TEST PUMP MODEL TRE-8
FOR WARRANTY INFORMATION CALL [phone].
COMPONENTS:
1. 208-230/460 volt, 3 phase, 10 H.P., TEFC electric motor equipped with
heavy duty switch box.
2. 3600 PSI, 4.3 GPM triplex ceramic plunger pump.
3. Manually operated unloader/bypass valve provides variable pressure
settings up to 3600 PSI MAXIMUM. Bypass is directed back to the
inlet side of the pump.
4. Stainless steel liquid-filled gauge for accurate readings.
5. ¼turn high pressure stainless steel ball valve to isolate output
pressure.
6. High pressure needle valve assembly for bleeding of air and loss
definition.
7. ½” X 8’ high pressure discharge hose.
CONNECTING THE PUMP:
1. Check oil level in pump with dip stick provided. Use detergent
30 wt. oil as needed.
2. Connect a sound ¾” or larger hose to the female hose swivel on the
inlet side of the pump. Pump requires a clean water supply. It is
recommended that the unit be pressure fed. If pump is suction or
gravity fed, the water source should be located as close to the
pump as possible, 6-8 ft. maximum.
3. Connect the high pressure hose supplied to the pump and the line to
be tested. One end has a swivel fitting for easy hook-up. The
line to be tested should already be filled with water.
4. Open ¼turn ball valve on outlet side of pump.
5. Slightly open needle valve on outlet side of pump to relieve air
from piping assembly. Close when water flows freely after opening
supply line.
6. We recommend using a GROUND FAULT CIRCUIT INTERRUPTER (G.F.C.I.),
it could save your life.
OPERATING THE PUMP:
1. Open the supply line feeding the pump or insure that suction hose
is below water level in supply tank.
2. Turn motor on by engaging switch on the switch box.

3. The pressure regulator has been preset at the factory for 3600 PSI.
If you wish to change this setting, loosen locknut, turn black
handle clockwise to decrease the output pressure. If adjustments
are necessary the handle should be turned while there is no
pressure indicated on the gauge.
4. Once test pressure has been reached, the motor should be shut off
and the ballvalve closed simultaneously. NEVER LEAVE THE MOTOR
RUNNING WITH THE BALLVALVE CLOSED.
5. Check for any leaks at this time. If no leaks are found but a drop
in pressure is indicated on the gauge, air in the lines is the
probable cause.
REMEMBER THESE CAUTIONS:
1. Check oil level in pump prior to operating.
2. Use a sound ¾” or larger supply hose.
3. Use a clean water supply to feed the pump.
4. NEVER run the pump dry.
5. NEVER close the ball valve while the pump is running.
6. Flush system thoroughly after each use.
7. Protect the pump from freezing in cold climates, use anti-freeze or
some suitable solution.
USING THE EXCLUSIVE RICE ENGINEERED FEATURE TO IDENTIFY LOSS
1. After test pressure is reached stop motor and close ball valve
simultaneously.
2. Note the pressure reading on the gauge. Wait the specified time
and then note any pressure drop.
3. After noting the pressure at the end of the test period open the
ball valve and pressurize the line back up to the original test
pressure.
4. Shut off the motor and close the ball valve again. Now open the
needle valve on the output assembly and draw out enough water to
duplicate the pressure drop experienced during the test. Collect
this water in a container so that it can be measured. By
duplicating the pressure drop you have also duplicated the exact
amount of water lost during the test period.

RECOMMENDED PERIODIC MAINTENANCE PROCEDURE
1. Change the oil in the pump body after the first 50 hours of
operation
thereafter every 250 hours.
INSTALLATION OF RUBBER SHOCK MOUNTS
1. 4 vibration absorbing rubber shock mounts are provided with the
unit. Install these rubber mounts with the hardware provided in
each corner of the base. Holes have been pre-drilled for this
purpose.
