The piping system must be vented once a year as air in the system can significantly reduce the capacity of the coils.
R.6.5.1 Pump and pressure expansion
The service instructions issued by the pump manufacturer must be followed. The pressure expansion system must be
checked once a year. If necessary, the pressure must be increased to the correct level.
R.6.5.2 Condensate water drain
Once a year clean the drip tray beneath the heat exchanger, as well as the drain and the water trap. Take care that
there is sufficient water in the water trap. If a droplet eliminator has been fitted to the cooling coil, this must be checked
once a year and cleaned if necessary. See the explanation above.
R.6.6 Heating coil
After an extended running period (normally a few years) dust particles can accumulate on the surface of the coil. This
can reduce the efficiency of the coil. Cleaning must be carried out with the utmost care to ensure that the coil fins are
not damaged. The piping system must be vented once a year as air in the system can significantly reduce the capacity
of the coil.
R.6.6.1 Heating battery
Check that the frost protection system is fully operational. A battery may burst due to frost if the frost protection sys-
tem is not operational.
R.6.6.2 Cooling battery
Once a year clean the drip tray beneath the cooling coil, as well as the drain and the water trap. Take care that there is
sufficient water in the water trap. If a droplet eliminator has been fitted to the cooling coil, this must be checked once a
year and cleaned if necessary.
R.6.6.3 Electric heating battery
Check that the built-in safety thermostat with an automatic reset function and the overheat thermostat with manual re-
setting are fully operational.
