9. PRODUCT FUNCTION
9.1. Compressor with adsorption dryer
The compressor aggregates (1) draw air through the inlet filters (8) and compress it through check
valves (3) into a common manifold, from which it is routed to the external adsorption dryer (9)
through a connecting hose. From the inlet to the dryer module, the air is first cooled in the integrated
cooler (14) and then moves through the condensate separator (40), entering the active chamber
with adsorbent (16), where the air is dried. A portion of the air is fed into the second, regeneration
chamber, where this air is used to remove moisture from the adsorbent, after which it is released
through the silencer (38). The active chamber switches on a cyclical basis. The dry and filtered air
then passes through a check valve (31) and into the air tank (2), where it is ready for further use.
Check the dryer and the air tank check valve (31) to ensure they are operating properly if the
pressure relief valve (37) continues to open.
Adjusting the opening pressure of the pressure relief valve or other modification
of this valve is prohibited!

INSTALLATION
Risk of incorrect installation.
Only a qualified technician may install the compressor and place it into operation
for the first time. Their duty is to train operating personnel on the use and
maintenance of the equipment. An entry is made in the equipment installation
record to certify installation and operator training. (see the Annex chapter)
10. INSTALLATION CONDITIONS
The compressor may only be installed and operating in dry, well-ventilated and clean
environments under the conditions specified in the Technical Data chapter.
Risk of damage to the device.
The equipment may not be operated outdoors or in otherwise wet or damp
environments.
Risk of explosion.
Do not use the equipment in the presence of explosive gases, dust or
combustible liquids.
The compressor must be installed so that it is accessible at all times for operating and
maintenance. Please ensure that the nameplate on the device is readily accessible.
The compressor must stand on a flat, sufficiently stable base (be aware of the weight of the
compressor, see the Technical Data chapter)
The compressor on the operator’s side must be at least 70 cm from the wall to allow air flow for
cooling purposes and to ensure the safety of the operator and maintenance personnel.
Approximately 70% of the electrical energy used by the compressor aggregates is converted to
heat and therefore the rooms in which a compressor assembly is installed must have additional
ventilation to provide sufficient air exchange for cooling purposes (see the technical data).
Environmental requirement:
Temperature
+5 to +40°C
Relative humidity
70%
Max. absolute humidity
15g/m3
Burn or fire hazard! Caution. Hot surface.
Portions of the compressor, dryer and connecting hoses between the dryer and
compressor may be hot and reach hazardous temperatures during compressor
operation that may harm materials or operating staff.
High temperature hazard.
The placement of air flow impediments upstream or downstream of the cooler is
prohibited. The temperature of internal and external parts of the cooler may be
hot and reach hazardous temperatures.
You may notice a “new product” odour when you first place the product into
service (for a short period of time). This odour is temporary and does not impede
the normal use of the product. Ensure the space is properly ventilated after
installation.
