Troubleshooting
Power failure
If unit display does not turn on after you press
on remote
control, and equipment does not turn on, ensure that:
—
equipment power plug, if any, is properly plugged
—
system main switch is set to “ON”
—
remote control batteries are well charged
9
If necessary, contact
R
Technical Support Service.
The climate control system does not sufficiently cool down or
warm up the air
Check that:
—
the mesh filter is clean
—
doors or windows leading outdoors are closed
—
Unit air flow is free from obstructions
—
set temperature is the one actually required

If necessary, contact
R
Technical Support Service.
faults displayed on the control panel
Faults are communicated through a code on the unit’s control
panel.

To restore operating conditions:
—
set the main switch to “Off”
—
allow 10 minutes
—
set main switch back to “ON”
—
press
on remote control
If the climate control system resumes normal operation, it means
that shutdown was due to an erratic condition.

If the fault occurs again, an accurate check of the device
components is required. Contact
R
Technical Support
Service.

faults requiring intervention of the Technical Support Service
If any of these faults occurs:
—
the power cable is too hot or damaged
—
a strange noise is heard during operation
—
either the cut-out, a fuse or grounding switch is tripping
all the time
—
a switch or a button is not operating properly
—
user smells burnt
—
water leakage from the unit
An accurate inspection of equipment components is required.
—
set the main switch to “Off”
—
immediately contact
R
Technical Support Service.
Normal noise during operation
During normal operation, the equipment may make particular
noise linked to settling, expansion of the materials or refrigerant
flow. This type of noise should not be considered a fault:
—
ticking due to expansion or shrinking of materials upon
temperature changes
—
hiss due to refrigerant cycle inversion when changing op-
erating mode and toggling between Cooling and Heating
or during defrost
—
swish similar to water flowing due to the refrigerant gas
flowing in the unit

DISPOSAL
Packing materials must be disposed of separately, in order to be
recovered and recycled. Equipment at end of life and flat bat-
teries must be disposed of as required by prevailing law and
