5. INSTALLATION
1. Make sure this pump is horizontally installed.
2. Make sure that the power source is correct before power connections. The correct
connections as below:
3-Phase 1-Phase
W=White BK=Black BL=Blue R=Red
C=Capacitor
3. Use diameter of 7-8mm power cable (3 or 4-wires), turn tight cable hold nut and use gasket
between cover and power box. Ground terminal must connect to the ground wire and should
be fixed.
4. Please pay attention to the installation environment to avoid places with high temperature
and humidity or poor ventilation. Continuous operation> 2 hours, the motor temperature can
reach 65~75 (three phase) or 75~85 (single phase). This is a normal phenomenon and
will not affect the life of the motor, but a well-ventilated place can effectively dissipate heat
and reduce acid , The environmental concentration of alkali or volatile chemicals prolongs
the life of the pump.
5. This product can be installed on the ground or on the wall. Must secure this product to avoid
looseness cause by vibration.
6. It is necessary to tighten the joints with bare hands when installing. Do not use tools to
handle the plastic joints to avoid damage.
7. After fixing the pump, connect certificated hose/pipe to the inlet/outlet connector and the
foot-valve (with filter). The foot-valve should 10-15cm higher than the bottom of the source
tank to prevent from sucking sediments.
8. Notices of piping (Piping configuration consult scheme 1)
1. If pump location is above chemical container, do not excess 2.0meters higher than the
chemical lowest level in the container and check valve must be installed vertically.
High suction head may lead fail inhalation. Permissible suction head is affected by
Liquid viscosity, specific gravity, pipeline conditions. (We do not guarantee suction
head of this product)
2. When input hose is empty, pump may not be able to suck liquid into pump head
automatically. In this case you can try to full the input hose with liquid then
raise it up higher than pump head and start pumping. This procedure may solve
suction problem. (If a pipe injector will be install, install it after pump can pump
out normally.)
