Heat pumps AIR / WATER
Operation manual 40
After installation, filters in the heating system must be cleaned twice a year. If it
is apparent that cleaning twice a year is not necessary, this interval may be
extended.
5.5.1 Filter cleaning process
When opening the filter cover, keep a cloth handy, usually with less water
flowing out.
For cleaning filter:
• disconnect the heat pump from the power supply
• turn the shut-off valves before and after the filter to the
closed position
• unscrew and remove the filter cover – keep a cloth at hand,
less water will leak out.
• remove filter
• rinse the filter
• remount the filter
• check for damage to the sealing ring on the filter cover
• screw the cover back into place, tighten with a wrench
• turn the shut-off valves before and after the filter to the open position
• turn on the heat pump
5.6 Ventilating the system
Air in the heating system reduces heat transfer and
can therefore significantly reduce heating efficiency.
Therefore, when designing the heating system,
sufficient ventilation possibilities are taken into
account. It is necessary to regularly check the
system's aeration and continuously ventilate it.
