MAINTENANCE INSTRUCTIONS
(qualified personnel only)
WARNING: the repair and/or maintenance operations must only be performed by qualified personnel,
exclusively using genuine spare parts. Before performing any maintenance operations, disconnect
the equipment from the mains.
Before performing any maintenance operations we recommend that you purchase any spare parts
from the authorised dealers or directly from the Manufacturer.
5.1
Refrigerating unit maintenance
The refrigerating circuit requires no maintenance (please refer to the tank maintenance).
Components are cleaned during the anode and tank maintenance.
5.2
Water circuit / Condensate discharge
The water circuit check is limited to the integrated filter installed by the customer (if any; in this case follow the
instructions provided by the valve manufacturer); also check the tightness of the valves, of the screw connections,
etc.; should they be loose, have them tightened by technicians.
As to the condensate drain, you have to check its operation, the condensate elimination (transparent plastic pipe),
the tightness and the presence of any impurities at the pipe ends, cleaning them if needed.
5.3
Air circuit supply
Maintenance operations only include the cleaning of the evaporator, when needed or at the end of each shift, when
checking the protective magnesium anodes.
WARNING: Danger of injuries due to the presence of sharp edge blades. The blades must not be
deformed or damaged – (comb blades of the condenser).
5.4
Descaling and limestone deposit removal
(periodic)
To get a good yield out of the equipment we recommend that you periodically descale the resistance. The frequency
of this operation depends on water hardness; proceed as follows:
•
cut off the power supply to the equipment;
•
empty the tank (please refer to the relevant section);
•
using a screwdriver, remove the cap protecting the electrical components;
•
disconnect the electric cables from the relevant terminals;
•
uninstall the counterflange using an appropriate wrench for M10 nuts;
•
extract the counterflange from its housing;
•
uninstall the resistance using an appropriate hexagonal wrench;
•
descale it and remove any limestone deposits, paying attention not to damage the resistance shell;
•
reinstall the resistance, tightening the M10 nuts to a torque of 12 Nm; tighten the nuts in a cross-shaped
pattern. Pay attention to the proper positioning of the gasket and of the screws on which the nuts are
tightened;
•
fill the tank and verify that there are no leaks;
•
restore the electrical connections and reinstall the cap protecting the electrical components.
