ELECTRCAL SUPPLY WARNNG: To avoid the risk of electric shock, personal injury, or death, disconnect all electrical power to the unit before performing any maintenance or service.

2 ELECTRCAL SUPPLY WARNNG: To avoid the risk of electric shock, personal injury, or death, disconnect all electrical power to the unit before performing any maintenance or service. The unit may have more than one power supply. if the unit was previously installed without electric heat, the existing supply wiring may not be sufficient to handle the increased load. See the unit rating label or Tables thru for minimum circuit ampacities and maximum overcurrent protection ratings. The units with installed electric heat may be supplied by a single circuit or by multiple circuits. Additional accessory kits may be required if single circuit installation and/or circuit breakers are desired. See Table for accessory descriptions and part numbers. nstallation Remove the control box access panel. Locate the 9 pin ( pin for phase kits) heater plug assembly and remove the jumper cap.

Accessories Circuit Options -- The units with electric heat may be wired for single or multiple circuits and may have circuit breakers or terminal blocks. Note: Circuit breakers installed in the unit are for short-circuit protection of the internal wiring and to serve as a unit disconnect. The circuit breakers DO NOT provide overcurrent protection of the supply wiring. Whether or not circuit breakers are used in the units, overcurrent protection must be provided at the branch circuit distribution panel and sized as shown in Tables thru or on the unit rating label and according to the National Electric Code, Canadian Electrical Code and applicable local codes, tn most cases the overcurrent protection specified on the unit rating label is less than the 60 amp rating of the circuit breakers used in the units. This is because the function of the overcurrent protection required at the distribution panel (field supplied) and the unit mounted breakers is different. When circuit breakers are used they must be used on all circuits. Refer to Table or Table 4 for the correct number of circuit breakers to install. See Table for the correct circuit breaker for the application. if the number of circuits as shown in Table or Table 4 is more than one, circuit breakers are required, tf single circuit supply wiring is desired, use the 4-pole single circuit adapter kit (PN 90) when two -pole circuit breakers are used and the 6-pole single circuit adapter kit (PN 96) when three -pole circuit breakers are used. The single circuit adapter kits are not applicable to three phase units. if circuit breakers are not being used, proceed to the Terminal lock section. Circuit reakers -- f circuit breakers are used for any circuit, they must be used for all circuits. Use one breaker for each circuit as shown in Table. reaker Attachment -- nstall the circuit breaker mounting rail to the control panel with the 4 blunt tip screws provided. Attaching to racket- Attach the circuit breakers in the unit by hooking the bottom in the base of the circuit breaker onto the left rail of the bracket and rotating to the right. The circuit breaker should snap into place. nstall the breakers so that the "ON" position is at the right.

The white release tab is located at the base of the breaker under the line side (right) terminals. Single Circuit Kit (single phase only) -- Refer to the instructions included with the single circuit adapter kit for details on how to configure the adapter. nstall the adapter as shown in the instructions in the line side (right) of the breakers. Proceed to the Element nstallation section. Terminal locks -- Approved HHK heater kits are shipped with a terminal block for small package units. For large package units the terminal block(s) supplied with the kits will not be used. The electric heater kits will be wired to the existing factory installed terminal block, tf the number of circuits indicated in Table or Table 4 is two or three, then the circuit breakers must be used; see the Circuit reaker section. Element installation -- Remove the blower access panel. Remove the heater close-off plate(s) in the electric heat panel. When installing single banks of heaters, position them closest to the blower. nstall the heater kit in the opening with the limit control towards the top of the unit if the unit is using the side supply and return duct openings. f the unit is using the downshot supply and return openings, install the heater kit in the opening with the limit towards the bottom of the unit. Make sure that the element support rod is inserted into the support bracket. Refer to Figure. Fasten the heater with the same screws used to secure the close-off plates. Staged Heat -- To stage the heat on the kw or 0 kw Heater Kits the factory set wiring will need to be modified. The orange wire in Pin on the Heat Accessory Plug will be re-routed. See the Typical AC (or HP) Thermostat Connection figure in the HP or AC nstallation nstructions.

WARNNG: The heater will not function properly if the elements are not correctly ELEMENT installed. POWERWRNG Route the main power leads (heavy black and red wires) and the 9 or -pin heat plug through the access hole at the top of the control panel to the circuit breaker or terminal block. Connect the 9 or -pin heat kit plug to the heat accessory plug located in the control box. Refer to the detailed wiring diagrams for connections. Make sure that the connections are secure. Select large package units have additional terminal blocks installed. The power leads from the heater kit should be attached to these terminal blocks. Wires needed to connect from terminal blocks to circuit breakers should be field supplied. The 6 inch leads are provided with the heater kit to connect the circuit breaker(s) to the compressor contactor. Mark the appropriate box on the unit rating plate with an "X" to indicate which heater kit has been installed. HEATNG SUPPORT RACKET Y important: Torque the circuit breaker lugs to 4 in=lbs, ARFLOW The maximum external static pressure (ESP) for the units are listed in Table. The unit is factory shipped with a jumper wire between the heating speed contacts and the cooling speed contacts on the blower relay. f the heating/cooling speed desired is the preset speed, then no modifications are required. f a different heating/cooling speed is desired, remove the blower lead attached to terminal #4 on the relay (leave the jumper wire in place). Cut the wire tie retaining the unused motor speed taps and connect the desired motor tap to terminal #4 on the relay. Refer to Figure for the motor lead color coding. For 460V units, refer to the wiring diagram on the blower motor to select a different blower speed. f a heating speed different from the cooling speed is desired, remove and discard the jumper wire from the blower relay. Cut the wire tie holding the unused speed taps. Connect the desired heating speed tap to pin #6 and the desired cooling speed tap on pin #4 of the blower relay, 0/0V units only. For 460V units only, one fan speed is obtainable for both heating and cooling. t is recommended that the fan be set for high speed operation when using electric auxiliary heat. WARNNG: After making any changes to the blower speed setting, be sure to bundle and insulate any unused speed taps so that they will not contact with cabinet or any uninsulated live parts, CLEARANCE % _ Figure.
