6. Operation tips and safety
Operation tips
• Do not over-cool the room
temperature. This is not good for
health and wastes electricity.
• Keep curtains closed. Do not let
sunshine enter the room directly when
the air conditioner is in operation.
• Keep the room temperature uniform.
Adjust the vertical and horizontal
airflow direction to ensure a uniform
temperature in the room. Air can’t be
discharged to the direction of air in.
• Make sure that the doors and windows
are tightly closed. Avoid opening doors
and windows as much as possible to
keep air conditioning in the room.
• Clean the air filter regularly. Blockages
in the air filter reduce dehumidifying
effects. Clean the air filter at least once
every two weeks.
• Ventilate the room occasionally. Since
windows are kept closed, it is a good
idea to open them and ventilate the
room now and then. When starting the
unit, curtains or windows should be
closed to prevent the heat/cool leakage.
CAUTION
Operations for safety and health
1. The plug must be accessible after the appliance
is positioned.
2. Do not use this appliance in the laundry.
3. If the power cord is damaged, it must be replaced
by the manufacturers or its service agent in void
of hazard.
Safety tips
• Do not pull out the power cord.
• Damage to the cord may result in
serious electric shocks
• Do not use the air conditioner for other
purposes except for cooling the room.
• Do not use the air conditioner for
other purposes such as drying
clothes, preserving foods, or
cultivating vegetables.
• Do not block the air intake and
outlet vents. This causes lowered
performance and irregular operation.
• Do not insert sticks or other objects into
these vents as it is dangerous to touch
the electric components and the fan.
• Select the most appropriate
temperature. Pay attention to adjust
the temperature to suit the conditions.
Rooms occupied by infants,the elderly,
or the sick should be kept at an
appropriate temperature.
• Do not use heating apparatuses in
the vicinity. The air conditioner’s
plastic parts will melt if exposed to
excessive heat.
• Avoid exposing the body directly to a
continuous unidirectional air flow for
long periods This is not recommended
for health reasons.
Note
Always wait at least three minutes before switching the air
conditioner on again after you have switched it off during
cooling or heating.
Please note that the unit is filled with flammable gas
R32. Inappropriate treatment of the unit involves
the risk of severe damages of people and material.
The appliance must be installed, operated and stored in a
room with a floor area larger than 4m2.

9. Troubleshooting guide
Issue Possible causes
Air conditioner does not operate at all.
Is there a power failure?
Is the plug out?
Is power fuse or switch off ?
Is the voltage too high or too low?
Cooling or heat efficiency is not good.
Is air inlet or outlet locking?
Is there any other heat /cool source in the room?
Are the air filters very dirty?
Is indoor fan speed set at LOW?
Maybe the room is too hot/cold when the unit is started.
Foggy air flows out.
In COOL mode operation, sometimes there is foggy air flowing
out of the unit. This is because the humid air from the room has
been cooling rapidly.
The unit is normal while the indoor outlet is sending out some
odour, because the inlet air may be mixed with the smell of
furniture and smoke.
The air conditioner operation is noisy.
For a noise that sounds like water flowing: This is the sound
of refrigerant flowing inside the air conditioner unit.
For a noise that sounds like a shower: this is the sound of
the dehumidifying water being processed inside the air
conditioner unit.
Condensation appears to be leaking from the air conditioner. Condensation occurs when the airflow from the air conditioner
cools the warm room air.
Air conditioner does not operate for about three minutes
when restarted.
This is to protect the mechanism. Wait about three minutes and
operation will begin.
CAUTION
In the following situations immediately stop all operations
and pull the plug out, please contact your supplier.
• Operation starts or stops abnormally.
• Power fuse or switch often breaks.
• Accidentally splashed water or something into air
conditioner.
• Electrical lines are very hot or lines cover breaks.
• Other strange situations.
Others
• The connection between AC and power cord or among
other elements independently shall be subject to wiring
diagram on the unit.
• Model and rated value of fuse shall be subject to screen
print on corresponding controller or protective bushing.
After service
• If your air conditioner has the questions of quality or
anything else, please contact your supplier.

11.Installation notes
• Initial safety checks shall include:
- that capacitors are discharged: this shall be done in a
safe manner to avoid possibility of sparking;
- that no live electrical components and wiring are exposed
while charging, recovering or purging the system;
- that there is continuity of earth bonding.
