11. BASIC SERVICE INFORMATION AND MAINTENANCE
All units have been carefully checked in Factory prior to shipment. That is why the most frequent error usually
occur due to an incorrect understanding of equipment operation, wrong connections or incomplete wiring.
Therefore, it is important to carefully follow all instructions to avoid diffi cult resolution problems. Such dama-
ge will not be covered by the warranty.
COR-PRO V air curtains are made with components of proven quality and do not require special maintenance. However,
to extend life expectancy of the equipment, we recommend that maintenance inspections be carried out at least at the
specifi ed intervals and always depending on their use.
Disconnect the equipment from power supply before carrying out any type of operation on it. There is a risk of
electric shock.
11.1. QUARTERLY MAINTENANCE
• Check the integrity of suspension or anchoring elements together with tightening of connection elements.
• Complete cleaning of the inlet grille together with the discharge diffuser. Check the lightening of the fi xing screws.
• Check internal inlet "plenum" together with electric heaters and remove any residue or object present.
• Check if motor scroll and impeller are clean. Do not wash the motor with water and in any case wipe it with water and
if necessary wipe it with a damp cloth to avoid damaging the motor winding. Do not start up the air curtain during next
60 minutes after cleaning to allow moisture to disappear. In case of cleaning blades, do not apply excessive strength
as they could be damaged.
• Check the safety of the unit regarding risks of electric shock in accordance with local applicable regulations together
with grounding verifi cation.
12. PUTTING OUT OF SERVICE AND RECYCLING
EEC legislation and our consideration of future generations mean that we should always recycle materials
where possible; please do not forget to deposit all packaging in the appropriate recycling bins. If your device
is also labeled with this symbol, please take it to the nearest Waste Management Plant at the end of its servi-
ceable life.
Control with digital signals is carried out by combining three voltage-free contacts to
control fans and three more to control electric heater. Pay attention to always combine
at least one ventilation level when activating any heating level. See wiring diagram.
Special Modbus communication for specifi c coun-
tries.
Modbus Read level allows manual control by touch
screen and, at the same time, visualization through
Modbus network. See Modbus Map.
