3. Installation Instructions

3.1 Before Installation

1. Electric pumps shall be comprehensively
checked for damage during transportation
and storage prior to installation and use, e.g.
whether cable and terminal box are in good
condition. In case of any damage, please
have the replacement or repair carried out
by a specialist.
2. Before operation, the cold insulation
resistance of the electric pump must be
fully checked. It must be at least 100 MΩ,
otherwise suitable measures must be taken
and operation is not permitted until the
relevant requirements have been met.
3.2 Installation
1. During the wiring of a three-phase electric
pump, please properly install an electrical
leakage protection device to the pump. For
those pumps that provided with control box,
please make the connection according to
the diagram in the control box or related
instruction manual.
2. Connect a delivery pipe (whose specifications are selected
based on part 2) to match with the discharge chamber. For
example, tighten a soft delivery pipe with the iron wire or a
clamp or connect a steel-type delivery pipe with the screwed
joint, and then tie a rope to the delivery chamber for the
purpose of lifting and placing.
3. Do not strike or press the cable or use it as a lifting rope.
When the electric pump is operating, do not arbitrarily pull the
cable, in order to to prevent the cable from being damaged and
causing any electric shock accident. Upon installation, bind
the cable to the delivery pipe or take other proper measures
for protection to avoid any tensile deformation due to the great
dead-weight of the cable.

3.3 During Usage

1. Before putting the electric pump into water, please carry out
a test run for less than 10 seconds and simultaneously check
whether the rotating direction of the pump is the same as
indicated by the indicating arrow on the nameplate.
