Filter; Semi-Automatic Condensate Drain; Fully Automatic Condensate Drain; Manual Condensate Drain - Emerson AVENTICS MU1 Notice D'instruction

System is operating under pressure!
Incorrect installation may damage the maintenance unit/maintenance equip-
ment and cause serious injury.
Before commissioning, check that all connections, ports, and maintenance
u
equipment have been correctly installed.

4.1 Filter

The FLS filter is a maintenance unit component:
The passing compressed air will be roughly freed of solid contaminants and con-
densation water via centrifugal force and the filtration effect.
Steps at a glance
1. Mounting fastening elements. See g Fig. 7.
2. Connecting the filter to the tubing system. See g Fig. 9.
3. Operating the condensate drain. See g Fig. 1, g Fig. 2, g Fig. 3.

4.1.1 Semi-automatic condensate drain

Potential impairment of compressed air system by condensate!
In the case of the semi-automatic condensate drain, condensate is only dis-
charged when the reservoir is without pressure. If in operation for an extended
period, the condensate may exceed the maximum filling level and find its way
into the compressed air system. This may result in damage to the compressed
air system.
1. Regularly check the filling level in the reservoir.
2. Drain condensate manually once it reaches the maximum filling level.
3. Do not let the condensate run off into the surroundings.
See g Fig. 1.
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:
If the drain screw is screwed in completely, the automatic drainage is
blocked.
Open the drain screw by turning it all the way to the left.
u
You may leave the screw one turn deep in the thread or remove it completely.

4.1.2 Fully automatic condensate drain

See g Fig. 2.
"Normally open" configuration
In the "normally open" configuration, the condensate drain closes at a pres-
sure > 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:
If the drain screw is screwed in completely, the automatic drainage is
blocked.
Turn the drain screw to the right as far as it will go.
u
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.

4.1.3 Manual condensate drain

See g Fig. 3.
The condensate (b = max. fill level) can be drained manually.
1. Turn drain screw (a) to the left a few times until the condensate runs out.
2. Turn drain screw (a) all the way to the right (closed position).
Draining condensate via a tubing
1. Turn the drain screw (a) to the left and remove it.

2. Attach one end of the tubing to the reservoir and insert the other end into a
receptacle.

4.2 Condensate separator

See g Fig. 6.
The condensate separator discharges condensate and oil from the compressed
air network.
4.2.1 Connecting the condensate separator to the tubing system or
maintenance unit
The ideal mounting position is at the lowest point of the compressed air network.
1. Connect the condensate separator. See g Fig. 8.
2. Screw the tube into the selected G 1/2 connection.
4.2.2 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:
If the drain screw is screwed in completely, the automatic drainage is
blocked.
Turn the locking wheel (b) all the way to the left.
u
You may leave the screw one turn deep in the thread or remove it completely.

4.2.3 Connecting the tubing

A tubing (a) can be plugged onto the oil drain at the bottom for controlled oil
drainage.
1. Turn the locking wheel (b) to the left and remove it.
2. Attach one end of the tubing to the reservoir (a) and insert the other end into
a receptacle.

5 Maintenance and repairs

5.1 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.

6 Decommissioning, disassembly, exchange

Danger of injury in case of disassembly or replacement under pressure or
voltage!
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.
