System is operating under pressure.
Incorrect installation could damage the diaphragm-type dryer and cause serious
injury.
O Before start-up, check that all connections, ports, and connected maintenance
units have been correctly installed.
O Make sure that no personnel are within the hazardous zone when the
compressed air supply is switched on.
1 Assembling and connecting the diaphragm-type dryer
Observe the following guidelines before assembling and connecting the
diaphragm-type dryer.
W
Thoroughly clean the lines (e.g. by blowing them out) before installing the
diaphragm-type dryer. Make sure that the system is free of particles, e.g.
from welding work or rust residues.
W
Observe the mounting orientation! Always install the diaphragm-type
dryer in the direction of compressed-air flow in the sequence:
filter (1) – microfilter (2) – dryer element (5).
W
Install a non-return valve directly downstream of the diaphragm-type
dryer. The non-return valve prevents contamination of the diaphragm-
type dryer caused by return flows of contaminated and oily air.
W
Only use Teflon tape to seal the thread connections at the input and
output! Do not use liquid sealants!
1. Fasten the mounting bracket (4) at the filter heads at the top of the diaphragm-
type dryer.
To preserve the function of the diaphragm-type dryer, it may only be
installed vertically.
2. Firmly mount the complete dryer unit to the wall.
3. Lay the inlet and outlet lines to the dryer unit.
4. Lay the condensate outlet line for the filters.
Commissioning the diaphragm-type dryer
Observe the following guidelines before commissioning the diaphragm-type
dryer.
W
Do not place the diaphragm-type dryer under sudden pressure.
W
Do not seal off the purge air outlet! For technical reasons, the air escapes
between the support tubing and adapter during operation.
1. Make sure that the diaphragm-type dryer is correctly assembled and connected
(see "Assembling and connecting the diaphragm-type dryer").
2. Gradually place the diaphragm-type dryer under pressure.

W
Do not use compressed air for cleaning (blowing off) the diaphragm-type dryer.
Maintenance
Danger of injury if maintenance work is performed under pressure or voltage!
Performing maintenance work when the device is under pressure or electrical
voltage can lead to injuries and damage to the product or system components.
O Make sure the relevant system part is not under pressure or voltage before
carrying out any service or maintenance work.
O Protect the system against being switched on.
Changing the filter element:
The filter element does not need to be changed if the pre-filtering works correctly.
Replace the entire diaphragm-type dryer if necessary.
Individual cartridges cannot be exchanged.
CAUTION
CAUTION
8 Decommissioning, Disassembly, Exchange
Danger of injury if disassembled or exchanged under pressure or voltage!
Disassembly or exchange when under pressure or electrical voltage can lead to
injuries and damage to the product or the system components.
O Make sure that the relevant system part is not under pressure or voltage
before disassembling the product or exchanging parts.
O Protect the system against being switched on.
9 Disposal
Scrap the device and fluid in accordance with local regulations.