• Checks to the area
Prior to beginning work on systems containing flammable
refrigerants, safety checks are necessary to ensure that the
risk of ignition is minimised. For repair to the refrigerating
system, DD.4.3 to DD.4.7 within ASNZS 60335.2.40-2019
shall be completed prior to conducting work on the system.
• Work procedure
Work shall be undertaken under a controlled procedure so
as to minimise the risk of a flammable gas or vapour being
present while the work is being performed.
• General work area
All maintenance staff and others working in the local area
shall be instructed on the nature of work being carried out.
Work in confined spaces shall be avoided.
• Checking for presence of refrigerant
The area shall be checked with an appropriate refrigerant
detector prior to and during work, to ensure the technician
is aware of potentially toxic or flammable atmospheres.
Ensure that the leak detection equipment being used is
suitable for use with all applicable refrigerants, i.e. non-
sparking, adequately sealed or intrinsically safe.
• Presence of fire extinguisher
If any hot work is to be conducted on the refrigeration
equipment or any associated parts, appropriate fire
extinguishing equipment shall be available to hand. Have
a dry powder or CO2 fire extinguisher adjacent to the
charging area.
• Ventilated area
Ensure that the area is in the open or that it is adequately
ventilated before breaking into the system or conducting
any hot work. A degree of ventilation shall continue during
the period that the work is carried out. The ventilation
should safely disperse any released refrigerant and
preferably expel it externally into the atmosphere.
• Checks to the refrigeration equipment
Where electrical components are being changed, they
shall be fit for the purpose and to the correct specification.
At all times the manufacturer’s maintenance and service
guidelines shall be followed. If in doubt, consult the
manufacturer’s technical department for assistance.
The following checks shall be applied to installations using
flammable refrigerants:
- the charge size is in accordance with the room size within
which the refrigerant containing parts are installed;
- the ventilation machinery and outlets are operating
adequately and are not obstructed;
- if an indirect refrigerating circuit is being used, the
secondary circuit shall be checked for the presence of
refrigerant;
- marking to the equipment continues to be visible and
legible. Markings and signs that are illegible shall be
corrected;
- refrigeration pipe or components are installed in a position
where they are unlikely to be exposed to any substance
which may corrode refrigerant containing components,
unless the components are constructed of materials
which are inherently resistant to being corroded or are
suitably protected against being so corroded.
• Checks to electrical devices
Repair and maintenance to electrical components shall
include initial safety checks and component inspection
procedures. If a fault exists that could compromise
safety, then no electrical supply shall be connected to the
circuit until it is rectified. If the fault cannot be corrected
immediately but it is necessary to continue operation, an
adequate temporary solution shall be used. This shall be
reported to the owner of the equipment so all parties are
advised:
- that capacitors are discharged: this shall be done in a
safe manner to avoid possibility of sparking;
- that no live electrical components and wiring are exposed
while charging, recovering or purging the system.
• No ignition sources
No person carrying out work in relation to a refrigerating
system which involves exposing any pipe work shall use
any sources of ignition in such a manner that it may lead
to the risk of fire or explosion. All possible ignition sources,
including cigarette smoking, should be kept sufficiently far
away from the site of installation, repairing, removing and
disposal, during which refrigerant can possibly be released
to the surrounding space. Prior to work taking place, the
area around the equipment is to be surveyed to make sure
that there are no flammable hazards or ignition risks. ‘’No
Smoking’’ signs shall be displayed.
• Repairs to sealed components
During repairs to sealed components, all electrical supplies
shall be disconnected from the equipment being worked
upon prior to any removal of sealed covers, etc. If it
is absolutely necessary to have an electrical supply to
equipment during servicing, then a permanently operating
form of leak detection shall be located at the most critical
point to warn of a potentially hazardous situation.
Particular attention shall be paid to the following to ensure
that by working on electrical components, the casing is not
altered in such a way that the level of protection is affected.
This shall include damage to cables, excessive number of
connections, terminals not made to original specification,
damage to seals, incorrect fitting of glands, etc.
- Ensure that the apparatus is mounted securely.
- Ensure that seals or sealing materials have not degraded
to the point that they no longer serve the purpose of
preventing the ingress of flammable atmospheres.

20 | Kaden Owner’s Manual
Replacement parts shall be in accordance with the
manufacturer’s specifications.
NOTE: The use of silicon sealant can inhibit the
effectiveness of some types of leak detection equipment.
