BEFORE INSTALLATION

The product should be installed and maintained by
personnel who are familiar with instruction manual
and have professional qualification certificate;
installation and operation must conform to local
laws and practical standard; install pipeline properly
according to instruction manual and anti-freezing
measures are taken to pipeline.
Installation precautions of inlet water pipes (Fig. 10,11)
1. Do not use soft rubber hose to avoid sucking flat
during the installation of electric pumps.

/hr)
WARNING
2. Bottom valve is vertical and installed above water
bottom 30cm to avoid sucking silt.
3. Joints of inlet water pipes must be sealed and have
elbows as few as possible, otherwise no water will
be drawn.
4. Diameter of inlet water pipes should be at least the
same as that of water inlet to prevent great loss of
water and influence water property.
5. Notice water level decline when using, and bottom
valve should not break the surface of water.
6. When inlet water pipes are longer than 10m or inlet
water pipes are lifted more than 4m, inlet water
pipes diameter must be greater than that of water
inlet of electric pumps.
7. For additional protection it is recommended to install
in line filters
Installation precautions of outlet water pipes (Fig. 12)
Diameter of outlet water pipes should be at least the
same as that of water outlet to minimize pressure,
Choice of installation location (Fig. 13)
When installing pumps, inlet pipelines should be
as short as possible and elbows should be as few
as possible. Pumps should be placed in the well-
ventilated environment. Pumps may be installed
outdoor, but they must be covered to prevent rain
damage and frost.

INSTRUCTIONS

Examine screw plug for water drainage (Fig. 14)
Before using pumps, examine whether screw plug
for water drainage has been installed properly or not
and screw on manually or with tools.
Set inlet water pipes (Fig. 15)
Water pumps are connected with circuits:
Steel wire hose or corrugated pipe (2);
Removable connection nut (3);
Water inlet transfer (4);
Correct operations are as follows: screw water inlet
transfer to water inlet of pumps, and then screw
removable connection nut to water inlet transfer;
meanwhile pay attention to sealing pipelines, to
ensure correct operation check all connections are
sealed correctly.
Set outlet water pipes (Fig. 16)
Installation of outlet water pipes is shown as Fig.16,
the same as installation of water inlet pipes; pay
leakage is as follows:
<1> Increase usage cost;
<2> Reduce service life of pumps.
