Siphon height

Δp - maximum positive / negative working pressure in the compartment of the unit. The height of

condensate drain pipe h = 15 cm is sufficient for vast majority of installations.

●

Connect one siphon trap (included in delivery) to each condensate outlet. Connect the siphon to the

sewer line.

●

Make sure that the condensate pipe is passible all the way along including parts inside the unit and

the pipe slope is sufficient.

●

Fill each siphon trap with water.

Installing air filters

The unit is supplied with separately packed filter cassettes. Various filtration classes can be selected

for filters of outdoor, extracted and circulation air: ISO Coarse 60% (G4), ISO ePM10 50% (M5), and

ISO ePM1 55% (F7). Example of filter installation:

Filter with class ISO ePM1 55% (F7) as outdoor air filter, location in the compartment e1 (ODA);

Filter with class ISO ePM10 50% (M5) as extracted air filter, location in the compartment i1 (ETA).

Filter with class ISO ePM10 50% (M5) as circulation air filter, location in the compartment c1 (IDA).

●

Remove, unpack the cassettes and check their condition. Then install the cassettes in their correct

location based on the unit orientation, see description of the unit in the Chapter 3.1.



Unpack and install air filters last, immediately before putting the unit into service to avoid their

contamination.

●

Should any damage or contamination be detected, replace the filters with new ones. Spare filter

cassettes are to be ordered from the supplier. The supplier´s address and the spare cassette part

number are shown on the identification plate of the unit.

●

Insert undamaged clean filters into the guide rails and secure them.

Especially make sure that the arrow showing the direction of air flow through the filter cassette can

be seen from the side of the operator (the arrow is by the unit´s door);

Filter of outdoor air e1(ODA) and extracted air i1(ETA) – the arrow points towards heat
