5.3 PERIODIC CHECKS

-  Check that the cold room temperature is close to or at the set level.

-  Check that the inlet and outlet of the air moved by the condenser are not obstructed in any way.

-  Check the amount of ice in the evaporator and if this latter is blocked, carry out a manual defrost cycle.  If the problem persists, 

modify the defrost parameters.

5.4 LONG PERIODS OUT OF SERVICE

In the event that the machine is left switched off for long periods of time, it is necessary to take the following precautions before 

switching it on again.

Before carrying out any operations, disconnect the machine from the main power supply.

-  Check that all electrical and/or water supply connections are in good condition and if necessary, call for technical assistance. 

-  Check that the spaces around the machine air inlet and outlet grids are not obstructed or reduced in any way.
