The desiccant compressed air dryer should be installed in a
dry room indoors. Ample free space should be allowed for
the maintenance of the device.
The dryer is furnished in a cabinet for floor mounting.
The dryer is suitable for floor or wall mounting with a bracket
(see chapter "General Arrangement drawing“) (OPTION).
If supplied, install pre-filter and after-filter, which are packed
separately, in the pipe system. Please use the connector

4.3 Mounting
WARNING – When a valve is installed after the dryer an
appropriate safety relief valve should be installed to
prevent over pressurization of the dryer due to external
causes (fire).
CAUTION – When installing the dryer ensure all connec-
tions are even and no pressure is placed on inlet and
outlet connections.
CAUTION – Check all compressed-air connections to en-
sure that they are firm and free of leaks.
4.4 Connection to the Compressed Air System
The compressed air inlet and outlet line should be equipped
with shut off valves and a bypass system.
When installing a bypass, its function and influence on the
compressed air quality, must be known when used.
4.5 Connection to the Dryer
The dryer is shipped complete with desiccant and ready to
operate after filtration, compressed air piping, condensate
piping and electrical connections are made.
4.6 Pre- and After- Filter
IMPORTANT:
In order to ensure correct functioning of the
desiccant dryer, an oil removal filter with a max. residual oil of
0.01 ppm must be installed. To protect the down-line system
from desiccant dust, a dust filter must be installed.
4.7 Piping
The piping between the preliminary filter and the dryer must
be short and corrosion-resistant.
4.8 Electrical Connection
The dryer is equipped with a plug.
Check to see that power supply to dryer is the same as the
power requirements indicated on the identification label. Install
plug into receptacle of proper voltage or hardwire to pigtails
and ground screw inside cabinet according to electrical draw-
ings in the back of this manual. Be sure to follow all applicable
electrical codes.
4.8.1 Potential Free Contacts
All externally connected cables (pot. free wiring) should be
fixed by means of cable ties as shown in the picture.
