2. To vacuum, insert hose into skimmer suction manifold
or into vacuum line in pool wall. See instructions pro-
vided by pool builder or pool manufacturer. Start
pump, making sure it is primed and pumping.
3. After vacuuming, clean pump trap to remove accumu-
lated debris, then check filter pressure gage. If reading
is 5 to 7 PSI (34.5 to 48 kPa) higher than initial oper-
ating pressure, backwash filter
Lower or Drain Pool
1. Turn pump ‘OFF’; set valve handle to ‘WASTE’.
2. Use vacuum cleaner hose and head.
3. Start pump; run until pool is lowered to desired level.
4. Turn pump ‘OFF’; set valve handle to ‘FILTER’.
5. Start pump.
STORAGE/
WINTERIZING
Pool chemicals may give off corrosive
fumes. Store chemicals away from system in a well ven-
tilated area.
Explosion hazard. Purging the system with
compressed air can cause components to explode, with
risk of severe injury or death to anyone nearby. Use
only a low pressure (below 5 PSI), high volume blower
when air purging the pump, filter, or piping.
NOTICE: Allowing water to freeze will damage filter and
void warranty. If antifreeze is needed, use propylene glycol;
it’s plastic compatible and non-toxic. Follow manufacturers
instructions. Do not use ethylene glycol based anti-freeze –
it’s toxic and it may damage plastic components.
1. Open all system valves. Set multiport valve at ‘WIN-
TERIZE’ to allow air passage to all ports.
2. Remove drain plug from filter.
3. Drain filter tank completely and replace drain cap
(Figure 12).
4. Gravity drain system as far as possible.
5. Protect areas which retain water with non-toxic
propylene glycol antifreeze (“RV antifreeze”).
6. Cover with plastic or tarpaulin to protect from
weather.
7. Remove drain plugs from pump.
8. Protect from freezing.
Startup for Winterized Equipment:
1. Remove any temporary weather protection placed
around system for shutdown.
2. See “Startup”, Page 8, for reactivation of the filter.
3. Inspect all electrical wiring to pump for damage or
deterioration over the shutdown period. Have a quali-
fied serviceman repair/replace wiring as needed.
Inspect and tighten all watertight connections.
4. Open all valves in suction and return piping.
5. Remove any winterizing plugs in system.
6. Drain all winterizing chemicals (if used) from system;
flush system.
7. Close all drain valves and replace all drain plugs in
system.
8. Fill pool with water to proper level (see pool maufac-
turer’s instructions).
Drain Fitting Installation/Removal
NOTICE: If pool is above height of filter, first close
valves in pump suction and return lines to prevent drain-
ing pool. If there are no shutoff valves installed, discon-
nect suction and return lines and raise ends above pool
water level.
1. Installation: See Figure 12.
2. To Drain Filter:
A. Remove drain cap. Lateral tube should remain in
place inside drain opening to prevent sand from
draining out.
B. Open union coupling on backwash port of Multi-
Port valve. This will allow air into filter and allow
water to drain from filter tank.

Figure 12: Drain Fitting Assembly. This assembly
allows water to drain without losing the sand out of
the filter tank.
Make sure all surfaces are clean and free of sand.
Don’t cross thread cap; don’t overtighten cap.
