STANDARD REMOTE OUTDOOR TYPE – MODEL DAFC

Unit cabinets are constructed of heavy duty aluminum, thoroughly reinforced with riveted

gussets. Fan outlets provide additional strength to fan panel and assure even air flow for

quiet operation. Mounting legs are constructed of heavy duty aluminum and are shipped with

the unit for field installation.

The condenser coil is constructed of plate type die formed, aluminum fins mechanically

bonded to copper tubes and employ full height, self-spacing collars which completely cover

the tube surface. The coil is pressure and leak tested at 425 PSIG air under warm water,

evacuated, dehydrated, and sealed with caps on connections.

Propeller type fans, carefully matched to the coil, cover a large percentage of the coil face

area providing a uniform air distribution. The direct drive fans have heavy duty gauge alumi-

num blades securely riveted to zinc plated, chromate treated center hubs. All fans are stati-

cally and dynamically balanced before shipment and operate at low tip speeds for minimum

vibration and low sound levels.

The fan motors are heavy duty PSC or three phase motors with permanently lubricated ball

bearings. All motors are thermally protected against burn-out and may be started by a single

contactor. Protective slingers shield the motors from weather damage.

All motors are factory wired with leads terminating in a weather protected junction box lo-

cated on the outside of the unit casing. Fan motors are ___ horsepower, 1075 RPM. The

fan guards are constructed of heavy gauge, close meshed steel wire powder coated for cor-

rosion resistance.
