Installation

3.1 Pump Location

– Install the pump as close to the pool as possible. To reduce friction loss and improve efficiency, use short,
direct suction and return piping.
– To avoid direct sunshine, heat or rain. It is recommended to place the pump indoors or in the shade.
– DO NOT install the pump in a damp or non-ventilated location. Keep pump and motor at least 150mm away
from obstacles, pump motors require free circulation of air for cooling.
– The pump should be installed horizontally and fixed in the hole on the support with screws to prevent
unnecessary noise and vibration.
3.2 Piping
– For improved pool plumbing, it is recommended to use a pipe with size of 63mm. When installing the inlet
and outlet fittings (joints), use the special sealant for PVC material.
– Piping on the suction side of the pump should be the same or larger than the inlet line diameter, to avoid
pump sucking air, which will affect the efficiency of the pump.
– Plumbing on the suction side of the pump should be as short as possible.
– For most installations we recommend installing a valve on both the pump suction and return lines, which is
more convenient for routine maintenance. However, we also recommend that a valve, elbow, or tee installed
on the suction line should be no closer to the front of the pump than five times the suction line diameter.
– Pump outlet piping system should be equipped with a check valve to prevent the pump from the impact of
medium recirculation and pump-stopping water hammer.
3.3 Valves and fittings
– Elbows should be no closer than 350mm to the inlet. Do not install 90° elbows directly into the pump inlet/
outlet. Joints must be tight.
– Flooded suction systems should have gate valves installed on suction and return line for maintenance;
however, the suction gate valve should be no closer than seven times the suction pipe diameter as
described in this section.
– Use a check valve in the return line when using this pump for any application where there is significant
height to the outlet of the pump.
– Be sure to install check valves when plumbing in parallel with other pumps. This helps prevent reverse
rotation of the impeller and motor.
3.4 Check before initial startup
– Check whether pump shaft rotates freely;
– Check whether power supply voltage and frequency conform to the nameplate;
– Facing fan blade, the direction of motor rotation is clockwise;
– It is forbidden to run the pump without water.
