ATTENTION: READ INSTRUCTION CAREFULLY
All electric unit heaters are shipped fully assembled.
Installation includes hanging the unit, mounting the built-in
and remote accessories, wiring of optional control devices,
and electrical wiring to the unit.
To insure proper delivery of the heated air to desired areas,
follow the mounting height and air projection tables include
in these instructions. Follow Fig. 1 & 2 for minimum wall
and ceiling clearances.
The wall and/or ceiling structure must be sufficient to
support the combined weight of the heater and any mount-
ing bracket and accessories.
Be sure power source is deenergized before installing
heater. Check heater voltage and phase listed on heater
date tape on back of unit to make sure they are the same
as the electrical service supplied.
Certain units are convertable from single to three phase
service. Follow instructions noted on the unit wiring dia-
gram for this conversion. Units that carry a dual voltage
rating (HF) require specific wiring changes when converting
from 240 to 208 volt service supplied.
Open the access panel (2 1/4 turn fasteners).
Remove the desired knock-out(s) on back of the heater.
Install any optional accessories following their installation
instructions before mounting unit. Following the correct
unit/accessory wiring diagram, connect the power supply,
electrical ground and accessories to the correct terminals
or termination points using accepted practices.
