READ AND FOLLOW SAFETY
INSTRUCTIONS!

This is the safety alert symbol. When you see this

symbol on your system or in this manual, look for one
of the following signal words and be alert to the potential
for personal injury.

warns about hazards that will cause death,

serious personal injury, or major property damage if ignored.

warns about hazards that can cause death,

serious personal injury, or major property damage if ignored.

warns about hazards that will or can cause

minor personal injury or property damage if ignored.

NOTICE indicates special instructions not related to hazards.
Carefully read and follow all safety instructions in this

manual and on equipment. Keep safety labels in good

condition; replace if missing or damaged.

Incorrectly installed or tested equipment
may fail, causing severe injury or property
damage.

Read and follow instructions in owner's manual when
installing and operating equipment. Have a trained pool
professional perform all pressure tests.

1. Do not connect system to a high pressure or city water

system.

2. Use equipment only in a pool or spa installation.

3. Trapped air in system can cause explosion. BE SURE

all air is out of system before operating or testing
equipment.

Before pressure testing, make the following safety checks:

Check all clamps, bolts, lids, and system accessories before
testing.

Release all air in system before testing.

Tighten Sta-Rite trap lids to 30 ft. lbs. (4.1 kg-m) torque for
testing.

Water pressure for test must be less than 25 PSI (7.5 kg/cm

2

).

Water Temperature for test must be less than 100° F. (38° C).

Limit test to 24 hours. After test, visually check system to be
sure it is ready for operation. Remove trap lid and retighten
hand tight only.

NOTICE: These parameters apply to Sta-Rite equipment
only. For non-Sta-Rite equipment, consult manufacturer.

IMPORTANT
SAFETY INSTRUCTIONS

Always follow basic safety precautions with this
equipment, including the following.

To reduce the risk of injury, do not per­mit children to use this product unless they are closely
supervised at all times.

This pump is for use with permanently
installed pools and may also be used with hot tubs and
spas if so marked. Do not use with storable pools. A
permanently installed pool is constructed in or on the
ground or in a building such that it cannot be readily
disassembled for storage. A storable pool is con­structed so that it may be readily disassembled for stor­age and reassembled to its original integrity.

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 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
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.

Allow use of short, direction 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.

NOTICE: Support all piping connected with pump!

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 collect around the pump
motor. To avoid burns when handling the motor, let it cool
for 20 minutes before trying to work on it.

Piping:

Use at least 1-1/2" IPS PVC pipe with 5" trap. Use at least
2" pipe with 6" trap. Increase size if a long run is needed.

To avoid strains on the pump, support both suction and
discharge pipes independently. 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 disembowel 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, screw­fastened 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.

4

Outlets Per Pump

Provide at least two hydraulically balanced main drains,
with covers (see below), 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 1). 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 1).

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 maximum 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 second 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

Hazardous voltage. Can shock, burn or cause

death. Ground pump before connecting to power supply.

Ground motor before connecting to electrical
power supply! Failure to ground pump motor can

cause serious 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 nameplate rated voltage or motor may over­heat, causing overload tripping and reduced 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.
