POINTS THE CUSTOMER SHOULD BE AWARE OF
„
COMFORT
At startup
•
After the power is initially turned on, it will take approx. 10 minutes until startup. Usually the unit will start
in 3 minutes.
Heating operation (Not for a unit for cooling only)
•
The colder it is outside or the greater the number of indoor units, the longer the time required from the
start of operation until the emission of warm air (around 35
°
C). When the outside temperature is -5 to
2
°
C, the inside temperature is 5 to 10
°
C, and total indoor unit combination is 100% capacity, the first star-
tup of all indoor units in the morning will take approximately 20 to 30 minutes.
•
Oil return operation will be performed once every 8 hours to preserve the lubrication of oil to the com-
pressor.
Since operation is switched to cooling cycle during heating operation in order to return the oil, heating
operation will not be possible for around 5 to 10 minutes.
•
When the outside temperature is 28
°
C or higher, the unit will be set to the standby mode for protection.
„
OPERATING NOISE
At startup
•
During startup, in order to emit warm or cool air as quickly as possible, the sound of refrigerant flowing
will be heard for a short time (1 to 2 minutes) from the outdoor unit.
At shutdown
•
In order to ensure smooth startup the next time this unit is operated, the outdoor unit will continue to oper-
ate for around 1 minutes after shutdown. (The time of continued operation depends on the outside tem-
perature, capacity of connected indoor units, and connection pipe length.)
Cooling at low outside temperatures
•
During cooling operation when the outside temperature is 20
°
C or less, the fan of the outdoor unit will
operate at low speed to preserve capacity and the outdoor unit valve will be opened depending on the
pressure conditions, making it more likely that the sound of refrigerant flowing will be heard.
Defrost (Not for a unit for cooling only)
•
When the outside unit is performing defrosting operation, the fan of the indoor unit will stop temporarily,
and the slight sound of refrigerant flowing will be heard.
Excessive heating load (Not for a unit for cooling only)
•
During heating operation when the outside temperature is high (15 to 24
°
C), the fan of the outdoor unit
will be operated at low speed, making it more likely that the sound of refrigerant flowing will be heard from
the outdoor unit.
