Regulations for environmental safety and correct disposal
All organisations must apply a set of procedures to identify, evaluate and control the influence that their activities (manufacturing, products, services,
etc.) have on the environment.
The procedures to be followed to identify significant environmental impact must take the following factors into account:
- use of raw materials and natural resources
- atmospheric emissions
- discharge of liquids
- waste management and recycling
- contamination of the soil
In order to minimise environmental impact, the manufacturer provides a series of indications here below that should be taken into account by all those
who, for whatever reason, interact with the appliance during its working life.
- all packing components must be disposed of (preferably recycled) in compliance with statutory legislation in the country in which disposal
takes place
- all product components must be disposed of (preferably recycled) in compliance with statutory legislation in the country in which disposal
takes place
- for correct disposal, the appliance must be consigned to an authorised waste disposal company to ensure that all recyclable components
are reused and the remaining materials are processed properly
- during installation ensure the room has adequate ventilation to prevent the build-up of stale air that might be harmful to the health of the
operators
- during operation and maintenance ensure that any waste pollutant products
(oil, grease, etc.) are disposed of correctly
- keep noise levels down to reduce noise pollution
For more information on correct dismantling of our products please refer to the recycling handbooks at www.dometic.com/ambiente.........

1.1. Scope of the manual
This manual has been made by the Manufacturer and it shall be regarded
as part of the air conditioner.
The information it contains, when complied with, ensures a correct and
efficient use of the air conditioner.
The first part of this manual is for users , the second one for qualified
technicians facing the installation of the air conditioner.
To draw the readers attention to special parts of the text, the following
symbols have been used:
This operation may result in dangers

1.2. Manufacturer and air conditioner data plate
1.3. Description of the air conditioner
This air conditioner has been designed and manufactured to be installed
onto vehicles (i.e. camping-cars, caravans, motorhomes) to improve the
temperature conditions. It supplies fresh and dehumidified air in summer
and warm air in winter without, in any case, replacing the heating system
of the vehicle. In both cases, temperature is set by the user.
Fresh air - Running
The system is inclusive of: compressor ( a ), condenser ( b ), evapora-
tor ( d ) and refrigerant gas under pressure. According to the physical
state of the refrigerant gas -i.e. liquid or gaseous, it heats or cools the
components where it passes through.
Fan ( c ) forces the internal air through the cooled evaporator from where
it comes out cooled down and dehumidified.
This action, protracted over the time, reduces the temperature into
the vehicle.
Hot air – Description of operation
The refrigerant gas cycle can be inverted by a solenoid valve (f). The
heat accumulated by the refrigerant gas is dispersed by the internal
heat exchanger which uses the fan (c) to deliver the heat into the
passenger compartment. Over time, this increases the temperature
inside the vehicle.

1.4. How to use the air conditioner
The air conditioner performance can be improved by taking some
simple measures.
Improve the thermal insulation of the vehicle by closing any opening
and by covering any glassed surfaces with reflecting curtains.
Avoid opening doors and windows unnecessarily.
Select the most suitable temperature and speed.
Properly direct the air flaps.
To prevent troubles and minimise risks for people, take the following
precautions:
Do not obstruct the air inlets and outlets with cloths, paper or other
objects;
Do not introduce your hands or other objects into the openings;
Do not spray the air conditioner with water;
Keep flammable substances away from the air conditioner.

anticlockwise, to choose the wished position and then rotate clockwise.

To install the air conditioner, the roof shall have an opening of suit-
able sizes. It is possible to use an existing air inlet or make a new
one.
According to the vehicle dimensions and depending on the air
conditioning needs, one or more units can be installed. The air
conditioner must be installed right in the middle with respect to the
vehicle Width and length.
Before installing the unit, make sure that the opening does not
interfere with the existing furnishing (lamps, wardrobes, doors,
curtains, etc.). This check allows for an easy mounting of the air
conditioner and a troublefree air circulation.
contact the vehicle manufacturer and make sure that the
roof structure can tolerate the static load and the stress tran-
smitted vehicle, especially under running conditions. Some-
times vehicle manufacturers previously arrange areas for the
unit installation weakening and/or electric cable from being
cut.
The air conditioner should preferably be installed on a
level plane. Maximum allowed inclination: 10°.
