Single phase units:
1. Run the high-voltage (L1, L2) and ground leads into the
control box.
2. Connect ground lead to chassis ground connection.
3. Connect L1 to pressure lug connection 11 of the com-
pressor contactor.
4. Connect L2 to pressure lug connection 23 of the com-
pressor contactor.
Three phase units:
1. Run the high-voltage (L1, L2, L3) and ground leads into
the control box.
2. Connect ground lead to chassis ground connection.
3. Locate the black and yellow wires connected to the lines
side of the contactor.
4. Connect field L1 to black wire on connection 11 of the
compressor contactor.
5. Connect field wire L2 to yellow wire on connection 13 of
the compressor contactor.
6. Connect field wire L3 to blue wire from compressor.
B. Special Procedures for 208-v Operation
WARNING:
Make sure that the gas supply then the
power supply to the unit is switched OFF before mak-
ing any wiring changes. Electrical shock can cause per-
sonal injury or death.
C. Control Voltage Connections
NOTE: Do not use any type of power-stealing thermostat. Unit
control problems may result.

*Fuse or HACR Breaker.
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 fuse or HACR breaker. The CGA (Canadian Gas
Association) 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 voltage is
greater than 2%. Use the following formula to determine the percent-
age of voltage imbalance.
% Voltage imbalance
max voltage deviation from average voltage
= 100 x

EXAMPLE: Supply voltage is 460-3-60.
AB = 452 v
BC = 464 v
AC = 455 v

Determine maximum deviation from average voltage.
(AB) 457 − 452 = 5 v
(BC) 464 − 457 = 7 v
(AC) 457 − 455 = 2 v
Maximum deviation is 7 v.
Determine percent of voltage imbalance.

% Voltage Imbalance = 100 x

= 1.53%
This amount of phase imbalance is satisfactory as it is below the maxi-
mum allowable 2%.
IMPORTANT:
If the supply voltage phase imbalance is more than 2%,
contact your local electric utility company immediately.
