DOUBLE-CHECK PIPE CONNECTIONS
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.
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.
IF AMBIENT TEMPERATURE IS BELOW
63°F (17°C)
You can’t 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.8.1
3. Perform Test Run as normal.
