Climate Control Duplex
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.
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.
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
accordance with
state or local codes.
