7. Open heater package and remove heater module; secure heater
module to standoffs on blower inlet with (3) bolts provided (see
Fig. 3). Adjust mounting position so that all hardware and
sheetmetal clears the heating element wire by at least 1/4 in.
Reinstall heater/blower assembly.
8. Reinstall rear motor support bracket and attached motor wiring. Reinsert motor power plug and speed tap plug into motor. The connectors are polarized to prevent mis-wiring.
9. Remove heater wiring cover plate from interior partition between blower and control box (See Fig. 4) and install heater wiring plug attachment plate provided with heater.
10. Remove unit front panel to access unit control box compartment.
11. Open heater package and remove heater control panel; set heater control panel on top of unit (See Fig. 5).
12. Heater control panel will have black and yellow power wires
ending in panel mounted plugs; reach through large rectangular
opening in control panel and snap these plugs into mating openings
in heater wiring plug attachment plate installed in step 9 above (See
Fig. 4).
13. Rotate heater control panel into unit control box area and locate it into top left corner of control box; secure heater control panel to unit control box with (4) screws provided (See Fig. 6).
14. Open flexible “fish paper” insulation cover provided with unit
control box and route heater low voltage wires along the bottom of
the unit control box. Route low voltage leads from heater relay(s)
through hole in unit control box and into low voltage splice box.
Minimum Airflow (CFM)
(See Fig. 6 and Fig. 7.) dress wires and secure them to existing unit
control wires with wire ties provided .
15. Re-close flexible “fish paper” insulation cover; insure unit black and yellow power “pigtails” from contactor are properly routed through insulation cover (See Fig. 8).
16. Attach the adhesive backed wiring label provided with the heater to the back of the access panel near the unit wiring label (See Fig. 1).
17. Return to blower compartment and locate black and yellow power
wires from heater module; these wires will terminate in plug
connectors that mate with the plug from the heater control installed
in Step 13 above. Snap these connectors into place; dress and secure
wires to fan wires with wire ties provided (See Fig. 9).
18. The factory speed tap for electric heat operation is tap 2. Refer to
blower performance table in the unit installation instructions or
pre-sale literature to determine available airflow at duct system
external static pressure. Compare the actual airflow with the
minimum required airflow from Table 2. If tap 2 airflow is lower
than minimum required airflow, recheck blower performance table
to see if minimum airflow can be achieved on tap 3. If tap 3 airflow
meets the minimum CFM requirement, change speed tap for
electric heat from tap 2 to tap 3 in unit control box. See unit
instructions and wiring diagram. If tap 3 airflow does not achieve
minimum CFM requirement, then another electric heater that meets
the minimum CFM requirement must be used.
19. Reattach the blower access panel.

3. Insert first field power line through the Electrical Panel bottom hole
(see Fig. 12 or Fig. 13) and connect to electric heater as shown in
their respective wiring diagram found on the heater accessory kit.
Electrical heaters with factory installed circuit breakers must have
their field lines connected to the breaker block lugs and electric
heater without factory installed circuit breakers must have their
field lines connected to the heater leads using wire nuts. Ground
electrical equipment in the appropriate locations.
IMPORTANT: Heaters with factory installed circuit breakers may be
installed on a branch circuit protected by either a fuse or circuit breaker.

START-UP
CAUTION
!
ELECTRICAL SHOCK HAZARD
Failure to follow this caution may result in personal injury or death.
Before proceeding, verify that all wiring is correct per factory approved
schematic. Notify equipment supplier immediately of any
discrepancies.
NOTE: Relay, Rectifier and Time Delay Boards
Each heater element is controlled by a 24VDC control relay. Each
control relay is energized by a small rectifier board attached directly to
relay coil terminals. When possible - one rectifier board is used to
control a second relay.
The rectifier board converts incoming 24v AC control signal to DC.
Some heaters may have up to four relays. The second and/or third relay
rectifier board may also have a time delay feature and a small jumper
wire built into it. With the jumper uncut, the time delay is approximately
5 sec after the initial first stage. When jumper is cut at factory, this
provides an 8 sec delay.
1. Refer to base unit installation instructions as required.
2. Check for loose terminal connections.
3. Check that all fuse and circuit breaker short circuit interrupting ratings are adequate.
4. Turn on unit and heater power.
5. Set thermostat to call for heat.
6. Check operation of heater.
7. Check that airflow across the heater is at or above the minimum recommended CFM requirement (See Table 2).
8. Use of accessory electric heaters that are not tested and approved by
the original equipment manufacturer of the packaged air
conditioner or heat pump is not recommended and will not be
warranted by the original equipment manufacturer. Additionally,
damage caused by such heaters to the equipment will not be
covered under warranty by the original equipment manufacturer.
TROUBLESHOOTING
1. Circuit Breakers-Malfunction will interrupt power to the unit. Check for cause of failure, reset or replace.
2. Limit Switch-Malfunction prevents heating element(s) from being energized. Replace switch if malfunction occurs.
3. Relay-Malfunction will not allow heater to energize. Replace faulty relay. Do not attempt to repair.
