12. 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 W air curtains are made with components of proven quality and do not require special maintenance. Howe-
ver, 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.

12.1. 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 li-
ghtening of the fi xing screws.
• Check internal inlet "plenum" together with the water coil and remove any residue or
object present. Use a vacuum cleaner to remove dust or steam to remove stuck dirt. If
you use steam, do it with the lowest possible temperature and pressure. Also, always
clean in the opposite direction to the airfl ow. Remove the air fi lter from the air curtain
to avoid damaging it.
• 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 stren-
gth as they could be damaged.
• Before winter, check the operation of anti-frost protection, the main circulation pump
(not included) and the adjustment of the control valve (not included).
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.
Access to specifi c parameters of Modbus network protocol. Avoid modifi cations except
being a specialist in this fi eld.
