WIFI connection

To program your air conditioning to be at the temperature you want before you even get home. You will have the ability to adjust it from a simple app. Your home to your liking.

Your air conditioner according to the size of your room

Depending on the type of house you have and the layout of the house there are several options for air selection. If you do not have a previous installation for the air conditioning ducts in your home, the most recommended solution is to install fixed air conditioners.

When deciding on one model or another, we must know the surface area of the rooms to determine the power of the device and its consumption.

The power of the equipment is determined by the square metres of the room. For example, for a room of 30m2 we will need an appliance of 3000 and 4000 frigories, or 3.48 W/h and 4.65 W/h respectively.

ROOM TO BE COVERED ( m^2 ) FRIGORIES CALORIES
Up to 40m^2	5.000 Frigorías / h 6.000 kcal/h
Up to 60m^2	7.000 Frigorías / h 8.000 kcal/h
Up to 70m^2	18.000 Frigorías / h 20.000 kcal/h
Up to 90m^2	24.000 Frigorías / h 26.000 kcal/h
Up to 140m^2	36.000 Frigorías / h 40.000 kcal/h

Which type of air conditioner is most efficient and powerful for your home?

To find out the consumption of the appliance, we will be guided by the energy efficiency label. energy efficiency label:

1. Product
2. Model
3. Energy classification
4. Annual energy consumption by geographical area
5. Cooling capacity
6. SEER:

Seasonal energy efficiency in cooling. This figure compares the energy efficiency of air conditioning systems. The more kilowatts generated per kilowatt consumed, the more efficient an air conditioner is.

When the SEER is greater than 8.5, the air is class A+++ (the most efficient). Conversely, if the SEER is between 3.1 and 3.6, the air is E-class.

1. Heating capacity

2. SCOP:

Seasonal heat energy efficiency. This data compares the energy efficiency between heating systems.

When the SCOP is higher than 5.1, the air is class A+++ (the most efficient). On the other hand, if the SCOP is

On the other hand, if the SCOP is between 2.2 and 2.5, the air is class E.

1. Noise level of the indoor and outdoor unit

How do I calculate consumption and power?

We should choose an air conditioner that is efficient because we will consume less energy, save on our electricity bill and take care of the environment.

Consumption can be calculated by dividing the power of the appliance by the SEER code or by the SCOP.

An example for an appliance with a power of 3,500W (3,000 frigories) and a SEER of 5.1:

If we switch on the equipment 4 hours a day during a summer month the cost will be €12.35*, i.e. about €0.10* per hour (*taking the cost per kW/h at €0.15).

3,500 watts/5.1 (SEER)=686 watts/hour.

(0,686kW/h x 0,15€)/1kW = 0,1029€ ; 0,1029€ x 4h x 30days = 12,348€.

To know the power, calculate approximately between 100 and 140 frigories per m2, depending on whether your house is more or less protected from cold and heat.

It also depends on the orientation, North or South, and the number of electronic devices in the room. For example, in a 20 m2 living room facing south, which is located in an area with temperatures that tend to exceed 30°C, you would have to calculate 140 frigories per square metre. The result would be 3250W or 2800 frigories.

Important safety instructions for GAS containing devices

Workplace checks.

Before starting work on installations containing flammable refrigerants, safety checks must be carried out to ensure that the risk of fire is minimised. In the case of refrigeration system repair, the following precautions should be taken before carrying out any work on the installation.

Work procedure

Work should be carried out under a controlled procedure to minimise the risk of flammable gases or vapours being present while the work is being carried out.

Work area.

All maintenance personnel and others working in the area must be informed of the nature of the work being carried out. Avoid working in enclosed spaces.

Check for the presence of refrigerant

Before and during work, the area should be checked with a suitable refrigerant detector to ensure that the technician is aware of the existence of potentially toxic or flammable atmospheres. Ensure that the leak detection equipment being used is suitable for use with all applicable refrigerants, i.e. non-sparking, properly sealed or intrinsically safe.

Presence of a fire extinguisher.

If any work is to be carried out on the refrigeration equipment or any part thereof, suitable fire extinguishing equipment must be available. Have a dry powder or CO2 fire extinguisher next to the loading area.

There are no sources of ignition.

No person performing work in connection with a refrigeration system involving exposure of any piping shall use sources of ignition in such a manner as to cause a fire or explosion. All possible sources of ignition, including cigarette smoking, shall be kept sufficiently far away from the installation, repair, removal and disposal site, during which time refrigerant may be released into the surrounding space. Before work is carried out, the area around the equipment must be inspected to ensure that there are no ignition hazards or ignition risks. No smoking" signs shall be posted.

Ventilated area.

Ensure that the area is in the open air or adequately ventilated before accessing the system or performing any hot work. A certain degree of ventilation must be maintained during the work period. Ventilation should safely disperse any refrigerant that is released and preferably expel it outside into the atmosphere.

