Air-cooled refrigeration condensing unit
4P500362-1A – 2018.09
Malfunction Measure
The system operates
but cooling is
insufficient.
▪ Check if air inlet or outlet of outdoor or
indoor unit is not blocked by obstacles.
Remove any obstacles and make sure
the air can flow freely.
▪ Check if the indoor unit is not frosted up.
Defrost the unit manually, or shorten the
defrost operation cycle.
▪ Check if there are not too many articles
inside the room/showcase. Remove a
couple of articles.
▪ Check if there is smooth air circulation
inside the room/showcase. Reorganise
the articles inside the room/showcase.
▪ Check if there is not too much dust on
the outdoor unit heat exchanger.
Remove the dust with a brush or vacuum
cleaner, without using water. If
necessary, consult your dealer.
▪ Check if there is cold air leaking outside
of the room/showcase. Stop the air from
leaking outside.
▪ Check if you did not set the indoor unit
setpoint temperature too high. Set the
setpoint appropriately.
▪ Check if there are no high-temperature
articles stored in the room/showcase.
Always store articles after they have
cooled down.
▪ Check if the door is not opened too long.
Reduce the opening time of the door.
If after checking all above items, it is impossible to fix the problem
yourself, contact your installer and state the symptoms, the complete
model name of the unit (with manufacturing number if possible) and
the installation date (possibly listed on the warranty card).
19.1 Symptoms that are NOT system
malfunctions
The following symptoms are NOT system malfunctions:
19.1.1 Symptom: The system does not operate
▪ The system does not start immediately after it is turned ON again.
If the operation lamp lights, the system is in normal condition. To
prevent overloading of the compressor motor, the system starts 5
minutes after it is turned ON again in case it was turned OFF just
before.
▪ The system does not start immediately after the power supply is
turned on. Wait one minute until the micro computer is prepared
for operation.
19.1.2 Symptom: The unit does not stop
immediately when operation is stopped
This is to prevent components from being damaged. The unit will
stop in a little while.
19.1.3 Symptom: Noise (Outdoor unit)
▪ A continuous low hissing sound is heard when the system is in
cooling operation. This is the sound of refrigerant gas flowing
through both indoor and outdoor units.
▪ A hissing sound which is heard at the start or immediately after
stopping operation. This is the noise of refrigerant caused by flow
stop or flow change.
▪ When the tone of operating noise changes. This noise is caused
by the change of frequency.
19.1.4 Symptom: Dust comes out of the unit
When the unit is used for the first time in a long time. This is
because dust has gotten into the unit.
19.1.5 Symptom: The outdoor unit fan does not
spin
During operation. The speed of the fan is controlled in order to
optimise product operation.
20 Relocation
Contact your dealer for removing and reinstalling the total unit.
Moving units requires technical expertise.
21 Disposal
This unit uses hydrofluorocarbon. Contact your dealer when
discarding this unit.
NOTICE
Do NOT try to dismantle the system yourself: dismantling
of the system, treatment of the refrigerant, oil and other
parts MUST comply with applicable legislation. Units
MUST be treated at a specialised treatment facility for
reuse, recycling and recovery.
