6.4 Removing and installing components for maintenance
6.4.1 Preparing the Condair RS for the removal of components
Before starting any removal work set the Condair RS out of operation and drain the steam cylinder and
the scale collector tank (if applicable). Proceed as follows:
1. Condair RS must be switched on. Perform a draining of the steam cylinder (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.
2. Set the steam humidier out of operation as described in chapter 4.5.
3. This step must be carried out only on units equipped with a scale collector tank:
• Place a sufcient large container (capacity of approx. 2.6 gal (10 litres)) below the scale collector
tank.
• Carefully open the drain valve on the bottom of the scale collector tank, then wait until no water
ows out of the drain valve.
WARNING!
Danger of burning!
The temperature of the water in the scale collector tank can be up to 203 °F (95 °C)
shortly after steam has been produced.
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 <122 °F (<50°C)
before dismantling the tank (since the scale collector tank is lled with water).
Note: On units equipped with the optional drain valve for the scale collector tank, close drain
valve on the scale collector tank and remove hose from the connector.
4. Wait until the temperature indication adhesive on the scale collector tank indicates a temperature
<122 °F (<50°C) (temperature eld on the temperature indication adhesive is green).
