Installation
Installation Location
Locate pump as close to pool/spa as possible, preferably in a
dry, well ventilated area away from direct sunlight. It should
be on a hard, level surface. Give consideration to:
1. Drainage – away from pump.
2. Ventilation of pump motor.
3. Access for future servicing and winterizing.
4. Protection from the elements.
Pumps without strainer bodies are designed for flooded
suction (all suction fittings and suction piping below water
level) and will not self-prime. Consequently, the pump
must be installed at an elevation that is below water level
when pool or spa is filled; however, if suction line valves are
installed, the pump may be closed for priming. Keep vertical
distance to a minimum if you choose to mount pump above
water level.
Pumps with strainer bodies are self-priming but should be
mounted as close to the water level as possible or below for
ease in priming.
Vertical Water Discharge
DualFlo pumps come set for vertical discharge and can be
changed to horizontal.
WARNING: Make sure the power has been cut off before
performing the below actions.
1. Open the clear cover and remove the clip located inside
the strainer housing. Then detach the strainer housing
from the rest of the pump unit.
2. Unscrew and remove all the screws from the pump cover
and remove the pump cover from the rest of the pump
unit.
3. Unscrew and remove the cap from the back of the motor,
then unscrew the four (4) long bolts located on the
“four-corners” of the motor.
4. Using a screw driver, lock the middle Axis on the motor
and turn the impeller (located on the other end of the
motor) until the impeller is removed. Remove the pump
housing from the motor.
5. Separate the motor mounting plate from the pump
housing and rotate the pump housing 90 degrees.
The discharge pipe area will now be facing side ways/
horizontal. Reconnect the motor mounting plate to the
pump housing.
6. Reverse instructions 4 to1 to reassemble the pump.
Electrical Data
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
pump HP and distance from power source. Wiring should be
done in accordance with applicable codes by a competent
electrician. We recommend the installation of a ground fault
circuit interrupter for maximum safety.
General Plumbing
FOR SOLVENT WELD CONNECTION -
Rigid or flexible PVC
pipe can be used. Pipe ends should be clean and free of any
flash cause by the cutting operation. Be sure that the proper
adhesive is used on the type of pipe specified.
NOTE: A primer will assure that adhesive joints are
superior. Suregard 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
adhesive action of certain glues less effective. Check the
manufacturer’s instructions.
FOR THREADED CONNECTIONS -
Use only Teflon 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 ½ TURN IS
SUFFICIENT.
Pump Plumbing
Suction pipe should be as large or larger that discharge pipe.
Avoid using suction pipe small that pump connection.
Keep the piping as straight and short as possible, and of
suitable size. Avoid connecting an elbow directly into the
pump inlet (use a length of straight pipe to allow a proper
entry for the water). Arrange horizontal runs to slope
upward to the pump to prevent high spots that could form
air pockets. Support the pipe independently so that it places
no strain on the pump. Keep as much of the suction line
as possible below the water level to reduce priming time.
Install valves and unions in the pump suction and return
lines to facilitate servicing. Valves are recommended for
throttling maintenance if the system is installed below deck
level. Suction valves are essential for priming all pumps
without strainer bodies installed above water level. Pumps
with strainer bodies are self-priming, nevertheless, we
recommend the use of check valve in the suction pipe at
or below the water level if the suction lift is more that five
feet or if the dry suction is more that ten feet long. Keep the
valve in the suction line fully open during operation.
