Filter change indicator on ventilation units constructed before 05/2017 The ventilation unit has a filter change indicator. The level of soiling of the round filter cartridges is automatically monitored by the ventilation unit. A pending air filter change is signaled both visually (type M-WRG-K only) and audibly. For the type M-WRG ventilation units, the visual indication takes the form of an exclamation mark “!“ in the top right corner of the LCD in all program and status displays:

Filter change indicator on ventilation units constructed from 06/2017

The ventilation unit has a runtime-controlled filter monitoring function with an audible indicator. It monitors the time since the last air filter change. If the last air filter change was
more than one year ago, the filter change indicator is activated and a pending air filter change is signaled. As the time for the air filter change approaches, the intervals between the audible warnings shorten over two to three weeks. The air filters must be changed when the warning signal occurs every hour and lasts for one second. This long warning period allows the user to order replacement filters in good time. No tools are needed to change the air filters.

Choice of filter

The following air filters may be used or are available for selection for the M-WRG ventilation units:

Important notes on the filter change

• Never run the ventilation unit without air filters.
• Always use genuine Meltem filters. These are precisely matched to your M-WRG ventilation units, ensure minimal pressure losses, and ensure a long service life from your ventilation units.
• DIN 1946-6 “Ventilation for residential buildings” recommends changing air filters every six months. The air filters for outdoor air and extract air should be replaced at least once a year on hygiene grounds, ideally before the cold weather starts.
• In high levels of air pollution (e.g. from road traffic or industry, rooms with high dust levels) change the air filters every six months.
• Always replace air filters in pairs. The permeability of both air filters affects the efficiency and power consumption of the ventilation unit.
• Observe the filter change indicator (see section 4.1.1 on page 7) and replace the air filters as necessary.
• Always switch the ventilation unit off at the main switch for the filter change. Otherwise, the open-air flaps will make it impossible to remove and insert the filter cartridges.

نوٽيس

• An outdoor air filter from filter class ISO ePM1 ≥50% (F7) is needed to fulfill the hygiene requirements defined in VDI 6022 and DIN 1946-6 (category H). This is available as an option.

Cleaning the ventilation unit

خبردار

• Switch off the power to the ventilation unit before cleaning.
• When cleaning, make sure that no moisture penetrates the inside of the housing.
• Never use a high-pressure cleaner, steam cleaner, or steam jet. The ventilation unit is made of high-quality plastic and requires little care.
• Wipe the outer surfaces from time to time with a soft, damp cloth. Use mild soapy water. A commercially available plastic cleaner can be used for particularly stubborn dirt.

نوٽيس

• Never use acidic, corrosive, or abrasive cleaning agents
