INSTALLATION

MOUNTING INSTRUCTIONS

The enclosure must be mounted in a location that will

allow the cover to be completely opened right up

against the wall.

Fasten the four brackets to the four mounting holes on

the back of the enclosure, using the four screws

provided with the brackets. Then mount the enclosure

on the wall by inserting screws through the brackets’

adjustment slots, into the wall. Make sure to position

the enclosure so that the power supply cord extends out

of the bottom section of the enclosure.

The bracket slots also serve to adjust the position of the

controller. Once you have adjusted the controller

position, tighten the four mounting screws.

CONNECTIONS

To connect the controller, refer to the wiring diagram enclosed with this installation manual.

1. Set the voltage switch to the appropriate line voltage.

2. Drill access holes on the bottom of the enclosure only. Do not drill holes on the side or

the top of the enclosure.

3. It may be necessary to install a transformer on the heating stage in order to supply the

appropriate voltage to the heating unit.

Alarm Connection

There are two types of alarms on the market. One type sets off when current is cut off at its

input; the other sets off when current is supplied at its input. For the first type of alarm, use the

NO terminal as shown on the wiring diagram. For an alarm of the second type, use the NC

terminal.

WARNING

ALL WIRING MUST BE DONE BY AN AUTHORIZED ELECTRICIAN AND

MUST COMPLY WITH APPLICABLE CODES, LAWS AND REGULATIONS. BE

SURE POWER IS OFF BEFORE DOING ANY WIRING TO AVOID

ELECTRICAL SHOCKS AND EQUIPMENT DAMAGE.
