The only maintenance required is periodic cleaning of the memory blocs. The cleaning inter-
vals can define by visual inspection.
The memory blocs are to take 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 unit 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
extraction of the memory blocs. The devise should contain a guide and an end stop, simi-
lar to the internal management.
Be careful!
The memory blocs run very easily.
7. The second memory bloc is reachable when the wall between the memory blocs is pulled
out. Therefore are two handle holes on the upper half.
8. The memory blocs should be cleaned with water with less than 20 bar and with a dis-
tance of about 20cm from the surface of the memory bloc. If chemical cleaning additives
were used they should be suitable for aluminum (alkali-free).
9.10 Refrigeration circuit
To ensure the environmental requirements, the operational reliability and a long lifetime of
refrigeration circuit periodic leakage and maintenance checks are required.
9.10.1 Leakage checks
-
have to be performed according to EU-regulations indicated in
Records for refrigeration
circuit application in air-conditioning units
supplied by TRANE. Execution by certified re-
frigeration technician at intervals that depend on the refrigerant filling quantity.
-
have to be documented in
Records for refrigeration circuit application in air-conditioning
units.
