DEFROSTING
The frost which covers the battery, obtrsucts the passage of the air, reduces the air contact surface and,
consequently, the performance; if the frost accumulation is excessive, it can seriously damage the whole
system.
All units are provided with Desfrost System.
The standard versions have their defrost simply throughy the periodic stop of the compressor, using the heat of
the environment itself.
In the versions with Hot Gas Defrost System, the defrosting is controlled by the electronic system in
combination with a thermostat, the bulb of which is installed inside the evaporator. The defrosting phase in the
Hot Gas System takes place only when the thermostat activates it in presence of freeze.
During the defrosting time the
DEFROST
light is
ON
.
4.6 MACHINE STOP (STAND BY)
If the machine is connected, it works with automatic system controlled by a humidostat. When the humidostat
activates the defrost system, only the light
Power
is
ON
When one wishes to turn off the machine, the knob of the humidostat must be set on position
OFF
.
Before the first Start-up, the machine must be kept in
STAND-BY
position at-least for 4 hours.
4.7 HUMIDITY CONTROL
It is possible to use a controller with the machine. In this case must be used a humidistat (duct or room) to be
connected to the terminal boxes of the electric panel board in place of the standard humidistat.
It is also possible to have an ON-OFF switch to be electrically connected in series to the humidistat.
