10. PRESSURE RELIEF VALVE (where provided)
10.1 Instructions and limits of use
Replacement of the pressure relief valve is suggested whenever, during the drainage, the build-up of
component processing and of the pipe residues happens to make the shutting of the seal defective.
Before you replace the valve, make sure that the system is not under pressure or at high-level
temperature in the area you are operating.
10.2 Maintenance/inspection and valve setting
Warning ! Maintenance is not provided for pressure relief valves. The removal of the cap or the
tampering with the seal are considered unauthorized modifications of the setting. This will void the
manufacturer's guarantee.
The inspection of the pressure relief valves is reserved to specific Bodies in charge and is regulated
by the current laws of the country of installation.
10.3 Expected lifetime
The pressure relief valve should be checked every 5 years.

MAINTENANCE AND CLEANING

• PLEASE NOTE: All cleaning and maintenance operations must only be performed when the
Blocksystem is switched off and disconnected from the power supply (thermomagnetic switch set
to off).
• In the event that machine parts need replacing, they have to be replaced by items exactly the
same to the originals ones
• Every week: ensure that the evaporator is clean and that there is no build-up of ice. If the
evaporator is clogged with ice, carry out a manual defrost cycle by holding down the "UP" key for
more than 5 seconds. Repeat this procedure until the evaporator is completely clean. Check after
12 hours.
• Regularly clean the condenser (at least every month) by removing all dust and grease (we
recommend using a jet of air, blowing towards the outside). If the room where the unit is located
is very dusty, more frequent cleaning may be necessary.
• Clean the fixed and mobile contacts of all contactors; replace them if they show signs of wear.
