120 Control Service
– these models require a 15-amp (minimum) standard general service 120 source. See
below for hookup and appropriate servicing disconnect switch should be field installed external to the main geo
cabinet.
This 120 source is used for the control transformer and outputs 120VAC for both the source and load pumps.
Each pump output is internally fused at 10 amps.
Comment
– if either external pump requires a different voltage or power hookup, use 120V relay coil connected
to the terminal block. The line voltage relay contacts can then apply the voltage required by the pumps being
used at the specific installation site.
Single Compressor Models – 2.5 through 6-ton
Dual Compressor Models – 8 through 12-ton
