WARNING
ELECTRICAL SHOCK HAZARD DO NOT alter cord or plug, and DO NOT use an extension cord. Personal injury or damage to the unit may result.

Be sure that your outlet matches the appropriate blade configuration of the supplied plug and that it is within reach of the service cord. A hardwire kit is available as an accessory to change cord-connected units to hardwired units. The junction box can be mounted with manufacturer's non-electric subbase accessory.

IMPORTANT: All packaged terminal 265-v units can either be hardwired or cord-connected with accessory kits. Both accessories must be purchased separately through your order correspondent.

ALL UNITS
WIRE SIZE - Use recommended wire size given in Table 1 and install a single branch circuit. All wiring must comply with local and national codes. All units are designed to operate off single branch circuits only.

NOTE: Use copper conductors only.

GROUNDING - For safety and protection, the unit is grounded through the service cord plug or through separate ground wire provided on hardwired units. Be sure that the branch circuit or general purpose outlet is grounded.

Table 1- Suggested Branch Circuit Wire Sizes

VOLTAGE SUPPLY
Check voltage supply at outlet. For satisfactory results, the voltage range must always be within the ranges found on the data information plate (Figure 1).

208/230-v CORD-CONNECTED UNITS - The field-supplied outlet must match the plug and be within reach of the service cord. Refer to Table 2 for proper receptacle and fuse type.

IMPORTANT: The 265-v cord-connected units require an accessory subbase, Part No. SUB-BASE, with a field-installed receptacle

See Table 3 and Figure 4.

LOW-VOLTAGE CONNECTIONS REMOTE CONTROL AND ENERGY MANAGEMENT ACCESSORY
Energy Management Accessory must be ordered separately and field-installed. Low-voltage connections must be made for Energy Management Units.

Remote control units are supplied with a low-voltage terminal board for direct interface with a field-supplied low-voltage, manual changeover thermostat or a programmable thermostat (both are Manufacturer-recommended). When properly wired, the unit operation is controlled by either wall-mounted thermostat.
