4.3 Disassembling the unit
The machine has been designed and constructed to guarantee continuous operation.
The long service life of some components such as the fan and compressor depends
on good maintenance.
The unit must only be disassembled by a refrigerant specialist.
Refrigerant liquid and lubricating oil inside the refrigeration circuit must be recov-
ered in compliance with current norms in the country where the machine is installed.

4.4 Refrigerant leaks in the refrigeration circuit
FOREWORD
The unit is delivered in perfect working order, already charged as specified in Fig. 5.
Refrigerant leaks may be identified by tripping of the compressor overload protector
(SK).
IF A LEAK IS DETECTED IN THE REFRIGERANT CIRCUIT SEEK TECHNI-
CAL ASSISTANCE.
4.5 Refrigerant charging
(see Fig. 5)
THIS OPERATION MUST ONLY BE PERFORMED BY A REFRIGERANT
SPECIALIST.
WHEN REPAIRING THE REFRIGERANT CIRCUIT, COLLECT ALL THE RE-
FRIGERANT IN A CONTAINER AND DISPOSE OF IT IN THE APPROPRIATE
MANNER.
Characteristics of refrigerant R134a
In normal temperature and pressure conditions the above refrigerant is a colourless,
class A1/A1 gas with TVL value of 1000 ppm (ASHRAE classification).
If a refrigerant leak occurs thoroughly air the room before commencing work.
5 Calibration
The dryer is supplied factory set with the values shown in Fig. 7 and therefore re-
quires no further calibration.
6 Spare parts list
(see. Fig. 8)
This list contains the principal spare parts. When ordering spare parts always quote
