8. ACCESSORIES
Accessories that are not included in the
standard order must be ordered separately.
Central air pump intake kit
This kit provides a properly sized central
intake filter located on the compressor
module used to supply the intakes of the
individual air pumps. This extends the central
filter replacement interval (to every 2000
hours) compared to the interval for changing
the filters on individual compressors, and
ensures simpler and faster central filter
replacement.

9. PRODUCT FUNCTION
9.1. Compressor with adsorption
dryer
Fig. 1: Compressor air pumps (12) draw in
atmospheric air through the intake filters and
compress it through non-return valves into
the compressed air system. A connecting
hose (13) connects this system to the
external adsorption dryer (8). From the inlet
to the dryer module, the air is first cooled in
the integrated cooler (9) and then through the
condensate separator (10), entering the
active chamber with adsorbent (11), 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 (21). The active chamber
switches on a cyclical basis. Dry and filtered
air then passes through the non-return valve
(23) into the air tank (2). The treated
compressed air is ready for additional use in
the air tank.

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 air
pumps is converted to heat, and
therefore the rooms in which the
compressor is installed must have
additional ventilation to provide
sufficient air exchange for cooling
purposes (see the Technical Data
chapter).
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
Placing air flow impediments
upstream or downstream of the
cooler is prohibited. The
temperature of internal and
external parts of the equipment
may rise to hazardous levels.
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.
