THANK YOU
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.

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 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.9.1
