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

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 (115 Volt 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.

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.
