The pump mount must be located away 
from corrosive or fl ammable chemicals.
Do not connect the pump to a municipal 
water system. The pump is only designed for 
pool or spa installation. The pump must be 
installed with at a minimum of 2 main drains 
equipped with certifi ed anti-entrapment cov-
ers that comply with ASME/ANSI A119.19.8 
standard (see Figure 2). All air must be re-
moved from piping system before operating 
or testing equipment (see fi lter manual).
THREADED CONNECTIONS
Use only Tefl on
®
 tape or equivalent on 
threaded plumbing connections. Other pipe 
compounds may damage threads. Do not 
use silicone or petroleum based compounds. 
PUMP PLUMBING
Suction pipe should be as large as or 
larger than discharge pipe. Avoid us-
ing a suction pipe smaller than pump 
connection. The pump is designed to 
accept either 2 or 3 inch suction piping. 
Larger diameter pipes reduce noise and 
improve performance. 
1.  Keep the piping as straight and short 
as possible, and of suitable size.
2.  Avoid connecting 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 
reduce 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 are also essential for 
pump maintenance if the system is 
installed below pool water level.
7.  Keep all valves fully open during 
operation. Partially closed valves waste 
energy!
 Use 
Tefl on tape for 
making threaded 
connections to the pump. Do not use 
pipe dope.
TEFLON TAPING INSTRUCTIONS
Use only new or clean PVC pipe fi ttings. 
Wrap male pipe threads with one to 
two layers of Tefl on tape. Cover entire 
threaded portion. Do not over tighten.  
If leaks occur, remove pipe, clean off old 
tape, rewrap with one to two additional 
layers of tape and remake the connection.
 
Internal - 2 in. NPT 
  are available for direct 
connection to pipe. The suction line is 
also designed to accept 3 in. NPT external 
threaded connection. For best results use 
the larger diameter suction line.
FITTINGS
Fittings restrict fl ow; for best effi ciency 
use fewest possible fi ttings. Avoid fi ttings 
which could cause an air trap. Pool fi ttings 
must conform to International Associa-
tion of Plumbing and Mechanical Offi cials 
(IAPMO) standards. Use only non-entrap-
ping suction fi tting or double suction.
PRIOR TO PRESSURE TESTING
•  Securely tighten knobs, drain fi ttings, 
lid, and system accessories
•  Air may collect at the highest point in 
the plumbing system. Normally an air 
purge valve is provided with the pool 
fi lter. Consult pool fi lter instruction 
manual for air purging instructions. 
•  Basket lid must be rotated and locked 
into position as indicated in Figure 3.
•  Test system at a water pressure of 25 
psi or less
•  Water Temperature for test must be 
less than 100° F
•  After 24 hours visually check system 
for leaks.
POOL PUMP SUCTION REQUIREMENTS
 
Pump suction is
 
  hazardous and can trap, 
drown or disembowel bathers. Do not use or 
operate swimming pools or spas if a suction 
outlet cover is missing, broken, or loose. 
Follow the guidelines below for a pump 
installation which minimizes risk to users of 
pools and spas.
 
Ground the motor 
 before connecting 
to electrical power supply. Failure to 
ground the motor may cause severe or 
fatal electrical shock hazard.
ENTRAPMENT PROTECTION
The pump suction must be designed to 
eliminate the possibility of suction entrap-
ment or hair entrapment/entanglement.
SUCTION COVERS
All suction inlet covers must be maintained 
and replaced if cracked, broken, or missing.
See Figure 2 for outlet cover certifi cation 
requirements.
TESTING AND CERTIFICATION
All suction inlet covers must comply with 
ASME/ANSI A112.19.8 specifi cations for 
suction fi ttings for use in swimming pools, 
spas and whirlpool bathtub applications. The 
product must be tested for compliance with 
the standards and the certifi cation must be 
included with the components.
Single or Multiple Pump Circulation Sys-
tems must be provided with a minimum of 
2 (two) suction inlets of the approved type.
Do not install multiple pumps in one 
hydraulic circuit. The pump is not designed 
to accept output fl ow from another pump. 
Do not allow water to back fl ow through 
the pump. Water fl owing in the discharge 
and out the suction during an upset 
condition can cause the motor to rotate 
backwards. Never attempt to start pump if 
shaft is rotating due to a hydraulic turbine 
action, this could cause pump to operate in 
reverse and damage internal components.
 
Any pool or spa 
 should immediately 
be closed if the cover or grate is 
damaged or missing.
OUTLETS PER PUMP
Provide at least two hydraulically balanced 
main drains, with covers for each swimming 
pool pump suction line. The centers of the 
main drains suction fi tting must be at least 
three feet apart (see Figure 2). The system 
must be built so that it cannot operate with 
the pump drawing water from only one 
main drain. Two main drains must be con-
nected to the pump whenever it is running.  
If two main drains run into a single suction 
line, the single suction line can be equipped 
with a single valve that shuts off both main 
drains from the pump. A valve in each 
suction line is not allowed.
