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 needs
unclogging or the filters
replacing.
To detect air leaks in the
circuit:
- O b s t r u c t t h e
orifice by pressing down
on a silicone disc, or bend
the tube connecting the
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 that the pump suction is not
powerful enough because the valves need
cleaning.
Cleaning the vacuum pump valve
Open the control unit as follow:
- Disconnect and open the control unit.
- Turn it upside down, remove the four rubber
feet and take out the four inner screws.
- Return the station to its normal position and
lift up the lid by getting hold of the sides.
- Undo the four screws fastening the pump
cover.
t i p i n l e t
- Clean the valve with a cloth dampened in
alcohol. If it is too soiled, replace it with
new one. Ref. 0982970.

control unit switches off completely.
reconnect, use the main start switch. The
following messages will appear on the display:
- BLANK DISPLAY
Electricity supply failure. Check that the ap-
paratus is turned on or whether the fuse at
the back of the box (T 315 mA) has blown.
- ERR 1
The temperature does not rise. Possible
causes: heating element fused, heating ele-
ment supply cable cut, faulty triac. Check
and replace as required.
- ERR 2
The temperature rises uncontrollably.
Possible causes: crossed Triac.
- ERR 3
There is no thermocouple reading. Possible
causes: the soldering iron is not connec-
ted to the unit, thermocouple open,
soldering iron cord broken.
- ERR 4
Irregular thermocouple readings. Possible
causes: thermocouple or its connections in
bad condition.
- ERR 5
