OPERATION INSTRUCTIONS
1.
Be sure oil is halfway up the clear oil sight tube. If
necessary, fill to correct level with 30 weight non-
detergent motor oil.
2.
Make sure the suction hose barb is tightly screwed onto
the suction union, and that there are no air leaks on the
inlet side of the pump.
3.
Check the charge pressure on the pulsation damper
before starting the pump. The pressure is checked with
a standard automotive air gauge. The pressure should
be at approximately 20% of the maximum operating
pressure with a minimum charge of 10 PSI.
4.
Allow the pump to start under low pressure by removing
restrictions on the outlet of the pump. The restriction on
the pump is removed by rotating the red knob on the
control unit so that the letter A on the knob is in the 12
o'clock position.
5.
Start pump and let run for approximately one minute at
low pressure. Stop pump and check the oil level in sight
glass. Add 30 weight non-detergent oil if necessary.
6.
Adjust pump to desired pressure by changing the relief
valve setting on the control unit, relief valve or unloader.
First back out relief valve adjustment knob to zero. Then
rotate red bypass selector knob so that the letter C is in
the 12 o'clock position. Adjust pressure by rotating relief
valve adjustment knob to desired pressure.
1.
After use, flush pump with clean water.
2.
Change oil and diaphragms every 500 hours. To drain
oil from the pump, remove cap from oil sight tube, turn
pump upside down and rotate the shaft until oil stops
flowing out. To fill pump with oil, slowly pour oil into sight
tube while turning the pump shaft. Turning the pump
shaft purges all the air out of the crankcase. Always
change oil when replacing diaphragms.
3.
For winter storage or if a freezing condition will be
encountered, flush pump with a 50/50 mixture of water
and antifreeze.
