4.4 - Vertical flow positioning (Fig. 1)
In order to allow sufficient air flow through the unit and space for
any eventual maintenance, the Service Area should be left free of
obstructions.
The Service Area in Fig. 1 must be respected.
With vertical airflow installation a free area of at least 4 m above
the condenser has to be guarantee for a correct air circulation with
the aim to avoid air short-cut from discharge to suction air side of
condenser.
Legs of unit are supplied as standard and they need to be mounted
at full length for a correct working of unit.
4.5 - Horizontal flow positioning (Fig. 2)
The condenser can be positioned for horizontal air flow.
The Service Area in Fig. 2 must be respected.
