Replace drying agent
The service life of the drying agent is usually approx. 3 to 5 years. However, in favourable
installation conditions, the change of drying agent may be carried out at a substantially later
date (for notes on the installation site, see also page 10 ). The change interval is deter-
mined by the degree of contamination of the compressed air (which can be minimised by
regularly replacing upstream fi lter elements). Oil, dust, and dirt particles cover the drying
agent surface and reduce its effective surface, in part quite irreversibly. If in doubt, have a
sample of your drying agent assessed by specialists.
Comply with the following safety notes when changing the drying agent:
Wear eye protection and dust mask due to increased dust generation!
When emptying the drying agent, increased dust generation may occur.
In order to avoid any eye irritations, wear protective goggles!
In order to avoid any dust inhalation, wear dust mask!
Risk of skidding!
If drying agent has been spilt on the fl oor, there is a risk of skidding caused by
the drying agent beads. Therefore, spilt drying agent must always be taken up
immediately.
Remove used drying agent
Use an industrial vacuum cleaner to hoover up carefully the drying agent out of the cham-
bers.
Warning!
If the dryer is not used within specifi cations, the drying agent can be conta-
minated with pollutants. Always take this into account for the environmentally
safe disposal of the drying agent. The waste code numbers of the drying agent
can be obtained from the manufacturer.
Dispose of the used drying agent in accordance with all applicable regulations.
