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 the White-Rodgers
1F51-619 or 1F51W-619 Thermostat to provide auto-
matic temperature and ventilation control and remote fan
speed selection of an evaporative cooler with 2-speed
fan. The pump relay is automatically operated 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.
