ELECTRICAL WIRING INFORMATION
– AZ45/AZ65 SERIES
All Zonelines are single-phase 60-hertz units.
For all installations, the feeder, sub-feeder, branch
circuit and electrical protective devices and selection
must conform to the National Electrical Code (NEC)
and to local codes.
Maximum connected load in amperes, including
demands for the electric heater and the fan motor,
are shown on pages 43–44. Branch circuit ampacity
and electrical protective device sizing are shown on
pages 43–44 for 230/208-volt and for 265-volt units.
More than one unit per branch circuit is not
recommended. When in doubt, consult the NEC.
All wiring, including installation of receptacle, must
conform to local electrical regulations and codes.
REPLACEMENT OF EXISTING CHASSIS
230/208 VOLT AND 265 VOLT UNITS
There have been changes to NEC and improvements
and modifications to the Zoneline
®
chassis and sub-
bases since the unit was first introduced. Some of these
changes require alterations to be made when replacing
an older unit with a new chassis.
LINE CORD CONNECTED UNITS
The plug configuration of new line-cord connected
units complies with the current NEC standards. Older
installations may have wall receptacles that conformed to
NEC standards at the time the building was constructed
and may not match the configuration of the plug on the
new line cord. The recommended solution is to change
the wall receptacle to conform to current standard
plug configuration. See chart on this page for current
receptacle configuration.

PERMANENTLY CONNECTED UNITS
WITH SUB BASE
If the existing unit is connected to a sub-base, the
installation of the new unit may involve modifying the
existing installation slightly. It is recommended these
modifications be made by a qualified electrician.
If more assistance is needed, contact the Zoneline
Application Engineer.
