6. START-UP
A
WARNING: NEVER run the pump dry! Running
the pump dry may damage seals, causing leakage and
ooding! Fill the pump with water before starting the
motor. These pumps cannot self-prime.
A
WARNING: Do not block pump suction! To do so
with body may cause severe or fatal injury. Children
using pool must ALWAYS have close adult supervision.
CAUTION: Before removing the lid:
• STOP THE PUMP before proceeding.
• CLOSE THE GATE VALVES in the suction and
discharge pipes.
• RELEASE ALL PRESSURE from the pump and
piping system.
• NEVER tighten or loosen screws while the pump is
in operation.
Priming Pump
1. Release all air from the filter and piping system (see
filter instructions below).
2. In a flooded suction system (water source higher
than the pump) the pump will prime itself when the
suction and discharge valves are opened.
3. If the pump is not in a flooded suction system,
unscrew and remove the trap cover; fill the trap and
pump with water.
4. Clean and inspect the O-Ring; re-install it on the trap
cover.
5. Replace the trap cover on the trap; turn clockwise to
tighten the cover.
NOTE: Tighten the trap cover by hand only. The pump
should prime now. Priming time will depend on vertical
length of suction lift and horizontal length of suction
piping.
Initial Start-Up
NOTE: During initial clean-up of the pool water, it may
be necessary to backwash more frequently due to a
possibly unusually-heavy initial dirt load in the water.
A
WARNING: Always turn the pump o before
changing valve positions. Changing valve positions
while the pump is running can damage the control valve,
which may cause serious injury or property damage.
1. Make sure the correct amount of filter media (specified
sand) is put into the tank and that all connections
have been connected and secured.
2. Depress the multiport valve handle and rotate it
CLOCKWISE (right) to the BACKWASH position.
Always depress the valve handle before turning it to
prevent damage to the multiport valve seal.
3. Prime and start the pump according to the pump
priming instructions above. Make sure all suction and
return lines are open to allow the filter tank to fill with
water.
NOTE: Tighten the trap cover by hand only. Pump should
prime now. Priming time will depend on vertical length of
suction lift and horizontal length of suction piping.
4. Once water is flowing out of the waste line, run the
pump for at least 1 minute. An initial backwash of
the filter is recommended to remove any impurities or
fine sand particles in the sand media.
5. Turn the pump off and set the multiport valve to the
RINSE position. Start the pump and operate it until
the water in the view glass is clear, about 30 seconds
to 1 minute. Turn the pump off and set the valve to
FILTER position and restart the pump. The filter is
now operating in the normal filter mode, filtering dirt
particles from the pool water.
6. Adjust the pool suction and return valves to achieve
the desired flow. Check the system and filter for water
leaks and tighten connections, bolts and nuts, as
required.
d. Connect the pump to the control valve opening
marked PUMP. After connections are made,
tighten the valve flange clamps with the
screwdriver, tapping around the clamp with the
screwdriver handle to help seat the valve flange
clamp.
2. Make the connection from the pool pipe to the control
valve opening marked RETURN, and complete the
other necessary plumbing connections such as the
suction lines to the pump, waste line, etc.
3. Make the electrical connections to the pump, per
pump instructions.
4. To prevent water leakage, make sure all pipe
connections are tight.
Valve Key Assembly
1. Place the valve key so that wedge opening is at TOP
port. See handle in Figure 4. The flat edge of the
cover screw lug should align with the flat edge of the
body screw lug.
2. Position the cover O-rings.
3. Secure the assembly to the body with the cover
screws. Tighten the cover screws evenly and
alternately. Do not over-tighten.
