POSSIBLE MALFUNCTIONS AND METHODS FOR THEIR ELIMINATION
1 The AC will not turn on
2 The air is not cooled/heated
3 AC control malfunctions
4 Delayed operation
5 Unpleasant odor
6 Running water sound
7 Crackling sound
8 Moisture sprayed out of the
exhaust opening
9 Delayed air discharge in the
HEATING mode
10 Air discharge interrupts for
5-10 minutes in the heating
mode
11 The RC unit does not work
correctly
37
– the plug is not firmly inserted in the power socket
– RC batteries are depleted
– overload safety has been tripped
– insufficient power system voltage
– air intake/exhaust openings blocked
– wrong temperature setting
– air filter contaminated
The appliance can malfunction because of high interference (high
static electricity levels, power supply interruptions). In this case
disconnect the AC from power supply and connect again after 2 or
3 seconds
Operating mode changes during operation may take up to 3 minutes
The AC can absorb unpleasant smells (e.g. furniture smells, cigarette
smoke) which are then expelled with the exhaust air
– caused by refrigerant circulation in the system and is not a
malfunction
– defrosting sound during heating
The crackling is caused by the temperature expansion or contraction
of the front panel
Moisture occurs if the air in the room becomes very cold because of
cold air discharge in the cooling or drying mode
The AC is not capable of immediate hot air discharge. Please wait for
2-5 minutes
The appliance defrosts automatically, perspiration appears on the
outer surface. After defrosting the unit will automatically resume
operation
– obstacles between the signal receiver and the RC unit
– RC batteries are depleted
