Have enough ventilation to maintain air temperature at less than the maximum
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 ade-
quate 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 - Non-combustible. (To reduce
vibration and pipe stress, bolt pump to mount.)
Allow pump suction inlet height to be as close to water level as possible.
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: Use Teflon tape or Plasto-Joint Stik1for making all threaded connec-
tions to the pump. Do not use pipe dope; pipe dope will cause stress cracking
in the pump.
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.

Piping:
Use at least 2" IPS PVC (51mm) pipe. Increase size if a long run is needed.
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.
Never use a suction pipe smaller than pump suction connection.
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.
POOL PUMP SUCTION
REQUIREMENTS
Pump suction is hazardous and can trap and drown or disem-
bowel bathers. Do not use or operate swimming pools, spas, or hot tubs if a
suction outlet cover is missing, broken, or loose. Follow the guidelines below
for a pump installation which minimizes risk to users of pools, spas, and hot
tubs.
Entrapment Protection
The pump suction system must provide protection against the hazard of
suction entrapment or hair entrapment/entanglement.
Suction Outlet Covers
All suction outlet covers must be maintained. They must be replaced if
cracked, broken, or missing.
See below for outlet cover certification requirements.
All suction outlets must have correctly installed, screw-fastened covers in
place.

Testing and Certification
Suction outlet covers must have been tested by a nationally recognized testing
laboratory and found to comply with the latest ASME/ANSI Specification for
Suction Fittings For Use in Swimming Pools, Spas, Hot Tubs, and Whirlpool
Bathtub Applications.
Outlets Per Pump
Provide at least two hydraulically balanced main drains, with covers (see Page
5), for each swimming pool pump suction line. The centers of the main drains
(suction fittings) must be at least three feet apart.
The system must be built so that it cannot operate with the pump drawing
water from only one main drain (that is, there must be at least two main drains
connected to the pump whenever it is running). (See Figure 2). However, if
two main drains run into a single suction line, the single suction line may be
equipped with a valve which will shutoff both main drains from the pump
(see Figure 2).
More than one pump can be connected to a single suction line as long as the
requirements above are met.
Water Velocity
The maximum water velocity through any suction outlet must be 1.5 feet per
second unless the outlet complies with the latest ASME/SNSI Specification for
Suction Fittings For Use in Swimming Pools, Spas, Hot Tubs, and Whirlpool
Bathtub Applications. In any case, do not exceed the suction fittings maxi-
mum designed flow rate.
If 100% of the pump’s flow comes from the main drain system, the maximum
water velocity in the pump suction hydraulic system must be six feet per sec-
ond or less even if one main drain (suction fitting) is completely blocked. The
flow through the remaining main drain(s) must comply with the latest
ASME/ANSI Specification for Suction Fittings For Use in Swimming Pools,
Spas, Hot Tubs, and Whirlpool Bathtub Applications.
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.

7
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 Figure 3); 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 Figure 3) to
reinforcing 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. See Figures 4A and 4B for
wiring connection diagrams. Match wire and circuit breaker sizes to correct
Fusing and Wiring Data Chart (Page 8). If other lights or appliances are also on
the same circuit, be sure to add their amp loads to pump amp load. (If unsure
how to do this or if this is confusing, consult a licensed electrician.) Use the
load circuit breaker as the master on-off switch.
Install a Ground Fault Circuit Interrupter (GFCI) in circuit; it will sense a short-
circuit to ground and disconnect power before it becomes dangerous to pool
users. For size of GFCI required and test procedures for GFCI, see manufac-
turer’s instructions.
In case of power outage, check GFCI for tripping (which will prevent normal
water circulation). Reset if necessary.
NOTICE: If you do not use conduit when wiring motor, be sure to seal wire
opening on end of motor to prevent dirt, bugs, etc., from entering motor.

OPERATION
NEVER run pump dry. Running pump dry may damage seals, causing
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.
4. NEVER tighten or loosen clamp while pump is operating!
If pump is being pressure tested, be sure pressure has been released be-
fore removing trap cover.
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.
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.
NOTICE: Maximum ambient temperature for motor operation must not
exceed maximum ambient temperature rating on motor model plate.
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, remove trap cover handle ring and
trap cover; 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.
Replace trap cover and handle ring on trap; turn handle ring clockwise to
tighten cover.
NOTICE: Tighten trap cover handle ring 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, and that there are no leaks in suction pipe.
See Troubleshooting Guide, Page 13.
Routine Maintenance
The only routine maintenance needed is inspection/cleaning of trap basket.
Debris or trash that collects in basket will choke off water flow through the
pump. Follow instructions below to clean trap:
1. Stop pump, close valves in suction and discharge, and release all pressure
from system before proceeding.
Hazardous suction.
Can trap hair or
body parts, causing
severe injury
or death.
Do not block
suction.

2. Remove trap cover handle ring (turn counterclockwise). If necessary, tap
handles gently with a rubber mallet.
3. Remove strainer basket and clean. Be sure all holes in basket are clear,
flush basket with water and replace in trap with large opening at pipe con-
nection port (between ribs provided). If basket is replaced backwards cover
will not fit on trap body.
4. Clean and inspect lid O-Ring; reinstall on trap.
5. Clean O-Ring groove on trap body and replace cover and handle ring. To
help keep cover from sticking, tighten hand tight only.
6. Prime pump (see priming instructions).
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. Lugs have been provided on the trap lid to use a
lever or pry bar for loosening.
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 drain plugs (Key No. 19, Pages 14 - 18). Clean pump and trap
basket thoroughly; replace trap cover.
NOTICE: Tighten trap cover by hand only (no wrenches)! Use a rubber
mallet only if necessary to remove cover! If pump is not anchored, use cau-
tion not to break attached piping!
5. Be sure motor is kept dry and covered.
Storage/Winterizing:
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 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. Gravity drain system as far as possible.
2. Protect areas which retain water with non-toxic propylene glycol antifreeze
(“RV antifreeze”).
3. Enclose entire system in a weatherproof enclosure.
4. To avoid condensation/corrosion damage, allow ventilation; do not wrap
system in plastic.
5. Use a 40% propylene glycol/60% water solution to protect pump to -50°F
(-46°C).
Hazardous voltage.
Can shock, burn,
or cause death.
Disconnect power
before working
on pump or motor.
