General description
General
This dry cooler is designed for outdoor location and is intended for refrigerants that are
not aggressive in contact with copper.
The cooler conforms to environment class 3.
The cooler is provided with axial fans and the casing is made of aluminium sheeting as
standard.
Important
Do not allow the product to be covered by foreign objects when in operation.
Unobstructed circulation of air is necessary to achieve the highest cooling efficiency.
The laminar surfaces of the battery must be free of deposits.

Installation
The following instructions for installation should be read together with the technical
leaflet.
Location
Place the cooler so that air can pass freely over the entire battery surface and if
possible so that the wind direction does not affect the evacuation air because
re-circulation could otherwise occur. This applies particularly to models
that have low revs.
The cooler is to be mounted on a firm base and secured with foundation bolts.
The cooler frame is provided with pre-drilled holes.
