the name plate. Always use appropriate ports provided on the unit
for cable passage way. Refer also to electrical diagram supplied
with the unit.
Unit ground connection should be made using the appropriate
terminals provided outside the unit, with cables of adequate
section and carefully following all procedures and standards.
Grounding of the unit is a fundamental requirement to comply
with safety codes against electrical/electrostatic accidents.
All cables and connections of electric parts should comply with the
current IEC standards, or the standard national requirements of
the country.
• It is mandatory to install an external main switch ON site easy
to reach, to facilitate a quick and easy shutdown enabling the
power of the unit to be cut OFF.
Refer to the unit electrical schematics for the installation. Follow all
local codes.
If the unit is installed above some support, some electrical
components will result higher: use a ladder to compensate the
increased height.

The evaporative system doesn’t work when the external ambient
temperature is low (near water freezing point).
Ensure there is no risk of freezing on water traps and
on evaporative system water feeding and discharge line.
The unit must be periodically cleaned/disinfected using
liquid that must be recovered. We suggest to prepare
the discharge line ready to receive the liquid used for the
cleaning/disinfection.
