Installation Instructions

Operator: Save these instructions for future use!

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

These Level-Temp Silent Operator relays are designed for use on electric heating equipment in conjunction withWhite-Rodgers low voltage thermostats.They are especially suitable for use on baseboards, wall insert heaters, etc. Some models also have an inductive rating to permit them to be used on motor loads where a time delay is desired.

Different models of these Silent Operator relays are available for voltage inputs of 120, 208, 240, 277, 347 or 600 volts. Since these relays are equipped with a self-contained transformer, the supply voltage used must agree with the voltage rating of the relay.

When required, two or more of these Silent Operator relays can

DESCRIPTION

be operated by one low voltage heating thermostat.These Silent Operator relays have been carefully adjusted at the factory. No attempt should be made to adjust them in the field.

If in doubt about whether your wiring is millivolt, line, or low voltage, 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.

precautions

!CAUTION

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

!WARNING

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