Field Connection
Refer to the unit wiring diagram (see back of manual) for electrical connections. When installed, the unit must be electrically grounded in accordance with local codes or in the absence of local codes, with the National Electrical Code, ANSI/NFPA No. 70, and/or the CSA C22.1 Electrical Code, if an external source is utilized.
WARNING
TO AVOID THE RISK OF ELECTRICAL SHOCK, WIRING TO THE UNIT MUST BE POLARIZED AND GROUNDED.
The best protection for the wiring is the lowest rated fuse or circuit breaker which will supply power to the unit during normal operation without nuisance trips. Such a device will provide maximum circuit protection. DO NOT EXCEED THE MAXIMUM OVERCURRENT DEVICE SIZE SHOWN ON UNIT DATA PLATE.
All line voltage connections must be made through weatherproof fittings. All exterior power supply and ground wiring must be in ap- proved weatherproof conduit. Low voltage wiring from the unit con- trol panel to the thermostat requires coded cable.
FLEXIBLE WIRING SETUP
Line and low voltage wiring must enter the unit as shown.

For knockout locations, see dimension drawing in the Product Data Book applicable to your model* . Use the Single Point wiring kit to add further flexibility to the installation wiring.
UNIT VOLTAGE
The unit transformer is factory connected for 230V operation. If the unit is to operate on 208V, reconnect the transformer primary lead as shown on the unit wiring diagram.
AIR CIRCULATION AND FILTERS
DOWNSHOT AIRFLOW CONVERSION
Units are shipped from the factory ready for horizontal airflow. These units can be easily converted from horizontal to downshot airflow delivery. If conversion to vertical airflow is necessary, proceed as follows:
Blower Rotation
1.Cut insulation around bottom openings and remove panels from the bottom of the unit, saving the screws holding the panels in place.
2.From the rear of the unit, remove the four (4) screws securing the blower assembly in place and loosen the two (2) screws directly below the duct opening.
*NOTE: Please contact your distributor or our website for the applicable product data book referred to in this manual.
