The hot gas defrosting with double solenoid valve is automatically
programmed with cycle frequency, making the AS a stand-alone and
reliable machine, without the need for recurring maintenance.
The condensation water evacuation pipe must be installed and linked
to the drain located in the lower part of the the condensing part.
Crankcase heater and the speed variator for the condenser fans are
available as standard, making the unit suitable to operate at low
ambient temperatures.
The AS unit is managed through a programmed electronic control unit
positioned on the electrical panel with a user interface that allows to
set the desired temperature and operating parameters.
The through wall installation is easy and fast given the compactness of
the machine and consists of one hole on the room wall to install the
machine.