Intrinsically safe components do not have to be isolated
prior to working on them.
• Repair to intrinsically safe components
Do not apply any permanent inductive or capacitance
loads to the circuit without ensuring that this will not exceed
the permissible voltage and current permitted for the
equipment in use.
Intrinsically safe components are the only types that
can be worked on while live in the presence of a
flammable atmosphere. The test apparatus shall be at
the correct rating.
Replace components only with parts specified by the
manufacturer. Other parts may result in the ignition of
refrigerant in the atmosphere from a leak.
• Cabling
Check that cabling will not be subject to wear, corrosion,
excessive pressure, vibration, sharp edges or any other
adverse environmental effects. The check shall also take
into account the effects of aging or continual vibration from
sources such as compressors or fans.
• Leak detection methods
Leak detection fluids are suitable for use with most
refrigerants but the use of detergents containing chlorine
shall be avoided as the chlorine may react with the
refrigerant and corrode the copper pipe-work.
• Detection of flammable refrigerants
Under no circumstances shall potential sources of ignition
be used in the searching for or detection of refrigerant
leaks. A halide torch (or any other detector using a naked
flame) shall not be used.
The following leak detection methods are deemed
acceptable for all refrigerant systems.
Electronic leak detectors may be used to detect refrigerant
leaks but, in the case of flammable refrigerants, the
sensitivity may not be adequate, or may need re-calibration.
(Detection equipment shall be calibrated in a refrigerant-free
area.) Ensure that the detector is not a potential source
of ignition and is suitable for the refrigerant used. Leak
detection equipment shall be set at a percentage of the LFL
of the refrigerant and shall be calibrated to the refrigerant
employed, and the appropriate percentage of gas (25%
maximum) is confirmed.
Leak detection fluids are also suitable for use with most
refrigerants but the use of detergents containing chlorine
shall be avoided as the chlorine may react with the
refrigerant and corrode the copper pipe-work.
NOTE: Examples of leak detection fluids are
- bubble method,
- fluorescent method agents.
If a leak is suspected, all naked flames shall be removed/
extinguished. If a leakage of refrigerant is found which
requires brazing, all of the refrigerant shall be recovered
from the system, or isolated (by means of shut off valves)
in a part of the system remote from the leak. Removal of
refrigerant shall be according to clause DD.9.
• Removal and evacuation
When breaking into the refrigerant circuit to make repairs
– or for any other purpose – conventional procedures shall
be used. However, for flammable refrigerants it is important
that best practice is followed since flammability is a
consideration. The following procedure shall be adhered to:
- remove refrigerant;
- purge the circuit with inert gas (optional for A2L);
- evacuate (optional for A2L);
- purge with inert gas (optional for A2L);
- open the circuit by cutting or brazing.
The refrigerant charge shall be recovered into the correct
recovery cylinders. For appliances containing flammable
refrigerants other than A2L refrigerants, the system shall be
purged with oxygen-free nitrogen to render the appliance
safe for flammable refrigerants. Compressed air or oxygen
shall not be used for purging refrigerant systems.
For appliances containing flammable refrigerants, other
than A2L refrigerants, refrigerants purging shall be achieved
by breaking the vacuum in the system with oxygen-free
nitrogen and continuing to fill until the working pressure is
achieved, then venting to atmosphere, and finally pulling
down to a vacuum. This process shall be repeated until no
refrigerant is within the system. When the final oxygen-free
nitrogen charge is used, the system shall be vented down
to atmospheric pressure to enable work to take place. This
operation is absolutely vital if brazing operations on the
pipe-work are to take place.
Ensure that the outlet for the vacuum pump is not close
to any potential ignition sources and that ventilation is
available.
• Charging procedures
In addition to conventional charging procedures, the
following requirements shall be followed.
- Ensure that contamination of different refrigerants does
not occur when using charging equipment. Hoses or lines
shall be as short as possible to minimise the amount of
refrigerant contained in them.
- Cylinders shall be kept in an appropriate position
according to the instructions.
- Ensure that the refrigerating system is earthed prior
to charging the system with refrigerant.
- Label the system when charging is complete
(if not already).
- Extreme care shall be taken not to overfill the
refrigerating system.
Prior to recharging the system, it shall be pressure-
tested with the appropriate purging gas. The system shall
be leak-tested on completion of charging but prior to
commissioning. A follow up leak test shall be carried out
prior to leaving the site.
