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.
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 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.
Motor normally operates at high temperature and will be too
hot to touch. It is protected from heat damage during operation by an automatic internal cutoff switch. Before handling pump or motor, stop motor and
allow it to cool for 20 minutes.
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
NOTICE: This pump is designed to power automatic swimming pool
cleaners or other systems requiring high pressure at relatively low flow
rates. Operating the pump with open discharge or without flow restriction could overload the pump motor. Operate the pump only while connected to the system in which it is designed to operate. When installed
for automatic time clock operation on a swimming pool cleaner system,
be sure that clock is set so that the cleaner booster pump comes on only
when the main circulation system for the pool is operating. Failure to
coordinate the “on” cycles could provide insufficient flow to the cleaner
booster pump, resulting in failure of the booster pump.
INSTALLATION
Only qualified, licensed personnel should install pump and wiring.
Pump mount must:
Be solid - Level - Rigid - Vibration free. (To reduce vibration and pipe
stress, bolt pump to mount.)
Allow pump suction inlet to be as close to pool return line as possible.
Allow use of short, direct suction pipe from tee on return line (See Fig. 1).
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: Use Teflon tape or Plasto-Joint Stik
1
for making all threaded
connections 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.
