3 PHASE SCROLL COMPRESSOR ROTATION
CVD2075 ONLY
A trained and qualified technician must verify
compressor rotation at equipment startup or
compressor warranty will be void. Incorrect rotation of
a scroll compressor can be identified by:
Noisy compressor operation
Elevated suction pressure
Low discharge pressure
Compressor trips on overload protector
To change compressor rotation, reverse (exchange
locations) any two incoming power supply leads.
CONDENSING UNIT HEAT OF REJECTION
Ice machines, like other refrigeration equipment, reject
heat through the condenser. It is necessary to know
the amount of heat rejected by an ice machine when
determining the additional BTUH requirements for air
conditioning equipment.
Self-contained air-cooled ice machines add the total
BTUH load to a conditioned space.

Ice Machine head sections add an
insignificant amount of load to a conditioned space.
