ENGLISH
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.
Detecting air leaks in the circuit
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 pushbutton vacuum pump.
If the red led lights up, there is no loss of
suction. Otherwise air gets into the system at
some point. This can occur at the desoldering
tip, or may be caused by the lid of the deposit,
lids of filters or because the air pump does not
function correctly due to dirty valves which
occurs when the air filter has not been used
correctly.
Cleaning the vacuum pump valve
Open the control unit as follow:
- Disconnect the control unit.
- Turn it upside down, remove the fixing
screws.
- Return the station to its normal position and
lift up the lid.
- Undo the four screws fastening the pump cover.
t h e
- Clean the valve with a cloth dampened in
alcohol. If it is too soiled, replace it with new
one. Ref. 0982970.