Checking refrigeration equipment.

When electrical components are replaced, they should be fit for purpose and to the correct specification. The manufacturer's maintenance and service guidelines shall be followed at all times. If in doubt, consult the manufacturer's technical department for assistance. The following controls shall apply to installations using flammable refrigerants.

Checks of electrical devices.

Repair and maintenance of electrical components should include initial safety checks and component inspection procedures. If there is a fault that could compromise safety, no electrical supply should be connected to the circuit until it is satisfactorily resolved. If the fault cannot be corrected immediately, but continued operation is necessary, a suitable temporary solution must be used. This shall be communicated to the owner of the equipment so that all parties are informed.

Initial safety checks shall include:

• that capacitors are discharged: this must be done in a safe manner to avoid the possibility of sparking;
• that no electrical components or wiring are exposed while charging, recovering or purging the system;
• That there is continuity of grounding.

Repair of sealed components.

During repairs to sealed components, all electrical supplies should be disconnected from the equipment being worked on before removing sealed covers, etc. If it is absolutely necessary to have power supply to the equipment during repairs, permanent leak detection must be carried out. This should be done at the most critical point to warn of a potentially dangerous situation.

Particular attention must be paid to the following to ensure that, when working with electrical components, the enclosure is not altered in such a way as to affect the level of protection. For example, damage to cables, excessive number of connections, terminals not made to the original specification, damage to seals, incorrect mounting of bushings, etc.

Ensure that the product is properly assembled.

Ensure that gaskets or sealing materials have not degraded to the point where they are no longer suitable for preventing the ingress of flammable atmospheres. Spare parts must conform to the manufacturer's specifications.

Repair of intrinsically safe components.

Do not apply any permanent inductive or capacitive load to the circuit without ensuring that it will not exceed the permissible voltage and current for the equipment in use.

Intrinsically safe components are the only ones that can be worked on in the presence of a flammable atmosphere. Test apparatus must be in the correct classification.

Replace components only with parts specified by the manufacturer. Other parts may cause ignition of the refrigerant in the atmosphere due to leakage.

Wiring

Check wiring for wear, corrosion, excessive pressure, vibration, sharp edges or any other adverse environmental effects. The check should also take into account the effects of ageing or continuous vibration from sources such as compressors or fans.

Detection of flammable refrigerants.

Under no circumstances should potential ignition sources be used when searching for or detecting refrigerant leaks. A halide torch (or any other detector using an open flame) must not be used.

Extraction and evacuation

When entering the refrigerant circuit for repairs, or for any other purpose, conventional procedures should be used. However, in the case of flammable refrigerants it is important that the procedure is the most appropriate, as combustion is a factor to be taken into account. The following procedure should be followed:

remove the refrigerant

purge the circuit with inert gas

evacuate

purge with inert gas

Open the circuit by cutting or welding

The refrigerant charge shall be recovered in suitable recovery cylinders. For products containing flammable refrigerants, the system must be purged with oxygen-free nitrogen to make the product safe for flammable refrigerants. This process may need to be repeated several times. Compressed air and oxygen should not be used to purge refrigerant systems.

For products containing flammable refrigerants, refrigerant flushing should be performed by breaking the vacuum in the system with oxygen-free nitrogen and continuing to fill until working pressure is reached, then venting to atmosphere and finally lowering to vacuum. This process must be repeated until there is no refrigerant in the system. When the final charge of oxygen-free nitrogen is used, the system must be vented to atmospheric pressure in order to perform the work. This operation is absolutely vital for brazing operations performed on piping.

Make sure that the vacuum pump outlet is not close to any possible source of ignition and that ventilation is available.

Charging procedures

In addition to conventional charging procedures, the following requirements must be followed:

Ensure that you do not contaminate yourself with different refrigerants when using the charging equipment. Hoses or lines should be kept as short as possible to minimise the amount of refrigerant they contain.

Cylinders should be kept in the proper position according to the instructions.

Ensure that the refrigeration system is grounded before charging with refrigerant.

Label the equipment when charging is complete (if not already done).

Great care must be taken not to overcharge the refrigeration system.

Note: Before refilling the system, the system shall be pressure tested with the appropriate purge gas. The system shall be leak tested at the end of charging but before commissioning. A follow-up leak test shall be carried out before leaving the site.

Disassembly

Before carrying out this procedure, it is essential that the technician has a thorough knowledge of the equipment and all its details. It is recommended as good practice that all refrigerants are safely recovered. Before carrying out the task, a sample of oil and refrigerant should be taken in case an analysis is required before reusing the recovered refrigerant. It is essential that electrical power is available before starting the task.

Familiarise yourself with the equipment and its operation.

Electrically isolate the system.

