HGM Merchandisers
MERCHANDISER ELECTRICAL DATA
Refer to Appendix A of this manual or the
merchandiser’s serial plate for electrical
information.
FIELD WIRING
Field wiring must be sized for component
amperes stamped on the serial plate. Actual
ampere draw may be less than specified.
ELECTRICAL CONNECTIONS
All wiring must be in compliance with NEC
and local codes. All electrical connections
(for
the HGM remote models) are to be made in
the electrical Handy Box located behind the
removable base panel at the right end of the
merchandiser when facing the discharge
honeycomb. The cabinet supply breakers
should be disconnected before removing the
enclosure cover.
ELECTRICAL OUTLET:
Before the merchandiser is connected to any
wall circuit, use a voltmeter to check that the
outlet is within the recommended voltage
limits:
The wall circuit must be dedicated for the
merchandiser. Failure to do so voids the
warranty.
Do not use an extension cord.
Never
plug in more than one merchandiser per
electrical circuit.
• Always use a dedicated circuit with the
amperage stated on the unit.
• Plug into an outlet designed for the plug.
• Do not overload the circuit
• Do not use long or thin extension cords.
Never use adapters.
• If in doubt, call an electrician.
All HGM models are supplied with a power cord
and grounding prong for operation on a 115V
power supply.
REFRIGERATION
(Self Contained Models)
Each self contained model is equipped with
its own condensing unit and control panel
located beneath the display area. The correct
type of refrigerant will be stamped on each
merchandiser’s serial plate. The merchan-
diser refrigeration piping is leak tested. The
unit is charged with refrigerant, and shipped
from the factory with all service valves open.
