GENERAL RECOMMENDATIONS

BASIC SAFETY RULES

After having removed the packing, check that the con­tents are intact and complete.In the event of non-com-

pliance, contact the Agency which sold you
the appliance.

appliances should be installed by a qualified
company in accordance with the laws and regulations
in force in the country of installation. Upon completion
of work this company should issue the owner the
declar

ation

of compliance of installation with current

regulations and standards and with the instructions
given by in this booklet.

These appliances have been designed to heat or cool
the air of rooms and should only be used for this pur­pose in compatibility with their performance characte­ristics.

Under no circumstances can be held liable
for damage caused to property or injury to persons or
animals due to incorrect installation, regulation and
maintenance or to improper use.

Too low a temperature is harmful to health as well as
being a useless waste of energy.
Avoid prolonged direct contact with the flow of air.
Avoid the room being closed for a long time.
Periodically open the windows to ensure a correct
change of air.
During storms put the installation on/off switch to "off".

This instruction booklet is an integral part of the
appliance and should therefore be carefully preserved
and ALWAYS accompany the appliance, also in the
event of transfer to another owner or user or into
another installation.
Should the booklet be damaged or lost, request a

copy from the Area Service Centre.
Repair or maintenance work must be carried out by

the Service Centre or by qualified personnel
in accordance with instructions given in this booklet.
Do not alter or tamper with the appliance, since hazar­dous situations could be created and the manufacturer

of the appliance will not be liable for any damage or
injury caused.

The unit should be installed in compliance with local
installation and safety regulations.

For any repairs, contact only customer service centres
authorised by the manufacturer. Repairs made by
unauthorised personnel may be dangerous.

The CP20 ARE 290 air conditioner must be used and
stored in rooms with a volume of over 31 cubic
metres.

The CP30-CF30 ARE 290 air conditioner must be
used and stored in rooms with a volume of over 53
cubic metres.

The CF40 ARE 290 air conditioner must be used and
stored in rooms with a volume of over 53 cubic
metres.

Non-ventilated environments where an appliance con­taining flammable refrigerant is used must be compati­ble, to avoid the possibility of a gas leak reaching a
level of concentration such as to cause a fire or explo­sion resulting from the presence of other heat sources
(electric heaters, stoves or similar units).

The R 290 refrigerant charge is highly flammable, and
could cause an explosion in the event of leaks occur­ring in closed or poorly-ventilated areas. This gas is
heavier than air and invisible, but it generates a mist if
there is humidity in the air.
Avoid contact of the liquefied gas with eyes or skin as
it could cause injuries.

Transportation, charging, cleaning, recovery and dispo­sal of the refrigerant should be carried out only by
customer service centres authorised by the manufactu­rer.
Disposal of the appliance should be carried out only by
specialised personnel authorised by the manufacturer.

Using electrically-operated products implies the observance
of certain basic safety rules, such as those given below:

Children and unassisted handicapped persons are not
allowed to use the air-conditioner.
Do not touch the air-conditioner when barefoot or parts
of the body are wet or damp.
Do not carry out any cleaning operation until the air­conditioner has been disconnected from the mains
electricity supply by putting the installation on/off swit­ch to "off".
Do not alter the safety or regulating devices without the
permission and instructions of the manufacturer of the
air-conditioner.
Do not pull, detach or twist the electric cables connec-

ted to the air-conditioner, even if disconnected from the
mains electricity supply.
Do not sit or stand on the appliance or rest anything at
all on top of it.
Do not spray or throw water directly onto the air-condi­tioner.
Do not introduce sharp, pointed objects through the air
intake or outlet grilles
Do not access internal parts of the air-conditioner
without having first put the on/off switch to "off".
Do not leave the packing material (cardboard, staples,
plastic bags, etc.) within reach of children, but dispose
of properly since it is a potential source of danger.

RECOMMENDATIONS

Extraordinary maintenance

Programmed maintenance always represents a saving in
the running of the installation as well as preventing possible
faults.
To ensure trouble-free operation of the air-conditioner, it is
recommended that it be inspected at least once a year,
carrying out the following checks:

- cleanliness of the heat exchange coils of both units

Exposure control/personal protection

Use protective clothes and suitable gloves; protect eyes and
face.

Handling

Avoid inhaling high concentrations of vapors.
The atmospheric concentrations should be reduced to a
minimum and kept below the professional exposure limit.
The vapors are heavier than air and high concentrations
may therefore form near to the ground, where general venti­lation is poor. Under such circumstances, ensure there is
adequate ventilation.
Avoid contact with naked flames and hot surfaces, otherwise
irritating and toxic decomposition products could form. Avoid
the liquid from coming into contact with eyes or skin.

Precautions to take in the event of accidental spillage

Ensure adequate personal protection (using protective
breathing equipment) during elimination of spillage. If condi­tions are sufficiently safe, isolate the source of the leak.With
small leaks or spills and provided there is adequate ventila­tion, let the material evaporate.With copious leaks or spills,
adequately ventilate the area; keep the material from expan­ding using sand, earth or other suitable absorbent material.
Prevent the liquid from entering into drains, sewers, cellars
or work holes, since the vapors could create a suffocating
atmosphere.

