4
Clean the connection and the water level pipe on the drain valve (do not blow i the
tube towards the CPU).
5
Grease the drum bearings (2 greasing point on each bearing). Use the right pump
and grease by slow and not brutal injections. Use lithium soap grease, drop point
190°C (374°F) and penetration 250/300 (see lubrication table in the following
pages).
6
Check the pipes of the heating rack. Clean if necessary. The frequency of your
visits should depend on the degree of deposits.
Nota :
the gas exchanger never completely drains from its water ; because the
position of the machine's connections are higher than the exchanger's.
Every month, it is then necessary to run a special scaling programme (antiliming)
with a rinse making sure that the circulation pumps runs, i.e. : with a programmed
temperature.
Maintenance of the gas exchanger
a) Carry out a scaling cycle : the dosage will depend on product used.
Example : Horolith C
- dose : 5 % per litre of water
- cycle length : 5-10 min at washing speed at 60 °C (140°F)
b) Carry out 2 cold rinses for 5 minutes at high level.
7
Clean the gas burners
Every six month
8
Check the tension and condition of the cage driving belts.
9
Check the connections of the electric elements (for electric heating).
10
Check the condition and fixing of the flexible steam pipe and clean the filter (for
steam heating).
11
Check the bellow's condition and the collar's squeezing.
12
Check the squeezing of the electrical connections on the main switch and the
electric heating contactor.
13
Check and clean if necessary the electrovalve's filters.
14
Scale the heating elements using the appropriate antiliming agent, and adapt the
frequency of these scales operations regarding to your real need.
15
Check the good running of the unbalance switch during an extraction : the machine
should stop when the switch is manually actionned.
16
Check the pipes' condition between the gas exchanger and the washer-extractor.
Every year
17
Sweep the smoke tubes of the heating box and the exhaust pipes of burnt gas (for
gas heating).
