continue INSTALLATION
1) Install the pump as close to the pool as possible, to reduce
friction loss and improve ef ci
if ency, use short, direct suction
and return piping.
2) To avoid direct sunshine, heat or rain, it is recommended
to place the pump indoors or in the shade.
3) 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 f
f
or cooling.
4) The pump should be installed horizontally and xed i
i
n the
hole on the support with screws to prevent unnecessary
noise and vibration.
4.2 Pump Location
* The pump inlet/ outlet union size: optional with metric 50 or 40mm.
2) Below water level system should have an isolation valves installed on suction and return line f
f
or maintenance; however, the suction
gate valve should be no closer than seven times the suction pipe diameter as described in this section.
3) A check valve shopuld be installed if there are long pipe runs aboave water level or if is signi icant height between the return line
and
the outlet of the pump.
4) Be sure to install check valves when plumbing in parallel with other pumps. This helps prevent reverse rotation of the impeller and
motor.
4.4 Valves and Fittings
1) Check whether pump shaft rotates freely;
2) Check whether power supply voltage and frequency conform
to the nameplate;
3) Facing the fan blade, the direction of motor rotation should
be clockwise;
4) It is forbidden to run the pump without water.
4.5 Check before initial startup
4.6 Application conditions
1) For optimization of the pool plumbing, it is recommended to
use a pipe with size of 50mm. When installing the inlet and outlet
tti
i ngs
f
(joints), use the special sealant for PVC material.
2) The dimension of suction line should be the same or larger
than the inlet line diameter, to avoid pump sucking air, which will
affect the eff ci
i ency of the pump.
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, 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 close
e
r
to the front of the pump than seven times the suction line diamete
r
5) 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.
4.3 Piping
Ambient temperature
Indoor installation, temperature range:
-10 ~ 40°C
Water temperature
Salt pools
Salt concentration up to 0.5%, i.e. 5g/L
Humidity
Altitude
Not exceed 1000m above sea level
Installation
The pump can be installed max. 2m
above water level
Insulation
Class F, IP55
5°C ~ 50°C
90% RH,
(
20°C±2°C
)
The pump should be installed in an area with at least 150mm
distance around the unit away from any obstacles and away
from any corrosive products.
Suction and return connections on the pool pumps are 50mm
pressure pipe dimensions.
It is recommended to install isolation valves on the suction and
return lines for easier maintenance of the pool pump.
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.
