2. Connect the discharge pipe. The pump is equipped with a discharge connection for hose or pipe.
Piping work must not create air pocket in the middle of the piping.
NOTICE
The discharge pipe can be run vertically or horizontally, but must be without sharp bends. Excessive bending
could obstruct the flow of water, reduce the pumping volume, or clog the pump.
3. Install a non-return valve if the pump pit is deep, or if the vertical/lateral piping is too long.
4. Lower the pump into the sump pit. Attach a rope, chain, or wire to the handle of the eyebolts for lowering
and lifting the pump.
CAUTION
Make sure that the rope doesn't get tangled or twisted during installation.
5. Place the pump on a horizontal and rigid base, in an area that is free from and does not cause the pump to
take air in. This area must have a sufficient water level and collects water easily. Alternatively, the pump can
be suspended with a lifting chain just above the sump pit bottom. Make sure that the pump cannot rotate at
the startup or during operation.
NOTICE
For the water level required for operating the pump, refer to the pump's dimensional drawing that can be
obtained from our representative or company.
6. Make sure that the impeller rotation is correct.
7. Should there be any problems occurred during installation, please get in touch with a PRORIL
representative.
Float Switch Location Installation Requirement
CAUTION
Place the pump with integrated float switch hardware in an area where the float can properly and easily move
up and down without getting caught with the pit walls, cable, or lifting chains.
ELECTRICAL HAZZARD
•
A certified electrician must supervise all electrical work. Comply with all local codes and regulations.
•
Before starting work on the unit, make sure that the unit and the control panel are isolated from the
power supply and cannot be energized. This applies to the control circuit as well.
•
Leakage into the electrical parts can cause damaged equipment or a blown fuse. Keep the end of
the motor cable above the liquid level.
•
Make sure that all unused conductors are insulated.
•
There is a risk of electrical shock or explosion if the electrical connections are not correctly carried
out or if there is fault or damage to the product.
