete, and
you confirm all check points in List of Checks to
Perform have PASSED, do the following:
a. Using remote control, return unit to normal
operating temperature.
b. Using insulation tape, wrap the indoor
refrigerant pipe connections that you left
uncovered during the indoor unit installation
process.

Manual control button
During operation, the pressure of the refrigerant
circuit will increase. This may reveal leaks that were
not present during your initial leak check. Take time
during the Test Run to double-check that all
refrigerant pipe connection points do not have leaks.
Refer to Gas Leak Check section for instructions.
You cannot use the remote controller to turn on
the COOL function when the ambient
temperature is below 63°F. In this instance, you
can use the MANUAL CONTROL button to test
the COOL function.
1. Lift the front panel of the indoor unit, and
raise it until it clicks in place.
2. The MANUAL CONTROL button is located
on the right-hand side of the unit. Press it 2
times to select the COOL function. See Fig.9.1.
3. Perform Test Run as normal.
