4.6 Taking the unit out of operation
In order to take the Condair RM steam humidier out of operation (e.g. for maintenance purpose), per-
form the following steps:
1. If maintenance work on the water system of the Condair RM is to be carried out, the steam tank
must be emptied. Proceed as follows:
a. Switch off the Condair RM via the unit switch.
b. Wait 5 seconds, then switch the Condair RM on again. If the drain pump starts, wait 60 seconds
until the steam tank has been emptied. If the drain pump does not start automatically within 10
seconds (e.g. because of a pump failure), drain the steam tank manually via the manual drain
hose (see step 5).
2. Close the shut-off valve in the water supply line.
3. Switch off the Condair RM via the unit switch (if not yet switched off).
4. Disconnect Condair RM from the mains: Switch off the electrical isolator in the mains supply line
and secure switch in "Off" position against accidentally being switched on, or clearly mark the switch.
5. If you have to carry out work on the water system: Loosen the retaining screw on the unit cover,
remove the unit cover, then drain (residual) water from the steam tank into an empty bucket via the
manual drain hose (position of the drain hose, see Fig. 2).
WARNING!
Danger of burning!
The water in the steam tank can be hot (up to 95 °C). There is danger of burning when
draining the steam tank via the manual drain hose shortly after steam has been produced.
Prevention: wear isolating gloves and be careful when draining the water via the manual drain hose.
