2. Installation and piping
2.1 Installation site
2.1.1 For secure operation, please mount and
bolt the pump base to the foundation.
2.1.2 Select a dry and good ventilated site and
provide accessible space around the pump
for future maintenance and service.
2.1.3 Make sure the ambient temperature is
below 40oC(104oF) and the flowing liquid
temperature does not exceed 90oC(194oF) .
2.1.4 Do not operate the pump under explosive
environment.
2.1.5 When the pump is installed outside, please
provide a suitable cover to protect it from
weather and frost. Please do not allow any
foreign objects fall into the motor fan
cover.
2.1.6 Horizontal installation is recommended.
When it is installed in other positions,
please provide drain holes to allow
drainage of the pump.
2.2 Electrical connection
2.2.1 This mark located outside the
connection box is a warning for
an electrical hazard.
2.2.2 The electrical connection should be carried
out in accordance with local regulations.
The operating voltage and frequency are
marked on the nameplate. Please make
sure that these data match with your job
requirement. For your safety, be sure the
circuit breaker is in your system and
grounding is properly connected to prevent
from electric shock.
2.2.3 Three phase motors must be connected to a
motor starter for protection of overload and
single phase running. Please be sure if the
direction of rotation is correct. For three
phase motor you can reverse the direction
of rotation by interchanging any two of the
incoming supply wires. Before your first
operation, please place a screwdriver
against the shaft at motor end and turn by
the direction of rotation to see if rotor
spins freely.
2.2.4 The position of the connection box is
adjustable. It can be turned either side
before the pump is installed. The preset
position from the factory is on the top of
the motor. To change the position of the
connection box, please remove the bolts
on the motor frame (4 bolts which are
bolted into the chamber) and turn the
stator housing to the required position.
Replace the screws and tighten securely.
