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. Install pump with at least 2 hydraulically balanced main drains equipped

with correctly installed, screw-fastened, anti-entrapment certified covers.
See Page 4.

4. 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 25 ft. lbs. (3.5 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 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.

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.

UNCRATING AND INSPECTION

Handle with care.
Check items received against packing list to be sure that all equipment has

been received.
Inspect for shipping damage. If found, file claim with carrier immediately.

Cleanup

Clean up all trash and other materials which will interfere with installation
from foundation and surrounding area.

For easy assembly, make sure all threaded joints and mating surfaces are
clean. If necessary, clean with wire brush and solvent.

To reduce danger of explosion and fire, do not use gasoline as a

cleaning solvent.

Remove all foreign material (packing, etc.) from pump and strainer.

INSTALLATION

Only qualified, licensed personnel should install pump and wiring.

Foundation

Foundation must:

Be Solid - Level - Rigid - Vibration free.
Be provided with necessary hold-down bolts, washers, and shims.
Allow pump inlet to be as close to water level as possible.
Use short, direct suction pipe (to reduce friction losses).
Locate pump below pool water level (pump is not self priming).
Allow for shutoff valves in suction and discharge piping.
Have adequate floor drainage to prevent flooding.
Be protected from excess moisture.
Allow adequate access and include suction and discharge (isolation) valves

for servicing pump and piping.

POOL PUMP SUCTION
REQUIREMENTS

Pump suction is hazardous and can trap and drown or disem­bowel bathers. Do not use or allow anyone else to use a pool, spa, or hot tub
unless it has at least two suction outlets to each pump suction line (see
“Outlets Per Pump,” Page 5). 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 Page 5 for outlet cover certification requirements.

All suction outlets must have correctly installed, screw-fastened covers in
place.

Outlets Per Pump

Provide at least two hydraulically balanced main drains, with covers (see
above), 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

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 seven 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 – General

System piping must be at least equal to size of pump connections.
To prevent strain on the pump casing and foundation, pipe and fittings must

be aligned to pump without forcing.
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.
