INSTALLATION INSTRUCTIONS

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

These controls have close-on-rise switch action and are designed for use on hot water heating installations. They prevent operation of the circulator or unit heater fan if the boiler water is not hot enough for proper heating.

Models are available with either horizontal or vertical well. Some of these models also have excess capillary stored within the enclosure, permitting them to be used with wells having either a standard or extended shank.

Another model, ideal for replacement purposes, has a slotted case and excess capillary stored within the enclo- sure. This control can be used with either a standard or extended shank well, on either horizontal or vertical well installations.

THESE CONTROLS MUST BE INSTALLED BY A QUALIFIED INSTALLER.

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.

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

WARNING

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

PRECAUTIONS

CAUTION

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

Following installation or replacement, follow appliance manufacturer’s recommended instal- lation and/or service instructions to insure proper operation.

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.

Shut off main gas to heating system until instal- lation is complete.
