WARNING – Hazardous Pressure. Pumps, filters, and other equipment components of a swimming pool
filtration systems operate under pressure. Incorrectly installed and/or improperly tested filtration equipment and/or components
may fail resulting in injury and/or property damage.
Plumbing
Use Teflon tape to seal threaded connections on molded plastic components. All plastic fittings must be new or thoroughly cleaned before
use. NOTE: Do NOT use Plumber’s Pipe Dope as it may cause cracking of the plastic components.
When applying Teflon tape to plastic threads, wrap the entire threaded portion of the male fitting with one to two layers of tape. Wind the
tape clockwise as you face the open end of the fitting, beginning at the end of the fitting.
The pump suction and outlet ports have molded-in thread stops. Do NOT attempt to force hose connector fitting past this stop. It is
only necessary to tighten fittings enough to prevent leakage. Tighten fitting by hand and then use a tool to engage fitting an additional 1 ½
turns. Use care when using Teflon tape as friction is reduced considerably; do NOT over-tighten fitting or you may cause damage. If
leaks occur, remove connector, clean off old Teflon tape, re-wrap with one to two additional layers of Teflon tape, and re-install connector
.
Fittings
Fittings restrict flow. For better efficiency, use the fewest possible fittings (but at least two suction outlets). Avoid fittings that could cause
an air trap. Pool and spa fittings MUST conform to the International Association of Plumbing and Mechanical Officials (IAPMO)
standards
.
Electrical
WARNING – Ground motor before connecting to electrical power supply. Failure to ground pump motor
can cause serious or fatal electrical shock hazard.
WARNING – Do NOT ground to a gas supply line.
WARNING – TO AVOID DANGEROUS OR FATAL ELECTRICAL SHOCK, TURN OFF POWER
TO MOTOR BEFORE WORKING ON ELECTRICAL CONNECTIONS.
WARNING – Ground Fault Circuit Interrupter (GFCI) tripping indicates electrical problem. If GFCI trips
and won’t reset, consult electrician to inspect and repair electrical system.
WARNING – Fire Hazard. Match supply voltage to motor nameplate voltage.
Insure that the electrical supply available agrees with the motor’s voltage, phase, and cycle, and that the wire size is
adequate for the H.P. (KW) rating and distance from the power source. NOTE: All electrical wiring MUST be in
conformance with all applicable local codes, regulations, and the National Electrical Code (NEC).

Voltage at motor MUST NOT be more than 10% above or below motor name plate rated voltage, or motor may overheat, causing overload
tripping and reduced 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 in accordance with local and national electrical code requirements.
Permanently ground motor. Use green ground terminal provided under motor canopy or access place; use size and type wire required by
code. Connect motor ground terminal to electrical service ground.
Reference NEC codes for all wiring standards including, but not limited to, grounding, bonding and general wiring procedures.
Use a solid copper conductor, size 8 or larger. Run wire from external bonding lug to reinforcing rod or mesh. Connect a No. 8 AWG (8.4
mm
2
) solid copper bonding wire to the pressure wire connector provided on the motor housing and to all metal parts of swimming pool,
spa, or hot tub, and to all electrical equipment, metal piping (except gas piping), and conduit within 5 ft. (1.5 m) of inside walls of
swimming pool, spa, or hot tub.
