PUMP INSTALLATION

4.1

INSTALLATION INTO PIPE LINES

Pump must be built with electromotor shaft in horizontal position (fig. 3.1, page 13). Allowed and
forbidden positions are shown in fig. 3.2. The arrow on pump plate shows direction of medium flow.
Control box can be moved in position 12h, if there is not enough space for electric connection. Other
positions of control box are not allowed. Moving of control box should be made like shown in fig. 3.3.
Before moving control box pump must be emptied of medium.
Before starting, pump must be filled with medium and ventilated. For appropriate running the
pressure must be provided on suction side of pump.
Pumps does not need to be ventilated. When the system is ventilated they ventilate by themselves.
Air in pump causes noise. After short working period noise will disappear.
In its operational phase the pump heats up or gets heated up by the pumped medium, therefore it
must not be touched – burn hazard! The allowed operating area of the pump is determined by the
diagram in these instructions.
