General Safety Information Continued
1. Always mount the pump with oil sight tube in the
upright position.
2. The correct type and size of hose are vital to good
performance:
a. Use good quality inlet hose, compatible with
fluids being pumped and with good elasticity
to reduce inlet water hammer or pulsation.
Be sure that the hose is not too rigid but
capable of operating at low vacuums without
collapsing. The diameter of the inlet hose
should be at least that of the pump inlet port
size and preferably one size larger if the inlet
line is longer than approximately 6 feet.
b. Use only approved high pressure hose on
the discharge side of the pump.
3. Most ports are provided with hose barb connections.
Use good quality hose clamps, and tighten securely.
NOTE: Use only pipe, fittings, accessories, hose, etc.
rated for the maximum pressure rating of the pump.
4. See the illustration for typical system hook-up.
The diagram shows necessary components and
accessories and their connections within the
complete system.

15. WARNING: Because of the risk of electrical
shock, all wiring should be done by a qualified
electrician.
WARNING: DO NOT handle a pump or pump
motor with wet hands or when standing on a wet
or damp surface, or while standing in water.
16. Do not operate a gasoline engine in an enclosed area.
Be sure the area is well ventilated.
17. Use only pipe, hose and fittings rated for the
maximum rated pressure of the pump or pressure that
the pressure relief valve is set. Check with a local
supplier for the proper pressure rating. Do not use
used pipe!
18. Do not use these pumps for pumping water or other
liquids for human or animal consumption.
19. Do not pressure feed pump inlet.
1. Be sure the oil is halfway up the clear oil sight tube. If
necessary, fill to the correct level with Hypro Oil
(Part Number 2160-0038). Hypro Oil is a specially
formulated, high-grade, nondetergent, SAE 30 weight
oil designed to prolong pump life.
2. Make sure the suction hose barb is tightly screwed onto
the suction union, and that there are no air leaks on the
inlet side of the pump.
3. Check the charge pressure on the pulsation dampener
before starting the pump. The pressure is checked with
a standard automotive air gauge. The pressure should
be at approximately 20% of your operating spray
pressure.
4. The relief valve bypass port should be connected back
to the liquid tank unrestricted. Do not hook the bypass
line back to the inlet port or inlet hose.
5. Always allow the pump to start under low pressure by
putting the pressure release lever in the pump position.
6. Start the pump and run for approximately one minute at
low pressure. Stop the pump and check the oil level in
sight glass. Oil should be halfway up the sight glass.
Add Hypro Oil (Part Number 2160-0038) if necessary.
7. Return the pressure release lever to the pressure
position and adjust the pump to the desired pressure by
changing the relief valve setting on the control unit,
relief valve, or unloader.
