All field wiring must comply with NEC (U.S.A.) and lo- cal requirements.

Install field wiring as follows:

1.Install conduit through side panel openings.

2.Install power lines to connections as shown in Fig. 8. Wrap connections with electrical tape.

Voltage to compressor terminals during operation must be within voltage range indicated on unit nameplate (also see Table 4). Voltages between phases must be balanced within 2% and the current within 10%. Use the formula shown in Table 4, Note 2, to determine the percent voltage imbalance. Operation on improper line voltage or excessive phase im- balance constitutes abuse and may cause damage to elec- trical components. Such operation would invalidate any ap- plicable Carrier warranty.

ACCESSORY ELECTRIC HEAT — If the system is to be equipped with an accessory electric heater, refer to the 40RMQ008 installation instructions and Tables 5A and 5B.

FIELD CONTROL WIRING — Install a Carrier-approved accessory thermostat assembly according to installation in- structions included with the accessory. Locate thermostat as- sembly on a solid wall in the conditioned space to sense av- erage temperature in accordance with thermostat installation instructions. Carrier-approved thermostat is Part Number HH07AT-171. Subbase is HH93AZ-188.

Route thermostat cable or equivalent single leads of col- ored wire from subbase terminals to low-voltage connec- tions on unit (shown in Fig. 9) as described in Steps 1 through 3 below.

1.Connect thermostat wires to screw terminals of low- voltage connection board.

2.Pass the control wires through the hole provided in the corner post. (See Fig. 10.)

3.Feed wire through the raceway built into the corner post to the 24-v barriers located on the left side of the control box. The raceway provides the required clearance be- tween the high- and low-voltage wiring.

NOTE: 39 VA is available for field-installed accessories. Control power requirement for heat pump outdoor unit is 36 VA (sealed). The factory-supplied control transformer is 75 VA.

NOTE: For wire runs, use the following insulated wire:

LENGTH		INSULATION		SIZE
Ft	M	RATING (C)	AWG		sq mm
0-50	0-15.2	35	18		0.82
50-75	15.2-22.9	35	16		1.30
Over 75	Over 22.9	35	14		2.08

LEGEND

AWG — American Wire Gage

All wire larger than no. 18 AWG (American Wire Gage) cannot be directly connected to the thermostat and will re- quire a junction box and splice at the thermostat.
