6. START UP
1. Never run pump dr y! Running pump dr y may cause damage to
the mechanical seal causing leakage and flooding. Fill the pre-filter
with water before starting motor.
2. Before removing the pre-filter Lid, STOP PUMP, CLOSE GATE
VALVES in suction and discharge pipes.
3. Always STOP THE PUMP before when RELEASE ALL PRESSURE from the pump and the
piping system before proceeding.
4. Never tighten or loosen screw while the pump is in operation.
5. The suction pipe and the suction inlet in the pool must be free from obstruction.
Before start-up, the alignment of the pump should be checked. The tubing should be
inspected to ensure that they are properly fitted and tightened and that they do not
exert pressure or tension on the pump's suction or discharge connection. The pump
should never be operated.
Tighten/untighten the pump Lid by hand only.
7. ROUTINE MAINTENANCE
The pump mechanical seal requires no lubrication and ser vice.
The only routine maintenance needed is the inspection and cleaning of the pre-filter
basket. Debris or trash collected in the basket will choke off the water flow through the
pump. Follow the instructions below in order to clean the pre-filter basket:
Turn off the pump, close the gate valve in suction and discharge, and release all
pressure from the system before proceeding.
For SD pump series, turn the transparent Lid cover follow the arrow on the Lid cover by
opening key provided to release and lock the Lid ring.
For SDUS pump series, place the key for Lid around the transparent Lid cover, hold the
two handles and turn anti clockwise to release the Lid.
Remove the pre-filter basket and cleaning. Make sure all the holes in the basket are
clear, flush the basket with water and replace it in the trap with large opening at the
pipe connection port (between ribs provided). If the basket is replaced backwards, the
cover will not fit on the trap body.
Clean and inspect the Lid's O-ring ring; reinstall on the Lid cover.
Clean the ring groove on the pre-filter body and replace the Lid. To help keep the Lid
from sticking, tighten it by hand only.
Put back the basket in 90 degree orientation of the center line properly.
Fill up the filter body with water and Prime the pump.

1. Clear all piping of construction debris and verify that the piping has passed a proper
pressure test.
2. Check the filter and other equipment for proper installation, verifying all clamps and
connections are properly installed as per the manufacturer's instructions.
3. Open any shut off valves on the suction and discharge lines.
4. Open the filter pressure relief valve and release all pressure from the system.
5. If the pump is located below the water level of the pool, opening the pressure relief
valve will fill the pump with water.
6. If the pump is located above the pool water level, remove the Lid from the pre-filter
and fill with water before starting the pump.
7. Check to see that the Lid O-ring and seat areas are clean and lubricated. Debris in the
sealing area can cause air to leak into the system and make it difficult to prime the
pump.
8. Close/tighten the Lid to make an airtight seal.

10.
Turn on the pump.
If the pump does not prime within 15 minutes. Ensure all instructions to this point
have been followed. Stop the pump! Check for suction leaks and repeat steps (I)
through (VIII).

WINTERIZING
If the air temperature drops below 0°C (35°F), the water in the system can freeze and
cause damage. Freezing damage is not warrantable.
To prevent freezing damage follow the procedures listed below:
1. Shut off electrical power for the pump at the house circuit breaker.
2. Drain the water out of the pump case by removing the two drain plugs from the case.
3. Store the plugs in the pump basket.
4. Cover the motor to protect it from severe rain, snow and ice.
5. If it is possible, store the pump in a dr y location during this time.
6. Do not wrap the motor in plastic. It will cause condensation and rust on the inside of
the motor.
