Installation, use and maintenance
FILTERS
CUBE MC features a number of filters having different functions. The inspec-
tion and cleaning (or replacement) of each filter is crucial to ensure:
- The protection of the various station components (pulser, pump, nozzle).
- Station performance remains high over the years (maximum flow rate).
- Protection of the engines using the dispensed diesel fuel.
ATTENTION Dirty or partially blocked filters can increase flow resistance and cause a
considerable reduction in the maximum flow rate of the pump. Dirty or
blocked pump suction filters also cause a big increase in vacuum during
suction and this in turn can make the pump particularly noisy.
PUMP FILTER
(ONLY AC
VERSIONS))
This is fitted in the pump body, as a standard PANTHER pump fitting.
To inspect and clean it:
1 - Loosen the two filter cover screws and take the cover off.
2 - Take out the mesh filter with the aid of a pair of pliers.
3 - If the filter needs cleaning, wash and blow it.
4 - Put the filter carefully back in its housing in the pump body, making sure it
does not protrude from the cover housing.
5 - Check and clean the flat seal, reposition the cover and tighten the screws.
PULSER
FILTER
The pulser filter represents a further protection against the risk of foreign
bodies entering the oval-gear pulser. Because this filter is fitted downstream
of the pump suction filter, it does not require regular inspection and clean-
ing. Should the need arise however and/or in case of special maintenance, it
can be cleaned as described in the PULSER MANUAL, after removing the
roof of CUBE MC (if necessary) by means of its relevant upper screws (see
exploded view).
