CAUTION
When a failure occurs during automatic
testing, the unit will suspend operation
awaiting operator intervention.
CAUTION
When Pre-Trip test Auto 2 runs to comple-
tion without being interrupted, the unit will
terminate pre-trip and display “Auto 2”
“end.” The unit will suspend operation until
the user depresses the ENTER key!
CAUTION
Allowing the scroll compressor to operate
in reverse for more than two minutes will re-
sult in internal compressor damage. Turn
the start-stop switch OFF immediately.
CAUTION
To prevent trapping liquid refrigerant in the
manifold gauge set be sure set is brought to
suction pressure before disconnecting.
CAUTION
The scroll compressor achieves low
suction pressure very quickly. Do not use
the compressor to evacuate the system
below 0 psig. Never operate the
compressor with the suction or discharge
service valves closed (frontseated). Internal
damage will result from operating the
compressor in a deep vacuum.
CAUTION
Take necessary steps (place plywood over
coil or use sling on motor) to prevent motor
from falling into condenser coil.
CAUTION
The unit must be OFF whenever a program-
ming card is inserted or removed from the
controller programming port.
CAUTION
Use care when cutting wire ties to avoid
nicking or cutting wires.
CAUTION
Do not allow moisture to enter wire splice
area as this may affect sensor resistance.
