All line voltage connections must be made through weatherproof
fittings. All exterior power supply and ground wiring must be in
approved weatherproof conduit Low voltage wiring from the
unit control panel to the thermostat requires coded cable. See
below for ground level and rooftop wiring.

AIRFLOW CONVERSION
Units can easily be converted from horizontal to down-discharge
airflow delivery. In down-discharge or high static installations,
the installer should measure the total external static and review
the blower performance charts before performing the installation.
In some installations it will be necessary to change the blower
speed to provide proper air flow.
Horizontal Air Flow
Remove supply and return duct covers which are attached to
the unit as shown below.

UNIT VOLTAGE
The unit transformer is factory connected for 230V operation.
If the unit is to operate on 208V, reconnect the transformer
primary lead and induced draft blower motor leads as shown
on the unit wiring diagram.
HEAT ANTICIPATOR SETTING
The heat anticipator is to be set by measuring the load
(amperage) at the "R" circuit. Follow the instructions provided
by the thermostat for more details.
