Start up dryer

►
Slowly open the compressed air inlet valve, installed by the owner, upstream
of the dryer.
►
Switch on dryer: to this end, set the ON/OFF switch to
I
.
If the dryer is taken into operation for the first time, or after a change of drying
agent, the following intermediate step is meaningful. In the case of a restart
situation, the following intermediate step can be skipped.
Operating the dryer for the first time (or after a change of drying agent) separately
Depending on the transportation and storage conditions, the drying agent in the
chambers can already be loaded with humidity from the environment. At each
first start-up it makes sense therefore to operate the dryer from some time
separately from the compressed air system. This causes the drying agent in each
chamber to be regenerated repeatedly and thus to be prepared optimally for the
take-up of humidity.
Note:
Depending on the pressure dew point to be achieved, we recommend
to operate the dryer at first start-up without compressed air
consumption:
for at least 4 hours at a pressure dew point of –25 to –40 °C or
for approx. 3 to 5 days at a pressure dew point of –70 °C.
If you wish to take the dryer into operation in accordance with our
recommendation, proceed as follows:
►
Ensure that the compressed air outlet valve installed by the owner is closed.
►
Keep the compressed air outlet valve closed for the time period
recommended above.
Then the dryer can be taken into service in the compressed air system as
described in the following section:
Operate dryer immediately in the compressed air system
►
Ensure that the compressed air system downstream of the dryer is
pressurised or that a start-up device (option, see page 17) was installed into
the compressed air system directly downstream of the dryer.
The importance of this increases with the size of the compressed air system
downstream of the dryer. Smaller compressed air systems can be
pressurised also by means of compressed air fed through the dryer.
Slowly open compressed air outlet valve!
Avoid a sudden drop in pressure in any circumstance! If pressure drops
too fast, this may cause damage to the dryer. Therefore, the compressed
air outlet valve must always be opened quite slowly!
►
Slowly open the compressed air outlet valve installed by the owner. The
pressure should not drop below the operating pressure (if poss.). If
necessary, keep the compressed air outlet valve in a slightly open position
until the compressed air system downstream of the dryer has filled up
completely; only then should the valve be opened fully.
The dryer has then be taken into operation within the compressed air system.
