seal plate (Key No. 4, Page 10).
7. Install the slinger (2) on the end of the impeller sleeve.
8. Steps (3) through (7) result in subassembly of seal
plate, diffuser, impeller, seal and slinger (Key Nos. 4,
7, 8, 6, and 2 respectively, Page 10). Attach the sub-
assembly to the motor as follows:
i. Fit impeller sleeve over motor shaft.
ii. Align motor throughbolts with mounting holes in
seal plate (Key No. 4, Page 10).
iii. Insert a screwdriver in a slot at end of motor shaft
to prevent it from turning and screw on impeller
(Key No. 8, Page 10).
iv. Secure the four motor throughbolts making sure
that the seal plate (Key No. 4, Page 10) butts firmly
against the motor endbell.
9. Install the tank body O-Ring (Key No. 5, Page 10) in
the recess in the seal plate (Key No. 4, Page 10).
10. Fit the tank body (Key No. 18, Page 10). Install and
tighten six capscrews (Key No. 3, Page 10).
11. Replace motor canopy. Re-install pump. Re-connect
union couplings and electrical wiring.
STORAGE/
WINTERIZING
To prevent damage to components from fumes,
store pool and spa chemicals away from pump and
spa. If possible, store chemicals in another well-venti-
lated room.
Allowing pump to freeze will damage pump and void
warranty.
Drain all water from pump and piping when expecting
freezing temperatures or when storing pump for a long
time (see instructions below).
Keep motor dry and covered during storage.
To avoid condensation/corrosion problems, do not cover
or wrap pump with plastic.
For outdoor /unprotected pump installations:
1. Enclose entire system in a weatherproof enclosure.
2. To avoid corrosion damage, allow ventilation; do not
wrap system in plastic.
Pump down water level below all inlets to the pool.
Follow pool/spa manufacturer’s directions for storage of
pool or spa.
NOTICE: Do not use anti-freeze solutions (except propy-
lene glycol) in your pool or spa system. Most anti-freezes
are highly toxic and may damage plastic components in
the system. Propylene glycol is non-toxic and will not
damage pump components.
DRAINING PUMP
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 low pressure (below 5 PSI), high volume blower
when air purging the pump, filter, or piping.
Dangerous or fatal electrical shock haz-
ard, turn OFF power to motor before draining pump.
1. Close all valves on suction and return piping.
2. Remove drain plug in bottom of volute.
3. Drain all piping and storage tanks exposed to freezing
temperatures.
A. Gravity drain system as far as possible.
B. Protect areas which retain water with non-toxic
propylene glycol antifreeze (“RV antifreeze”).
4. Be sure no airlocks are holding water in the system.
5. To prevent pump from freezing, remove trap cover
and drain the tank body through the drain plug, Key
No. 12, Page 10). Use a lid wrench to remove trap
covers that have been overtightened or have taken a
set and cannot be removed by hand. Clean pump
thoroughly. Replace trap cover.
6. Before restarting, replace all plugs and make sure all
pipe connections are tightly sealed.
Startup for winterized equipment
1. Remove any temporary weather protection placed
around system for shutdown.
2. Follow filter manufacturer’s instructions for reactiva-
tion of the filter.
3. Inspect all electrical wiring for damage or deteriora-
tion over the shutdown period. Have a qualified ser-
viceman repair/replace wiring as needed. Inspect and
tighten all watertight connections.
4. Open all valves in suction and return piping.
5. Remove all winterizing plugs from system.
6. Remove all anti-freeze solutions from system.
7. Close all drain valves and replace all drain plugs in
system.
8. Prime plug according to instructions on Page 6.
