IMPORTANT
Installation requires an experienced mechanic with specific knowledge in the installation of
the VIESA Ecological Cooler. Installation, disassembly, repairs and maintenance
must be performed by an Authorized Installer. Authorized Installer must use proper
protective equipment when installing the system.
Improper installation or use of unauthorized parts can cause malfunctions, loss of battery life
or other consequences which may result in serious injury.
Manufacturer or Distributor will not be responsible for injuries or damages resulting from
misuse of equipment, use contrary to operating instructions or installation by any person
other than an Authorized Installer.
Information contained in this manual is subject to change. Manufacturer reserves the right,
without notice, to make changes in equipment design or components as progress in
engineering, manufacturing or technology may warrant.

1- ECOLOGICAL COOLER
Operation
Application
Applied to any unit with an operating voltage of 12 V and
Cooling is generated by vaporized cool water delivered by a self-contained
electrical motor. During operation it only consumes water and it makes no use of
internal combustion engines, nor does it use chemical coolants or emit gases into
the atmosphere. The unit is equipped with a water pump located in an auxiliary
tank which takes water to the evaporator. A biturbo blower pushes the exterior
air to the interior of the vehicle forcing the air through the evaporator and
therefore cooling the warm air. The exceeding water backs to the water tank.
Function
VIESA Agro is a roof mounted cab cooler that delivers cool air to the vehicle's
cabin using evaporative cooling and without running the vehicle's engine.

Viesa Agro is not to be installed to agricultural equipment

a.3) Check from the inside that no reinforcement channels or electrical wires will be cut.
a.4) Cut the roof and shave any roughness.
Note: When cutting, be carefull not to make right angles on the
the corners. Corners must be round (see detail) in order to avoid
future roof fissures.
Important: If the roof surface is a thin metal sheet,
a 1cm. fold upwards has to be made all around the perimeter.
