1.4 -- Vertical flow positioning (standard) (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.
NOTE: If a vertical height of 4m cannot be guaranteed, duct
the unit (para. 1.5) or position it vertically (para. 1.6).
Legs are supplied as standard.
1.5 -- Vertical flow positioning with expulsion duct
(Fig. 2)
S Fig. 2 shows a typical example of a ducted unit.
S The Service Area in Fig. 1 must be respected, except for
the vertical height.
NOTE: Ducting not supplied by us
1.6 -- Horizontal flow positioning (Fig. 3)
The condenser can be vertically positioned as described.
ATTENTION: ALWAYS POSITION THE CONDENSER SO
THAT THE REFRIGERANT ENTERS FROM THE TOP AND
