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

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.

Allow for fresh air ventilation.

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 roof runoff or irrigation nozzles.

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.

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.

NOTICE: Support all piping connected with pump!

1Lake Chemical Co., Chicago, Illinois

Figure 1

Piping:

Use at least 2" IPS PVC (51mm) pipe. Increase size if a long run is needed.

To avoid strains on the pump, support both suction and discharge pipes inde-

pendently. 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.

Never use a suction pipe smaller than pump suction connection.

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.

Pump suction port should be the highest point in the suction line.

Fittings:

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

Pool fittings must conform to International Association of Plumbing and

Mechanical Officials (IAPMO) standards.

Use only non-entrapping suction fittings or dual suction outlets installed at

least 3’ (1M) apart.

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 name-

plate rated voltage or motor may overheat, causing overload tripping and re-

duced 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 Figure 3); 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 Figure 3) to re-

inforcing 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 ap-

pliances 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 dan-

gerous 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

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.

4. NEVER tighten or loosen clamp while pump is operating!

If pump is being pressure tested, be sure pressure has been released be-

fore 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;

fill trap and pump with water.

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)! Use a wrench only

if necessary to remove lid!

Pump should prime now. Priming time will depend on vertical length of suc-

tion 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, and that there are no leaks in suction pipe.

See Troubleshooting Guide, Page 11.

Routine Maintenance

The only routine maintenance needed is inspection/cleaning of trap basket.

Debris or trash that collects in basket will choke off water flow through the

pump. Follow instructions below to clean trap:

1. Stop pump, close gate valves in suction and discharge, and release all pres-

sure from system before proceeding.

2. Unscrew trap lid (turn counterclockwise). If necessary, use a lever such as a

board or long screwdriver between lugs on trap cover.

3. Remove strainer basket and clean. Be sure all holes in basket are clear,

flush basket with water and replace in trap with large opening at pipe con-

nection port (between ribs provided). If basket is replaced backwards cover

will not fit on trap body.

4. Clean and inspect lid “O” Ring; reinstall on trap cover.

5. Clean “O” Ring groove on trap body and replace lid. To help keep lid from

sticking, tighten hand tight only (no wrenches!).

6. Prime pump (see priming instructions).

Hazardous suction.

Can trap hair or

body parts, causing

severe injury

or death.

Do not block

suction.

Draining Pump

1. Pump down water level below all inlets to the pool.

To avoid dangerous or fatal electrical shock hazard, turn OFF power to

motor before draining pump.

2. Remove trap cover and use low pressure air to blow accumulated water

from the piping system. Lugs have been provided on the trap lid to use a

lever or pry bar for loosening.

3. Cap inlet piping after draining to keep water out of the pipes.

4. To prevent pump from freezing, remove trap cover and drain the tank body

through the drain plugs (Key No. 20, Page 12). Clean pump and trap basket

thoroughly; replace trap cover.

NOTICE: Tighten trap cover by hand only (no wrenches)! Use a lever or

wrench only if necessary to remove cover! If pump is not anchored, use

caution not to break attached piping!

5. Be sure motor is kept dry and covered.

Storage/Winterizing:

Explosion hazard. Purging the system with compressed air can

cause components to explode, with risk of severe injury or death. Use only a

low pressure (below 5 PSI), high volume blower when air purging the pump,

filter, or piping.

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 plas-

tic components in the system.

Drain all water from pump and piping when expecting freezing temperatures

or when storing pump for a long time (see instructions below).

Keep motor dry and covered during storage.

To avoid condensation/corrosion problems, do not cover pump with plastic.

For outdoor/unprotected installations:

1. Gravity drain system as far as possible.

2. Enclose entire system in a weatherproof enclosure.

3. To avoid condensation/corrosion damage, allow ventilation; do not wrap

system in plastic.

4. Protect areas which retain water with non-toxic propylene glycol antifreeze

(“RV antifreeze”). Use a 40% propylene glycol/60% water solution to pro-

tect pump to -50°F (-46°C).

5. Use if union couplings will allow pump to be disconnected and stored in-

doors.

Startup For Winterized Equipment

1. Remove any temporary weather protection placed around system.

2. Follow filter manufacturer’s instructions for reactivation of the filter.

3. Inspect all electrical wiring for damage or deterioration over the shutdown

period. Have a qualified serviceman repair wiring as needed.

4. Inspect and tighten all watertight connections.

5. Open all valves in suction and return piping.

6. Remove any winterizing plugs in piping system.

7. Drain all antifreeze from system.

8. Close all drain valves and replace all drain plugs in piping system.

9. Prime pump according to instructions on Page 7.

Hazardous voltage.
