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- 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 volt- ages. Higher voltages will damage control and could cause shock or fire hazard.

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.
