Every 4 hours, the machine goes in cooling stand - by (ventilation mode). It drains water from its tank
and re - fills it with fresh water, then goes back in cooling mode.(Elapsing time between the tank’s
water change can be modified depending on environmental conditions and/or kind of water inlet. To
make this change it’s necessary to call the after
- sales service). Every time the evaporative cooler is
switched off, it starts a pads self clearing cycle 10 minutes long. It drains water from its tank and re -
fills it with fresh water, than it starts water re - circulation through the pads (ventilation off) to remove
residual salts and other kind of dirtiness. At the end of cycle the machine drains the water from the
tank.
2.8.2 Ventilation
Press key to choose the desired ventilation mode: (manual),
(automatic),
the ma- chine starts ventilation function.
Press the key to display the current fan speed.
Press or keys to set the fan speed desired or the automatic speed function
“AUtO”
To save the changes and exit press the or keys or wait 1”sec.
Air flow during automatic speed function (FA) depends on the setted temperature value and the
temperature value detected by the probe. If the probe detects, inside the building, a temperature
value higher than the value setted, the fan start on higher speed until it reaches the setted tempera-
ture value. When the temperature is reached, the fan goes on lower speed. If the temperature rises
If during normal operations of your cooling unit, the “EA” code appears on the control panel, it is most
likely that dirtiness has accumulated (e.g. : leafs, etc.) around the discharge valve and it doesn’t allow
the complete evacuation of the water or it could be the level switch that doesn’t work properly. The
error signal can be reset by turning off the machine. If when turning back on the machine the signal
appears again after about 1 minute, a technical problem does persist so it’s better to contact the in-
staller or the after sales service.
If during normal operations of your cooling unit, water drips continuously through overflow holes, it is
most likely that the level switch is not working properly. Contact the installer or after sales service.
In both cases it would be best to shutdown the plant
,
cut - off electrical power, close the water tap
,
get
in touch with the installer who constructed the plant or a licensed technical service center.
2.2.7 Operating faults
2.2.8 Bus System
Comfort line models have on - board printed circuit that allows to have a BUS System connection
called CBS or a one command control system called CABS. The CBS system can be controlled by a
P.C. and can manage up to 58 units. The CABS System can manage groups of 5 unit controlled by
one remote command. It is possible to have these systems implemented even after the cooling sys-
tem is installed. For further information, please contact Impresind srl
