FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY
BEFORE INSTALLING OR OPERATING THIS CONTROL COULD CAUSE
PERSONAL INJURY AND/OR PROPERTY DAMAGE.
INSTALLATION INSTRUCTIONS
TYPE 1127
HOT WATER CONTROL
Surface Type - S.P.D.T.
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 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.
INSTALLATION
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.
PRECAUTIONS
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.
