CAUTION
!
When a failure occurs during automatic testing, the unit will suspend operation awaiting oper-
ator intervention.
CAUTION
!
When Pre-Trip test Auto 2 runs to completion 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 result 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 suc-
tion 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 dis-
charge service valves closed (front-seated). 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 programming 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.
