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.)
Pump requires flooded suction.
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.
NOTICE: When connecting threaded pipe directly to pump, use Teflon tape
or Plasto-Joint Stik1 to seal connections. Do not use pipe dope; pipe dope
causes cracking in some plastics and may damage components in piping sys-
tem.
When connecting pipe to pump with union half, use Teflon tape or Plasto-
Joint Stik between pipe and union adapter. Union collar to pump should be
assembled dry and hand-tight.
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.
NOTICE: Support all piping connected with pump!

Piping:
Use at least 1-1/2" (38mm) pipe with 5” (127mm) trap. Use 2” (51mm) pipe
with 6” (152mm) trap. 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 air-
locking, 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 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.
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 Fig. 2); 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 Fig. 2) to rein-
forcing 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; be sure no other lights or ap-
pliances are on the same circuit. Match wire sizes to Table I (Pg. 5).
NOTICE: To prevent dirt, rain, bugs, etc., from entering motor when not
wiring with conduit, be sure to seal wire opening on end of motor.
Use Ground Fault Circuit Interrupter (GFCI) as master on-off switch; it will
sense a short circuit to ground and disconnect power before it becomes dan-
gerous to pool users. Test according to maker’s instructions.
In case of power outage, check GFCI for tripping (which will prevent normal
water circulation). Reset if necessary.

OPERATION
NOTICE: NEVER run pump dry. Running pump dry may damage seals, caus-
ing 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, release all pressure before 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.
Priming Pump
Release all air from filter and piping system: see 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, unscrew and remove trap cover;
fill trap and pump with water.
Lubricate trap cover “O” Ring with petroleum jelly each time it is removed.
Clean and inspect “O” Ring; reinstall on trap cover.
Replace trap cover on trap; turn clockwise to tighten cover.
NOTICE: Tighten trap cover by hand only (no wrenches)! Use a wrench only
if necessary to remove lid!
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, pump suction is below water level, and that there are no leaks
in suction pipe. See Troubleshooting Guide, Page 11.
Storage/Winterizing:
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.
Hazardous suction.
Can trap hair or
body parts, causing
severe injury
or death.
Do not block
suction.

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. Enclose entire system in a weatherproof enclosure.
2. To avoid condensation/corrosion damage, allow ventilation; do not wrap
system in plastic.
3. Use a 40% propylene glycol/60% water solution to protect pump to -50°F
(-46°C).
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. Use a Sta-Rite U79-11 Lid Wrench to remove trap
covers that have been overtightened or have taken a set and cannot be re-
moved by hand.
3. Cap inlet piping after draining to keep water out of the pipes.
4. To prevent pump from freezing, remove the trap cover and drain the tank
body through the two drain plugs provided. Clean pump thoroughly; re-
place trap cover.
NOTICE: Tighten trap cover by hand only (no wrenches)! Use a wrench
only if necessary to remove cover.
5. Be sure motor is kept dry and covered.
Startup For Winterized Equipment
1. Remove any temporary weather protection placed around system for shut-
down.
2. Follow filter manufacturer’s instructions for reactivation of the filter.
3. Inspect all electrical wiring for damage or deterioration over the shutdown
period. Have a qualified serviceman repair wiring as needed.
4. Inspect and tighten all watertight connections.
5. Open all valves in suction and return piping.
6. Remove any winterizing plugs in piping system.
7. Drain all antifreeze from system.
8. Close all drain valves and replace all drain plugs in piping system.
