During operation, the pressure of the
refrigerant circuit/piping will increase. This
may reveal leaks that were not present during
your initial leak check. Take time during the Test
section for instructions.
If the ambient temperature is below
60°F (16°C), the remote controller cannot be
used to turn on the COOL function. In this
instance, you will need to use the MANUAL
CONTROL BUTTON to test the COOL
function. Follow the steps below to access
this function:
Lift the front panel of the indoor unit,
and continue to raise it until it clicks
into place and becomes
self-supporting.
The MANUAL CONTROL BUTTON is
located on the right-hand side of the
unit (Refer to Fig 9.1). Press it 2 times
to select the COOL function.
Perform Test Run as normal.
