Test Run
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
(63°F)
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
