II.8.5 END-OF-DAY AND PROLONGED SHUTDOWN
The unit can be shut down at the end of the day by pressing the
ON/OFF key situated on the user interface panel. In this way power is
maintained to the compressor crankcase electric heaters and any
antifreeze devices.
IMPORTANT!
Failure to use the unit during the winter period may
cause the water contained in the system to freeze.
When the machine is out of use for long periods of time, it is necessary
to disconnect it from the mains by opening the mains switch.
All the water contained in the circuit must be drained in good time.
During installation, consider mixing the water in the circuit with the
correct proportion of ethylene glycol to guarantee protection against
freezing (see Protecting the unit from frost).

MAINTENANCE INSTRUCTIONS

DANGER!
Maintenance operations, even if for inspection
purposes only, must be carried out by skilled
technicians, qualified for working on air
conditioning and refrigerant products. Use suitable
personal protection (gloves, eye protection etc).
DANGER!
Do not introduce pointed objects through the air
inlet or outlet grilles.
DANGER!
Always use the mains switch to isolate the unit
from the mains before carrying out any
maintenance work on the unit, even if it is for
inspection purposes only. Make sure that no one
accidentally supplies power to the machine, lock
the mains switch in the OFF position.
DANGER!
In the case of cooling or fan circuit component
breakage or a drop in the refrigerant fluid charge,
the upper part of the compressor casing and the
discharge line may reach temperatures as high as
180°C for brief periods of time.
In order to guarantee that the unit runs regularly and efficiently, it is
necessary to schedule an overall inspection at regular intervals to
prevent malfunctions which could damage the main machine
components.
