Operator:  Save these instructions for future use!

FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY BEFORE
INSTALLING OR OPERATING THIS CONTROL COULD CAUSE PERSONAL
INJURY AND/OR PROPERTY DAMAGE.

DESCRIPTION

The Type 8A04-1 Fan Relay is for use with low voltage thermo-
stat to provide a 24 volt control circuit for operating a line voltage
fan motor or other load.

The relay has SPDT switch action to permit use with either single
or two-speed motor.

Diagrams presented on back of this sheet show various systems
that provide the required 24 volt power supply for operating the
coil of the Fan Relay.

To prevent electrical shock and/or equipment dam-
age, disconnect electric power to system, at main fuse
or circuit breaker box, until installation is complete.

Do not use on circuits exceeding specified voltages.
Higher voltages  will damage control and could cause
shock or fire hazard.

PRECAUTIONS

CAUTION

If in doubt about whether your wiring is millivolt, line, or low
votage, have it inspected by a qualified heating and air condi-
tioning 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 components could cause
the control to malfunction.
