INSTALLATION SITE.
• e unit is supplied with ammable refrigerant and must be installed in a properly ventilated place. If the appliance is
installed indoors, an additional refrigerant detection device must be added in addition to a further ventilation appliance
pursuant to standard EN378. Make sure to take adequate measures so that the unit is not used to house small animals.
• Animals that come into contact with electric components could cause operating failures, smoke or re. Please advise
the customer to keep the area around the unit clean.
WARNING
• Choose an installation site where the following conditions are met and which is approved by the customer.
- Well ventilated places.
- Places where the unit does not bother neighbours.
- Safe places that can bear the weight and vibrations of the unit and where it can be installed on a at surface.
- Places where ammable gas or ammable product leaks are not possible.
- e appliance is not intended to be used in potentially explosive atmospheres.
- Places where clearance for maintenance can be guaranteed.
- Places where the pipes and lengths of the wiring of the units are within the admissible limits.
- Places where the water escaping the appliance cannot damage the environment (e.g. in case of blocked drain pipe).
- Places where rain can be prevented as far as possible.
- Do not install the unit in places which are oen used as workspace. In case of construction work (for example grinding,
etc.) which creates lots of dust, the appliance must be covered.
- Do not place any object or equipment above the unit (top plate).
- Do not climb, sit or stand on the unit.
- Make sure that sucient precautions are taken in case of refrigerant leaks according to local laws and regulations on the
matter.
- Do not install the unit near the sea or in the presence of corrosive gas.
• When the unit is installed in a place exposed to strong wind, pay particular attention to the following.
Strong winds 5 m/sec or more that blow against the air outlet of the unit cause a short circuit (suction of exhaust air)
which could have the following consequences.
- Deterioration of operating capacity.
- Frequent acceleration of icing in heating mode.
- Interruption of operation due to the high pressure increase.
- When a strong wind continuously blows on the front of the unit, the fan can begin to spin so quickly that it breaks.
Under normal conditions, refer to the following gures for installation of the units 4-16 kW:
A
Unit A
4-6 kW ≥300 mm
8-16 kW ≥300 mm

If there is strong wind and its direction can be foreseen, refer to the gures below for installation of the unit (any of them
will do).
Turn the outlet side of the air towards the wall of the building, fence or screen.
B
Unit B
4-6 kW ≥1000 mm
8-16 kW ≥1500 mm
Make sure there is sucient space for installation.
Arrange the outlet side at a right angle with respect to the wind direction.
• Prepare a water discharge channel around the foundation, to drain the water around the unit.
• If the water has diculty owing out of the unit, mount the unit on a cement block foundation, etc. (approximately 100
mm (3.93 in) high).
• If the unit is installed on a frame, assemble a waterproof plate (about 100 mm) on the lower side of the unit to prevent
the water from entering from below.
• When the unit is installed in a place frequently exposed to snow, please pay particular attention to raise the foundation
as high as possible.
Under normal conditions, refer to the following gures for installation of the units 18-30 kW:
＞300 mm
