The only maintenance required is periodic cleaning of the memory blocs. The cleaning intervals
can be defined by visual inspection.
The memory blocs are to be taken off as follows for cleaning:
1. Switch the safety switch to OFF, it must be ensured that the accubloc - control is off.
2. Dismount the AHU wall on the access side.
3. Dismount the cover sheet for the damper linkage.
4. Dismount the damper linkage.
5. Unscrew the metal cover.
6. On site an adapted devise must be mounted on the accubloc frame, which allows the extrac-
tion of the memory blocs. The device should contain a guide and an end stop, similar to the in-
ternal guide rails.
Be careful!
The memory blocs move very easily.
7. The second memory bloc is reachable when the wall between the memory blocs is pulled out.
Therefore, there are two handle holes on the upper half.
8. The memory blocs could be cleaned with compressed air or with a high-pressure-cleaner.
Thereby, the distance of the nozzle lance must be big enough, to ensure that the structure of
the memory blocs do not get damaged. If chemical cleaning additives are used, only for alumi-
num suitable and non-alkaline cleaning agents are allowed.
9.11 Refrigeration circuit
To make sure that the environmental requirements are implemented and that the operational relia-
bility and a long lifetime of refrigeration circuit is ensured, periodic leakage checks, maintenance
and visible checks are required.
9.11.1
Leakage checks
-
Have to be performed according to EU-regulations indicated in
Records for refrigeration circuit
application in air-conditioning units
supplied by EUROCLIMA. The checks must be executed by
a certified refrigeration technician. The intervals for the checks depend on the refrigerant filling
quantity.
-
Have to be documented in
Records for refrigeration circuit application in air-conditioning units.
The type of refrigerant and the refrigerant filling quantity is attached on a sticker applied next to
compressor.
