INSTALLATION
Only qualified, licensed personnel should install pump and wiring.
Pump mount must:
Be located away from corrosive or flammable liquids.
Have enough ventilation to maintain air temperature at less than the maxi-
mum ambient temperature rating (Max. Amb.) listed on the motor model
plate. If this pump is installed in an enclosure/pump house, the enclosure
must have adequate ventilation and air circulation to keep the temperature in
the enclosure at or below the motor’s rated ambient temperature whenever
the pump is running.
Be solid - Level - Rigid - Vibration free. (To reduce vibration and pipe stress,
bolt pump to mount.)
Allow pump suction inlet height to be as close to water level as possible.
Pump will not lift water more than 10'(3m).
Allow use of short, direct suction pipe (To reduce friction losses).
Allow for gate valves in suction and discharge piping.
Have adequate floor drainage to prevent flooding.
Be protected from excess moisture.
Allow adequate access for servicing pump and piping.
Fire and burn hazard. Modern motors run at high temperatures.
To reduce the risk of fire, do not allow leaves, debris, or foreign matter to col-
lect around the pump motor. To avoid burns when handling the motor, let it
cool for 20 minutes before trying to work on it.
NOTICE: When connecting threaded pipe directly to pump, use Teflon tape or
Plasto-Joint Stik1to seal connections. Do not use pipe dope; pipe dope causes
cracking in some plastics and may damage components in piping system.
When connecting pipe to pump with union half, use Teflon tape or Plasto-
Joint Stik between pipe and union adapter. Union collar to pump should be
assembled dry and hand-tight.
NOTICE: Pump suction and discharge connections have molded in thread
stops. DO NOT try to screw pipe in beyond these stops.

Teflon Taping Instructions:
Use only new or clean PVC pipe fittings.
Wrap male pipe threads with one to two layers of Teflon tape. Cover entire
threaded portion of pipe.
Do not overtighten or tighten past thread stop in pump port!
If leaks occur, remove pipe, clean off old tape, rewrap with one to two addi-
tional layers of tape and remake the connection.
NOTICE: Support all piping connected with pump!
Piping:
Use at least 1-1/2" (38mm) pipe (use 2"(51mm) pipe if possible). Increase size
if a long run is needed. When using 1-1/2" pipe, connect to pump with 1-1/2"
to 2" (38 to 51mm) reducing adapter.
To avoid strains on the pump, support both suction and discharge pipes inde-
pendently. Place these supports near the pump.
To avoid a strain left by a gap at the last connection, start all piping at the
pump and run pipe away from the pump.
To avoid airlocking, slope suction pipe slightly upward toward the pump.
NOTICE: To prevent flooding when removing pump for service, all flooded
suction systems must have gate valves in suction and discharge pipes.
Fittings:
Fittings restrict flow; for best efficiency use fewest possible fittings.
Avoid fittings which could cause an air trap.
Pool fittings must conform to International Association of Plumbing and
Mechanical Officials (IAPMO) standards.
Use only non-entrapping suction fitting or double suction.

ELECTRICAL
Ground motor before connecting to electrical power supply. Failure to
ground motor can cause severe or fatal electrical shock hazard.
Do not ground to a gas supply line.
To avoid dangerous or fatal electrical shock, turn OFF power to motor
before working on electrical connections.
Ground Fault Circuit Interrupter (GFCI) tripping indicates an electrical
problem. If GFCI trips and will not reset, have a qualified electrician
inspect and repair electrical system.
Exactly match supply voltage to nameplate voltage. Incorrect voltage
can cause fire or seriously damage motor and voids warranty. If in
doubt consult a licensed electrician.
Voltage
Voltage at motor must be not more than 10% above or below motor name-
plate rated voltage or motor may overheat, causing overload tripping and re-
duced component life. If voltage is less than 90% or more than 110% of rated
voltage when motor is running at full load, consult power company.
Grounding/Bonding
Install, ground, bond and wire motor according to local or National Electrical
Code requirements.
Permanently ground motor. Use green ground terminal provided under motor
canopy or access plate (See Fig. 2); use size and type wire required by code.
Connect motor ground terminal to electrical service ground.
Bond motor to pool structure. Use a solid copper conductor, size No. 8 AWG
(8.4 sq.mm) or larger. Run wire from external bonding lug (see FIg. 2) to rein-
forcing rod or mesh.
Connect a No. 8 AWG (8.4 sq.mm) solid copper bonding wire to the pressure
wire connector provided on the motor housing and to all metal parts of the
swimming pool, spa, or hot tub and to all electrical equipment, metal piping
or conduit within 5 feet (1.5 m) of the inside walls of swimming pool, spa, or
hot tub.
Wiring
Pump must be permanently connected to circuit; be sure no other lights or ap-
pliances are on the same circuit. Match wire sizes to Table I (Pg. 5).
NOTICE: To prevent dirt, rain, bugs, etc., from entering motor when not
wiring with conduit, be sure to seal wire opening on end of motor.
Use Ground Fault Circuit Interrupter (GFCI) as master on-off switch; it will
sense a short circuit to ground and disconnect power before it becomes dan-
gerous to pool users. Test according to maker’s instructions.
In case of power outage, check GFCI for tripping (which will prevent normal
water circulation). Reset if necessary.

