OPERATING INSTRUCTIONS:
1. Prime the Pump.
A. From a Pressurized Supply
• Connect a garden hose to the garden hose fitting,
making sure the attachment is snug.
• Attach the high pressure hose to the quick connect on
the pump.
• Without plugging in or turning on the pump, turn on the
supply of water and open the outlet valve.
• Once water begins to flow out of the high-pressure hose
and the air is purged out, close the outlet valve.
B. From a Non-Pressurized Supply
• Connect a garden hose to the garden hose fitting, making
sure the attachment is snug.
• Make sure the hose end is not resting on the bottom or
side of the supply container. This will not allow water to
flow, causing priming and suction problems with
the pump.
• Priming the pump is easier if it is at equal or lower height
of the supply container.
• Attach the high pressure hose to the quick connect on
the pump.
• Plug in the cord and turn on the pump with the air bleed
off (priming valve) open. Water will flow from this valve
once the pump begins to prime.
Note:
A hose can be
attached to the hose barb and run back to the water
supply if desired.
• Close the air bleed-off valve and the pump will quickly
prime. Make sure the outlet valve is open.
• Once water begins to flow out of the high-pressure hose
and the air is purged out, close the outlet valve and turn
off the pump.
Priming Tips:
A. When priming the pump from a non-pressurized supply,
it is recommended to fill the input garden hose before
turning on the pump.
B. The input fitting for the pump is a standard garden hose
connection. When this attachment is made it is important
to make sure the garden hose is tightened snuggly so that
the pump does not suck air through the lose connection.
A loose connection will make the pump hard to prime.
C. The shorter the garden hose, the easier it is to prime the
pump. Long hoses tend to collapse from the suction of the
pump when drawing from a non-pressurized system,
restricting flow.
D. Use a hose that is rigid enough so that it does not collapse,
especially when drawing water from a non-pressurized
system.
2. Connect the High Pressure Hose to the system being
checked.
A. If the supply water is coming from a pressurized system,
it is recommended to fill the system to be tested with water
prior to turning on the pump. This can be done simply by
opening the Outlet valve on the pump, allowing water to
flow through the pump and high-pressure hose into the
system being tested. Once the system fills and pressure
begins to rise, proceed to the next step.
B. Non-pressurized systems should be filled with water prior to
attaching the high-pressure hose and turning on the pump,
if at all possible. This could speed up the testing process.
C. The output fitting at the end of the high-pressure hose is
3/8” NPT. An adaptor may be used to attach this hose to
the system that is being pressure tested.
3. Plug in the cord and turn on the pump to pressurize the
system to the desired test pressure.
A. Pressure can be adjusted by turning the pressure
adjustment knob on the side of the pump. Turning
clockwise will increase the pressure. Turning counter-
clockwise will decrease the pressure.
4. Once the system reaches the desired pressure, close the
outlet valve and turn off the pump.
A. Once the pump reaches the set pressure it will continue
to run but the water will flow through the Automatic
Bypass and recirculate through the pump. It is not
recommended to run the pump in bypass mode for more
than a couple of minutes. Once the desired pressure is
reached, it is unnecessary to continue running the pump.
Close the valve, turn off the pump and unplug the cord.
B. The pump is equipped with a valve and hose which has a
checkvalve to prevent backflow. The checkvalve only
works when the the hose is detached from the pump.
It is recommended to fill the system being tested through a
valve which can be shut for backflow prevention as well.
