Assemble the special skid-flange (fig. 5 – pos. D) on the delivery outlet of the pump and hook the rope
or chain to the handle or slot located on the upper part of it.
-
Lift the electric pump up to over the pit and let it slowly descend guiding the skid-flange in the guide pipes.
-
When it arrives at the bottom, the electropump will automatically connect to the support foot.
-
The hook of lifting rope or chain must be in line with the center of gravity of pump.
-
Secure the extremities of rope or chain to the upper bracket located at the edge of the pit.
-
Dispose the electric cables avoiding bends and deflections and paying attention that relevant terminals
are not in contact with water.
The correct fixed installation must include installation of a non-return valve.
The guide rails must not have any axial play as this would cause noise during pump operation.
During positioning of the pump, air may remain blocked inside the pump body. The air may be
removed from the pump body by installing the pump after having removed the cap of the vent
hole positioned on the side of the pump. (Fig. 6).
Attention, the vent hole is on the side opposite the oil filling holes.
5.2 Submerged installation on a support base
Delivery pipe must have diameter not inferior to the pump inlet.
When using a flexible pipe , it is advisable a reinforced pipe with metallic spiral which maintains the section
unchanged even in presence of bends.
The eventual foot valve and gate valve must be assembled at a distance of approx 50 ÷ 200 cm. in a section of
metallic pipe (rigid). Special attention should be paid to the positioning of electric cables in order to avoid
possible bending, pressing, lifting and that the same are accidentaly sucked by the pump.
The free end of the cable must not be submerged, as water may penetrate through the cable
into the motor.
