GUIDE

Description

These units are completely assembled, piped and wired at the factory

to provide one-piece shipment and rigging. Each unit is pressurized

with a holding charge of Refrigerant R-410A for storage and/or ship-

ping.

The compact design, clean styling, low silhouette, and quiet operation

make these condensing units suitable for almost any outdoor location.

On rooftops . . . because they weigh much less than a single package

unit of similar capacity and are much easier to rig and support. At

ground level . . . because their ample sub-cooling capacity allows them

to be located three or more stories below the evaporator coil.

Every condenser coil is pressurized with air to 325 psig and leak

tested. After assembly, the unit is pressurized with a combination of

Refrigerant R-410A and nitrogen to 450 psig for pressure testing and

additional leak testing. During this pressure test, the operation of the

high pressure control is checked. As the unit is being evacuated and

dehydrated, the operation of the low pressure control is checked.

Every compressor, condenser fan motor, crankcase heater, and elec-

trical control circuit is checked to assure a trouble-free start-up and

years of reliable operation.

The condenser fan guards are vinyl-coated to provide additional rust

protection and to enhance the appearance of the unit.

Compressors are mounted on rubber isolators to reduce the transmis-

sion of vibration. Vertical discharge condenser fans direct sound

upward and away from any surrounding structures.

All sheet metal parts are constructed of commercial grade galvanized

steel. After fabrication, each part is thoroughly cleaned to remove any

grease or dirt from its surfaces. The external parts are coated with a

powder paint to assure a quality finish for many years. This UL

approved coating system has passed the 750-hour, 20% salt spray

test per ASTM Standard B117.

All models include a 1-year limited warranty on the complete unit. An

additional 4-year extended compressor warranty is available as an

option on all models.

A matching line of Evaporator Blower units is also offered to meet your

precise capacity and air handling requirements.
