Step 8ÐMake Electrical Connections

To avoid personal injury or death, do not supply power to unit with compressor terminal box cover removed.

Be sure field wiring complies with local and national fire, safety, and electrical codes, and voltage to system is within limits shown on unit rating plate. Contact local power company for correction of improper voltage. See unit rating plate for recommended circuit protection device.

NOTE: Operation of unit on improper line voltage constitutes abuse and could affect unit reliability. See unit rating plate. Do not install unit in system where voltage or phase imbalance (3 phase) may fluctuate above or below permissible limits.

NOTE: Use copper wire only between disconnect switch and unit.

NOTE: Install branch circuit disconnect of adequate size per NEC to handle unit starting current. Locate disconnect within sight from and readily accessible from unit, per Section 440-14 of NEC.

ROUTE GROUND AND POWER WIRES Ð Remove access panel to gain access to unit wiring. Extend wires from disconnect through power wiring hole provided and into unit control box.

The unit cabinet must have an uninterrupted or unbroken ground to minimize personal injury if an electrical fault should occur. The ground may consist of electrical wire or metal conduit when installed in accordance with existing electrical codes. Failure to follow this warning can result in an electric shock, fire, or death.

CONNECT GROUND AND POWER WIRES Ð Connect ground wire to ground connection in control box for safety. Connect power wiring to contactor as shown in Fig. 9.

NOTE: System flow direction must match arrow on bottom of body.

Avoid valve damage while brazing by wrapping valve with a heat-sinking material such as a wet cloth.

3.Braze valve onto end of liquid tube using silver bearing or non-silver bearing brazing material. Consult local code re- quirements.

4.Braze flare adapter onto outlet end of solenoid valve.

Fig. 9ÐLine Power Connections

CONNECT CONTROL WIRING Ð Route 24-v control wires through control wiring grommet and connect leads to control wiring. (See Fig. 10.)

Use No. 18 AWG color-coded, insulated (35°C minimum) wire. If thermostat is located more than 100 ft from unit, as measured along the control voltage wires, use No. 16 AWG color-coded wire to avoid excessive voltage drop.

Use furnace transformer, fan coil transformer, or accessory trans- former for control power, 24-v/40-va minimum.
