Startup
(See back of the manual for startup form.)
Before startup of the condenser or
condensing unit, make sure that the
following items have been checked.
1. Verify that electrical power is available
to the unit.
2. Verify that any remote stop/start device
connected to the unit controller is
requesting the unit to start.
Confirm the compressor is operating within
tolerance.
While performing the check, use the startup
form to record observations of amps and
refrigerant pressures.
When all is running properly, place the
controller in the Run mode and observe the
system until it reaches a steady state of
operation.
Compressors
All compressors are equipped with
crankcase heaters, which should be
energized at least 24 hours prior to cooling
operation of the compressor.
3-PHASE ROTATION
Rotation must be checked on all
MOTORS AND COMPRESSORS of
three phase units. Condenser fan
motors should all be checked by a
qualified service technician at startup
and any wiring alteration should only
be made at the unit power
connection.
COMPRESSOR ROTATION
Scroll compressors are directional
and will be damaged by operation in
the wrong direction. Low pressure
switches on compressors have been
disconnected after factory testing.
Rotation should be checked by a
qualified service technician at startup
using suction and discharge pressure
gauges and any wiring alteration
should only be made at the unit
power connection.
ELECTRIC SHOCK
Electric shock hazard. Shut off all
electrical power to the unit to avoid
shock hazard or injury from rotating
parts.
QUALIFIED INSTALLER
Improper installation, adjustment,
alteration, service or maintenance
can cause property damage,
personal injury or loss of life. Startup
and service must be performed by a
Factory Trained Service Technician.
