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 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-

WARNING
INSTALLATION
The proper location of a heavy duty room thermostat is
very important to assure good performance. The following
general rules will help in determining the proper location:
1. Make sure that it is in a place where air circulates
around it freely. This is important.
2. Never install it on or near an outside wall.
3. Keep it away from windows or doors.
4. Don’t locate it too close to a strong light or any other
false source of heat such as direct sunlight, steam
lines, etc.
5. Mount it on a post or a partitioning wall, but make sure
that there are no pipes or duct work in that wall or
directly behind it.
6. If the electrical conduit leads into a cooler or a warmer
room, plug up the space around the wires in the conduit
with rock wool.
