1.3 General information
Every SPLIT LINE air conditioner consists of two
separate units:
1) CONDENSER UNIT which can be installed
outsidethevehicle,insidethedoublefloor,inside
thegarage orabenchor acabinet.The purpose
of this unit is to drive out hot air.
2) EVAPORATOR UNIT (or AERATOR) which
must be installed on the roof of the vehicle in
the place of a rooflight (40 x 40 cm) or else on
an aperture of the same size made in an area
of your choice on the roof itself. It has the
purpose of cooling the air inside the vehicle.
Both units are connected to each other by two very
thin hoses (6 and 10 mm). The hoses are
connected to the units by quick coupling joints
(which do not require any special tool).
AlltheSPLIT7000conditionershavebeendesigned
to be fed using 230 VAC 50 Hz current.
The feeding voltage must fall
within the range of 205 VAC and 250 VAC, the
steady frequency between 49 Hz and 51 Hz.
Usingthemachinewithothervoltagesorfrequencies
will be harmful to proper operation of the air
conditioner, and will invalidate the warranty.

4INSTALLATION
4.1 Preliminary information
Before installing the air
conditioner, you must by all means read these
instructions in order not to make any mistake
while installing.
Improper installation of the air
conditioners may lead to irreparable damage to
the equipment and compromise the safety of
the user.
Shouldthe airconditioners beinstalledin amanner
which does not comply with the instructions of this
manual, the Manufacturer shall not be held liable
forany failureor forthesafety ofthe airconditioner,
according to the law DM 89/392/EEC. The
Manufacturershallalso notbeliable,insuch acase,
for any damage to things or injury to people.
The unit must be installed
according to the national installation standards
(for Italy, it must be exclusively installed by
qualified and specially trained personnel).
4.2 Installation
Before installing, you must cut
off all the power supply to the vehicle
Battery positive pole
Generator unit (if any)
Outside power source.
Failure to comply with the
above instructions may lead to electrical
discharge.
Before getting onto the roof of
the vehicle, make sure it is strong enough to be
walked on. Check with the provider of the
vehicle. Should it not be strong enough, you
must set up a special trestle with scaffolding.

4.3 Installing the condenser unit
Condensing unit dimensions:
Height: 210 mm
Width: 363 mm (423mm with conveyor)
Length: 590 mm
When you install the condenser unit, remember it
must always have ventilation from the outside via
at least two openings Fig. 3 Ref. (1) and (2).
The condenser unit intakes air from the outside via
theopening Fig. 3 Ref. (1),then -after havingused
it to cool the condenser inside - it then exhausts
the hot air via the opening Fig. 3 Ref. (2).
Two kinds of installations can be made:

"A" type installation "B" type installation
4.3.1 "A" type installation
The condenser unit air intake is from the side and
the hot air exhausts from the bottom.
4.3.2 "B" type installation
The condenser unit air intake is from the bottom
and hot air outlet from the bottom also. This kind of
installation calls for greater attention, since it is of
theutmostimportancethat the hotairwhichisdriven
out is not sucked back in via the opening Fig. 3
Ref. (1), as this would diminish the efficiency of
the conditioner.

Should the condenser unit be installed outside the
vehicle,do notplacethe airinlethole againstawall,
whichcould limitthe passageof air.If the unitis too
close to the ground (less than 40 cm), the hot air
exhaustfrom Fig. 3 Ref. (2) -could besucked back
in again by the air intake Fig. 3 Ref. (1).
If you install the condenser unit inside the vehicle,
you must be careful to keep the flow of the inlet air
separate from that of the hot exhaust air, and also
prevent the hot exhaust air from getting inside the
vehicle.
To separate the two air flows, use a soft sponge
adhesive liner Fig. 4 Ref. (3), placing it against the
floor,in orderto preventthe hotair comingout from
Fig. 4 Ref. (2) beingsucked inthroughtheair intake
Fig. 4 Ref. (1).
After having prepared the area of installation of the
condenser unit, you should connect the gas pipes
and the extension cables, before finally fastening
the unit in place.

4.4 How to fasten the condenser unit
The condenser unit may be installed either
suspended on two brackets (not provided) on the
outside of the vehicle Fig. 9 Ref. (1), or resting on
the floor on the inside Fig. 9 Ref. (2).
Everyconditioner comesprovided with4 L-shaped
brackets and 4 silent-blocks Fig. 9 Ref. (3).
In order to avoid transmitting any vibrations from
thecondenserunittothefloor,itisimportanttofasten
the unit onto the silent-blocks.
NOTE:The condensingunit maybe installedin the
horizontal position Fig. 9 Ref. (2) but NOT in the
vertical position.

Always close the condensing
unit completely before starting the air
conditioner. If the conditioner is run with one
of the condensing unit lids open, the gas
pressure inside the pipes will continue to rise
and the 6 mm pipe will eventually burst.
Any breakages caused by failure to observe
this simple rule shall not be covered by the
warranty.

to Collection and Disposal Centres.
5.2 Opening a new hole
On the roof, chose an central area between two
stanchions and use a felt pen to mark off a square
measuring 400 mm on each side Fig. 11 Ref. (1).
Use a small saw to carefully cut the opening on the
roof. Be careful not to cut any electric wires Fig. 11
Ref. (2) . Wear goggles and safety
gloves before using any electrical/manual tools
or saws.
Placea reinforcingframe (Fig. 12) alongthe profile
of the opening; if necessary, drill a hole on the side
toletthrough thepowercablesand refrigeratinggas
pipes.
5.3 Positioning the evaporating unit
Before positioning the evaporating unit on the roof
of the vehicle, you must spread a proper amount of
slow-dryingsealantaroundtheedgesoftheopening.

