Electrical Information

Hatco 3CS and FR Model Water Heaters are available for
operation on standard power systems. Check the specification
label for the proper power supply.
All internal electrical connections have been made at the
factory. Refer to the appropriate "Electrical Rating Chart" for
wiring and voltage requirements.
Turn OFF power switch, disconnect unit from power
source, and allow unit to cool before performing any
cleaning, adjustments, or maintenance.
Connect Water Heaters to the same power supply as
indicated on the specification decal only. Connecting units
to an incorrect power supply will void the product warranty
and may damage the equipment.
Hardwired Connections
Conductors from a properly sized fused disconnect switch or
circuit breaker must be wired to the heater in accordance with
local electrical codes.
1. Remove the bottom cover screws and remove the bottom
cover.
2. Locate the heater terminal block inside the unit.
NOTE: 3CS and FR Models rated for 6 and 9 kW (wired for
three phase open delta) can be field converted to single
phase. Refer to the electrical diagram supplied with unit
or contact Hatco for assistance.
3. Bring power leads from a properly sized disconnect switch
or circuit breaker through the knockouts provided on the
unit, and connect to the terminal block.
• Use copper wire only. Tighten connections properly to a
minimum of 40 inch pounds.
NOTE: Refer to "Dimensions" in the SPECIFICATION section
for knockout locations.
NOTE: Due to the rigors of transportation all connections should
be checked for tightness before heater is put into
operation.
4. A grounding lug is provided near the terminal block. An
equipment grounding conductor must be properly connected
to it.
5. Replace and secure bottom cover using previously removed
screws.

All FRC Models are shipped with cords.
ELECTRIC SHOCK HAZARD: Units supplied with an
electrical cord, plug, and receptacle require installation of
receptacle to on-site electrical system. Connection must
