5. Identification
5.1 Nameplates
The pump and motor nameplates are positioned on
the motor fan cover or terminal box.
The data and information on the pump nameplate
are described in the table below. See the nameplate
in fig. 6 on page 15.
The data and information on the motor nameplate
are described in the table below. See the nameplate
in fig. 7 on page 15.
6. Mechanical installation
Before installing the pump, check that the pump type
and parts are as ordered.
6.1 Installation of pump
The pump must be installed with the motor shaft
vertical. It must be mounted on a plane surface and
secured by foundation bolts.
The pump should be installed so that the suction
pipe is as short and the suction lift as small as
possible.
The pump should be sited in a well ventilated but
frost-free position. See section
10.1 Frost protection
.
The pump may be sited outdoors, but it should be
protected from the elements by means of a suitable
cover.
The pump should be installed with easy access for
inspection, maintenance and service.
6.2 Pipework
It is advisable to fit isolating valves on either side of
the pump. It is thus not necessary to drain the
system if the pump needs service. If the pump is
installed above the liquid level, a non-return valve
must be fitted in the suction pipe below the liquid
level.
The pump must not be stressed by the pipework.
The pipework must be correctly sized taking due
account of the pump inlet pressure.
If the pump is installed at the lowest point of the
system, impurities and sludge may accumulate in the
pump.
Install the pipes so that air locks are avoided,
especially on the suction side of the pump.
