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.)
Pump requiresflooded suction.
Allow use of short, direct suction pipe (To reduce friction losses).
Allow for gate valvesin suction and discharge piping.
Have adequate floor drainage to prevent flooding.
Be protected from excessmoisture.
Allow adequate accessfor servicing pump and piping.
NOTICE: When connecting threaded pipe directly to pump, use Teflon tape
or Plasto-Joint Stik1 to seal connections. Do not usepipe dope; pipe dope
causescracking in someplasticsand may damage componentsin piping sys-
tem.
When connecting pipe to pump with union half, use Teflon tape or Plasto-
Joint Stik between pipe and union adapter. Union collar to pump should be
assembled dry and hand-tight.
NOTICE: Pump suction and discharge connectionshave molded in thread
stops. DO NOT try to screw pipe in beyond these stops.
Teflon TapingInstructions:
Use only new or clean PVC pipe fittings.
Wrap male pipe threadswith one to two layersof Teflon tape. Cover entire
threaded portion of pipe.
Do not overtighten or tighten past thread stop in pump port!
If leaksoccur, remove pipe, clean off old tape, rewrap with one to two addi-
tional layersof tape and remake the connection.
NOTICE: Support all piping connected with pump!

Piping:
Use at least 1-1/2" (38mm) pipe (use 2"(51mm) pipe if possible). Increase size
if a long run isneeded.
To avoid strainson the pump, support both suction and discharge pipesinde-
pendently. Place these supportsnear 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.
NOTICE: To prevent flooding when removing pump for service, all flooded
suction systemsmust have gate valvesin suction and discharge pipes.
Fittings:
Fittingsrestrict flow; for best efficiency usefewest possible fittings.
Avoid fittingswhich could cause an air trap.
Pool fittingsmust conform to International Association of Plumbing and
Mechanical Officials(IAPMO) standards.
Use only non-entrapping suction fitting or double suction.

ELECTRICAL
Ground motor before connectingto electrical power supply. Failure to
ground motor can cause severe or fatal electrical shock hazard.
Do not ground to a gassupply line.
To avoid dangerousor fatal electrical shock, turn OFFpower to motor
before workingon electrical connections.
Ground Fault Circuit Interrupter (GFCI) trippingindicatesan electrical
problem. If GFCI tripsand 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 voidswarranty. If in
doubt consult a licensed electrician.
Voltage
Voltage at motor must be not more than 10% above or below motor name-
plate rated voltage or motor may overheat, causing overload tripping and re-
duced component life. If voltage islessthan 90% or more than 110% of rated
voltage when motor isrunning 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. Usegreen ground terminal provided under motor
canopy or accessplate (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 rein-
forcing 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 partsof 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 wallsof swimming pool, spa, or
hot tub.
Wiring
Pump must be permanently connected to circuit; be sure no other lightsor ap-
pliancesare on the same circuit. Match wire sizesto 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) asmaster on-off switch; it will
sense a short circuit to ground and disconnect power before it becomesdan-
gerousto pool users. Test according to maker’sinstructions.
In case of power outage, check GFCI for tripping (which will prevent normal
water circulation). Reset if necessary.

OPERATION
NOTICE: NEVERrun pump dry. Running pump dry may damage seals, caus-
ing leakage and flooding. Fill pump with water before starting motor.
Before removingtrap cover:
1. STOPPUMPbefore proceeding.
2. CLOSEGATEVALVESin suction and discharge pipes.
3. RELEASEALLPRESSUREfrom pump and pipingsystem.
Do not block pump suction. To do so with body may cause severe or
fatal injury. Small children usingpool must ALWAYShave close adult
supervision.
PrimingPump
Release all air from filter and piping system: see filter owner’smanual.
In a flooded suction system (water sourcehigher than pump), pump will prime
itself when suction and discharge valvesare opened.
If pump doesnot prime, make sure that all valvesare open, suction pipe end
isunder water, pump suction isbelow water level, and that there are no leaks
in suction pipe. See Troubleshooting Guide, Pages10 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 isnon-toxic and will not damage plastic
system components; other anti-freezesare highly toxic and may damage plas-
tic componentsin the system.
