5.3.3  Refilling / Replacement __________________________________________________________ 

Lamp 

WATER“, indicating lack of water 

The light of lamp "WATER" shows that the amount 
of water in the reservoir is not sufficient any more. 
With this lamp on, there is no possibility to start a 
program. The reservoir has to be refilled with aqua 
dest/aqua dem until the lamp goes out. The 
maximum level is reached with the lower edge of the 
trapezi-form filling nozzle. 
If lamp "WATER" comes on after a start of a process 
and during pumping, it has no influence on running 

the program. 
The remaining amount of water in the water storage 
tank is in any case sufficient for the started 
sterilisation or disinfection cycle to run to completion. 

Replacement in case of pollution 

If dirt has come into the water reservoir because of 
misoperation, the reservoir has to be rinsed and 
cleaned, e.g. with a bottle brush. In every case, let 
off the water as described above and refill the 
reservoir. 

Putting out of operation / Transport 

 

 

Switch off main switch. 

 

Pull out main plug, let autoclave cool down. 

  Remove hose to condenser container from 

autoclave by pressing hard against the black 
ring of the connector (16) and pulling the hose 
out of the connector at the same time.

  Empty water reservoir as described in 

chapter 5.3.2. 

 If possible, 

use the original packing 

to 

transport the autoclave. Be sure in any case to 
additionally seal the autoclave inside plastic 
wrapping, in order to prevent packing material 
from entering the water storage tank, etc. 

6.1 

Transport under danger of frost ____________________________________________

 

If freezing temperatures are possible during 
transport, any water which may remain in the feed-
water system must be removed in order to prevent 
damage to the pump and the water lines. A service 
technician is required for this work, which includes 
the following steps: 

  The autoclave must be switched on and 

preheated. 

  Empty the water storage tank as described in 

Section 5.3.2. 

  Remove the metal side-enclosure panels from 

the autoclave. 

 

At the bottom left on the electronic circuit board 
there are four wire-clasp buttons / switches (22). 
The second from the bottom is the Test Button, 
which sets all outputs of the control system. 
Press this Test Button for the electronic control 
system until no more water is pumped on the 
output side of the water pump (through the thin, 
transparent hose). 

  Open and close the sliding door several times 

until all the water remaining in the steam 
generator is expelled. This action will heat the air 
contained in the preheated pressure chamber, 
which will cause the air to expand and expel any 
water remaining into the condensor container. 

  Switch off the power switch and unplug the 

power cable. 

  Replace the metal side-enclosure panels on the 

autoclave. 

  Disconnect hose to condenser container from the 

autoclave by pressing hard against the black ring 
of the autoclave's connector; at the same time 
pull the hose. 

  Let the autoclave cool down. 

Breakdowns without warning light 

 

The following instructions for breakdowns are pro-
vided to help the user resolve minor trouble himself, 
or to allow him a more accurate description of 
malfunctions to his authorized dealer, warehouse 
agent, or customer-service representative.  

Bigger faults or damages are repaired only by 
appointed service engineers or by the manu-
facturer.
