5. Open the system at the lowest point for the initial blow
down (making sure the make up water is equal to the
water being dumped). Continue blow down until the
water leaving the drain runs clear, but not less than 2
hours.
6. Shut down pumps and supplementary heat system.
Reconnect the hoses placing the water-to-refrigerant
heat exchanger in the water circulating system.
Note: Vents should be open when the pumps and
supplementary heat system are shut down.
Field Installed Power Wiring
WARNING
Proper Field Wiring and Grounding
Required!
Failure to follow code could result in death or serious
injury.
All field wiring MUST be performed by qualified
personnel. Improperly installed and grounded field
wiring poses FIRE and ELECTROCUTION hazards. To
avoid these hazards, you MUST follow requirements
for field wiring installation and grounding as
described in NEC and your local/state/national
electrical codes.
NOTICE
Use Copper Conductors Only!
Failure to use copper conductors could result in
equipment damage as the equipment was not
designed or qualified to accept other types of
conductors.
Verify that the power supply available is compatible with
the unit’s nameplate. Use only copper conductors to
connect the power supply to the unit.
Main Unit Power Wiring
WARNING
Proper Field Wiring and Grounding
Required!
Failure to follow code could result in death or serious
injury.
All field wiring MUST be performed by qualified
personnel. Improperly installed and grounded field
wiring poses FIRE and ELECTROCUTION hazards. To
avoid these hazards, you MUST follow requirements
for field wiring installation and grounding as
described in NEC and your local/state/national
electrical codes.
A field supplied disconnect switch must be installed at or
near the unit in accordance with the National Electric Code
(NEC latest edition).
Location of the applicable electric service entrance for
HIGH (line voltage) may be found in the Dimensions
section of this manual.
The high-voltage connection is made at the 1K1 contactor
or 1TB power block inside the unit control box (See the
figure below). Refer to the customer connection diagram
that is shipped with the unit for specific termination points.
Provide proper grounding for the unit in accordance with
the local and national codes.

Control Power Transformer
The 24 V control power transformers are to be used only
with the accessories called out in this manual. A 50 VA
transformer is externally fused. Transformers rated greater
than 50 VA are equipped with circuit breakers. If a circuit
breaker trips, turn OFF all power to the unit before
attempting to reset it.
WARNING
Hazardous Voltage!
Failure to disconnect power before servicing could
result in death or serious injury.
Disconnect all electric power, including remote
disconnects before servicing. Follow proper lockout/
tagout procedures to ensure the power can not be
inadvertently energized. Verify that no power is
present with a voltmeter.
The transformer is located in the control panel.
