7 Wiring Work For personal safety be sure to turn the electrical power OFF at the main entrance (Home Breaker Box) and at the unit control box circuit breakers before attempting any service or maintenance operations. Homeowners WARNING should never attempt to perform any maintenance which requires opening the air handler control box door. his air handler is not equipped with a shield that covers the line voltage electrical supply wires and the circuit breaker connections. ake precautions to prevent accidental electrical shock. Be sure to turn the electrical power OFF at the main entrance (Home Breaker Box) and at the control box circuit breakers before removing the front panel. Power supply wiring with accessory electric heat kit he unit internal wiring is complete except for the power supply and control wires. he use of cable connectors on incoming power supply wires to relieve any strain on wiring is recommended. Follow the steps below to connect the power supply wires. Supply voltage is 08/30V, ø, 60 Hz. Power supply wiring with accessory electric heat kit. Before wiring work, you must turn off all power source.. Indoor unit power should be supplied through the breaker (EL or MC+ELB ) separate from the outdoor power. EL : Earth Leakage Breaker MC : Molded Case Breaker ELB : Earth Leakage Breaker 3. Only copper power cables should be used. 4. Remove the blower and control box access panel (door). 5. Install the cable connectors on the 7/8 diameter holes on Power conduit connection openings the left side of the control box. 6. Connect a wire (minimum 4 AWG) with ring connectors to (L) and (N) terminals located on the right side of the control box that is long enough to reach the other side of the control box as pictured below. 7. Route the power pigtail leads through the control box opening pictured below and route to the left side of the control box for connection to the heat breakers in a later step. VHK-***A_IM ENG_V.4_

8 Wiring Work Power supply wiring with accessory electric heat kit 8. Swing the hinged control plate outward exposing the back side of the control box. Remove the screws holding the electric heat kit block off plate. Save the screws. 9. Carefully pass the accessory heating element through the rectangular opening in the discharge of the air handler and secure the heating element with the screws from step 8. Heating element support rod must be seated in the hole on the opposite side of the discharge. ENGLISH 0. Install the breakers at the front-left of the control box.. Connect the power pigtail leads that are connected to (L) and (N) to the bottom of the breakers.. Insert the power wires through the holes in the casing and through the cable connectors. 3. Strip ½ of the insulation on the end of each power wire. 4. Connect the black supply wire to the high voltage connection lug on the accessory heat kit breaker. 5. Connect the white supply wire to the other high voltage connection lug on the accessory heat kit breaker. 6. Connect the green (ground) wire to the ground lug to the left of the accessory heat kit breakers and tighten the ground lug screw. Make sure to leave extra slack in the ground wire to allow service to the unit without disconnecting the ground wire. If the heat kit requires circuits (dual circuit), both circuit ground wires must be connected to a ground lug (dual circuit kits have two individual ground lugs).

9 Wiring Work Power supply wiring with accessory electric heat kit 7. Connect the six pin male plug on the electric heater assembly to the six pin female plug mounted at the bottom of the control assembly door. 8. Remove the wiring diagram from the accessory heat kit. Remove the paper that covers the adhesive back and place the electric heat wiring diagram over the wiring diagram located on the blower housing. 9. Route temperature sensor from the accessory electric heat kit to the lower section of the AHU cabinet. Attach the sensor to the bottom of the suction pipe as shown below with included wire ties. Suction Pipe Insulation (wrapped around pipe and sensor) Wire ie (to secure sensor to pipe) Suction Pipe Wire ie (to secure insulation) Sensor Sensor Wire 0. Wrap included insulation around the sensor and secure with included wire ties.. Remove the breaker opening cover plate on the AHU door and secure the doors to the unit. NOE: he electric heat kits are equipped with either one or two circuit breakers. hese circuit breakers protect the wiring inside of the AHU in the event of a short circuit. Additionally, these breakers provide a means of disconnecting the power to the unit. he circuit breakers in the AHU's are not meant to protect the branch circuit wiring between the furnace and the building's breaker panel. If sheathed cable is used, refer to NEC National Electrical Code (NFPA 70) or the Canadian Electrical Code, Part I (CSA C.) and local codes for additional requirements concerning supply circuit wiring. Electrical data can be found in ables -5. IMPORAN - All installation on field wiring must be rated at 60ºC or higher. Please refer to the wiring diagrams on the furnace or the tables this manual for more information. he 5kW and 0kW models may be connected to a single or dual branch circuit. Refer to the NEC National Electrical Code (NFPA 70) or the Canadian Electrical Code, Part I (CSA C.) and local codes for wiring material requirements. VHK-***A_IM ENG_V.4_
