non-Sta-Rite equipment, consult manufacturer.

To reduce the risk of injury, do not permit children to use this

product unless they are closely supervised at all times.

INSTALLATION

Installation and wiring of pump should only be done by qualified, licensed

personnel.

Pump mount must:

Be Solid - Level - Rigid - Vibration free. (To reduce vibration and pipe stress,

bolt pump to mount).

Be installed with pump suction inlet below water level at all times (this allows

pump to prime).

Be installed with pump discharge below water level at all times (to avoid

trapped air in discharge line).

Allow discharge line to be level or slope slightly up to heater, spa, or pool.

Have adequate drainage to prevent flooding.

Be protected from excess moisture.

Allow adequate access for servicing pump and piping.

Ventilation:

Provide adequate ventilation to prevent motor overheating.

For continuous running, motor hot air exhaust must be able to escape motor

compartment.

Piping:

Use flexible or rigid PVC pipe for connections to pump.

Suction/discharge piping gate valves will allow removal for servicing.

Use at least 1-1/2" (48mm) IPS pipe.

Fittings restrict flow; for best efficiency use fewest possible fittings.

Pump will not prime if suction pipe leaks.

Unions are provided. Use as follows for leak-free connections to pump:

1. ’O‘ Ring and sealing surfaces must be clean.

2. Assemble handtight only! (NO WRENCHES!)

3. NO pipe compound or Teflon tape on unions.

4. Bond pipe to unions with PVC cement.

Use PVC cement only in a well ventilated area away from flame;

FOLLOW MANUFACTURER‘S INSTRUCTIONS!

Spa Fittings:

Size and number of jets will have a major effect on jet action.

Typical installations use up to four 7/8" or 3/4" diameter jets or up to seven

1/2" diameter jets.

Spa fittings must meet International Association of Plumbing and Mechanical

Officials (IAPMO) standards. Use only non-entrapping suction fitting or dou-

ble 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.

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 (230 Volt, 50Hz,

single phase only)! Incorrect voltage can cause fire or seriously

damage motor and voids warranty!

Grounding:

Install, ground, and wire motor according to local or National Electrical Code

requirements.

Permanently ground motor; use size and type wire required by code.

Ground connection must be made to green grounding terminal under motor

canopy or access plate (see Figure 1).

Connect motor ground terminal to electrical service ground.

Install and bond pump according to local codes and ordinances; use bonding

lug on motor (see Figure 1). Use solid copper conductor No. 8 AWG (8.4mm2)

or larger.

Wiring:

Pump must be permanently connected to circuit. Table I, Page 6, gives correct

wire and circuit breaker sizes for the pump alone. If other lights or appliances

are also on the same circuit, be sure to add their amp loads to pump amp load

before figuring wire and circuit breaker sizes. (If unsure how to do this or if

this is confusing, consult a licensed electrician.) Use the load circuit breaker

as the master on-off switch.

Install a Ground Fault Circuit Interrupter (GFCI) in circuit; it will sense a short-

circuit to ground and disconnect power before it becomes dangerous to pool

users. For size of GFCI required and test procedures for GFCI, see manufac-

turer’s instruction.

In case of power outage, check GFCI for tripping (which will prevent normal

pump operation). Reset if necessary.

NOTICE: If you do not use conduit when wiring motor, be sure to seal wire

opening on end of motor to prevent dirt, bugs, etc., from entering.

OPERATION

Priming Pump:

NEVER run pump dry! Running pump dry may damage seals, causing

leakage and flooding! Fill pump with water before starting motor.

Do not add chemicals to spa system directly in front of pump suction.

Adding undiluted chemicals may damage pump and voids warranty.

Open gate valves before starting system.

Pump will prime itself when used in flooded suction system.

Be sure to release all air from filter and piping system; see spa/filter owner’s

manual.

On two speed models, low speed is used for filtration and heating; high speed

provides therapy jet action.

Do not block pump suction! To do so with body may cause severe or

fatal injury. Small children using spa must ALWAYS have close adult

supervision!

NOTICE: Do not block jets! To do so may flood area causing damage to

equipment and water damage to surrounding area.

Water:

Keep water level at least two inches above bottom of skimmer opening when

system is not in use. Failure to do so can allow air to enter system, causing

pump to lose its prime.

Keep water temperature at 104°F (40°C) or below.

Age or health conditions may require a lower temperature; consult a physi-

cian for more information.

If in doubt, start at a lower temperature and gradually increase it according to

your experience.

Keep an accurate thermometer in bath; check it before getting in.

