INSTALLATION INSTRUCTIONS
PRECAUTIONS
This Evaporative Cooler Control has a rain-proof enclo-
sure and can be used with either 120 VAC or 240 VAC
systems. It was designed for use with White-Rodgers
1F51-619, 1F51W-619, or 1D51W-632 Thermostats to
provide automatic temperature and ventilation control
and remote fan speed selection of an evaporative cooler
with 2-speed fan. The pump relay is automatically oper-
ated to allow wetting of cooler pads before starting fan.
If in doubt about whether your wiring is millivolt, line, or low
voltage, have it inspected by a qualified heating and air
conditioning contractor, electrician, or someone familiar
with basic electricity and wiring.
Do not exceed the specification ratings.
All wiring must conform to local and national electrical
codes and ordinances.
This control is a precision instrument, and should be
handled carefully. Rough handling or distorting compo-
nents could cause the control to malfunction.
