DANGER: RISK OF ELECTROCUTION
Do NOT leave the unit unattended when the service cover
is removed.
Mounting the outdoor unit (see
WARNING
Fixing method of the outdoor unit MUST be in accordance
with the instructions from this manual. See
DANGER: RISK OF BURNING/SCALDING
WARNING
The field piping method MUST be in accordance with the
instructions from this manual. See
8].
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.
Electrical installation (see
DANGER: RISK OF ELECTROCUTION
WARNING
Electrical wiring connection method MUST be in
accordance with the instructions from:
▪ This manual. See
▪ The wiring diagram, which is delivered with the unit,
located at the inside of the service cover. For a
translation of its legend, see
19].
WARNING
ALWAYS use multicore cable for power supply cables.
WARNING
▪ All wiring MUST be performed by an authorised
electrician and MUST comply with the 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 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
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.
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.
CAUTION
Do NOT push or place redundant cable length into the unit.
CAUTION
For use of units in applications with temperature alarm
settings it is recommended to foresee a delay of 10
minutes for signalling the alarm in case the alarm
temperature is exceeded. The unit may stop for several
minutes during normal operation for "defrosting the unit", or
when in "thermostat stop" operation.

WARNING
Charging of refrigerant MUST be in accordance with the
instructions
from
this
manual.
See
12].
WARNING
Some sections of the refrigerant circuit may be isolated
from other sections caused by components with specific
functions (e.g. valves). The refrigerant circuit therefore
features additional service ports for vacuuming, pressure
relief or pressurizing the circuit.
In case it is required to perform
brazing
on the unit, ensure
that there is no pressure remaining inside the unit. Internal
pressures need to be released with ALL the service ports
indicated on the figures below opened. The location is
depending on model type.
WARNING: MILDLY FLAMMABLE MATERIAL
The refrigerant inside this unit is mildly flammable.
