IMPORTANT

SAFETY

INSTRUCTIONS

Always follow basic safety pre-

cautions with this equipment, in-

cluding 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 con-

structed 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 disassem-

bled for storage and reassembled

to its original integrity.

INSTRUCTIONS

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 higher than tub suction fitting. (This al-

lows pump to drain completely when tub is drained.)

Have pump suction below tub water level when pump is running.

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 tub

motor compartment.

Piping:

Use flexible or rigid PVC pipe for connections to pump.

Use at least 1-1/2" IPS pipe.

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

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!

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.

Tub fittings must meet International Association of Plumbing and Mechanical

Officials (IAPMO) standards for jetted bathtubs. Use only non-entrapping suc-

tion 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.

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, 50 Hz

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.

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.

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

bonding lug on motor (see Figure 1).

Wiring:

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 spa users. Test GFCI according to manufacturer’s instructions.

Pump must be permanently connected to circuit; be sure no other lights or ap-

pliances are on the same circuit.

Match wire size and circuit breaker size to Table I, Page 6.

Hazardous voltage.

Can shock, burn,

or cause death.

OPERATION

Priming Pump:

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

leakage and flooding! Fill tub to 2 inches (51mm) above top of jets

before starting system.

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 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 tub 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
