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).
Page 6
CONNECTION OF THE UNIT
English

Fig. 2
Fig. 3 Fig. 4
TO CONNECT
- With the coupling handle in the full backposition (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) popsinto 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 backposition (see figures 3-4).
Page 7
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 backposition (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.
DOS 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. Dont 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
.
- Dont tamper with the valves while disconnected or allow children access to disconnected couplings.
- Dont 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.

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.
