INSTALLATION INSTRUCTIONS

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 is designed for use on Hot Water Heating systems.

The highly sensitive Hydraulic-Action element is held snugly in contact with the pipe or tank to provide quick response to changes in water temperature.

Type 1127 has single-pole, double-throw switch action, offering terminals that have open-on-rise switch action as well as close- on-rise switch action. This control may be used as a high limit control, low limit control, circulator control, or as a combination low limit and circulator control.

PRECAUTIONS

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.

WARNING

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

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.

If the boiler manufacturer recommends a control location, follow such recommendations. If none is offered, the following informa- tion gives suggested locations.

On a domestic heating system, surface mounted controls may be attached to either a horizontal or a vertical riser approxi- mately 18 inches above the boiler.

On a unit heater application, they may be attached to the base of the coil directly in the air path or on the return line.

INSTALLATION

Installation Rules:

1.Remove the insulation on the pipe or tank where the control is to be mounted.

2.All rough spots, scale, rust, or paint should be removed with a file or similar tool.

3.Mount the control to the pipe by means of the two clamps provided. They should be pulled up snugly.

4.Replace the insulation, entirely embedding the shield which is around the sensitive element of the control.
