Check the value again after approximately 15 minutes of operation, one more adjustment might be necessary.
Regeneration air flow must always be controlled. Check the regeneration air duct for allowing free blowing of
the regeneration air. Check that the regeneration air duct is installed draining from the dehumidifier.
Check the air flows using a suitable instrument (pitot pipe/thermo-anemometer or similar) in the duct.
Use a standardised tool for measuring the velocity according to specifications.
With the electrical settings and air flows are adjusted, the dehumidifier will then operate automatically by
means of the internal control - and safety functions – controlled by an external hygrostat.
Once the commissioning procedure has been completed and the air flows have been adjusted, the dehumidifier
will operate automatically thanks to the internal control, including the safety function, controlled by an external
hygrostat.
Regulations by hygrostat
The dehumidifier is prepared for external regulation by a hygrostat. To be connected the hygrostat connector,
using the corresponding male socket, part no 112002 (option). Hygrostat ex Cotes DR10.
Electric connection
The dehumidifier CR240 is connected 230V, 1PH+N+PE. The dehumidifier is supplied with build in socket for
different cable length and plug for the power supply. This cable is connected to the left socket (Power) on the
control panel. Connection of hygrostat, see “Regulations by hygrostat”, above, on this page.
Power consumption & airflows
The energy consumption of the PTC-heater is depending on the air flow passing through. At the nominal
regeneration air flow of 40 m3/h the energy consumption of the heater is 966W, which is equivalent to
indication of 4,5A on the Ammeter (whole machine consumption).
Air flow and energy consumption are regulated by a damper installed in the regeneration air duct system.
NOTICE: the energy consumption of the electric heater in the first seconds is up to 8,6A
