Pump Mount - Pentair STA-RITE SILENTFLO SF550100 Owner's Manual

PUMP MOUNT

Pump mount must:
1. Be located away from corrosive or flammable chemicals. Have enough ventilation
to maintain air tempertaure at less than the maximum ambient temperture rating.
If this pump is installed in an enclosure/pump house, the enclosure must have
adequate ventilation (200sq.cm min, inlet & outlet) and air circulation to keep the
temperature in the enclosure at or below the motor' s rated ambient temperature
whenever the pump is running. Keep rear of motor clear (150mm).

2. Be solid, level, rigid and ribration free. (To reduce vibration and pipe stress, bolt
pump to mount). Fixing holes accept 12mm fasteners.
3. Allow pump suction inlet height to be as far below water level as possible.
4. Allow use of short, direct suction pipe (to reduce friction losses).
5. Allow for shut-off valves in suction and discharge piping.
6. Have adequate floor drainage to prevent flooding.
7. Be protected from excess moisture
8. Allow adequate access for servicing pump and piping.
We recommend mounting the pump on a concrete platform for quietest performance.
If making connections to the internal threaded ports, use Teflon tape
do not use glue as this will cause stress fractures in the pump ∙ Wrap
male pipe threads with a sufficient number of layers of Teflon tape.
Cover entire thread portion. Do not overtighten or tighten past thread
stop in pump port.
If leaks occur, remove pipe, clean off old tape, wrap as previously
with one to two additional layers of tape and remake the connection.

Piping
Support all piping connected to the pump.
∙ Use at least 2" (50mm) PVC pipe. Increase size if a long run is needed.
∙ To avoid stress on the pump, support both suction and discharge pipes
independently.
∙ Place these supports as close to the pump as possible.
∙ 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 connections (2"/50mm).
• To avoid airlocking, slope suction pipe slightly upward toward the pump.
• Do not use an elbow near the suction port of the pump. Use a straight length of pipe
B
into the suction port.
∙ Use only new or clean PVC pipe fittings.
To prevent flooding when removing pump for service, all flooded suction systems must
have shut-off valves in suction and discharge pipes.
Fittings
Fittings restrict flow; for best efficiency use fewest possible fittings. Avoid fittings
which could cause an air trap.
Pool Outlets
Use only non-entrapping suction fitting or double suction conforming with the
AS1926.3 2010 (R2016) standard.
DO NOT use sealants which are incompatible with pipe fittings.