First aid measures
Inhalation

- Remove the casualty from the area of exposure and
keep him/her warm and still.
Ask for immediate medical aid.

Contact with the skin

- Thaw the involved parts with water. Remove contamina­ted clothes, which could stick to the skin in the event of
cold burns. In the event of contact with the skin, imme­diately rinse with abundant lukewarm water. Should
there be symptoms of irritation or blisters, ask for medi­cal aid.

Contact with the eyes

- Bathe immediately with an eyewash solution or clean
water, keeping the eyelids wide apart for at least ten
minutes.Ask for medical aid.

Swallowing

- Do not provoke vomiting. If the casualty is conscious,
make him/her rinse out his/her mouth with water and
drink 200-300 ml of water. Ask for immediate medical
aid.

Other medical care

- Symptomatic and back-up treatment as required. Do not
administer adrenaline or similar sympathomimetic medi­cines following exposure, due to the risk of cardiac
arrhythmia.

ATTENTION

For further information on the characteristics of the refrige­rant fluid, refer to the safety data sheets available c/o the
refrigerant manufacturers.

QUICK CONNECTOR

I

BASIC OPERATION

The fast connector coupling uses a retractable sleeve and
stem valve on the female half and a spring loaded poppet
on the male side to create a safe, clean and quick

separation of split air condotioning system with minimal fluid
loss and air inclusion (see Figure 1).

CONNECTION OF THE UNIT

English

I

Fig. 2

Fig. 3 Fig. 4

TO CONNECT

- With the coupling handle in the “full back” position (Figure

5), retract the release sleeve on the female and insert

the
male half into the coupling. Make sure the inser tion tab on
the male half lines up with the slot on the female

body (see

Figure 5).

- Realease the retractable sleeve to lock the halves together
and tug gently on the halves to ensure locking has taken
place (Figure 3).

- Rotate the coupling handle towards the male half to open
the coupling. Make sure the handle bottoms on the

coupling body and the locking pin (on models equipped
with spring loaded locking pins) “pops”into the handle hole
properly (see Figure 4).

- Connect the auxiliary electrical and condensate lines, if
applicable.

- Connect the male and female caps together, if provided,
to keep them clean while the unit is in operation and

they

are disconnected from their appropriate halves.

- Connect unit to power outlet and start the unit.

Fig. 5

No tools are required to connect the coupling: a retractable
sleeve and four latch pins hold the male and female halves
together. The coupling valves open when the handle is

pushed forward and locked into place, and shut when the
handle is in the “full back”position (see figures 3-4).

English

TO DISCONNECT

- Shut off the air conditioning unit and unplug the unit from
the power outlet.

- Wait five minutes for line pressures to equalize.

- Disconnect the auxiliar y electrical and condensate lines, if
applicable.

- On couplings equipped with spring loaded locking pins,
depress the pin until it clears the coupling handle is pulled
up. When the handle clears the locking pin, pull coupling
handle to its “full back”position (see Figure 3).

- Retract the spring loaded release sleeve on the female
and remove the male half (see Figure 5).

- Install the caps on both halves, if provided. Close the
handle on female half after installing the cap.

DO’S AND DON’T’S

- Thoroughly check the coupling for proper position of seal
(see Figure 1), missing seals, leaking valves, debris,
proper mounting, or other damage prior to reinstalling and
restarting the air conditioner. Don’t use a damaged
coupling.

- Always keep the couplings connected even when the
system is not in use in order to minimize refrigerant
effusion, coupling damage and the entry of dirt or other
foreign material. If it is not possible to keep the
couplings connected, then both halves should be capped

immediatly upon disconnection with the optional caps as
shows in Figures 6 & 7

.

- Don’t tamper with the valves while disconnected or allow
children access to disconnected couplings.

- Don’t drop coupling half on any hard surfaces. The male
half is made of brass and if allowed to drop may become
d

amaged beyond the point where it can be reconnected.
Installing caps immediatly after disconnection will
minimize the possibility of damage if dropped.

- Do not open the coupling handle while the air conditioning
unit is operating.After shutting off the air conditioning

unit,
wait five minutes before opening the coupling in order to
equalize line pressures. Opening the coupling during
airconditioner operation may damage the compressor

Recommended installation height is between 1.80 and 2.40 m from the ground.

The place of installation should be established by the instal­lation designer or by a technically competent person and
should take into account technical requirements as well as
relevant current laws and regulations, which envisage the
obtaining of specific permits (e.g. town-planning, architectu­ral, fire, environmental pollution regulations, etc.); it is the­refore advisable to apply for and obtain the necessary per­mits prior to installing the air-conditioner.

The air-conditioner should be installed by a qualified com­pany in accordance with relevant laws and regulations in
force in the country of installation.

Before commencing installation, establish the position of the
indoor and the outdoor unit, taking into consideration the
minimum technical spaces, maximum length of the refrige­rant lines and the difference in level between the applian­ces.

