Air Distribution Circuit - Vitrifrigo MACS Bedienungsanleitung

necessary to provide a manifold, to distribute the water to the condensers of the various
air conditioners. It is necessary that the manifold is equipped with water flow regulation
valves and the right diameter of water tube, to ensure the correct flow water to each
conditioning machine.

8. AIR DISTRIBUTION CIRCUIT

The air distribution system is the all the components that distribute the cooled or heated
air in the conditioned environment. The air distribution system must be designed, to
ensure correct air flow in the environment.
The machine is supplied with the fan with air outlet (Annex 4.1). The indications relating
to the installation of the various air distribution components are provided below.
Adjustable centrifugal fan: The air conditioner fan can be easily rotated, so you can
choose the easiest position of the air outlet. To facilitate the rotation of the fan, it is
recommended to perform it before positioning the air conditioner in its final location. To
rotate the fan, follow the instructions in annex 4.1 and 4.2.
Return air grille: The return air grille is the component of air distribution system that filter
and suction the air which must be cooled or heated (Annex 5.1, Fig. 5a).
For correct air distribution, the return air grille must be positioned at the bottom, at the
floor level, in front of the finned exchanger. We recommend keeping at least 10 cm. of
space between the grill and the exchanger itself.
Generally, the return air grilles are equipped with a filter. If this is not the case, it will be
necessary to install a filter in front of the evaporator.
ATTENTION Vitrifrigo return air grilles are equipped with a filter. If grilles other than
the Vitrifrigo accessory kit are used in which the air filter is not present, a filter must be
installed in front of evaporator or in the grille.
The air filter, whether present on the grille or installed separately, must be periodically
cleaned so as not to obstruct the flow of air towards the air conditioner.
Supply grill: The supply grille has the components that supply the conditioner air to the
room. The grille must have a surface that guarantees a good flow of air towards the
conditioned environment, without the speed of the air being excessive and therefore
constituting a source of annoyance for the people who occupy it.
For the correct air distribution, the supply grille must be positioned at the top, and its fins
must be oriented in such a way that the air outlet does not face directly towards the
return air grille (this would create a short circuit of the treated air) (Annex 5.1, fig. 5b).
