module (CCM) also monitors the high pressure switch,
and will allow one automatic retry (after soft lockout
delay) before disabling the compressor in a hard lockout
(requires manual reset). If hard lockout does occur,
the ALR terminal on the CCM will become active with
24V, which will power the high pressure relay within the
wall-mount unit, breaking a digital input to the LC6000
controller—signaling a high-pressure situation to the
system.

Pressure Service Ports

High and low pressure service ports are installed on
all units so that the system operating pressures can be
observed. A pressure table covering all models can be
found on page 19. It is imperative to match the correct
pressure table to the unit by model number.
This unit employs high-flow Coremax valves instead of
the typical Schrader type valves.
WARNING! Do NOT use a Schrader valve core removal
tool with these valves. Use of such a tool could result
in eye injuries or refrigerant burns!
To change a Coremax valve without first removing the
refrigerant, a special tool is required which can be
obtained at www.fastestinc.com/en/SCCA07H. See the
replacement parts manual for replacement core part
numbers.

Outdoor Fan Motor

Due to design considerations of the condenser section
of the wall-mount unit, placement/clearance of the
motor/fan blade is critical to heat dispersal. Should a
change of motor or fan blade be necessary, please view
Figure 23 for proper clearance adjustment.
