TIMERS FOR WATER SPRAY DEFROST CONTROL
WITH PUMP-DOWN DRAIN OR FAN DELAY CYCLES
Defrost initiation: 1 to 8 cycles per day, at least 3
hrs. between cycles. Delay or pump-down cycles:
0 to 30 min. in 3-min. increments; for stopping
fans, reducing refrigerant pressure, or hot gas
pump-down cycle. Defrost cycles: 3 to 45 min.
in 3-min. increments. Drain or fan cycles: 3 to 15
min. in 3-min. increments.

Refrigeration/Defrost Control
Microprocessor-based controller manages all temperature and defrost
functions in a typical piece of commercial refrigeration equipment,
replacing up to 5 controls. Features 2 NSF-approved temperature
sensors for the case and the evaporator, and 4 relay outputs for
compressor, fan, defrost, and alarm. Line voltage input power is select-
able 120/208/240VAC at 50/60 Hz, enabling use on a wide range of
equipment. UL873 NSF Certified. Replacement sensor includes 10-ft.
cable. Sensor can be expanded to 100 ft. using additional 18-ga.
shielded cable. For use with electric, hot gas, or timed-off defrost appli-
cations controls.
