Immediately upon detection of gas odor,
retighten the union. Allow 5 minutes to
elapse, then light unit.

b. Make sure that condenser-fan blade is correctly posi-

tioned in fan orifice. Leading edge of condenser-fan
blade should be 1/2 in. maximum from fan orifice
venturi.

c. Ensure fan hub is 1/8 in. maximum from motor housing

(See Fig. 12).

d. Make sure that air filter(s) is in place.

e. Make sure that condensate drain trap is filled with water

to ensure proper drainage.

f. Make sure that all tools and miscellaneous loose parts

have been removed.

CHECK FOR REFRIGERANT LEAKS

Proceed as follows to locate and repair a refrigerant leak and to
charge the unit:

1. Locate leak and make sure that refrigerant system pressure

has been relieved and reclaimed from both high- and
low-pressure ports.

NOTES:
1. In compliance with NEC (National Electrical Code) requirements

for multimotor and combination load equipment (refer to NEC
Articles 430 and 440), the overcurrent protective device for the
unit shall be Power Supply fuse . Canadian units may be
fuse or circuit breaker.

2. Minimum wire size is based on 60 C copper wire. If other than

60 C wire is used, or if length exceeds wire length in table,
determine size from NEC.

3. Unbalanced 3-Phase Supply Voltage

Never operate a motor where a phase imbalance in supply volt-
age is greater than 2%. Use the following formula to determine
the percentage of voltage imbalance.

% Voltage imbalance

max voltage deviation from average voltage

= 100 x

average voltage

EXAMPLE: Supply voltage is 460-3-60.

AB = 452 v
BC = 464 v
AC = 455 v

452 + 464 + 455

Average Voltage =

=

= 457

Determine maximum deviation from average voltage.

(AB) 457
(BC) 464
(AC) 457

Maximum deviation is 7 v.

Determine percent of voltage imbalance.

% Voltage Imbalance = 100 x

457

= 1.53%

This amount of phase imbalance is satisfactory as it is below the
maximum allowable 2%.

IMPORTANT: If the supply voltage phase imbalance is
more than 2%, contact your local electric utility company
immediately.
