Changing the pump inlet filter
Verify the filter at the entrance of the pump,
and change it if dirty or obstructed, therefor:
Open the filter pulling the flap.
Take out the 2 cotton filters, throw away those
which are soiled and replace them with new
ones. Always use 2 filters.
Close the filter and check the airtightness.
Checking the suction circuit
To determinate if there is obstruction in the
suction circuit:
- Press the vacuum pump start button, with
the desoldering iron at a temperature of
not less than 250°C to keep the tin solder
melted.
The suction indicator
should not go beyond the
green zone. If it runs into
the red zone, this will mean
that the suction circuit is
obstructed in some way
and the tip
unclogging or the filters
replacing.
To detect air leaks in the
circuit:
- Obstruct the tip inlet orifice
by pressing down on a
silicone disc, or bend the
t u b e c o n n e c t i n g
desoldering iron to the
filter.
- Press the vacuum pump start button.
The vacuum indicator should run into the red
zone (60% and 80% vacuum). If not, this means
air is getting in somewhere, either through the
desoldering tip, the tank stopper, or the pump
inlet filter stopper, or because the air pump does
not function correctly due to dirty valves which
occurs when the air filter has not been used
correctly.
