Warns about hazard that CAN cause serious personal injury and
property damage if ignored.
(For cord and plug connected units.) Do not bury cord. Locate
cord to minimize abuse from lawn mowers, hedge trimmers and
other lawn equipment.
(For cord and plug connected units) To reduce the risk of electric
shock, replace damaged cord immediately.
(For cord and plug connected units) Risk of electric shock.
Connect only to a grounding type receptacle protected by a
ground-fault circuit interrupter (GFCI). Contact a qualified
electrician if you cannot verify that the receptacle if protected by
a GFCI.
(For cord and plug connected units) To reduce the risk of electric
shock, do not use an extension cord to connect unit to electric
supply; provide a properly located outlet.

Refer to information on motor nameplate for electrical
service data. If the pump on your system is supplied
with a 3-prong twist lock 115V plug, then the appro-
priate male receptacle should be installed. For systems
with a standard 3-prong 115V plug, we recommend a
grounded receptacle be installed with a built-in Ground
Fault Circuit Interrupter (GFCI). Motors should have
fused disconnect switch or circuit breaker and wire
size large enough for pump horsepower and distance
from power source. Wiring should be done in accor-
dance with applicable codes by a competent electri-
cian.

Setting up your system:

Step 1
Remove filter, pump and base from the carton.
Using (2) 1/4 x 20 bolts and washers, mount pump
to base. The pump mounts using the jack nuts
installed in the base. The pump should be posi-
tioned such that the pump strainer is supported by
the system base.
❖ Note: Some systems are supplied with push-in
grommet nuts for the pump mount. Install these
grommets in the base using the pre-drilled holes
noted. (See Step 1A).
Step 1A
Push the grommet nuts into the pre-drilled holes in
the system base. Use the illustration at the right to
ensure the correct holes are used. Position the
slots in the pump motor base over the grommet
nuts and install the self-tapping screws to secure
the pump to the base.
Remove filter, pump and base from the carton.
Using (2) bolts and washers, mount pump
to base. The pump should be positioned
such that the pump strainer is supported by
the system base.

DIAL VALVE INSTALLATION: Carefully remove all sand
particles from the mounting location, being especially
careful of the bolt holes and O-ring groove. Position the O-
ring in the groove. Place valve on tank and rotate until the
valve inlet (marked “PUMP”) is approximately in line with
the pump outlet opening. Install the hex-head bolts and
tighten uniformly, being careful not to OVERTIGHTEN.
Install pressure gauge, after wrapping brass threads with
4 wraps of teflon tape.
❖ NOTE: Seven position valves are equipped with a sight
glass which must be HANDTIGHT only.
❖ S ith t fl t f t
150 Lbs. of sand. Be sure the
standpipe assembly remains centered
while pouring the sand. Now remove
the standpipe cover and place the
diverter on top of the filter basket.
DIAL VALVE INSTALLATION: Carefully remove all sand
particles from the mounting location, being especially
careful of the O-ring groove. Position the O-ring around
the bottom of the multiport. Place valve on tank and rotate
until the valve inlet (marked “PUMP”) is approximately in
line with the pump outlet opening. Install the V-clamp set
to connect the multiport to the filter body. Install pressure
gauge, after wrapping brass threads with 4 wraps of teflon
tape.
NOTE: Selector Valve is equipped with a sight glass
which must be HANDTIGHT only.
Some pressure gauges come with teflon tape factory
installed.

Setting up your system:
Connect the pre-assembled plumbing connection
from the pump discharge to the valve inlet using
the union nuts on either end of the flexible hose.
IMPORTANT: Ensure the o-rings are in the
adapter groove at each end of the hose. These o-
rings were shipped installed at the factory and
could dislodge during transit.
❖ The adapter o-rings may be supplied in the
system hardware kit.
For 4-way valve: Install threaded adapter into the
pump discharge, tighten handtight plus 1/2 turn.
Now install the other adapter into the dial valve
inlet, tighten in the same manner. Place one hose
clamp over each end of the pump to filter hose,
push hose onto each adapter. Position the clamp
over barbed section of the adapter and tighten
with screw driver until snug.
6
If your system is supplied with a backwash adapter:
Remove threaded adapter and tape from the hardware
kit. Prepare backwash fittings by wrapping threads
with teflon tape in a clockwise rotation, four to eight
wraps is usually sufficient. Install adapter into the
waste port of the filter.
You are now ready to connect the system to your pool (see page 7)
kit. Prepare backwash fittings by wrapping threads
with teflon tape in a clockwise rotation, four to eight
wraps is usually sufficient. Install adapter into the
waste port of the filter.
Prepare pre-assembled plumbing connection by
wrapping the threaded end with teflon tape in a
clockwise rotation, four to eight wraps is usually
sufficient. Connect the pre-assembled plumbing
connection from the pump discharge to the valve
inlet: tighten the threaded adapter end of the
flexible hose into inlet on the multiport labeled
pump handtight plus 1/2 turn; then attach the
union nut end onto the pump discharge.
IMPORTANT: Ensure the o-ring is in the adapter
groove on the pump discharge. This o-ring
was shipped installed at the factory and could
dislodge during transit.
The adapter o-ring may be supplied in the
system hardware kit.

Typical system -to-pool plumbing connection:
7
Install four barbed adapters (B) using teflon tape in the following lacations:

System startup:

10
Press down on the dial valve handle
and rotate to WINTERIZE, release
the handle. This action will allow air
into the tank and prevent excessive
back-flow through the strainer.
Cleaning the pump strainer:
Unscrew and remove the clear strainer
cover.

11
Cleaning the pump strainer:
Replace the clear strainer cover.

Backwashing (cleaning) the filter:
1. Set dial valve to BACKWASH.
2. Start pump.
3. Observe water flow in sight glass and
when clear (usually 2-3 minutes)
stop pump.
4. Set valve to RINSE, run for 20-30
seconds. This action removes any
debris trapped in the filter during
backwash. (7 position valve only).
5. Stop pump.
6. Set valve to FILTER.
7. Start pump, you have now resumed
filtering your pool.
12

Winterizing the filter system:
13
Drain the filter tank by first removing the
drain and then set dial valve to WINTERIZE.
Replace the drain cap once filter is drained.
