THERMOSTAT

The room thermostat should be located on an inside wall approximately 56 inches above the floor where it will not be subject to drafts, sun exposure or heat from electrical fixtures or appliances. Follow manufacturer's instructions enclosed with thermostat for general instal- lation procedure. A minimum of seven color-coded insulated wires (#18 AWG) should be used to connect thermostat to unit.

POWER AND CONTROL WIRING

Field wiring to the unit must conform to provisions of the National Electrical Code, ANSI / NFPA No. 70 (in U.S.A.), current Canadian Electrical Code C22.1 (in Canada) and/or local ordinances. The unit must be electrically grounded in accordance with NEC and CEC (as specified above) and/or local codes. Voltage toler- ances, which must be maintained at the compressor terminals, during starting and running conditions, are indicated on the unit Rating Plate and the Unit Applica- tion Data table.

with a separate branch circuit fed directly from the meter panel and properly fused.

When connecting electrical power and control wiring to the unit, waterproof type connectors MUST BE USED so that water or moisture cannot be drawn into the unit during normal operation. The above waterproofing conditions will also apply when installing a field-supplied disconnect switch.

Refer to the Typical Field Wiring Figure 5 and to the appropriate unit wiring diagram for control circuit and power wiring information.

The internal wiring harness furnished with this unit is an integral part of a CSA design certified unit. Field alteration to comply with electrical codes should not be required.

A fused disconnect switch should be field provided for the unit. The switch must be separate from all other cir- cuits. Wire entry at knockout openings require conduit fittings to comply with NEC (in U.S.A.), CEC (in Can- ada) and/or local codes. Refer to the Dimensions and Clearances Figure 13 for installation location. If any of the wire supplied with the unit must be replaced, replacement wire must be of the type shown on the wir- ing diagram and the same minimum gauge as the replaced wire.

Electrical line must be sized properly to carry the load. Use copper conductors only. Each unit must be wired

TABLE 3: ELECTRIC HEAT APPLICATION DATA

OPTIONAL ELECTRIC HEAT

The factory-installed heaters are wired for single point power supply. Power supply need only be brought into the single point terminal block and thermostat wiring to the low voltage terminal strip located in the upper por- tion of the unit control box.

These CSA approved heaters are located within the central compartment of the unit with the heater ele- ments extending into the supply air chamber. Refer to Figure 13 for access panel location.

Fuses are supplied, where required, by the factory. Some KW sizes require fuses and others do not. Refer to Table 3 for minimum CFM limitations and to Tables 8 and 9 for electrical data.
