Operating Instructions and Parts Manual

Installation (Continued)

Consider climatic conditions when

applying adhesives. Atmospheric condi-

tions with high humidity will make the

adhesive action of certain glues less

effective. Follow the manufacturer's

instructions.

THREADED CONNECTIONS

Use only Teflon®tape or equivalent on

threaded plumbing connections. Other

pipe compounds may damage threads.

Do not use silicone or petroleum based

compounds. Do not overtighten. Hand

tightening plus 1/2 turn is sufficient.

PUMP PLUMBING

Suction pipe should be as large or larger

than discharge pipe. Avoid using a suc-

tion pipe smaller than pump connection.

1. Keep the piping as straight and

short as possible, and of suitable

size.

2. Do not connect an elbow directly

into the pump inlet. A length of

straight pipe will allow proper entry

of the water to the pump.

3. Slope horizontal runs upward to the

pump to prevent trapping air.

4. Use independent piping supports to

alleviate strain on the pump.

5. Keep as much of the suction line as

possible below the water level to

reduce priming time.

6. Install valves and unions in the

pump suction and return lines to

facilitate servicing. Valves will throt-

tle the pump discharge. Valves are

also essential for pump mainte-

nance if the system is installed

below deck level.

7. Use a check valve in the suction pipe

for inground pumps at or below the

water level if the suction lift is more

than 5 feet or the dry suction is

more than 10 feet long. Keep the

valve in the suction line fully open

during operation.

WIRING

All wiring must be per-

formed by a qualified elec-

trician. The pump must be

installed in compliance with all local

codes and the National Electrical Code.

When motor installation is within 5 ft.

(1.5 m) of the pool’s interior walls, a

solid copper bonding conductor (mini-

mum size No. 8 AWG/8.4 mm2) should

be connected from the accessible wire

connector on the motor.

WARNING

• to all metal parts of the swimming

pool

• to all electrical equipment

• to metal conduit

• to metal piping within 5 ft. (1.5 m)

of the pool’s interior walls

Refer to information on motor name-

plate for electrical service data. Install

motors with a fused disconnect switch

or dedicated circuit breaker. Be sure

wire size is sufficient for pump HP and

distance from power source. Install a

ground fault circuit interrupter for

maximum safety.

Disconnect, tag,

and lock out power

source before attempting to install, ser-

vice, relocate, or perform any mainte-

nance.

VOLTAGE SELECTOR

This pump is factory wired for 115 volts.

To change the voltage to 230 volts fol-

low the steps below:

1. Disconnect the pump from power.

2. Remove cover from back of motor

to find voltage selector (Figure 1a).

3. Pull selector knob out.

4. Rotate selector knob to correct volt-

age setting (Figure 1b).

5. Push selector knob back in place.

6. Reinstall cover to back of motor.

DANGER

Operation

Prime pump before attempting to oper-

ate. To prime pumps located above water

level, remove strainer cover, fill strainer

body with water then replace cover. If

pump and all piping is located below

water level, the pump will self prime.

After pump has been primed, energize

motor and open all suction and dis-

charge line valves. If no flow is

observed in five minutes, stop the

motor and reprime. If the pump fails to

operate, check for air leaks. Refer to

troubleshooting section.

After about 10 minutes of operation,

check the return fittings for air bubbles.

A continuous flow of air indicates leaks

in the suction line. Locate and correct

any leaks immediately.

CONTROLLING PUMP DISCHARGE

Keep the gate valve in the suction line

fully open during operation. To control

the discharge, use a valve in the return

line.

Do not retighten

strainer Ring-Lok

during operation.

Do not operate

pump with closed

suction or discharge valve.

WATER CHEMISTRY

Proper and consistent use of chemicals

is necessary to manage a water system.

Chlorine is the most commonly used

chemical to provide clean, sanitary

water. Daily administration of dry or

liquid chlorine (calcium or sodium

hypochlorite) is essential.

IMPORTANT: Maintain the correct

level of acidity or alkalinity of the pool

water. Readings above pH 7.0 are alka-

line. A pH 7.0 is neutral. Readings

below pH 7.0 are acidic. A desirable

range is 7.2 to 7.4.

CAUTION

IMPORTANT: Use copper

conductors only.
