Use refrigerant grade tubing. Service valves are closed from factory and ready for brazing. After wrapping service valve with a wet cloth, braze
sweat connections using industry accepted methods and materials. Consult local code requirements. Refrigerant tubing and indoor coil are now
ready for leak testing. This check should include all field and factory joints.
PROCEDURE 7--MAKE ELECTRICAL CONNECTIONS
WARNING: 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.
A. Route Ground and Power Wires
Remove access panel to gain access to unit wiring. Extend wires from disconnect through power wiring hole provided and into unit control box.
Z_ WARNING: According to NEC, ANSIINFPA 70, and local codes, 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.
B. Connect Ground and Power Wires
Connect ground wire to ground connection in control box for safety. Connect power wiring to contactor as shown in Fig. 3.