6USER INSTRUCTIONS
6.1 Foreword
TheSPLIT 7000 air conditioner consistsoffourbasic
sections:
compressor: this makes the refrigerating gas
inside the system circulate and raises its tempera-
ture;
condenser: this cools the refrigerant, changing
its state from gaseous to liquid;
injector: this changes the state of the refrigerant
from liquid to gaseous;
evaporator: this receives the refrigerant in its
gaseous state, cooling the surrounding air. The
cooled air is spread inside the vehicle by a variable
speed fan.
The SPLIT 7000 airconditioner canprovidecool air
in summer and warm air in winter. Before starting
up the air conditioner - after a long period during
which the vehicle has been exposed to the sun - it
is good practice to open the doors and windows to
letoutthe heatwhichhasbeenaccumulating inside.
When the temperature inside the vehicle has
reached the same level as the outside temperatu-
re, close the doors and windows and start up the
air conditioning system, opening the doors and
windows only in case of need.
The equipment must be connected to the power
supplyincludedinthe sectioningdevicebyplugging
the three input leads coming out of the condensing
unit (Blue-neutral , Brown-phase wire , Yellow/
Green-earth) to the vehicle installation. The
sectioning device must have a separating distance
between contacts of at least 3mm.
The leads used must have a cross-section of at
least 2.5mm2 for a distance shorter than 5 metres.

SPLITSPLIT
SPLIT 7000
The air conditioner is provided
with an environment thermostat having a
minimum working temperature of 16°C.
Belowthis temperature, thethermostatdoesnot
enable operation of the compressor. This
prevents the risk of ice developing inside the
airconditioner;the fans and the heatingfunction
continue to be enabled.
To start up the air conditioner, put the ON-OFF
switch Fig. 20 Ref. (2) in its cool air position; then
turn the thermostat Fig. 20 Ref. (3) and set it at the
temperature you require.
The thermostat keeps the temperature of the air
insidethevehicleconstant,turningtheairconditioner
compressor (cool air) or the heating resistor (warm
air) on and off.
The speed of the fans is set by hand: use the
relevant selector Fig. 20 Ref. (1) .
To use the air conditioner more efficiently, we
suggest you proceed as follows:
First selectthe maximum ventilation speed with
thethermostat at minimum.
When youreachthe temperatureyou want,select
medium ventilation speed, then turn the
thermostat knob until the compressor goes off
For night time use, we suggest you use the
minimum ventilation speed.
6.4 Ventilation
Ifyou wantto circulateair insidethevehicle without
heating or cooling, proceed as follows.
Put the CoolAir / Hot Air selector Fig. 20 Ref. (2)
in the position
Select ventilation speed ( ) you want
Fig. 20 Ref. (1).
Set the thermostat Fig. 20 Ref. (3) at maximum
temperature (35°C).
6.5 Heating
The electric heater of the air conditioner is no
replacement for the boiler heating system, but it is
good for warming the air in the morning or in cool
days.
Put the CoolAir / HotAir selector
in the position
Set the thermostat Fig. 20 Ref. (3) at the
temperature you require.

6.6 Turning off
To turn the air conditioner off, set the switch Fig. 20
Ref. (2) at the position "0".
After turning off the air
conditioner, using the thermostat knob or else
the ON-OFF switch, you must wait at least 3
minutes before turning it back on again, in order
to allow the refrigerant to stabilize its pressure.
Failure to comply with this rule may lead to
irreparable damage to the compressor of the
air conditioner and render the warranty null and
void..
6.7 Safety rules
Always use power sockets which are connected
to earth and are protected by differential cut-off
switches.
Never use the air conditioner near flammable
liquids.
Neveruse theairconditionerforany purposeother
than those provided for by the Manufacturer.
Do not modify or tamper with any part of the air
conditioner.
Use original spare parts.
Maintenance and repairs must be carried out by
specialized personnel.
Installation must be carried out by specialized
personnel.
Do not put your hands inside the ventilation grids.
Do not put any foreign matter into the ventilation
outlets.
Should the air conditioner suffer from any forceful
impact, have specialized technicians check it out
before using it again.
In case of fire, never open the top lid of the air
conditioner,butuseapprovedtypefireextinguishers.
Do not use water to put out fire.
6.8 Troubleshooting
Iftheairconditionerfailstoworkproperly,thisusually
will not be due to a fault but simply to improper use.
For example:
The airconditioner isundersized comparedto the
volume of air to be conditioned.
The walls of the vehicle are not sufficiently
insulated.
The doors are opened too frequently.
There are too many people inside the vehicle.
The voltage is less than 205 V.
Followingis alistof possibleproblems, whichcould
be encountered, their reasons and how to solve
them.
If the air conditioner is working
poorly, first make sure:
That the power supply is never less than 205 V;
The suction filters are not jammed;
The air diffusion outlets are open;
1) The air conditioner fails to start up:
• make sure that the cool air / warm air switch Fig. 20
Ref. (2) is not in "0" position and that the thermostat is in
its all-cool position Fig. 20 Ref. (3) .
• Then make sure that the sockets are powered,

In order to ensure proper efficiency of the air
conditioner, once a year you must carry out a
thorough cleaning of the condenser, or have a
technician carry it out.
