Airwell Maintenance and Servicing Dubai

  1. Normal maintenance of the appliances is generally limited to replacing filters.
  2. The filters must be changed at regular intervals. The frequency is dependent on the specific application conditions. Certain installations, for example in hotels where there large amounts of fluff due to the frequent bedding changes and the presence of fitted carpets, require more frequent filter changes. It is recommended that the filters are checked every 60 days during the first year of operation in order to determine the frequency required. If it is not possible to see light through the filter when it is held up to the sun or in front of a strong light, the filter must be replaced. A more rigorous standard of cleanliness may be required.
  3. The condensates tray must be checked annually and cleaned and rinsed if necessary.
  4. On commissioning, a record of voltages, current draw and temperature variances should be made. Thereafter, on an annual basis further measurements can be compared to these initial values and will be useful for giving an overall indication for the equipment’s general condition.
  5. The activation of the unit’s safety protection devices is usually caused by air or water problems. These forced stoppages are a normal protection measure. Ensure that there is no dirt or debris in the air or water circuits. Check the water and air temperatures and flows (clogged filters).
