Heat Controller, Inc. WATER-TO-WATER (HWW) SERIES Installation & Operation
Electrical-Line Voltage
All eld installed wiring, including electrical ground, must
comply with the National Electrical Code as well as all ap-
plicable local codes.
Refer to the unit wiring diagrams for fuse sizes and a sche-
matic of the eld connections which must be made by the
installing (or electrical) contractor.
Consult the unit wiring diagram located on the inside of
the compressor access panel to ensure proper electrical
hookup.
All nal electrical connections must be made with a length of
exible conduit to minimize vibration and sound transmission
to the building.
208 Volt Operation
All 208-230 Volt units are factory wired for 208 Volt. The
transformers may be switched to 230V operation as illustrat-
ed on the wiring diagram. By switching the Red (230V) and
