The proper location of a heavy-duty room thermostat is very important to ensure good
performance.
Make sure the thermostat is in a place where air circulates around it freely.
•
Never install the thermostat on or near an outside wall.
•
•
Keep the thermostat away from windows and doors.
Do not locate the thermostat too close to a strong light or any other false source of
•
heat such as direct sunlight, steam lines, etc.
•
Mount the thermostat on a post or partitioning wall, but make sure that there are no
pipes or duct work in that wall or in the other side of the wall.
•
Mount in a vertical position.
WARNING:
Disconnect the power supply before wiring connections are made to
avoid possible electrical shock or equipment damage.
Make all wiring connections using copper conductors only and in accordance with the
National Electrical Code and local regulations. Loads exceeding the rating of the
thermostat should be handled by means of a relay or motor starter.
•
Install an electrical conduit box for the thermostat.
•
Pull the required wires to this box.
CAUTION:
Use terminal screws furnished (No. 8-32 × 1/4-inch binder head
screw). Substitution of other screws can cause problems in making
proper connections.
There is no servicing of the thermostat. Replace if inoperative.
