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 per-
form all pressure tests.
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.
SAVE THESE
INSTRUCTIONS
3
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/cm2).
• Water Temperature for test must be less than 100oF.
(38oC).
• 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.
Risk of strains or crush injuries from lifting
pump. Pump is heavy; when lifting or moving pump, take
all proper precautions for the weights involved.
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 in-
stalled 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.
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, 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 3), 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/ANSI Specification for Suction
Fittings For Use in Swimming Pools, Spas, Hot Tubs, and
Whirlpool Bathtub Applications. In any case, do not ex-
ceed 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.
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.
ELECTRICAL
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.
Hazardous voltage. Can shock, burn, or kill.
Follow the instructions below when working on pump or
wiring.
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.
Hazardous voltage.
Can shock, burn,
or cause death.
