Part 1 Important User Information
1.1 General notes • This compressed air-dryer is called CA-dryer in the
following.
• The Company does not accept responsibility if safety
regulations are not met during handling, operation,
maintenance and repair, even though these are not
strictly stated in these operating instructions.
• We recommend the notice of these operating instructions verified by the operating personnel in writing (personnel file).
• We recommend translation of these operating instruction into native language of foreign workers.
• The usability and the life cycle of the compressed airdryer as well as the avoidance of premature repairs
depends on proper operation, maintenance, care and
competent repair under consideration of these operating instructions.
• Hints to figures and locations are in brackets, e.g.
(Fig. 5/2)
• Due to our position as suppliers of components we
do not always know the final usage and total range of
products' applications. We constantly improve our
products to the latest state of science and technology
and therefore, we assume that our products are free
from defects in the sense of product liability . Ho we ver ,
it cannot be excluded that during faulty operation in
critical areas of application especially at danger to life
and limb of persons involv ed, additionally safety measures may be necessary. Therefore, we request the
user of our components / units, to ensure in his own
interest, to inform us about the application of our products in order to initiate additional safety measures, if
necessary.

1.2 Safety regulations
Attention!
The operator has to observe the national working-, operating- and safety regulations . Also e xisting internal factory regulations must be met.
!
Maintenance and repair work must only be carried out
by specially trained personnel and, if necessary, under
supervision of a person qualified for this work.
• Protective or safety devices must not be removed,
modified or readjusted.
• During operation of the CA-dryer none of the protective of safety devices must be removed, modified or
readjusted temporarily or permanently.
• Use proper tools for maintenance and repair work only .
!
• Use original spare parts only.
Attention!
All maintenance and repair works must only be executed
at stopped machine, disconnected power supply and
pulled mains plug. Ensure that the CA-dr yer cannot be
switched on by mistake.
• Prior to dismounting a part under pressure disconnect the CA-dryer from all pressure sources and depressurize the CA-dryer.
• Do not use inflammable solvents for cleaning.
• Keep the environment absolutely clean during maintenance and repair works. Keep free of dirt by covering the parts and free openings with clean cloth, paper or adhesive tape.
• Never weld at the pressure vessel or modify it in any
way.
11.02
• Ensure that no tools, loose par ts or similar are left in
the system.

Part 1 Important user Information
1.3 Handling with
refrigerant
• Wear eye protection and protective gloves
• Avoid contact of liquid refrigerants with your skin (frostbite).
• Do not inhale refr igerant vapours.
• To avoid higher concentrations, all work rooms must
be ventilated very well. The opening of windows and
doors may not be sufficient, so an exhausting system
must be used directly at the supply point or near the
floor.
• Do not smoke, because fire might decompose the
refrigerant. The resulting substances are toxic and
must not be inhaled.
• Do not have refrigerants escaped during filling or repair work. Cover with tape.
• Leave the room immediately and only enter after the
room has been sufficiently ventilated when refrigerant concentrations (e.g. pipe line leakages) appear
suddenly.
• Execute welding and soldering works on refrigerating
systems in well ventilated rooms only. Refrigerants
will be decomposed in flames as well as in electrical
arcs.
• The resulting decomposition products are toxic.
• Before welding and soldering at refrigerating systems,
the refrigerant must be removed.
• A stinking smell points to decomposition of refr igerant due to overheating:
- leave room immediately
- ventilate room ver y well.

1.4 First aid
1.5 Disposal
• Take victim immediately into the fresh air or into a
very well ventilated room.
• Splashes of refrigerant in the ey es must be blo wn out
with the mouth. Then rinse eyes with plenty of water.
Do not wipe with cloth!
• If the victim does not breathe, perform a mouth-tomouth resuscitation or use a respirator until the doctors arrival.
• Call the doctor and inform him that accident has
been caused by refrigerants, for refrigerant type
see identification plate!
• Never leave the victim unattended!
• When disposing of used devices, pay attention to oil
and refrigerant in the hermetical sealed refr igerating
circuit of the CA-dryers. Therefore, before dismounting, these operation media must be disposed by a
special company.
!
• The used mater ials are listed on the recycling label
inside the CA-dryer.
Attention!
Do not dispose waste oil into the environment. Do not
mix with household rubbish and do not burn in unauthorized plants.
• The escape of refrigerant into the atmosphere must
be prevented by appropriate measures.

Part 2 Installation
2.1 Transportation
2.2 Requirements on
the place of installation
!
Transportation has to be carried out in the normal operating position of the CA-dryer.
For a short time an inclined position of 45 ° is allowed.
At the site of installation, the CA-dryer can be installed
without anchorage or special foundation at the location
desired.
The CA-dryer is provided for an ambient temperature of
25 °C.
Attention!
To avoid corrosion at components of the CA-dr yer the
compressed and ambient air must be free of aggressive
parts.
The CA-dryers are provided for inside mounting.
Deviating conditions require the consultation of the manufacturer.
To prevent the condensate from freezing the room temperature must not drop below +2 °C.
!
2.3 Installation
(mounting)
Fig. 1: Installation of
CA-dryer
Attention!
At different ambient conditions pay attention to the layout data!
The CA-dryer must be installed that accessibility to the
front panel is ensured. Furthermore leave space f or service purpose on both sides of the CA-dryer (fig. 1).
Wall mounting is possible with all types.

Part 2 Installation
2.3.1 Version air cooled
2.4 Compressed air connection
!
The cooling air for the refrigerant condenser will be
sucked in at the front panel (fig. 5/3). This area must be
kept free and not be obstructed.
If necessary, sufficient cooling air supply must be provided by additional wall openings .
The cooling air outlet is positioned at the top of the unit
(fig. 5/8). Ensure a free air outlet and do not obstruct the
outlet of the cooling air.
If the CA-dryer is connected to an exhaust trunk, an additional fan must be installed to compensate the pressure drop. The controlling of the fan must be provided
through the CA-dryer.
The connection must be ex ecuted acc. to marking at the
CA-dryer (fig. 5/1+2).
For service purposes the installation of a bypass line is
recommended (additional equipment).
Attention!
Before mounting the CA-dryer, welding residual, rust or
other pollution must be removed from the pipelines to
be connected. If pollution cannot be excluded, proper
filter system must be installed
The compressed air pipes must be installed stress-free.
Expansion joints are recommended in case of vibrations
and pulsations.
2.5 Electric connection
The CA-dryers are completely equipped and wired. They
merely have to be connected to a power supply. The
CA-dryers are to be protected by slow-blow fuses as
defined in the wiring diagram.
Operation voltage: acc. to name plate or wiring diagram resp.
Attention!
Due to transportation reasons the power connection
cable with installed cable gland is located inside the casing of the CA-dryer.
After removal of the side wall (fig. 5/9) the cable gland
is mounted and fastened in the corresponding passage (fig. 5/6) of the casing.

Part 2 Installation
2.6 Connection condensate drain
Attention!
A hose must be fixed at the condensate drain and led
out of the casing.
An opening (Fig. 5/7) can be used for leading out the
!
!
hose.
For safety reasons the side wall must be closed again.
The CA-dryer separates water as well as oil from the
compressed air. The water/oil mixture must not be led
into the sewage. Water and oil must be separated by
suitable separators (additional equipment).
Attention!
Route outflow so that persons or objects will not be struck
by condensate (condensate outlet with operating pressure)!
