Installation Of The Probes - AKO -16524A Guide Rapide

Installation of the probes

To achieve maximum performance from the advanced controller, the correct installation of the probes is key, as
they are responsible for calculating the evaporator's thermal transfer coefficient, evaluating the start and end of the
defrosts and diagnosing problems in the evaporator.
Material included
-4 mm hermetic evaporator probe, 1.5 m of cable.
-Ambient probe
-1 mounting clip for 10-13 mm coil
-1 mounting clip for 14-18 mm coil
-1 mounting clip for 19-21 mm coil
-1 mounting clip for 22-25 mm coil
Location of the ambient probe
The probe should be located in a place that does not directly receive the flow of cold air from the evaporator.
Preferably in its air aspiration area.
Location of the evaporator probe
The probe must be located as near as possible to the inlet of refrigerant from the evaporator (close to the
expansion valve) in the finned area.
In certain evaporators, for example cubic ones, this inlet may be located on the front part of the battery, just behind
the fan.
If defrost is done by electric heat, the probe must be located far away from them and, if possible, in the area of the
evaporator where defrosting is slower, in other words, in the last area to defrost.
If the two conditions are not possible, the best possible compromise must be looked for.
Select the appropriate clip
depending on the size of its
evaporator pipe.
Attach the probe to the pipe
using the clip, making sure that
its end is in direct contact with
the tube.

Bend the fins of both ends of the
probe to increase the fixing and
contact surface.
