6 Service and repairs

6.1 Cleaning and servicing

• Close all openings with suitable safety devices so that no cleaning agent can
enter into the system.
• Never use solvents or aggressive detergents. Only clean the product using a
slightly damp cloth. Only use water and, if necessary, a mild detergent.
• Do not use high-pressure cleaners for cleaning.
• Do not use compressed air for cleaning (blowing off) the maintenance unit or
equipment.

7 Disassembly and exchange

Danger of injury in case of disassembly or replacement under pressure or volt-
age!
Disassembling or replacement when under pressure or electrical voltage may
lead to injuries and damage to the product or system components.
1. Make sure that the relevant system part is not under pressure or voltage be-
fore disassembling the product or exchanging parts.
2. Protect the system against being restarted.
Danger of burns!
The surfaces of adjacent system components can become hot during opera-
tion.
Let the system component cool off before disassembling it.

8 Disposal

Dispose of the product and condensate in accordance with the national regula-
tions in your country.

9 Conversion and extension

Danger of injury in case of disassembly or replacement under pressure or volt-
age!
Disassembling or replacement when under pressure or electrical voltage may
lead to injuries and damage to the product or system components.
1. Make sure that the relevant system part is not under pressure or voltage be-
fore disassembling the product or exchanging parts.
2. Protect the system against being restarted.
Danger of burns!
The surfaces of adjacent system components can become hot during opera-

9.1 Change flow direction

See Fig. 14
No conversion is necessary on the AS1 series. The "right/left flow" ver-
sion has a separate order number.
On delivery the flow direction is from left (1, IN) to right (2, OUT). The following
conversion on the product is necessary if the flow direction is to be changed:
Regular conversion (14-I)
On almost all components, the flow direction change is performed by rotating an
installation by 180° around the vertical axis. The housing covers need to be
changed for the purpose.
1. Remove the housing cover on the front and rear and replace at the opposite
side (the order number can now be read off at the front).
2. Mount components at position 180° around the vertical axis.
Conversion for AS2 shut-off valves and filling valves in all series (14-II)
As the exhaust is at the rear on these components, the housing cover cannot be
changed over.
Install the components rotated 180° around the lateral axis to change the flow di-
rection.

Malfunction Possible cause
Pressure/flow level is not Operating pressure too low
reached or drops off slowly.