Do not use or allow the use of the spa by anyone using alcohol or

drugs. The effects of hot water, alcohol and/or drugs can cause dizzi-

ness and falling, loss of consciousness, or heart attack.

A long bath in hot water may cause hyperthermia (too much heat in

the body) which can be fatal. Some symptoms of hyperthermia are:

• Nausea

• Dizziness

• Fainting

If these symptoms appear while in the spa, GET OUT AT ONCE!

Cool the body at once with cold towels or a cool shower.

Call a doctor if symptoms do not go away.

Hazardous suction.

Can trap hair or

body parts, causing

severe injury

or death.

Do not block

suction.

Too much heat

can cause nausea,

dizziness,

fainting, or death.

Check temperature.

before using tub.

PUMP SERVICE

Pump should only be serviced by qualified personnel.

To avoid dangerous or fatal electrical shock hazard, disconnect power

to motor before working on pump or motor!

No lubrication or regular maintenance are needed.

If shaft seal is damaged, repair as follows:

Removing Old Seal:

1. Disconnect power to pump motor.

2. Drain spa and pump; disconnect unions to allow access to pump.

3. Remove six bolts holding front plate to seal plate; remove front plate.

4. Remove shaft cover or motor canopy; using screwdriver in slot on motor

end of shaft or wrench on flats of shaft extension, hold pump shaft and un-

screw impeller from shaft (turn counterclockwise). Rotating half of seal will

come off with impeller.

5. Carefully remove rotating part of seal from impeller sleeve by pulling and

turning on sealing washer and spring (Figure 2). Do not damage impeller

surface where drive ring seats and seals.

6. Carefully remove four motor throughbolts from seal plate (Figure 3); remove

seal plate and use a screwdriver to tap ceramic seat out from the rear

(Figure 4). Do not damage seal cavity in seal plate.

7. Clean cavity from which seal was removed and clean motor shaft.

Installing New Seal:

1. Ceramic seat must be clean and free of dirt, grease, dust, etc. Wet rubber

cup gasket of ceramic seat with small amount of liquid detergent; press into

cavity firmly and squarely with finger pressure (Figure 5).

2. If ceramic seat will not locate properly, remove it, place face up on bench,

and reclean cavity. Ceramic seat should now locate.

3. Seal must be free of dirt, grease, grit, scratches or chips; be sure impeller

sleeve is clean. Slide seal assembly, rubber drive ring first, onto impeller

sleeve until drive ring bottoms on impeller back shroud.

4. Slip slinger over shaft; remount seal plate. Torque throughbolts to 25 inch-

lbs. (29 cm-kg).

5. Screw impeller onto shaft until it seats against shaft shoulder. Work slinger

over end of impeller sleeve so it rides on sleeve (Figure 6).

6. Remount front plate; using pattern, shown in Figure 7, torque bolts to 30

inch-lbs. (34.5 cm-kg). BE SURE to start with bolt in 3 o’clock position as

shown.

7. Reconnect unions; tighten hand tight only.

STORAGE/WINTERIZING

To prevent damage to components from fumes, store spa chemicals

away from pump and spa. If possible, store chemicals in another room.

Allowing pump to freeze will damage pump and void warranty!

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 or wrap pump with

plastic.

For outdoor/unprotected pump installations:

1. Enclose entire system in a weatherproof enclosure.

2. To avoid corrosion damage, allow ventilation; do not wrap system in

plastic.

Follow spa manufacturer’s directions for storage of spa.

Draining Water

To avoid dangerous or fatal electrical shock hazard, turn OFF power to

motor before draining pump.

NOTICE: Do not use anti-freeze solutions (except propylene glycol)

in your spa system. Most anti-freezes are highly toxic and may dam-

age plastic components in the system. Propylene glycol is non-toxic

and will not damage pump components.

1. Close all valves on suction and return piping.

2. Remove drain plug in bottom of front plate.

3. Drain all piping and storage tanks exposed to freezing temperatures.

4. Be sure no airlocks are holding water in the system.

5. Consult spa and filter owner’s manuals for instructions about draining the

rest of the system.

NOTICE: We recommend a drain plug or valve at the low point of the spa

piping to help drain spa system.

6. Before restarting, replace all plugs and make sure all pipe connections are

tightly sealed.

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/replace wiring as needed.

Inspect and tighten all watertight connections.

4. Open all valves in suction and return piping.

5. Remove all winterizing plugs in spa system.

6. Remove all anti-freeze solutions from system.

7. Close all drain valves and replace all drain plugs in spa system.

8. Fill spa with water to proper level (see spa manufacturer’s instructions).
