CHARGING BY WEIGHT

For a new installation, evacuation of interconnecting tubing and evaporator coil is

adequate; otherwise, evacuate the entire system. Use the factory charge shown in

Table 1 of these instructions or unit data plate. Note that charge value includes

charge volume required for 15 ft. of standard size interconnecting liquid line.

Calculate actual charge required with installed liquid line size and length using:

1/4” O.D. = 0.20 oz./ft.

5/16” O.D. = 0.3 oz./ft.

3/8” O.D. = 0.50 oz./ft.

1/2” O.D. = 1.0 oz./ft.

With an accurate scale (+/– 1 oz.) or volumetric charging device, adjust charge dif-

ference between that shown on the unit data plate and that calculated for the new

system installation. If the entire system has been evacuated, add the total calculat-

ed charge.

NOTE: When the total refrigerant charge volume exceeds 10 pounds, the manufac-

turer recommends installing a crankcase heater and start kit.

FINAL LEAK TESTING

After the unit has been properly evacuated and charged, a leak detector should be

used to detect leaks in the system. All piping within the condensing unit, evaporator,

and interconnecting tubing should be checked for leaks. If a leak is detected, the

refrigerant should be recovered before repairing the leak. The Clean Air Act pro-

hibits releasing refrigerant into the atmosphere.

ELECTRICAL WIRING

Field wiring must comply with the National Electric Code (C.E.C. in Canada) and

any applicable local code.

POWER WIRING

It is important that proper electrical power from a commercial utility is available at

the condensing unit contactor. Voltage ranges for operation are shown in Table 5.

Power wiring must be run in a rain-tight conduit. Conduit must be run through the

connector panel below the access cover (see Figure 1) and attached to the bottom

of the control box.

Connect power wiring to control located in outdoor condensing unit electrical box.

(See wiring diagram attached to unit access panel.)

Check all electrical connections, including factory wiring within the unit and make

sure all connections are tight.

IMPORTANT: DO NOT connect aluminum field wire to the contactor terminals.

GROUNDING

A grounding lug is provided near the control for a ground wire.

WARNING

TURN OFF ELECTRIC POWER AT

THE FUSE BOX OR SERVICE

PANEL BEFORE MAKING ANY

ELECTRICAL CONNECTIONS.

ALSO, THE GROUND CONNEC-

TION MUST BE COMPLETED

BEFORE MAKING LINE VOLTAGE

CONNECTIONS. FAILURE TO DO

SO CAN RESULT IN ELECTRICAL

SHOCK, SEVERE PERSONAL

INJURY OR DEATH.
