9.4.1 Perform leakage check
Risk of electrical shock!
Hazardous electrical voltage!
Follow safety instructions for work on live
components.
Leakages may invoke leak currents.
The leakage check procedure outlined here-
after must be carried out following all mainte-
nace work relating to the water circuit within
the unit. When work has been done in sev-
eral areas, a final leakage check is sufficent
though this step is part of all of the relevant
particular partial work.
The leakage check procedure must be run
with the housing cover detached and with
special regard to the warning given above.
»
Open water supply.
»
Let unit run for 15 to 30 mins, then
check inner housing for leakages
(hose connections, o-rings, seals
and gaskets).
»
In case of leakage turn off power
supply and secure against being
switched on again.
»
Find leakage and eliminate.
»
Repeat leakage check until no
further water exit is detected.
9.5 Cylinder base and strainer
cleaning
»
Remove steam cylinder as descri-
bed in secton 9.4.
»
Remove cylinder base o-ring (13)
»
Lift strainer insert (12) out of the
base using the two access holes on
the side.
»
Remove all deposits from the coarse
strainer.
»
Keep coarse strainer clean with
mechanical utilities.
»
Check base for deposits and
remove if necessary. Especially the
passes of the hose connections
should be checked.
»
Insert coarse strainer and position
correctly by clicking the cut-out into
place in the clip.
»
Thoroughly clean o-ring seating in
cylinder base. No calcium residue
must remain on the seating.
»
Reinstall steam cylinder as descri-
bed in section 9.4.
9.6 Steam cylinder and heater
element cleaning
Risk of functional disruption!
Use descaler or cleaning detergents only for
cylinder and heater element cleaning. Do not
introduce in cylinder base or apply to hoses!
Prior to restarting the unit, make sure that the
device assemblies in question are thoroughly
flushed or rinsed.
»
Open cylinder clamping ring (7) and
lift off cover (5) with heater elements
(8).
»
Remove o-ring (15) and check.
HygroMatik recommends the
replacement of the o-ring (15) bet-
ween cylinder (9) and cylinder cover
(5) when reassembling the cylinder
»
Remove all deposits. Small amounts
of scale deposits on the heater ele-
ment(s) (8), however, are harmless.
