Stopping
After installion, the CA-dryer can be switched on with the
main switch (fig. 5/1).
So the refrigerating compressor heating and the SAB-
Processor is supplied with power.
Before operating the operation switch (fig. 5/2), a waiting
period of at least 6 hours is necessary, to enable a pre-
heating of the refrigeration compressor.
The CA-dryer is switched on via the operation switch (fig.
5/2). After approx. 5 minutes the compressed air admis-
sion is possible by connecting the compressed air com-
pressor.
Attention!
A period of 5 minutes must be kept between switching
off and switching on the CA-dryer to achieve a pressure
compensation within the refrigeraion system.
After some hours of operation under load, it should be
controlled that condensate is generated and drained.
The CA-dryer is designed for continuous operation and
may remain switched on during periods of no load, as it
adapts to the required performance automatically.
Operation is indicated by the luminous operation switch
(fig. 5/2).
The temperature display at the switch cabinet (fig. 5/5)
indicates the pressure dew point reached by the CA-
dryer.
During normal operation, the lamp „Power“ (fig. 9/1) lights
permanently .
At standstill periods, the CA-dryer is switched off with
the operation switch, the main switch remains switched
on.
For longer standstill periods or during service resp. the
CA-dryer is switched off with the main switch (see 4.1).
At restarting proceed as mentioned in item 4.2.
