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

The Fan control is a normally open SPST switch which closes on a rise in temperature and has an adjustable temperature setting.

The Limit control is a normally closed SPST switch which opens on a rise in temperature to limit the maximum allowable temperature and has an adjustable tempera- ture setting.

DESCRIPTION

This control is particularly well suited for use where space limitations are a problem. The small bimetal sensing element is completely in the air stream to give quick response. This control has a snap-action switch with heavy duty contacts.

THIS CONTROL MUST BE INSTALLED BY A QUALI- FIED INSTALLER.

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.

This control has been accurately calibrated at the factory. Any attempt to re-calibrate this control will void the White- Rodgers warranty.

!WARNING

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

If in doubt about whether your wiring is millivolt, low or line voltage, have it inspected by a quali- fied heating and air conditioning contractor or a licensed electrician.

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.

Label all wires prior to disconnection when ser- vicing controls. Wiring errors can cause improper and dangerous operation.

Following installation or replacement, follow appliance manufacturers’ recommended instal- lation/service instructions to insure proper op- eration.
