3 INSTALLATION
3.1 Unpack and inspect
Take care when you unpack the pump to avoid
excessive shocks which could damage the bearings
and reduce the life of the pump. The pump is
supplied with the inlet and the outlet sealed to
prevent entry of dust and vapour. Do not remove
these seals until you are ready to install the pump on
your vacuum system.
Remove all the outer cardboard packaging and
check the pump. If the pump is damaged, notify your
supplier and carrier in writing within three days;
state the item number of the pump together with
your order number and your supplier's invoice
number. Retain all the packing materials for
inspection. Do not use the pump if it is damaged.
Check that your package contains the items listed in
Table 6. If any of these items is missing, notify your
supplier in writing within three days.
If the pump is not to be used immediately, store the
pump in suitable conditions as described in
Section 6.1.
It is advised that you retain all packing materials for
use should you return the pump for service.
WARNING
The EXT555H DN160CF pump
variant weighs 21 kg. Take care when
handling the pump and ensure that
you grip it firmly by the inlet flange
when manoeuvring it.
