INSTALLATION LOCATION
All S & J Series pumps are designed for flooded suction (all suction
fittings and suction piping are below water level) and will not
self-prime.

FOR SOLVENT WELD CONNECTIONS
Rigid or flexible PVC pipe can be used. Pipe ends should be clean
and free of any flash caused by the cutting operation. Be sure that the
proper adhesive is used on the type of pipe specified.
Recommended Adhesives - These are examples only and are not
intended to restrict brands.
NOTE:
A primer will assure that adhesives joints are superior.
Sureguard P-3000 has a purple tracer to qualify in areas where
codes specify a primer must be used.
CAUTION
-
We recommend that you consider climatic conditions
when applying adhesives. Certain atmospheric situations, such as
high moisture content, make the adhesive action of certain glues
less effective. Check the manufacturer’s instructions.
FOR THREADED CONNECTIONS
Use only PTFE tape or equivalent on threaded plumbing
connections. Other pipe compounds may damage threads. We do
not recommend the use of silicone or petroleum based compounds.
DO NOT OVER TIGHTEN! HAND TIGHTEN PLUS 1/2 TURN IS
SUFFICIENT.
PUMP PLUMBING
All S & J Series pumps are union connected allowing quick and
easy service without disturbing the plumbing. Two different plumbing
configurations are available offering 1-1/2” suction connection and
either 1-1/2” discharge or 1” tee discharge. These union packages must
be ordered separately. Avoid using a suction pipe smaller than pump
connection.
To maximize the 100% drain feature, keep the piping as straight
and short as possible, and slope horizontal runs so water drains
away from pump. The suction line must be installed at an elevation
below the water level when the tub is filled to guarantee flooded
suction.
ELECTRICAL DATA
If the unit is being installed for use with a swimming pool, spa, or
hot tub a solid copper bonding conductor not smaller than 8 AWG
shall be connected from the accessible wire connector on the motor
to all metal parts of the swimming pool, spa, or hot tube structure
and to all electrical equipment, metal conduit, and metal piping
within 5 feet (1.5m) of the inside walls of the swimming pool, spa, or
hot tube, when the motor is installed within 5 feet of the inside walls
of the swimming pool, spa, or hot tub.
Refer to information on motor nameplate for electrical service data. All
motors should have fused disconnect switch or circuit breaker. Be sure
wire size is sufficient for HP and distance from power source. Wiring
should be done in accordance with applicable codes by competent
electrician. We recommend the installation of a ground fault circuit
interrupter for maximum safety.
PUMP START UP
Fill tub to desired level making sure that suction fittings and jets are
below water level. Start pump and open all suction and discharge
line valves.
After about 10 minutes of operation, check the return fittings for air
bubbles. A continuous flow of air indicates a leak in the suction line.
Locate and correct any leaks immediately.
CAUTION - Do not operate pump with closed suction or
discharge valves.
TWO-SPEED PUMPS
Two-speed models are recommended in a swimming pool when
high speed is needed for maximum filtration at peak periods and
whenever turbidity levels are high. At other times, switch to low
speed. For back-washing and vacuuming, high speed is required.
In spa and hot tubs, use high speed to attain full performance in the
hydro-therapy mode. At other times, such as filter/heat cycle mode,
use low speed. Low speed provides sufficient flow to activate most spa
heaters and provides sufficient flow for filtration.
In jetted tubs, use high speed to attain full performance in the hydro-
therapy mode and use low speed for desired low flow conditions.
NOTE: Two-speed pumps must be in high speed mode to prime.
PUMP MAINTENANCE
1. Motors are self-lubricating - no lubrication is required.
2. Clean hair and lint strainer if you have a pump with strainer body.
3. Visually inspect motor for blockage of air vents on motor
shell. Remove any debris after shutting off breaker.
4. Shaft seals may become worn and must be replaced if
leakage is observed.
NOTE: If recommendations in the Troubleshooting portion do not
solve particular problem(s), please contact your local dealer for
service.