Before attempting the procedure, ensure that technical equipment is available for handling refrigerant cylinders, if necessary;

Pump out the refrigerant system, if possible.

If vacuum is not possible, make a manifold so that refrigerant can be removed from various parts of the system.

Make sure that the cylinder is placed on the scale before recovery.

Start the recovery machine and operate it according to the instructions.

Do not overfill the cylinders (no more than 80% of the liquid charge volume).

Do not exceed the maximum working pressure of the cylinder, even temporarily.

When the cylinders have been correctly filled and the process has been completed, ensure that the cylinders and equipment are removed from the site promptly and that all isolation valves on the equipment are closed.

Recovered refrigerant should not be charged to another refrigeration system unless it has been cleaned and checked.

Labelling

Equipment shall be labelled indicating that it has been decomposed and drained of refrigerant. The label shall be dated and signed. In the case of equipment containing flammable refrigerants, it shall be ensured that there are labels on the equipment indicating that the equipment contains flammable refrigerant.

Recovery

When refrigerant is removed from a system, either for service or for shutdown, it is recommended as good practice that all refrigerants are disposed of safely.

When transferring refrigerant to cylinders, ensure that only suitable refrigerant recovery cylinders are used. Ensure that the correct number of cylinders are available to maintain the total system charge. All cylinders used are designated for the refrigerant recovered and labelled for that refrigerant (i.e. special refrigerant recovery cylinders). Cylinders must be complete with pressure relief valve and associated shut-off valves in good working order. Empty recovery cylinders are evacuated and, if possible, cooled prior to recovery.

Recovery equipment must be in good working order, with a set of equipment instructions at hand, and must be suitable for the recovery of all appropriate refrigerants, including, where appropriate, flammable refrigerants. In addition, a set of calibrated scales in good working order shall be available. Hoses shall be complete with disconnect couplings free of leaks and in good condition. Before using the recovery machine, check that it is in good working order, that it has been properly maintained and that all associated electrical components are sealed to prevent ignition in the event of refrigerant discharge.

Consult the manufacturer if in doubt. Recovered refrigerant shall be returned to the refrigerant supplier at the correct recovery site.

Step 3: Drill a hole in the wall for the pipe connection.

1. Determine the location of the hole in the wall based on the position of the mounting plate.
   Refer to Mounting Plate Dimensions.
2. Using a 65mm or 90mm drill (depending on models), drill a hole in the wall. Make sure the hole is drilled at a slightly downward angle, so that the outer end of the hole is lower than the inner end by approximately 5mm to 7mm. This will ensure proper water drainage.
3. Place the wall protection cap over the hole. This protects the edges of the hole and will help to seal the hole when the installation process is complete.

CAUTION

When drilling the hole in the wall, be sure to avoid cables, leads and other sensitive components.

Mounting plate dimensions

We can find different mounting plates for different air conditioner models. For different customisation requirements, the shape of the mounting plate may be slightly different. But the installation dimensions are the same for the same indoor unit size.

See Type A and Type B on the right.

Check for Electrical Leakage

During the Run Test, use an electrical probe and a multimeter to perform a complete electrical leakage test.

If electrical leakage is detected, turn off the unit immediately and call a licensed electrician to find and resolve the cause of the leakage..

WARNING! RISK OF ELECTRIC SHOCK

All wiring must comply with local and national electrical codes and must be installed by a licensed electrician.

Gas Leak Checks

There are two different methods for checking for gas leaks.

Soap and water method

Using a soft brush, apply soapy water or liquid detergent to all pipe connection points of the indoor and outdoor unit. The presence of bubbles indicates a leak.

Leak detector method

If using a leak detector, refer to the instruction manual of the device for corresponding operating instructions.

After performing the gas leak check

After confirming that all pipe connection points are NOT leaking, replace the valve cover on the outdoor unit.

A: Low pressure shut-off valve

Adjusting the angle of the air flow

Vertical adjustment

While the unit is on, use the SWING/DIRECT button on the remote controller to adjust the direction (vertical angle) of the airflow. Refer to the remote controller manual for details.

Do not move the grille by hand. This will cause the grille to become out of sync. If this happens, turn the unit off and unplug it for a few seconds, then restart the unit. This will reset the grille.

Note on moving angles:

When using COOL or DEHUMIDIFIER mode, do not place the grille at too vertical an angle for long periods of time. This may cause water to condense and drip onto the floor or furniture.

When using COOL or HEAT mode, placing the grille at too small an angle may reduce the performance of the unit due to airflow restriction. In accordance with the requirements of the relevant standards, adjust the vertical airflow grille to its maximum angle in the heating capacity test.

Horizontal adjustment

The horizontal angle of the airflow must be adjusted manually. Grasp the deflector rod (see illustration below) and adjust it manually in the preferred direction. On some units, the horizontal angle of the airflow can be adjusted by remote control.
