NEW PUMP SWITCH SINCE 06/2007

In the past time, it happened repeatedly that the pump switch of the gas conditioning system CSS-M..
failed. For that reason, we changed the switch in 06/2007 into a key button. The effect is that the
switch status of the pump in case of a voltage loss does not exist any more.
In order to keep the switch status, there is a jumper JP1 on the board by which you can determine
whether the pump shall restart automatically after a voltage loss or not.
With the bridge 2-3 (on), the pump restarts automatically.
With the bridge 1-2 (off), the pump does not restart again.
When delivered, the bridge is made between 1-2 (off), i.e. the pump does not restart after a voltage
loss.

CLOSING DOWN

The location for the gas conditioning unit must remain frost-free, even if the
unit has been switched off.
N O T E !
There are no special regulations to be observed if the gas conditioning unit CSS-M/W is to be closed
down for a short period of time.
In case of a long-term closing down, for example after a series of measurements has been completed,
it is recommended to purge the gas conditioning system with ambient air or inert gas. Under normal
conditions, the equipment needs only to be washed for 3 to 5 minutes. Condensate residues should
also be removed from the system.
