HOT WATER CONTROL

Direct Immersion - Adjustable Differential

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

This control, designed for use on hot water heating systems, has an element that is immersed directly into the boiler water. This feature gives unusual speed of response to rapid changes of water temperature thereby preventing thermal lag.

It has open on rise contact action. This control may be used as a high limit or as a low limit control.

These controls have special contacts which are suitable for use on low voltage and millivolt (thermocouple generator type) circuits as well as line voltage gas valve and motor loads.

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 components 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.

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 voltage. Higher voltage will damage control and could cause shock or fire hazard.

If the boiler manufacturer recommends a control location, then follow such recommendations. If none are offered, the following information shows suggested locations.

For high limit service, the control should be located in the hottest part of the boiler. This is usually near the top of the boiler. A high limit control should not be in the same section of the boiler that contains the heater or the pipes that heat domestic hot water.

INSTALLATION

For low limit or operating service, the control should be so located, that it responds to the temperature of that section of the boiler that heats domestic hot water.

When tightening the control into the boiler, care should be taken to apply all leverage on the hexagonal nut so as not to injure the diaphragm or control mechanisms.
