Operating Instructions and Parts Manual
Pool Pumps
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 larg-
er than discharge pipe. Avoid using a
suction pipe smaller than pump connec-
tion.
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
WARNING
!
All wiring must be per-
formed by a qualified
electrician. The pump
must be installed in com-
pliance 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 mm
be connected from the accessible wire
connector on the motor.
• 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
IMPORTANT: Use copper
conductors only.
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.
1. Switch OFF power.
2. Remove cover from back of motor.
3. The motor is factory wired for 230
volts.
4. Move Voltage Change Switch to 115
volts.
5. Reinstall cover to back of motor.

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

) should
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.

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.
