If this drain pipe is not used, then the drain point in the bottom of the unit MUST be open. A grommet is supplied
in the packing bag to be installed in the bottom of the unit if an alternate drain location is used.
In order to prevent the formation of excessive condensate, you should nevertheless:
- check the seals on regular intervals
- consider installing a door contact switch (order no. 3100001). This will prevent condensation forming when
enclosure door is left open.
