CO₂ ZEAS outdoor unit and capacity up unit
4P704142-1 – 2022.08
WARNING
The R744 refrigerant (CO
2
) inside the unit is odourless,
non-flammable and normally does NOT leak.
If the unit is installed indoors, ALWAYS install a CO
2
detector according to the specifications of standard
EN378.
If the refrigerant leaks in high concentrations in the room,
it may have negative effects on its occupants such as
asphyxiation and carbon dioxide poisoning. Ventilate the
room and contact the dealer where you purchased the
unit.
Do NOT use the unit until a service person confirms that
the part from which the refrigerant leaked has been
repaired.
WARNING
Do NOT modify, disassemble, remove, reinstall or repair
the unit yourself as incorrect dismantling or installation
may cause an electrical shock or fire. Contact your dealer.
CAUTION
Do NOT insert fingers, rods or other objects into the air
inlet or outlet. When the fan is rotating at high speed, it
will cause injury.
CAUTION: Pay attention to the fan!
It is dangerous to inspect the unit while the fan is running.
Make sure to turn OFF the main switch before executing
any maintenance task.
CAUTION
After a long use, check the unit stand and fitting for
damage. If damaged, the unit may fall and result in injury.
CAUTION
Before accessing terminal devices, make sure to interrupt
all power supply.
