5 Assembly, commissioning and operation

Let the product acclimatize for several hours before commissioning, other-
u
wise, water may condense in the housing.
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.
1. Make sure that the relevant system component is without pressure and
voltage before you assemble the product.
2. Protect the system against being restarted.
Sudden pressure increase during commissioning!
The system is exposed to sudden pressure on commissioning if no SSU filling
unit is used! This may result in dangerous erratic cylinder motions.
Please ensure when commissioning a system without a SSU filling unit that
u
the cylinders are in their end position or that no danger can emit from
those not in end position.
System is operating under pressure!
Incorrect installation may damage the air preparation unit/maintenance
equipment and cause serious injury.
Before commissioning, check that all connections, ports and maintenance
u
equipment have been correctly installed.

5.2 Mounting the pressure sensor

5.2.1 Flange mounting (for DIL narrow NL2, NL4, NL6)

g Fig. 3
1. Remove the blanking screw (a).
2. Insert the O-ring (b) in the seal channel (c) of the air connection.
3. Place the pressure sensor (d) on the flange and screw it tight.

5.2.2 Pipe connection

g Fig. 4
1. Remove the blanking screw (e).
2. Close the double nipple (h) with the seals (g1+g2) and screw the double nip-
ple (h) into the distributor (seal channel (f)).
Notice: The double nipple (h) must be ordered separately, seals (g1+g2) are
included with the double nipple.
3. Screw the pressure sensor (i) onto the double nipple (h).

5.2.3 Special case NL6, DIL

g Fig. 6
Only flange mounting (see description g 5.2.1. Flange mounting (for DIL narrow
NL2, NL4, NL6)) or pipe connection (see description g 5.2.2. Pipe connection) is
possible at the top and only pipe connection (see description g 5.2.2. Pipe con-
nection) is possible at the bottom.
NL6, DIL does not have a connection thread, therefore connection
plates are required to connect the distributor at the sides. See
Fig.g Fig. 7.
Block assembly kits are required for mounting the distributor NL6, DIL
to the stop plate of the air preparation unit/maintenance equipment.
See Fig.g Fig. 7.

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 air preparation unit
or equipment.

7 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 without pressure or voltage be-
fore disassembling the product or exchanging parts.
2. Protect the system against being restarted.

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
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 without pressure or voltage be-
fore disassembling the product or exchanging parts.
2. Protect the system against being restarted.

9.1 Change flow direction

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:

9.1.1 Distributor conversion

On all components, the flow direction change is performed by rotating an instal-
lation by 180° around the vertical axis. The housing covers need to be changed
for the purpose.
Changing the housing cover (NL2, NL4, NL6)
g Fig. 8
Changing the housing cover is not possible on the NL1.
1. Remove the side cover caps on the compressed air connections by sliding a
suitable tool under the cover cap vanes, carefully lifting them up and taking
them off.
2. Lift the front a rear cover cap by pushing the lock-in bolts (2 on each side) up
on the latches.
Remove the cover caps carefully and evenly so that the 4 lock-in bolts
do not break off.
3. Now lift the front and rear cap evenly by carefully levering them open with a
suitable tool and taking them off.
