Refill / change of coolant: Before proceeding to repair a unit with R-22 type (HCFC) coolant gas and refilling it, European Regulation 1005/2009, which currently regulates the use of coolants that affect the ozone layer, must be taken into account. Said legislation prohibits the use of virgin R-22 since 1 January 2010 and extends this prohibition, as of 1 January 2015, to the use of any type of R-22 (recycled or regenerated) for the maintenance and refill of any cooling and air conditioning unit.

In the event of having R-22 units, replacing them with other, more energy-efficient units should be envisaged. In this manner the energy and, therefore economic savings will allow fast return on investment, in addition to fulfilling environmental criteria. The energy and, therefore, economic savings will allow fast return on investment.
When the units are replaced with other new units, it may be feasible to use the existing pipes in order to minimise inconvenience and the ensuing construction work in the dwelling, with the also ensuing economic savings. This fact must be taken into account to minimise costs.
If your unit does not cool or heat as quickly and with the same power as at the start, firstly check that the internal air filters are clean, the state of the outdoor unit (with good aeration, free of surrounding obstacles and state of cleanliness). If the problem persists, it may indicate an anomaly. Nevertheless, Daikin units display error codes on their remote control that alert of any anomalies.
In coastal areas, it is advisable for the outdoor unit to be maintained and cleaned frequently by specialised personnel, due to the salt that accumulates in some of its components. This shortens the useful life and efficiency of the unit.
It is very important to clean the filters of the outdoor unit to maintain your unit in perfect working condition and avoid unpleasant odours. It is advisable to do so regularly depending on the frequency of the use time of the unit and particularly the type of room where it is installed (living room, bedroom, office, smoky rooms,...). Clean them using plenty of water and neutral soap, rinse and dry them before replacing them on the unit.
The main air filters must be replaced when they break. They are designed and manufactured to last throughout the unit’s useful life, provided that they are adequately handled and cleaned.
Another type of secondary air filters (deodorising, titanium apatite, etc.) included in some Daikin models must be maintained and replaced as recommended in its maintenance manual. In any case, they must be replaced every 2-3 years depending on the room and use of the units.
It is important to check that the power supply is stable and adequate to the characteristics of the unit. In the event that the units are electrically powered via a wall socket, do so directly and in a safe and fixed manner, avoiding the use of an extension cord and/or adaptor.
It is advisable to call Daikin’s official technical support service to perform a more in-depth revision of your unit, which will depend on its application and operating time. In any case, for domestic applications, it should be performed every three years.
If the units installed have semi-industrial or industrial application, please contact us to envisage the necessary and most suitable type of maintenance required for your unit.
Following these basic preventive maintenance recommendations for your unit will reduce potential operation problems, will improve its efficiency and allow you to save energy.
