4.4.5 PerformingacompleteushingoftheCondairRO-Asystem
Note: the FWA ushing function in the "manual" submenu appears only, if the Condair RS is connected
to a Condair RO-A reverse osmosis system and if the reverse osmosis system was activated in the
factory menu.
To perform a complete ushing of the RO system proceed as follows:
1. Press on the <Drain> button in the standard operating display. The "Manual" submenu appears.
2. Press on the <FWA> button in the "Manual" submenu.
3. Press on the <Yes> button to start the ushing of the complete system. The progress bar in the
display shows the current status of the ush cycle. After ushing has nished the unit returns to the
"Manual" submenu.
Note: in order to stop the ush cycle press the <Cancel> button in the draining progress window.
The ush cycle is stopped and the unit returns to normal operating mode.
4.5 Taking the unit out of operation
In order to take the Condair RS steam humidier out of operation (e.g. for maintenance purpose), per-
form the following steps:
1. Close the shut-off valve in the water supply line.
2. If you have to carry out maintenance work on the steam cylinder and/or on the scale collector tank
perform a cylinder draining (see chapter 4.4.3).
Note: On units equipped with the optional drain valve for the scale collector tank, the scale collector
tank is drained simultaneously when performing a draining of the steam cylinder.
3. Switch off unit switch of the steam humidier.
4. Disconnect steamhumidierfromthemains: Switch off both electrical isolators in the mains
supply lines (heating and control voltage) and secure switches in "Off" position against accidentally
being switched on, or clearly mark the switches.
5. If you have to carry out maintenance work on the steam cylinder, empty the scale collector tank via
the drain valve.
WARNING!
Danger of burning!
The temperature of the water in the scale collector tank can be up to 95 °C.
Therefore: wear isolating gloves and open the drain valve carefully.
If no water ows out from the open drain valve, the drain inside the scale collector tank is clogged and
the scale collector tank may not be emptied. If this is the case, wait until the temperature indication
adhesive on the scale collector tank indicates a temperature below "<50°C" before dismantling the
tank (since the scale collector tank is lled with water).
