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 it is 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 consider-
ably; 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 addi-
tional layers of tape and remake the connection.
NOTICE: Support all piping connected with pump!
Piping:
Use at least 1-1/2" (38mm) IPS PVC pipe with 5” (127mm) trap. Increase size
if a long run is needed.
To avoid strains on the pump, support both suction and discharge pipes
independently. Place these supports near the pump.
To avoid a strain left by a gap at the last connection, start all piping at the
pump and run pipe
away
from the pump.
Never use a suction pipe smaller than pump suction connection.
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.
Plastic pipe will expand and contract as the temperature changes. To allow
for this, use an expansion joint or flexible piping.
Union provided for pump discharge port. Use as follows for leak-free con-
nection 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.
Use PVC cement only in a well ventilated area away from flame;
FOLLOW MANUFACTURER’S INSTRUCTIONS!
