4.7.1 Installing the filter media

The cooling unit condenser is finished all over with a
dirt-repelling, easy-to-clean RiNano coating. In many
cases, therefore, the use of filter media is unneces-
sary, particularly in the case of dry dusts.
For dry, coarse dust and lint in the ambient air, we
recommend installing an additional PU foam filter
mat (available as an accessory) in the cooling unit.
For air containing oil condensation, we recommend
the use of metal filters (also available as an accesso-
ry). When used in textile plants with heavy lint con-
tamination, lint screens should be used (available as
an optional extra).
• Pull the louvred air inlet grille from the enclosure.
• Insert the filter mat into the louvred grille as shown
in Fig. 30 and push it back onto the enclosure.

4.7.2 Fitting the cooling unit

For partial and full internal mounting only.
• Connect the connector to the rear of the display.
• Place the louvred grille onto the unit at the front,
and press it down until you hear it snap into place.

4.7.3 Setting the filter mat monitor
(only with e-Comfort controller)
Function of the filter mat monitor:
Dirt on the filter mat is automatically detected by
measuring the temperature difference in the external
circuit of the cooling unit (see "6.2.6 Programming
overview", page 26). As the level of filter mat soiling
rises, the temperature difference will increase. The
nominal value of the temperature difference in the
external circuit adapts automatically to the relevant
operating points in the performance diagrams.
Hence there is no need to readjust the nominal value
for different operating points of the cooling unit.

Caution! Risk of damage!
The oil must collect in the compressor in
order to ensure effective lubrication and
cooling.
Do not operate the cooling unit for
at least 30 min. after assembling the
equipment.
• Once all the assembly and installation work is com-
plete, switch on the power supply to the cooling
unit.
The cooling unit starts running:
– With Basic controller: The green operating LED
("line") is illuminated.
– With e-Comfort controller: The software version
of the controller first appears for approx. 2 sec.,
followed by "ECO" for activated eco-mode. Then
the enclosure internal temperature appears in the
7-segment display.
You can now make your individual settings on the
unit, e.g. set the temperature or (with e-Comfort con-
troller only) assign the network identifier, etc. (refer to
the "Operation" chapter).
