Clean them with an industrial vacuum cleaner or steam cleaner
or by spraying them with a non-aggressive cleaner.
Registers
To guarantee the technical characteristics of the device, the reg-
isters and heat exchangers must be kept in good clean condi-
tion. To ensure this, the following maintenance activities must
be carried out:
- Remove the secondary air grille as described above.
- If the register is dirty, clean it by spraying it with water or
compressed air or by evacuation.
- Please do not use any scouring agents for cleaning since
they may impair or damage the materials of theMainte-
nance DISA-B (galvanised steel, aluminium and copper)
and the surface coatings (paints and anodised surfaces).
- If there are larger differences in distance between the ribs,
they must be "aligned".
- Ventilate the hydraulic circuits of the register. In doing so,
watch out for possible leaks of the hydraulic system.
For reasons of safety, the power supply and hydrau-
lic circuit must be disconnected prior to any main-
tenance activity.
When decommissioning the unit or shutting it
down for a longer period in winter, the water must
be drained from the unit, in order to avoid damage
to the register due to the formation of ice. If you
want to use antifreezes, you must first determine
the freezing point.
After recharging the register, the installer has to
make sure by means of on-site ventilation devices
that no air remains in the hydraulic circuit.
