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.

This control is a dual-function control having a tempera- ture regulating control in series with a high-limit control.

The temperature control is a SPDT switch which opens on a rise in temperature and will control one or two heating elements.

DESCRIPTION

The limit control is a normally closed DPST switch which opens on a rise in temperature to limit the maximum allowable temperature. It has manual reset.

Both switches are calibrated to meet the requirements for typical residential type storage tank water heaters.

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.
