STATEMENT OF QUALITY

Each HYDRO-TEST unit is checked for defects in workmanship or parts at least seven times before being shipped to you. A
final test and setting insures that your Hydro-Test unit is ready to operate when received by you. All Hydro-Test units are made
from 90 - 100 % American made parts. All units are pre-set at the specifications set forth in these instructions before being
shipped.

YOUR HYDRO-TEST UNIT, AS SHIPPED TO YOU, IS READY TO OPERATE WHEN CONNECTED AS FOLLOWS.

1) Connect inlet water hose to the garden hose swivel
fitting on the inlet side of the unit.

2) Connect the outlet hose to the SAE male fitting, located
on the end of the outlet next to the gage.

3) Plug in the cord to a standard 110 volt receptacle with

sufficient power supply. Power requirements are shown
in the unit specifications above.

CAUTION….CAUTION….CAUTION WHEN USING A PORTABLE GENERATOR:

To start the Hydro-Test unit with no damage to the motor, you must have a minimum of 3 times the listed amperage stated
above. It is recommended a portable AC generator of 5000 watts or larger be used. Be sure the generator is putting out full
power before attempting to start your test unit.

EXTENSION CORDS: When using any extension cord be sure to use a cord with sufficient capacity for the amperage

needed for the test unit being used. It is highly recommended that a 12 Ga. or larger wire size be used.

CAUTION: Before testing check maximum set pressure. New units maximum test pressure has been pre-set as follows.

Model 6334…250 PSI Factory Set Can set relief valve at 0 if gravity feeding or as low as incoming water pressure up to 250 PSI max.
Model 6334-350….300 PSI Factory Set Can set relief valve at 0 if gravity feeding or as low as incoming water pressure up to 350 PSI max.
Model 6334-550… 400 PSI Factory Set Can set relief valve as low as incoming water pressure up to 500 PSI max.
Model 6334-550-1…400 PSI Factory Set Can set relief valve at 0 if gravity feeding or as low as 125 PSI up to 500 PSI max.

SAFETY PRECAUTION: BEFORE USING YOUR HYDRO-TEST UNIT BE SURE YOU KNOW WHAT THE MAXIMUM

SET TEST PRESSURE IS. IF YOU DON’T KNOW THE MAXIMUM SET PRESSURE, FOLLOW THE INSTRUCTIONS
OUTLINED IN TO SET MAXIMUM PRESSURE.

TO SET OR CHECK MAXIMUM PRESSURE:

A) With all hoses connected to the unit, attach a valve to

the outlet end of the outlet hose.

B) Turn water supply to the pump ON.
C) WITH WATER ON AND OUTLET HOSE OPEN turn the

unit on.

D) With the Hydro-test unit running, slowly turn the valve on

the outlet hose off. CAUTION: When turning this
valve off always watch the pressure shown on the
gage. If the pressure shown is greater than the
maximum pressure for your unit open the valve and
reduce the pressure setting of the relief valve. When
the valve is totally off, the pressure shown on the
gage is the maximum PSI your test unit will produce.

TO CHANGE PRESSURE SETTING:

A) Loosen the locknut on the relief valve ( large bronze valve with T handle on top ). This nut is located
just below the T handle on top of the valve.
B) To reduce pressure turn the handle to the left ( counterclockwise ). Note: You may have to open and
then close the outlet valve to show the new maximum pressure. To increase pressure turn T handle
to the right (clockwise).
C) When you reach the desired maximum test pressure tighten the locknut on the relief valve.

LUBRICATION:

Only one item requires regular lubrication. You will see a grease fitting located inside the hole on the end of the cover. Every
100 working hours lubricate with a lithium based grease. If unit has not been used for a month or more it is recommended that
the bearing be greased before use.
