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 that all checks 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 17°C
You can't use the remote controller to turn
on the COOL function when the ambient
temperature is below 17°C. In this instance,
you can use the MANUAL CONTROL button
to test the COOL function.
1. Locate the MANUAL CONTROL button on
the right-hand side panel of the unit. See
Fig.8.1.
2. Press the MANUAL CONTROL button one
time to activate FORCED AUTO mode.
3. Press the MANUAL CONTROL again
to activate FORCED COOLING mode.
