WIRING

NOTE: All wiring should be made in accordance with the National

Electrical Code.

Consult your local Power Company to determine the availability of

sufficient power to operate the unit. Check the voltage, frequency,

and phase at the power supply to ensure it corresponds to the

unit’s RATED VOLTAGE REQUIREMENT.

In accordance with the N.E.C. or local codes, install a branch cir-

cuit fused disconnect near the unit. Determine wire sizes and

overcurrent protection from the unit nameplate ampacity and in

accordance with the Branch Circuit Ampacity table on the next page

or the N.E.C. The wiring should never be sized smaller than is

recommended by either of these two sources.

Fuses smaller than that recommended on the rating plate could

result in unnecessary fuse failure or service calls. The use of

protective devices of larger size than indicated could result in ex-

tensive damage to the equipment. The manufacturer bears no

responsibility for damage caused to equipment as result of the

use of larger than is recommended size protective devices.

All units have undergone a run test prior to packaging for ship-

ment. This equipment has been started at minimum rated voltage

and checked for satisfactory operation. Do not attempt to operate

this unit if the voltage is not within the minimum and maximum

voltages shown on nameplate.

All exterior wiring must be within approved weatherproof conduit.

The unit must be permanently grounded in accordance with local

codes, or in absence of local codes, with N.E.C ANSI/ NFPA NO.

70-1984 or latest edition by using ground lug in the control box.

Fuses or HACR type circuit breakers may be used where codes

permit.

The supply duct from the unit through a wall may be installed

without clearance. However, minimum unit clearances as shown

in the appendix must be maintained. The supply duct should be

provided with an access panel large enough to inspect the air

chamber downstream of the heat exchanger. A cover should be

tightly attached to prevent air leaks.

For duct flange dimensions on the unit refer to the Unit Dimension

illustration in the appendix.

For down-discharge applications, the ductwork should be attached

to the roof curb prior to installing the unit. Duct work dimensions

are shown in the roof curb installation manual.

If desired, supply and return duct connections to the unit may be

made with flexible connections to reduce possible unit operating

sound transmission.

FILTERS

CAUTION

O PREVENT PROPERTY DAMAGE DUE TO FIRE AND LOSS OF

EQUIPMENT EFFICIENCY OR EQUIPMENT DAMAGE DUE TO DUST AND LINT

BUILD UP ON INTERNAL PARTS, NEVER OPERATE UNIT WITHOUT AN AIR

FILTER INSTALLED IN THE RETURN AIR SYSTEM.

Filters are not provided with unit and must be supplied and exter-

nally installed in the return duct system by the installer. An optional

factory approved internal filter rack may also be used. A field-in-

stalled filter grille is recommended for easy and convenient ac-

cess to the filters for periodic inspection and cleaning. When

installing filters, ensure the air flow arrows on the filter are pointing

toward the circulator blower.

Refer to the unit filter size chart below for filter size information.

MINIMUM FILTER SIZE

NOTE: Filters must have adequate face area for the rated quantity

of the unit. See the air delivery table below for recommended filter

size. Size the filters in accordance with their manufacturer recom-

mendations. Throwaway filters must be sized for a maximum face

velocity of 300 feet per minute.
