All units are run through a factory break-in and are tested for air delivery, leakage and power consumption. Units are shipped with a proper fill of compressor oil in the crankcase and are furnished with an intake filter/silencer with a replaceable cartridge. This filter/silencer combination is designed to remove contaminates in the inlet air, as well as provide quieter operation.

All models have conveniently located oil drain and filler ports to facilitate routine maintenance. Tanks have a condensate drain valve with an extension for easy access. Mounting bases are slotted to allow tension adjustments to aid in maintaining proper compressor and motor alignment while adjusting tension.

Mounted and Connected Options

DELUXE ALTERNATOR PACKAGE

All Powerex Duplex air compressors may be ordered with an optional deluxe alternator package consisting of two magnetic motor starts with thermal overloads, an alternating coil, a 120 VAC control transformer and a three- position selector switch. The three- position switch allows for automatic alternation or only running one unit at a time. This will allow for service on one unit while other unit is running. Refer to Table 2 for ordering details and figure 4 for wiring diagram.

BASIC ALTERNATOR PACKAGE

All Powerex duplex air compressors may be ordered with a simplified line voltage basic alternator package. The basic alternator package consists of an alternating coil and two magnetic motor starters. Motor starters are selected and wired for intended input voltage and are furnished with properly sized overload heaters. Refer to Table 2 for ordering details and figure 5 for wiring diagram.

REFRIGERATED AIR DRYER

A factory mounted, Hankinson HPR 5-10 series refrigerated air dryer with automatic condensate drain trap assembly, bypass valve is on all 1/2 through 3 Hp Powerex duplex air compressors. Piping for air dryer is done at the factory. Wiring to power source must be done in the field using integral cord and plug which fits into a standard 120 volt receptacle. Refer to Table 2 for ordering details.

AUTOMATIC TANK DRAIN

Powerex air compressors may be ordered with a manual or electric type automatic tank drain. A manual drain attachment is furnished with each unit. Refer to Table 2 for ordering details. (Order electric drains separately.)

VIBRATION DAMPENING PADS

Waffle type design vibration pads are provided as standard equipment.

Operation

Refer to Installation Data AS/AD-XXX for detailed installation instructions.

Factory calibrated DPST pressure switches provide lead and lag settings. When using an alternator-starter package, the lead switch energizes the alternator and the alternator activates the compressor that was on standby during the previous cycle. If the demand exceeds the capacity of one compressor, the lag switch will cause both compressors to run simultaneously. Upon failure of either compressor, the lag switch will continue to activate the workable compressor.

Single-phase motors have built-in overload protection with automatic reset. Three-phase motors require a manual or magnetic starter and three overload heaters. Heaters are included with three-phase compressors that have a factory mounted alternator.

LUBRICATION

Check lubricating oil level at gauge. Refill if necessary.

Change oil according to maintenance schedule. Before draining oil, remove oil supply cap and loosen oil drain cap to release trapped air. Use Mobil Rarus 427® or Mobil DTE heavy.

Dispose of oil in ! WARNING accordance with

state or local codes.
