5. MAINTENANCE
5.1 Routine maintenance
HEOS BOX is a product that requires minimal maintenance. Always comply
with the minimum clearances described in "DIMENSIONS AND WEIGHTS"
so as to be able to carry out routine maintenance operations safely.
The only maintenance operations required by the user are the following:
Maintenance operations to be carried out monthly:
• visually inspect the outside of the box. Make sure there are no water
spills or dripping due to condensation;
Maintenance operations to be carried out every three months:
• keep the area around the box clean and uncluttered, making sure
there is sufficient air change and enough free space in front of the two
ventilation grilles for air intake and exhaust on the electrical panel (pos.
3 and 4) and the refrigerant circuit compartment (pos. );
• remove any built-up dust or debris from the two air grilles that may
affect the flow of air inside the box;
• leakage of refrigerant and/or lubricant fluid (stains or drops on the
piping, on the piping insulation or the structure);
• water spills or dripping due to condensation;
• build-up of dust or debris inside the electrical panel and/or refrigerant
circuit compartment;
• traces of moisture dissolved in the refrigerant, by observing the colour
of the liquid/moisture indicator (pos. 16) installed in the refrigerant
circuit compartment;
• clean and, if appropriate, replace the water filter installed in the water
line outside of the unit.
Maintenance operations to be carried out every six months:
• visually inspect the inside of the box every six months. It is forbidden
to remove the outer protection panels without first disconnecting the
unit from the power supply, moving disconnect switch QS1 to OFF (see
the wiring diagram). Temporarily remove the protective panels on the
refrigerant circuit compartment and the electrical panel, and make sure
the following are absent:
