5.4. Identification of ports
Identify and label individual ports using the pictures below (labels are included). Begin by identifying
port e1 (ODA) - outdoor air inlet; continue toward the fan on the same (shorter) side of the unit with
exhaust air outlet port i2 (EHA); next is the port with fan on the opposite side of the unit - supply air
outlet e2 (SUP); the last (remaining) port is extract air inlet port i1 (ETA).
Note
: Depending on a specific location of the unit proceed clockwise or anticlockwise.

Only units up to size 1600 can be adjusted that way.
