Maintenance
For reasons of safety, the power supply and hydraulic circuit
must be disconnected prior to any maintenance activity.
If the unit was operated in heating mode, you have to wait until
the register has cooled down.
Disassembling the units
The screws attached to the device allow easy dismounting of the
grille, in order to carry out the maintenance activities.
Air ducts and plenum box
Clean them by blowing compressed air through them or using
non-aggressive cleaners.
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:
If condensates are detected, interrupt the hydraulic circuit and
find the possible cause of the problem.
Grilles
Clean them by blowing compressed air through them or using
non-aggressive cleaners.
When performing maintenance activities, it is rec-
ommended wearing personal protective equip-
ment, in order to avoid cuts and other injuries
produced by sharp and pointed parts.
To avoid accidental rotation or folding down of the
grille, please check that the locks are properly
closed.
For reasons of safety, the power supply and hy-
draulic circuit must be disconnected prior to any
maintenance activity.
- If the register is dirty, clean it
by spraying it with water or compressed air or by evacua-
tion.
- Please do not use any scouring agents for cleaning since
these materials may impair or damage the DISA-W (gal-
vanised 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.
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.
