WARNING

1. All electric heat kits have lugs for connection of high

voltage power supply. Insert the power leads into the

lugs (either on the terminal block or circuit breaker)

and tighten. The power must be routed through a strain

relief as they enter the cabinet. For two power supply

electric heat kits (all circuit breaker connections), be

sure to connect the correct power supply to the correct

circuit breaker – check the air handler rating plate for

Minimum Circuit Ampacity and Maximum Overcurrent

Protection electrical ratings of each circuit.

2. Connect the ground wire from the power supply to the

ground lug provided in the air handler. For two power

supply electric heat kits, one ground lug is provided

with the air handler and the second ground lug is supplied

with the electric heat kit (on the circuit breaker

mounting plate). Use proper torque to secure the ground

wire to the ground lug.

3. For low voltage connections, remove the female multi-

pin connector with the jumper wire provided with the

air handler from the male multi-pin connecter provided

with the air handler. Insert the female multi-pin

connector provided with the electric heat kit into the

male multi-pin connector provided with the air handler.

Note: it can be inserted in one position only.

4. FOR ALL THREE PHASE APPLICATIONS: Wire the terminal

block leads to the transformer as per the wiring diagram

on the heat kit. Insert single and three phase power

leads into the lugs provided on the terminal block and

the circuit breaker respectively, and tighten.

5. FOR 25kW AND THREE PHASE HEAT KIT APPLICATIONS:

Install the wiring diagram provided with the heat kit in

a prominently visible location on the exterior of the

unit.

6. FOR ALL HEAT KITS: Mark an “X” on the wiring diagram

according to the number of heater element rows

installed.

1. Double check all electrical connections and screws to

ensure proper installation.

2. Replace the upper access panel on the air handler.

3. Make sure all circuit breakers and electrical power

supply are on.

4. Install an ammeter on the power supply(s) to the air

handler.

5. Turn the room thermostat setting to emergency heat

and adjust the set point about 1°F above actual room

temperature to “call for heat”.

6. The blower should turn on within the first 10 seconds

and up to the first 10kW of electric heat should turn on

within 10-30 seconds.

7. Turn the room thermostat setting to off. The blower

and all electric heat should turn off within 70 seconds.

Steps 8-10 are only for electric heat kits

with more than 10kW.

8. Turn the room thermostat setting to emergency heat

and adjust the set point about 5°F above actual room

temperature to “call for heat”.

9. The blower should turn on within the first 10 seconds,

up to the first 10kW of electric heat should turn on within

10-30 seconds, and the additional electric heat above

10kW should turn on within 10-30 seconds after the room

thermostat calls for second stage electric heat (this may

vary depending on the room thermostat).

10.Turn the room thermostat setting to off. The blower

and all electric heat should turn off within 70 seconds.

11.If the blower and / or electric heat do not cycle

appropriately, disconnect all power supplies and

troubleshoot per service manual instructions.
