Piping, Fitting And Valve Installation - Pentair WATERFALL AF-75 Guide D'installation Et D'utilisation

Piping, Fitting and Valve Installation

1. Use thread seal tape or pipe sealants on all male connections of pipes and fittings. Use only pipe sealant
compounds suited for plastic pipe. DO NOT USE PETROLEUM BASED PRODUCTS.
2. Support pipe to prevent strains on the systems filter, pump and valves.
3. When connecting fitting to the pump, apply a pipe sealant to the threads and then hand tighten plus 1½ turns. DO
NOT OVERTIGHTEN.
4. Long piping runs and elbows restrict flow. For best efficiency, use the fewest possible fittings, large diameter pipe
(at least 1.5 inches) and locate equipment as close to the pool as possible. The pump suctions line should not be
smaller than the pipe size on the inlet of the pump.
5. Suction fittings must conform to ASME/ANSI A 112.19.8 M Standards. Use double suction fittings.
6. For most installations Pentair recommends installing a valve on both the pump suction and return lines so that
the pump can be isolated during routine maintenance. We also recommend a valve, elbow or tee installed in the
suction line should be no closer to the front of the pump than five (5) times the suction line pipe diameter. See
Figure 1 on previous page.
Example: A 1.5 inch pipe requires a 7.5 inch (19 cm) straight run in front of the suction inlet of the pump. This will
help the pump prime faster and last longer.
Note: DO NOT install 90° elbows directly into the pump inlet and outlet.
7. Maximum operating pressure of this pump is 50 PSI. NEVER OPERATE THIS PUMP ABOVE THIS PRESSURE.
8. This pump is NOT intended to be operated in series with other pumps.
