Bonding Instructions – Permanently wired units will need to
include instructions for connecting the solid copper, equipotential
bonding conductor. For SCUS200, SCUS100, and SCUS150 with ETL
Mark for the United States, the size of the bonding conductor
should be No.8 AWG. For Canada the size of the bonding conductor
should be No. 6 AWG. Bonding Nut location is as photo.
5. START UP
1.Verify the pump shaft turn freely.
2.Check the mains voltage, current and frequency are accordingly
to the name plate.
3.Never run pump dry! Running pump dry may cause damage to
the mechanical seal causing leakage and flooding. Fill the pre-
filter with water before starting motor.
4.Before removing the pre-filter Lid, STOP PUMP, CLOSE GATE VALVES in suction and
discharge pipes.
5.Always STOP THE PUMP before when RELEASE ALL PRESSURE from the pump and the
piping system before proceeding.
6.Never tighten or loosen screw while the pump is in operation.
7.The suction pipe and the suction inlet in the pool must be free from obstruction.
Tighten/untighten the pump Lid by hand only.
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.
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.
9. Turn on the pump.
10. 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 (1)
through (8).
6. ROUTINE MAINTENANCE
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:
1. Turn off the pump, close the gate valve in suction and discharge, and release all
pressure from the system before proceeding.
2. For SC 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 SCUS pump series, place the
key for Lid around the transparent Lid cover, hold the two handles and turn anti
clockwise to release the Lid.
3. 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 back wards, the
cover will not fit on the trap body.
