At the return air suction from behind the air duct has
to be fixed at the back with M8 screws. In this case
the standard filter can not be used. A special filter
has to be installed in the air duct, instead.

12.3 Air Circuit Options
EU5 filter (only for size 2)
The EU5 filter is used instead of the standard EU4 filter and cuts down on air contamination to a greater extent.
Condensate pump
The condensate pump is delivered lose.
The type of pump depends on the A/C unit equipment.
without steam humidifier: condensate pump type AB-1 F/M, March
with steam humidifier: condensate pump type A2-SA, Milton Roy Hartell
The condensate pump extracts the condensate water occurring in the condensate water tray and pumps it into the
local sewage system. The condensate water tray is located beneath the filter elements in the A/C unit. The pump is
provided with an integral float switch. The float switch switches the pump on and off automatically.
Connect the 6 m long drain hose (6 mm diameter) to the local sewage system.
Connect the pump in accordance with the terminal diagram.
When routing the drain line, ensure that it is not kinked.
