LREN8~12A + LRNUN5A
CO₂ ZEAS outdoor unit and capacity up unit
4P704141-1F – 2024.12
WARNING
Install safety valves in a proper way according the
applicable national regulation.
WARNING
To ensure that the safety valve(s) and the changeover
valve are properly reinstalled, a leak test is mandatory.
WARNING
Before putting the system into service, check if all field
supplied components or indoor units comply with pressure
test specifications of EN378-2. If you are not sure, it is
recommended to perform the test below.
CAUTION
When installing a safety valve, ALWAYS add enough
support to the valve. An activated safety valve is under
high pressure. If not installed securely, the safety valve
may cause damage to the piping or the unit.
CAUTION
Do NOT open the stop valve until you have measured the
insulation resistance of the main power supply circuit.
CAUTION
ALWAYS use nitrogen gas for leak tests.
CAUTION
ALWAYS use K65 T-joints for refrigerant branching.
CAUTION
Install the refrigerant piping or components in a position
where they are unlikely to be exposed to any substance
which may corrode components containing refrigerant,
unless the components are constructed of materials that
are inherently resistant to corrosion or are suitably
protected against corrosion.
Electrical installation (see "14Electrical installation"[431])
DANGER: RISK OF ELECTROCUTION
WARNING
Electrical wiring MUST be in accordance with the
instructions from:
▪ This manual. See "14Electrical installation"[431].
▪ The wiring diagram of the outdoor unit, which is
delivered with the unit, located on the inside of the top
plate. For a translation of its legend, see "19.3 Wiring
diagram: Outdoor unit"[450].
WARNING
Provide adequate measures to prevent that the unit can be
used as a shelter by small animals. Small animals that
make contact with electrical parts can cause malfunctions,
smoke or fire.
WARNING
▪ If the power supply has a missing or wrong N-phase,
equipment might break down.
▪ Establish proper earthing. Do NOT earth the unit to a
utility pipe, surge absorber, or telephone earth.
Incomplete earthing may cause electrical shocks.
▪ Install the required fuses or circuit breakers.
▪ Secure the electrical wiring with cable ties so that the
cables do NOT come in contact with sharp edges or
piping, particularly on the high-pressure side.
▪ Do NOT use taped wires, extension cords, or
connections from a star system. They can cause
overheating, electrical shocks or fire.
▪ Do NOT install a phase advancing capacitor, because
this unit is equipped with an inverter. A phase
advancing capacitor will reduce performance and may
cause accidents.
WARNING
▪ All wiring MUST be performed by an authorised
electrician and MUST comply with the applicable
national wiring regulation.
▪ Make electrical connections to the fixed wiring.
▪ All components procured on-site and all electrical
construction MUST comply with the applicable
legislation.
WARNING
If NOT factory installed, a main switch or other means for
disconnection, having a contact separation in all poles
providing full disconnection under overvoltage category III
condition, MUST be installed in the fixed wiring.
WARNING
ALWAYS use multicore cable for power supply cables.
WARNING
Use an all-pole disconnection type breaker with at least
3 mm between the contact point gaps that provides full
disconnection under overvoltage category III.
WARNING
If the supply cord is damaged, it MUST be replaced by the
manufacturer, its service agent or similarly qualified
persons in order to avoid a hazard.
CAUTION
This equipment is NOT intended for use in residential
locations and will NOT guarantee to provide adequate
protection to radio reception in such locations.
Charging refrigerant (see "15Charging refrigerant"[439])
WARNING
Charging of refrigerant MUST be in accordance with the
instructions from this manual. See "15 Charging
refrigerant"[439].