The indoor unit should be wall-mounted.
It should be positioned so that the treated air may circulate
freely throughout the whole room, while observing the mini-

mum spaces necessary for technical and maintenance ope­rations.

Water connections

Prior to installing the air-conditioner, decide the direction of
the outlet pipes; they may be arranged in any of the five
directions indicated in Fig.(8):

1. to rear right

2. to right

3. downwards

4. to left

5. to rear left

Positioning the fixing plate

- Remove the steel fixing plate on the unit back

- Rest the cardboard reference template, supplied in the kit,
against the wall

- Position the steel fixing plate in the area outlined by the
cardboard reference template

- Make sure the steel fixing plate is level, using a spirit level
or a plumb line

- Secure the steel fixing plate using the 5 screw anchors
and relative screws provided in the kit

- Should the refrigerant, electrical and condensate drainage
lines exit from the rear in direction “1” or “5”, make the
hole in the wall using a ø 68 mm bit, complying with the
distances indicated in the figure to the side Fig. (9).

- The hole in the wall should be made sloping downwards in
order to aid the natural flow of the condensate water, ob­serving the indications given in Fig.(11).

- Having completed all the operations for installing the steel
fixing plate, remove the reference cardboard template.

- Position the pipes according to the direction required, ben­ding them properly in order not to cause kinks in the actual
pipes.

- To position the pipes for directions “1” and “2” Fig.(10),
they must be rotated to the required direction.

- Avoid bending the copper pipes several times in the same
point, otherwise they could be damaged.

- Remove the unions and the rubber plugs from the indoor
unit refrigerant circuit fittings only at the moment of con­necting to the outdoor unit.

- If the outlet direction is “2”, “3” or “4”, use a pair of pliers to
remove the relative plastic knock-out on the unit.

Positioning the indoor unit on the steel fixing plate

After having connected the indoor unit to the outdoor unit
connecting pipes, proceed as follows:

- Attach the indoor unit to the steel fixing plate by means of
the relative slots on the back of the air-conditioner
Fig.(12).

- Then press the indoor unit fir mly onto the fixing plate, en­suring that it is secured by the spring catch designed for
the purpose.

For further safety, after having attached the indoor unit to
the previously fixed steel plate, it is advisable to make
another two holes in the wall and secure the unit using the
spacers and the screws provided in the kit.To facilitate dril­ling operations, it is advisable to fix the unit onto the fixing
plate, lift the front part and mark the drilling points on the
wall through the relative holes.Fig.(13).

The outdoor unit should be put in a position that guarantees
the minimum space for sufficient air circulation and to allow
maintenance work and the connections of electrical and re­frigerant circuit lines.
It may be installed on a floor or flat roof or wall-mounted,
provided its weight is properly supported and there is no
transmission of vibration to the adjacent rooms.

It is advisable to avoid:

- installation in cavities or air vents;

- installation where obstacles or barriers could cause recir­culation of the expelled air;

- installation in places with an aggressive atmosphere;

- installation in confined places in which the sound level of

the outdoor unit could be increased by reverberation or re­sonance;

- installation in corners where dust, leaves or anything else
usually collects, which could reduce the efficiency of the
air-conditioner by obstructing the passage of air;

- installation in places where the air expelled by the outdoor
unit could enter the inhabited rooms through windows or
doors, thereby causing discomfort to those inside;

- installation in a place where the air expelled from the out­door unit is against a prevailing wind;

- installation in a place that is in direct sunlight.

Installation of the outdoor unit drain line (if available)

During operation in the heating mode, the condensate water
may be drained from the outdoor unit through three drain
holes.

Insert the drain male fitting into the hole where drainage of
the condensate water is required and plug the remaining
two holes using the plugs B supplied in the kit, as shown in
Fig.(14).

FLOOR INSTALLATION

Installation on a floor or flat roof does not necessitate fixing
the feet to the floor. The feet should instead be placed on
supports (~70÷80 mm) to allow application of the conden­sate drain line (for units with heat pump only).

The minimum distances shown in the figure should be
observed. Fig.(15).

SUSPENDED INSTALLATION

The minimum spaces indicated should be observed for
suspended installation, which requires a support kit that
must be ordered separately.

Carefully check the structure and the capacity load of
the supporting wall. Fig.(16).

CONDENSATE DRAINAGE

I

The indoor unit is fitted with a condensate drain pipe, to
which a drainage hose (ø inside 16 mm) should be connec­ted leading to a suitable drainage outlet.

- Fasten the condensate drain pipe to the refrigerant pipes
with adhesive tape whenever the lines cross through a
wall; this is to prevent the condensate drain pipes from
being flattened. Fig.(17) - Fig.(18).

- In the summer mode of operation, check that the conden­sate is flowing out regularly.

The drainage pipe should have a 2° slope down
towards the drain;it should never slope upwards.

Check all the joints for leaks.

Apply thermal insulating material to the joints. Fig.(19).

- The condensate drain pipe should be inserted onto the

coupling located on the bottom left part of the indoor unit.
