4.3 INSTALL HYDRAULIC CONNECTIONS
Use only cylinders, tools, hoses and
accessories rated at 10,000 PSI (700kg/cm
2
).
Remove the shipping plugs from the ports to
connect your coupling(s) or hose(s) to manifold.
Use 1.5 wraps of Teflon tape (or suitable thread
sealant) on all threads, leaving the first complete
thread free of tape to ensure no foreign matter
enters the hydraulic circuit.
When making connections with quick
disconnect couplings, make sure the couplings
are fully engaged. Threaded connections such
as fittings, gauges, etc. must be securely
tightened and leak free.
WARNING: Loose or improperly threaded
fittings can be potentially dangerous if
pressurized; however, severe over tightening
can cause premature thread failure. Fittings
need to be tightened secure & leak free. Never
hold or stand directly in line with any
hydraulic connections while pressurizing. Never grab, touch or in any way come in contact with a hydraulic pressure-
leak. Escaping oil can penetrate the skin and a serious injury can result.
#!54)/.
: Do not subject the hose to potential hazards such as sharp surfaces, extreme heat or heavy impact. Do
not allow the hose to kink or twist. Inspect each hose for wear before it is used.
4.4 ELECTRICAL
Check for proper electrical supply before connecting. Be sure the electrical connection is grounded. Check that your
power supply agrees with the motor nameplate and/or Simplex model decal.
NOTE: MOTOR MAY SPARK. DO NOT OPERATE IN AN EXPLOSIVE ATMOSPHERE OR IN THE PRESENCE OF
CONDUCTIVE LIQUIDS.
a. Do not use a power or extension cord that is damaged or has exposed wires.
b. All single phase motors come equipped with a three prong grounding type plug to fit the
proper grounded type electrical outlet. Do not use a two prong ungrounded extension cord
as the pump’s motor must be grounded.
4.5 CONNECTING HYDRAULIC TOOLS OR CYLINDERS
Use only cylinders, tools, hoses and accessories rated at 10,000 PSI (700kg/cm
2
). When making connections with
quick disconnect couplings, make sure the couplings are fully engaged. Threaded connections such as fittings,
gauges, etc. must be securely tightened and leak free. Use 1.5 wraps of Teflon tape (or suitable thread sealant) on all
threads, leaving the first complete thread free of tape to ensure no foreign matter enters the hydraulic circuit.
4.6 PUMP MOUNTING Refer to the chart for mounting dimensions to secure the pump to a fixed surface.
