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.)
Allow pump suction inlet height to be as close to water level as possible.
Pump will not lift water more than 10'(3m).
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 Stik1to seal connections. Do not use pipe dope; pipe dope
causes cracking in some plastics and may damage components in piping system.
When connecting pipe to pump with union half, use Teflon tape or PlastoJoint 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.

Piping:
Use at least 1-1/2" (38mm) pipe (use 2"(51mm) pipe if possible). Increase size
if a long run is needed. When using 1-1/2" pipe, connect to pump with 1-1/2"
to 2" (38 to 51mm) reducing adapter.
To avoid strains on the pump, support both suction and discharge pipes independently. 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.
To avoid airlocking, 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 nameplate 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 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 reinforcing 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 appliances 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 dangerous 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, causing 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.
If pump is being pressure tested, be sure pressure has been released 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
(see Figure 4); fill trap and pump with water.
NOTICE: 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)!
Pump should prime now. Priming time will depend on vertical length of suction 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 is not trying to lift water more than 10'(3m), and that
there are no leaks in suction pipe. See Troubleshooting Guide, Pages 10 and
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 plastic components in the system.
