Discharge
plenum
(option 203.3) (figure 8)
The discharge plenum is designed to be
installed on top of the VCH series. When
ordered with this option, the unit is delivered
without top plate so that the discharge
plenum can easily be pushed in the top
outlet of the unit. A plastic bag contains the
needed fixing screws (qty 12 for the sizes
100 & 150 / qty 14 for the size 200 & 300 /
qty 16 for the sizes 400 & 500 / qty 16 for
the sizes 600 & 700 and qty 18 for the sizes
800 & 1000) (see fig. 8).
The horizontal louvres may be adjusted to
obtain proper deflection and air pattern.
For safety reasons, it is recommended to
wear gloves and glasses when adjusting the
louvres.

4.4.3
Vertical louvres
(option 207.1) (fig. 9)
The discharge plenum (option 203.3) can
be equipped with vertical louvres thus
enabling a horizontal deflection of the air
(max.
!
150°). The vertical louvre frame
must be securely screwed in the openings
(outlets) foreseen in the bottom and upper
side of the plenum.
When adjusting the vertical louvres wear
gloves and glasses.
Closing all the vertical louvres at a time is
forbidden as this could result into an air
obstruction influencing the LC3 (maximum
temperature thermostat).
The number of vertical louvre assemblies, the
vertical louvres and the fixing screws vary per
model :
