INSTALLATION INSTRUCTIONS

MOUNTING THE UNIT

The wall sleeve is attached to the I-TEC unit from the outside of the building. See Figures 11A & 11B. Refer to wall sleeve Manual 2100-562 supplied with sleeve.

Following are the steps for attaching the I-TEC to the wall sleeve.

1.Lift the unit into place making sure that it is aligned side to side.

2.Push the unit back until the rear panel touches the sleeve gasket.

3.This unit must be level from side to side and from front to back. If adjustments are necessary, shim up under the base rails with sheets of metal or any substance not affected by moisture.

4.Attach the sleeve to the unit using the ten (10) ¾" long self-tapping screws supplied with the sleeve.

5.The exhaust sleeve has three (3) ¾" long screw slots in each side flange. Line these up with the screw engagement holes in the fan panel. Attach using six

(6)¾" long pointed sheet metal screws supplied with the sleeve. Extend the sleeve out until it is flush with the louver grill attachment angles.

6.Lock the sleeve in place using two (2) ½" long pointed sheet metal screws on each side by shooting through the slot into a pre-punched hole.

7.A bottom trim piece is shipped loose for installation beneath the doors. Attach the trim piece to the unit with screws provided.

8.The compressor is secured to the base with two

(2)bolts for shipping. Both bolts are identified with a tag. Remove shipping bolts (Figure 5).

WIRING – MAIN POWER

Refer to the unit rating plate and/or Table 2 for wire sizing information and maximum fuse or “HACR Type” circuit breaker size. Each unit is marked with a “Minimum Circuit Ampacity”. This means that the field wiring used must be sized to carry that amount of current. Depending on the installed KW of electric heat, there may be two field power circuits required. If this is the case, the unit serial plate will so indicate. All models are suitable only for connection with copper wire. Each unit and/or wiring diagram will be marked “Use Copper Conductors Only suitable for at least

75°C”. THESE INSTRUCTIONS MUST BE ADHERED TO. Refer to the National Electrical Code (NEC) for complete current carrying capacity data on the various insulation grades of wiring material. All wiring must conform to NEC and all local codes.

The electrical data lists fuse and wire sizes (75°C copper) for all models, including the most commonly used heater sizes. Also shown are the number of field power circuits required for the various models with heaters.

The unit rating plate lists a “Maximum Time Delay Relay Fuse” or “HACR Type” circuit breaker that is to be used with the equipment. The correct size must be used for proper circuit protection, and also to assure that there will be no nuisance tripping due to the momentary high starting current of the compressor motor.

See “START UP” section for information on three phase scroll compressor start-ups.

The field wiring conduit connections are located on the top right-hand corner of the unit with a wire raceway to feed the wires down to the circuit breaker(s). See Figure 12.