OPERATION
NOTICE: NEVER run pump dry. Running pump dry may damage seals, caus-
ing leakage and flooding. Fill pump with water before starting motor.
Before removing trap cover:
1. STOP PUMP before proceeding.
2. CLOSE GATE VALVES in suction and discharge pipes.
3. RELEASE ALL PRESSURE from pump and piping system.
If pump is being pressure tested, be sure pressure has been released
before removing trap cover.
Fire and burn hazard. Modern motors run at high temperatures.
To reduce the risk of fire, do not allow leaves, debris, or foreign matter to col-
lect around the pump motor. To avoid burns when handling the motor, let it
cool for 20 minutes before trying to work on it. An automatic internal cutoff
switch protects the motor from heat damage during operation.
Do not block pump suction. To do so with body may cause severe or
fatal injury. Small children using pool must ALWAYS have close adult
supervision.
Priming Pump
Release all pressure from filter, pump, and piping system; see the filter
owner’s manual.
In a flooded suction system (water source higher than pump), pump will prime
itself when suction and discharge valves are opened.
If pump is not in a flooded suction system, unscrew and remove trap cover
(see Figure 4); fill trap and pump with water.
Do not lubricate the trap cover O-Ring. The original equipment O-Ring con-
tains a permanent internal lubricant.
NOTICE: If you replace the O-Ring with a non-internally lubricated O-Ring,
you may need to apply a silicone based lubricant.
Clean and inspect “O” Ring; reinstall on trap cover.
Replace trap cover on trap; turn clockwise to tighten cover.
NOTICE: Tighten trap cover by hand only (no wrenches)!
Pump should prime now. Priming time will depend on vertical length of suc-
tion lift and horizontal length of suction piping.
If pump does not prime, make sure that all valves are open, suction pipe end is
under water, pump is not trying to lift water more than 10'(3m), and that there
are no leaks in suction pipe. See Troubleshooting Guide, Pages 10 and 11.
Storage/Winterizing:
NOTICE: Allowing pump to freeze will damage pump and void warranty!
NOTICE: Do not use anti-freeze solutions (except propylene glycol) in your
pool/spa system. Propylene glycol is non-toxic and will not damage plastic
system components; other anti-freezes are highly toxic and may damage plas-
tic components in the system.

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 pump with plastic.
For outdoor/unprotected installations:
1. Enclose entire system in a weatherproof enclosure.
2. To avoid condensation/corrosion damage, allow ventilation; do not wrap
system in plastic.
3. Use a 40% propylene glycol/60% water solution to protect pump to -50°F
(-46°C).
Draining Pump
1. Pump down water level below all inlets to the pool.
To avoid dangerous or fatal electrical shock hazard, turn OFF power to
motor before draining pump.
2. Remove trap cover and use low pressure air to blow accumulated water
from the piping system. Use a pry bar or board to remove trap covers that
have been overtightened or have taken a set and cannot be removed by
hand. Lugs have been provided on the trap lid to use a lever or pry bar for
loosening (see Figure 5).
3. Cap inlet piping after draining to keep water out of the pipes.
4. To prevent pump from freezing, remove trap cover and drain the tank body
through the two drain plugs provided. Clean pump thoroughly; replace trap
cover.
NOTICE: Tighten trap cover by hand only (no wrenches)! If pump is not
anchored, use caution to not break attached piping!
5. Be sure motor is kept dry and covered.
Startup For Winterized Equipment
1. Remove any temporary weather protection placed around system for shut-
down.
2. Follow filter manufacturer’s instructions for reactivation of the filter.
3. Inspect all electrical wiring for damage or deterioration over the shutdown
period. Have a qualified serviceman repair wiring as needed.
4. Inspect and tighten all watertight connections.
5. Open all valves in suction and return piping.
6. Remove any winterizing plugs in piping system.
7. Drain all antifreeze from system.
