FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY BEFORE
INSTALLING OR OPERATING THIS CONTROL COULD CAUSE PERSONAL
INJURY AND/OR PROPERTY DAMAGE.
Type 1131 controls are designed for use on hot water
heating installations. They have single-pole, double-throw
switch action, offering open-on-rise terminals as well as
close-on-rise terminals. These controls may be used as a
high limit, low limit, circulator, or combination low limit-
circulator control.
Models are available with either horizontal or vertical well,
and with either fixed or adjustable differential. 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 both
a slotted case and excess capillary stored within the
enclosure. This control can be used with either a standard
or extended shank well, on either horizontal or vertical
well installations.
THIS CONTROL 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.
Convertible controls have a Knockout Plate on back of
case (secured by Hex Nut on Horizontal models, and by
Knockout Plug on Vertical models). To convert from
Horizontal to Vertical:
1. Remove control cover. Then remove bottom knockout.
2. Remove Hex Nut (inside control) from Well Mounting
Stem. (To loosen, hold Hex Nut inside while turning
Hex Nut on back of control counterclockwise.)
