PREVENTIVE MAINTENANCE
For better functioning and durability of your vacuum pump, some procedures are needed.
Preventive maintenance correspond to the
accomplishment of all procedures below
.
PERIODICITY
MAINTENANCE
DAILY
Vacuum pump internal cleaning:
It is recommended that a specific product for this purpose be used, for example, a
detergent which is suitable to disinfect and dissolve residues inside the vacuum
system, for it will reduce the need of cleaning and keep the suction capacity
through duct clearance. To perform this kind of cleaning, proceed according to the
cleaning product manufacturer’s instructions.
Residue filter cleaning:
Open the filter cover by turning it counterclockwise (Fig. 10, page 9), remove-it and
discard the residue in appropriate place. Wash the cover of the residue filter and
filtering element, verify if the gasket inside the cover is properly placed, and
reposition the residue filter. If the gasket is damaged, replace-it. To buy extra filtering
elements, consult your local Cristófoli authorized dealer.
ATTENTION! Never forget to
reposition the filtering element of the residue filter. Small fragments are enough
to damage the internal components of the vacuum pump.
MONTHLY
External cleaning:
Unplug the power cord and perform cleaning with a feather duster or a soft cloth,
slightly moistened with water and biodegradable neutral detergent, after it, clean
with a cloth, moistened with 70% alcohol and 1% peracetic acid. Never use
solvents or petroleum derivatives. Verify the openings at the bottom of the motor, if
there’s dirtiness accumulation on it, perform cleaning.
YEARLY
General revision and flow limiter regulation
(we recommend that this procedure
be performed by an authorized technical assistance):
Unplug the power cord and close the water supply valve. Remove the hose
connected to the water supply valve. Remove the filtering screen and take the flow
limiter out of the water inlet with a needle nose plier. Rotate the tip of the flow limiter
counterclockwise, taking care not to damage the internal rubber disc. After
removing, wash the parts below running water. When mounting it, take care not to
press the rubber disc. Reposition the set back to the valve. Reconnect the hose to
the water inlet. Turn on the vacuum pump and make the measuring test again.
Measuring test (water consumption):
Disconnect the hose from the drain exit of the
vacuum pump. Use a measuring cup with ml (millilitre) scale and a stopwatch.
Activate the vacuum pump, wait for 3 to 5 minutes, until the flow of expelled water
stay constant. Place the measuring cup at the vacuum pump water exit and collect
the expelled water for 1 minute. After this time, observe if the amount of expelled
water is 160 ml. If the result taken is different from the indicated value, perform the
procedure again.
