Checks
Prior to commissioning, the following items must be checked or
guaranteed:
During commissioning itself, the following items must be guar-
anteed:
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.
Air ducts and plenum box/grilles
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 condition.
To ensure this, the following maintenance activities must be car-
ried out:
If condensates are detected, interrupt the hydraulic circuit and
find the possible cause of the problem.
To facilitate the
maintenance activi-
ties, the register can
be completely re-
moved. Please follow
the sequence shown
in the following fig-
ures.
To allow the register
to be folded down, it
must be connected
to the hydraulic cir-
cuit with flexible hos-
es of sufficient
length.
- Hydraulic connections were tightened properly and exhib-
it no leaks.
- Connecting and fastening elements have been sufficiently
tightened.
- Adequate access for carrying out the maintenance activi-
ties has been provided.
- Use the on-site ventilation devices to ensure that no air re-
mains in the register and the water circuit.
- The connecting and fastening elements have been suffi-
ciently tightened.
- In heating mode, the temperature of the discharged sup-
ply air is not above 40°C.
After these items have been taken care of, the cor-
rect fastening of the device must be checked.
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.
- If the register is soiled, clean it by spraying it with water
or compressed air or by evacuation.
- 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 "combed".
- Ventilate the hydraulic circuits of the register. In doing so,
watch out for possible leaks of the hydraulic system.
