OPERATION STANDARD SKIMMER
1. Install the weir door in the throat of the skimmer so that the
spring loaded hinge pins pivot freely in the holes in the side of
the throat allowing the weir door to move up and down with the
water level Fig. 12.
2. Remove plugs
3. Install basket
4. Turn pump on and set control valves to desired flow to
skimmer(s)
OPERATION VENTURI SKIMMER
1. Complete steps 1-4 above before proceeding.
2. After running water through return line to clear any construction debris from the line install the dual
pressure nozzle in the venturi return line with the bayonet lugs by inserting and turning ¼ turn. Make
sure the O-ring is in place or you may hear a squeal during operation. The pressure nozzles should
face directly into the return port to the pool when twisted completely to the stop. Open the valve at
the plumbing manifold fully. There is no further adjustment required.
DO NOT GLUE THE DUAL PRESSURE NOZZLE INTO THE
FITTING! This must remain unglued so that it can be removed for
cleaning or replacement and a threaded plug can be threaded into
the bottom port in the event that winterizing is necessary.
NOTICE
3. The venturi skimmer may be operated simultaneously with the normal skimmer functioning or the
suction from the pump may be shut off or not installed allowing only venturi powered skimming
action taking place. Either way, a much stronger skimming action will result when compared to a
standard skimmer. NOTE: THE INSTALLED VALVE CONTROLLING THE SUCTION SHOULD
BE LEFT SLIGHTLY OPEN. THERE ARE OCCASIONS WHEN THE PUMP MAY BE
“STARVED” WHEN 100% OF THE SUCTION IS COMING THROUGH THE MAIN DRAINS
ONLY.
4. If a D.E. Filter is installed one suction line is plumbed to
at least one skimmer in the pool. This line only needs to
be opened when charging the filter with D.E. Note: The
venturi dual pressure nozzle valve must be closed
and off while charging the D.E. or it will be blown
out into the pool.
5. At start up with optional ozone venturi feed line.
Before installing the dual pressure nozzle in the skimmer
venturi return line, insert the short end of the tubing kit
into the side of the dual nozzle assembly. Insert the dual
nozzle into the skimmer then plug the long end of the
tubing kit into the port on the side of the skimmer below
the basket rim. Fig. 13
