be used to prevent excessive line voltage
drop. The additional wire cost is very
small compared with the cost of repair-
ing or replacing a motor electrically
"starved" by the use of supply wires
which are too small.
GROUNDING
Improperly grounded
electrical components
are shock hazards. Make
sure all the components
are properly grounded to prevent
death or serious injury.
This product must be grounded.
Grounding reduces the risk of electrical
shock by providing an escape wire for
the electric current if short circuit
occurs. This product must be installed
and operated with a power cord or
cable that has a grounding wire.
MOTOR HOOKUP AND STARTER
INSTALLATION
Branch circuit protection must be provid-
ed as specified in the United States
National Electrical Code, Chapter 2,
"Wiring Design and Protection." Article
210, using the applicable article "For
Motors and Motor Controllers," (Article
430, Table 430-1 52).
IMPORTANT: Overload protection is
required for all motors. Certain motors
have this protection built-in. To deter-
mine if a motor has built-in overload

protection, refer to the frame size on
the motor nameplate.
Motors with frame size R56HZ, Y56Y or
L143T include built-in overload protec-
tion. No additional protection is
required. Use Figure 2 wiring diagram.
Motors with frame sizes 184T, 215T,
254T or 284T DO NOT have built-in over-
load protection. A magnetic starter is
required. Use Figure 3 wiring diagram.
To change to the alternate voltage
on three phase motors with 230/460
ratings:
1. Rewire motor per data plate on
motor or instruction sheet.
2. Check electric rating of magnetic
starter and replace thermal overload
elements or magnetic starter as
required. The voltage and amperage
ratings are listed on the motor
nameplate.
DIRECTION OF ROTATION
NOTE: Improper rotation will result in
reduced unit life.
The direction of compressor rotation is
defined by facing the flywheel side of
the pump. For models HS2XXX and
HS4XXX, rotation must be clockwise. For
models HS5XXX, the rotation must be
counterclockwise.
The proper direction is very important.
The direction of rotation of 3 phase
motors can be reversed by interchanging
any two motor-line leads. For single phase
motors, refer to the motor nameplate.

Operation
IMPORTANT: Check motor rotation
before operating the compressor.
All lubricated compressor pumps dis-
charge some condensed water and oil
with the compressed air. Install appro-
priate water/oil removal equipment
and controls as necessary for the
intended application.
NOTICE
!
water/oil removal equipment may result
in damage to machinery or workpiece.
GUARDING
The belt guard provided
must be installed before
operating the unit.
All moving parts must be guarded. All
electrical covers must be installed
before turning on the power.
LUBRICATION
Before operating compressor, fill
crankcase with compressor oil accord-
ing to the oil capacity chart listed in
"Replacement Parts Manual."
Some residual oil may still be in the
pump leaving a thin coat on the sight
glass, however; there is not enough oil to
operate the unit. Fill pump with single-
viscosity, ISO100 (SAE 30), non-detergent,
compressor oil (Campbell Hausfeld P/N
ST126700AV). A synthetic oil (SAE 5W30)
