4. INSTALLATION
4.1. Pump Location
1
．
Locate pump as close to pool as practical and run suction lines as direct as possible to
reduce friction loss.
2
．
To avoid direct sunshine or heat, It is recommended to place pump indoor or in the shade.
3
．
Do NOT install pump in a damp or non-ventilated location. Keep motor clean. Pump motors
require free circulation of air for cooling.
4.2. Piping
1). For improved pool plumbing, it is recommended to use a larger pipe size. When installing
the inlet and outlet fittings (male adaptor), use thread sealant.
2). Piping on the suction side of the pump should be the same or larger than the return line
diameter.
3). Plumbing on the suction side of the pump should be as short as possible.
4). For most installations we recommend installing a valve on both the pump suction and return
lines so that the pump can be isolated during routine maintenance. However, we also
recommend that a valve, elbow or tee installed in the suction line should be no closer to the
front of the pump than five times the suction line diameter.
4.3. Valves and Fittings
1). Do not install 90° elbows directly into pump inlet. Elbows should be no closer than 250mm
to the inlet. Joints must be tight. Suction line diameter must equal or be larger than the
discharge line diameter.
