• Test caps, test plugs and pressure relief valves available. Consult the current
Dixon Price List (DPL) for part numbers and pricing.
Recommendations
• If an extension cord is needed, the following wire sizes must be used:
25' Cord - not less than 14GA wire
50' Cord - not less than 12GA wire
100' Cord - not less than 10GA wire
Electric damage or personal injury can result from using improperly grounded outlets.
Only a properly grounded 115 Volt outlet accepting three pronged plug should be used.
Serious damage can result from improper or inadequate electric set up. Fuses, wiring
and electrical codes for proper amperage and grounding should be checked.
Make sure that no water / liquid is anywhere that could cause electric shock to the
operator (i.e. on the oor or pump where it could come in contact with electric
connection).

Safety Precautions
• Electric
1. Pump is designed for the testing of rubber hose. We do not recommend it for any
other application.
2. Adequate steps should be taken to protect property and personnel in the event of a failure during a test. These steps should include, but are not limited to the
following:
a) Only trained personnel should conduct hydrostatic testing.b) Use of safety glasses or shields for personnel conducting test and
witnessing test.
c) All personnel should be perpendicular to the test sample and at least
15 feet away.
d) Place test sample in a protective enclosure.e) Restrain both ends of the test sample to prevent hose from whipping in
case of a failure.
f) If testing is done outside of a protective enclosure, restrict the movement
of the couplings by the use of sandbags or other means.
g) Use only water as a test uid.
3. All incidental ttings, intermediate hose and piping should be rated at 3000 psi
minimum.
4. Before removing or adjusting any part of the pumping system or test sample the
following precautions should be exercised:
a) Shut off pump.
b) Shut off water supply.
c) Release pressure inside the test specimen (hose) through bleed valve.

Procedure for Hydrostatic Testing using Electric Test Pump (E.T.P.)
It is very important to know the parameters of the test being conducted. Follow the hose
manufacturer, recommendations of Rubber Manufacturers Association (R.M.A.), OSHA, or
other regulatory bodies guidelines for specic test parameters. The test should be carefully
monitored and all results recorded. Dixon recommends the following
sequence for a successful test:
1. Determine the test pressure of the assembly to be tested.
2. Make sure that the test caps or test plugs and all connections are tight on the test
sample.
3. Connect test specimen (hose) to high pressure outlet intermediate hose. Connection
between test specimen (hose) and intermediate hose should be tight.
4. Connect the bleed-off valve to the other end of the test sample.
5. Open the bleed-off valve on the test sample.
6. Open water inlet valve (1 - see drawing on page 6) to ll test specimen (hose)
7. Fill test sample with water. Vent all air from test sample by keeping the bleed-off valve
elevated until a solid stream of water (no bubbles) is coming out of the bleed-off valve.
8. Close the bleed-off valve at this point. Recommended bleed-off valve 3,000 psi minimum.
9. Turn pressure control knob (2 -see drawing on page 6). Pressure knob located at right hand
side of pump.
10. Start pump (3 - see drawing on page 6). Switch is located on the same side of the pump
as the pressue control knob.
Warning!
Do not turn off water supply once test sample has been lled with water

11. Turn pressure control knob (2 - see drawing on page 6) clockwise until desired test pressure is
shown on liquid lled pressure gauge (5 - see drawing on page 6).
12. Hold test pressure until test duration requirement is met.
13. Turn pressure control knob (2 - see drawing on page 6) off (counter clockwise).
14. Turn off pump (3 - see drawing on page 6). This unit has a manual pressure relief knob (black
knob - 4 - see drawing on page 6) with two lugs that is located on the opposite side of the
pressure control knob. To release pressure turn this knob so that the lugs are in the 12 O'clock
and 6 O'clock positions. To generate pressure the lugs of this knob must be in the 3 O'clock
and 9 O'clock positions.
16. Turn off water inlet valve (1 - see drawing on page 6).
17. Open bleed-off valve to release remaining pressure inside test specimen (hose).
18. Disconnect test sample from intermediate hose.
19. Drain water from test sample.
CAUTION!
When relieving the pressure and draining the test sample, many gallons of water may be
released on the oor or ground. Use all precautions necessary to ensure that no one slips
or falls as a result of this water being on the oor or ground.
