For ease of pump/motor removal, install pipe unions on
the suction and discharge pipes close to pump.
Pump mount must:
Be located away from corrosive or flammable liquids.
Have enough ventilation to maintain air temperature at
less than the maximum ambient temperature rating (Max.
Amb.) listed on the motor model plate. If this pump is
installed in an enclosure/pump house, the enclosure
must have adequate ventilation and air circulation to
keep the temperature in the enclosure at or below the
motor’s rated ambient temperature whenever the pump is
running.
Be solid - Level - Rigid - Vibration free. (To reduce vibra-
tion and pipe stress, bolt pump to mount.)
Allow pump suction inlet height to be at or below water
level in pool.
Allow use of short, direct suction pipe (To reduce friction
losses).
Allow for gate valves in suction and discharge piping.
Have adequate floor drainage to prevent flooding.
Be protected from flooding.
Allow adequate access for servicing pump and piping.
NOTICE:
Use Teflon tape or Plasto-Joint Stik
1
for making
all threaded connections to the pump. Do not use pipe
dope; pipe dope will cause stress cracking in the pump.
NOTICE:
Pump suction and discharge connections have
molded in thread stops. DO NOT try to screw pipe in
beyond these stops. Tighten the pump/trap fittings only as
much as required to insure a tight connection (1-1/2
turns past hand tight is sufficient). Overtightening may
damage the pump trap. Use care when using teflon tape
as friction is reduced considerably; do not overtighten
connections or damage may occur.
Teflon Taping Instructions:
Use only new or clean PVC pipe fittings.
Wrap male pipe threads with one to two layers of Teflon
tape. Cover entire threaded portion of pipe.
Do not
overtighten or tighten past thread stop in pump
port!
If leaks occur, remove pipe, clean off old tape, rewrap
with one to two additional layers of tape and remake the
connection.
NOTICE:
Support all piping connected with pump!

Piping:
To avoid strains on the pump, support both suction and
discharge pipes or hoses independently. Place these sup-
ports near the pump.
To avoid airlocking, slope suction pipe slightly upward
toward the pump.
NOTICE:
To prevent flooding when removing pump for
service, all flooded suction systems
must
have gate
valves in suction and discharge pipes.
Union available for pump discharge port (Part number
WC198-105). Use as follows for leak-free connection to
pump:
1. O-Ring and sealing surfaces must be clean.
2. Assemble handtight only! (NO WRENCHES!)
3. NO pipe compound or teflon tape on union.
4. Bond pipe to union with PVC cement.
Fire hazard. Use PVC cement only in a
well ventilated area away from flame; follow manu-
facturer’s instructions.
Fittings:
Fittings restrict flow; for best efficiency use fewest possi-
ble fittings.
Avoid fittings which could cause an air trap.
