W
Pre-filter FLP and microfilter FLC: for especially strict
requirements placed on the compressed air purity.
W
Active carbon filter FLA: for filtering out odors of compressed
air. The oil mist molecules held in the compressed air will be
absorbed.
W
Operating pressure: 1.5 to 16 bar

Operation
Danger of injury if assembled under pressure or voltage!
Assembling when under pressure or electrical voltage can lead
to injuries and damage to the product or system components.
O
Make sure that the relevant system part is not under voltage
or pressure before you assemble the product.
O
Protect the system against being switched on.
Sudden surge in pressure during start-up!
If no SSV filling valve is used, the system will suddenly be under
pressure during start-up. This could cause dangerous and
sudden cylinder movements.
O
When starting up a system without an SSV filling valve,
make sure that the cylinders are in their end position. For
cylinders not in the end position, make sure they do not
present any danger.
System is operating under pressure.
Incorrect installation could damage the maintenance unit/
device and cause serious injury.
O
Before start-up, check that all connections, ports, and
maintenance devices have been correctly installed.

Operating the condensate drain
1 2 3
The condensate could cause damage to the compressed air
system.
In a semi-automatic condensate drain, the condensate is
drained as soon as the reservoir is in a pressure-free state.
Over long periods of operation, the condensate can exceed
maximum capacity and get into the compressed air system.
This could damage the compressed air system.
O
Regularly check the capacity of the collecting reservoir.
O
If the condensate reaches its maximum fill level, drain it
manually.
O
Do not allow the condensate to enter the environment in an
uncontrolled manner.

CAUTION
1
Semi-automatic condensate drain
The semi-automatic condensate drain closes at a pressure
> 1.5 bar and opens at an operating pressure < 1.5 bar.
Setting the automatic mode:
O
Open drain screw by turning it all the way to the left.
You may leave the screw one turn deep in the thread or remove
it completely.
3
Draining condensate manually
The condensate (b = max. capacity) can also be drained manually.
1. Turn drain screw (a) all the way to the right (closed position).
2. Turn drain screw (a) a few rotations to the left until condensate
flows out.
2
Fully automatic condensate drain
"Normally open" configuration
In the "normally open" configuration, the condensate drain closes
at a pressure > 1.5 bar and opens at an operating pressure
< 1.5 bar. The valve opens automatically as soon as the floater
reaches the highest point and closes again when the floater
reaches the lowest point.
Setting the automatic mode:
O
Turn drain screw to the right as far as it will go. You may leave
the screw one turn deep in the thread or remove it completely.
"Normally closed" configuration
The condensate drain is closed regardless of the operating
pressure. The valve opens automatically as soon as the floater
reaches the highest point and closes again when the floater
reaches the lowest point.
3
Draining condensate manually
The condensate (b = max. capacity) can also be drained manually.
O
Turn drain screw (a) to the left.
If the screw is screwed in completely, the automatic
drainage is blocked.

Service and Repairs

Cleaning and servicing
W
Seal all openings with suitable protective caps to prevent
detergents from penetrating the system.
W
Never use solvents or strong detergents. Only clean the
product using a slightly damp cloth. Only use water and, if
necessary, a mild detergent.
W
Do not use high-pressure cleaners for cleaning.
W
Do not use compressed air for cleaning (blowing off)
maintenance units or maintenance devices.
