SINGLE POINT ELECTRICAL CONNECTION
NOTE: All electrical connections, wire sizes and type of conduitshall meet the National Electric Code (NEC) and state and local
codes (or International Electric Code) as applicable.
NOTE: Use minimum 75°C copper wire only.
1. Make sure all disconnects are still open and tagged out asrequired previously.
2. Mark the main unit nameplate with an "X" for the electricheater size being installed. Refer to the electrical datamarked with an "X" on the nameplate for wire andmaximum over current protection sizing.
3. Connect low voltage wires as shown in unit schematicdiagrams found on the base unit installation instructions.These connections must be made in the 24v barrier
section inside the unit panel (See Fig. 3).
4. Insert field power line through the electrical heater accesspanel hole (see Fig. NO TAG or NO TAG) and connect toelectric heater as shown in their respective wiring diagram.Fused electrical heaters field lines wilt be connected to the
fuse block tugs (see Fig. NO TAG) and non fused electricheater field lines wilt be connected to heater leads usingwire nuts. Ground electrical equipment in the appropriatelocations.
IMPORTANT: Heaters with factory installed fuses may beinstalled on a branch circuit protected by either a fuse or circuitbreaker. For all other heaters, the branch circuit must beprotected by a fuse or circuit breaker supplied by others.
5. Connect stripped wires from heater to compressorcontactor leads using supplied wire nuts according to theirheater wiring diagram.
NOTE: Dress wires with wire ties provided. For fused heaters,use pre-mounted wire tires inside of fuse box cover to secureand strain relieve wires.
6. Separate all wires from incoming power leads.
7. Close electrical access panel.
DUAL POINT HEATER INSTALLATION
NOTE: Complete single point heater installation proceduresbefore completing the follow steps.
1. Open all electrical disconnects and install lockout tagbefore beginning any installation or service work.
2. Remove electric access panel (see Fig. 1), check to makesure there is clearance on the inside of control box above
the existing high voltage knockout. Using a knockoutpunch and die combination, make a 7/8-in. hole on theElectrical Heat access panel for second power circuit (seeFig. 2). A knockout punch and die combination or equi-valent toot is required to make this hole. Other types of drillbits or standard hole saws are not acceptable.
3. Attach warning and rating labels in the selected location(see Fig. 1).
4. Mark the main unit nameplate with an "X" next to theaccessory heater "none". Mark the dual point rating labelinstalled at step 3 with an "X" for the electrical heater sizebeing installed. Refer to the electrical data marked with an"X" on each nameplate for wire and maximum over currentprotection sizing.
5. Remove power line connection from heater to unitcontactor and compressor (see Fig. NO TAG and Fig.NO TAG). These are the stripped end wires black andyellow, with opened ends.

START-UP
ELECTRICALSHOCKHAZARD
Failure to follow this warning could result in personal injuryor death.
Before proceeding, verify that all wiring is correct per factoryapproved schematic. Notify factory immediately of anydiscrepancies.
NOTE: Refer to base unit installation instructions as required.1. Check for loose terminal connections.
2. Check that all fuse and circuit breaker short circuit
interrupting ratings are adequate.
3. Turn on unit and heater power.
4. Set thermostat to call for heat.
5. Check operation of heater.6. Check that airflow across the heater is at or above the
minimum recommended CFM requirement (See unitinstallation instructions). Adjust indoor blower heat speedas required. Check that duct system conforms to staticpressure limits in Table 1.
NOTE: See Table 1 for Non-Export units (with -3, -5 or -6 aselectrical option-see product data).
7. Any modifications or repairs to this equipment withoutwritten permission from the factory will be done at theinstaller's own risk and expense.
TROUBLESHOOTING
1. Fuses - Malfunction wilt interrupt power to the unit. Checkfor cause of failure, replace fuses.
2. Limit Switch - Malfunction prevents heating element(s)from being energized. Replace switch if malfunctionoccurs,
3. Contactor - Malfunction wilt not allow heater to energize.Replace faulty contactor. Do not attempt to replace coil ordress contacts.
