INITIAL START-UP:
1. Relieve all system pressure and open all air bleeders on total hydraulic system prior to starting the pump. See filter
owner's manual.
2. Ensure that all fittings, clamps, closures and couplings are tight and in accordance with equipment manufacturer's
recommendations.
3. Open suction and discharge valving to allow free flow of water. On flooded suction pumps with strainer pot the
water source is higher than the pump. The water will flow into the pump strainer pot and the pot will fill with water.
On pumps without strainer pot the water will fill the pump housing.
4. On non-flooded suction systems the pot lid clamp will have to be removed by rotating the lid counter-clockwise to
a stop and lifting the clamp.
5. The pump strainer pot should be filled with water up to suction opening on the pump.
6. It is good practice to lubricate the lid o-ring with silicone lubricant each time the lid is removed. The o-ring should
be cleaned and inspected every time the strainer pot is opened.
7. The lid should be replaced on the pot by aligning the clamp ears with the slots on the strainer pot. Press the lid and
clamp down and twist the clamp clockwise to engage.
8. The pump is now ready to prime. Turn the motor on and the pump will prime. The time to prime will depend on the
suction lift and the distance and size of suction piping. Turn off power if the pump does not prime within five minutes
and refer to the Troubleshooting Guide section of this manual.
NOTICE
Never run the pump dry. Running the pump dry may damage the seals and pump housing. This could allow water leakage and
flooding.
SECTION III. PUMP OPERATION AND MAINTENANCE
WARNING
DO NOT open the strainer pot if pump fails to prime or if pump has been operating without water in the strainer pot. Pumps operated
in these circumstances may experience a build up of vapor pressure and may contain scalding hot water. Opening the pump may
cause serious personal injury. In order to avoid the possibility of personal injury, make sure the suction and discharge valves are open
and strainer pot temperature is cool to touch, then open with extreme caution.
The strainer basket in the pump should be inspected and cleaned twice each week. Remove the clear lid and the basket,
and clean debris from basket. Inspect the lid o-ring; if damaged, replace. The pump seal requires no lubrication.
Refer to motor service centers for motor servicing.
SECTION IV. DISASSEMBLY/ASSEMBLY PROCEDURE FOR SEAL REPLACEMENT
WARNING
Never work on pump while it is running or power is still connected. Hazardous voltage can cause severe or fatal injury.
1. Stop pump and relieve system pressure.
2. Disconnect motor power at Circuit Breaker.
3. Close suction and discharge valves.
