MANUFACTURER'S OPERATING INSTRUCTIONS FOR THE
HP-Series PNEUMATIC HYDROSTATIC TEST PUMPS
FOR WARRANTY INFORMATION CALL: 1-800-245-4777
NOTE: Prior to testing any high pressure line, please check all
connections, hoses, and fittings to assure that they are properly
tightened and in good working order. No frays, tears, or cuts.
REQUIRED: Air Compressor capable of 100 PSI, up to 75 CFM.
CONNECTING THE PUMP:
1. Connect the high pressure hose provided, and an inlet water supply
hose, unit must be fed with a pressurized water source. Position
the Test Pump within 8 feet of the test environment.
2. Connect the airline from the compressor to the inlet fitting on the
combination regulator/air filter.
NOTE: AIR FILTER SHOULD BE DRAINED OF ANY WATER OR DIRT PARTICLES
BEFORE, AND AFTER USE. Drain valve is located on the bottom of
filter body.
3. Check the in-line strainer for dirt and debris clean as necessary.
OPERATING THE PUMP:
1.)Turn on the water.
2.) Open the bleeder valve on the test line to bleed off
excess air. NOTE: this should be done several times during
the test cycle.
3.) Start the compressor.
4.) Once the compressor has reached operating pressure, open the outlet
valve on the air compressor slowly, which will allow the air to
flow to the Test Pump. Note: this outlet valve, or “shut-off
valve” may come standard on your air compressor, however if it does
not, a shut-off valve should be installed on your compressor for
convenience & safety to the operator, prior to the testing process.
5.) Set the inlet air pressure to 100 P.S.I. This will give maximum
operating output pressure. To do this, adjust the air regulator,
(a black knob located on the top of the inlet air filter assembly
on the test pump). Pull up on the black knob and turn clockwise to
increase pressure, or counter-clockwise to decrease pressure. Once
the inlet air pressure is set, push down on the knob to lock it in
place.
6.)Start turning regulator clockwise, pressure will begin building as
soon as air flows. When desired test pressure has been met, close
the outlet needlevalve to isolate test environment. To turn off
pump while testing, turn regulator counter clockwise and decrease
or stop air flow, or disconnect air compressor supply. If a
pressure drop is indicated, check the following:
a. Output hose connection at pump.
b. Output hose connection at test line.
c. Leaking test line or air in the test environment.
If the pressure gauge remains constant, turn off compressor and
monitor gauge for your prescribed test time. When test is
complete, turn off water supply, open the high pressure bleeder
valve located beside the outlet port connection on the unit. Bleed
off the water pressure. Repeat the above steps for multiple lines.
Be sure the air pressure gauge reads zero before disconnecting the
air line from pump.
