Fig. 8.11.3-2: Air filter mat
Change the air filter mat and close the cover again.
8.12 De-aerating of the coolant circuit / freshwater
The Panda 5000i PMS is self de-aerating.
8.13 The raw water circuit
8.13.1 Clean raw water filter
The raw water filter should be released regularly from arrears. In
each case the water cock must be closed before. It is mostly
sufficient to beat the filter punnet.
If water should seep through the cover of the raw water filter, this
may be sealed in no case with adhesive or sealant. Rather must be
searched for the cause for the leakage. In the simplest case the
sealing ring between caps and filter holders must be exchanged.

8.13.2 Causes with frequent impeller waste
The impeller of the cooling water pump must be regarded as wearing part. The life span of the impeller can be
extremely different and exclusively depends on the operating conditions. The cooling water pumps of the PANDA
generators are laid out in such a way that the number of revolutions of the pump lies low compared with other
aggregates. This is for the life span of the pump a positive effect.
Unfavorably affects the life span of the impeller, if the cooling water sucking in way is relatively long or the supply is
handicapped, so that the cooling water sucking in range develops a negative pressure. This can reduce first of all
the power of the cooling water pump extremely that the wings of the impeller are exposed to very strong loads. This
