Installation
6. Installation
6.1 Prerequisites
This section is intended exclusively for the Installer.
Refer to the Technical data chapter for details.
Follow the safety instructions in the "About R-290 refrige-
rant" a pag. 8.
The electrical system and its components must be desi-
gned by a qualied technician who must work according
to the rules of good practice and national regulations.
If the unit is installed on a roof or terrace, check its load
capacity and the possibility of draining the condensate.
Ensure that:
• the location can be accessed safely
• the clearances are guaranteed
• a suitable place for condensate water discharge is avai-
lable nearby
• install the unit raised from the ground
• the location of the unit does not disturb neighbours
• the support surface or the wall can withstand the weight
of the unit
• the floor or wall section does not interfere with power
lines or water piping and no load-bearing elements of the
construction are compromised.
Avoid therefore:
• places that may be subject to flooding
• installations near bedrooms or windows
• snow accumulations obstructing air intake and exhaust
• obstacles to the airflow
• leaves or other foreign bodies that can obstruct the
exchange batteries
• winds that hinder or favour the airflow
• heat or pollution sources close to the unit (chimneys,
extractors, etc.)
• stratification (cold air that stagnates at the bottom)
• air circulation between supply and intake
• positioning in shafts and/or openings.
6.1.1 Windbreaks
Installing the unit in particularly windy areas may cause
operating problems:
• frontal wind exceeding 5 m/s causes short circuit pro-
blems between air supply and return and a decrease in
operational capacity
• frequent acceleration of the formation of ice
• Interruption of operation due to high or low pressure
alarm.
Ensure that:
• the unit is positioned so that the air supply is at 90° to the
wind direction.
When a strong and continuous wind blows against the
front of the unit, the fan may start to rotate very fast until
it breaks.
Provide windbreaks in front of the unit.
Do not install the unit in a location where the suction side
may be directly exposed to wind.
