industry-accredited assessment authority regard of flammable
refrigerants, which authorizes their competence to handle re-
frigerants safely in accordance with an industry recognized as-
sessment specification.
• Servicing shall only be performed as recommended by the
equipment manufacturer. Maintenance and repair requiring the
assistance of other skilled personnel shall be carried out under
the supervision of the person competent in the use of flamma-
ble refrigerants.
• Keep any required ventilation openings clear of obstruction.
• Refrigerant tubing shall be protected or enclosed to avoid
damage.
• Flexible refrigerant connectors (such as connecting lines be-
tween the indoor and outdoor unit) that may be displaced dur-
ing normal operations shall be protected against mechanical
damage.
• Mechanical connections shall be accessible for maintenance
purposes.
• A brazed, welded, or mechanical connection shall be made be-
fore opening the valves to permit refrigerant to flow between
the refrigerating system parts.
• Use non-flammable gas (nitrogen) to check for leak and to
purge air.
• Use only refrigerant grade pipe specific for R32 refrigerant. Do
Not Use R22 products, which have lower pressure ratings and
can result in excessive pressure, explosion and injury.
• Inert gas (oxygen free nitrogen) should be used when you
checking for leaks, cleaning or repairs of pipes etc. If you are
using combustible gases including oxygen, appliance may
have the risk of fires and explosions.
• Do not discharge the refrigerant into the atmosphere.
• If refrigerant leaks, ventilate the room.
• Always check for gas (refrigerant) leakage after installation or
repair of appliance.
• Be cautious not to get injured by the sharp edges while in-
stalling the appliance or taking it out of its packaging.
• Ensure that you carry by the chassis when you lift the unit.
• This appliance should only be transported by two or more peo-
ple holding the appliance securely.
• Safely dispose of packing materials such as screws, nails or
batteries using proper packaging after installation or repair.
• To avoid nitrogen entering the refrigerant system in a liquid
state, the top of the cylinder must be higher than its bottom
when you pressurize the system.
• The tubing shall be protected to the extent that it will not be
handled or used for carrying during moving of the appliance.
• Ventilation system have to be installed in the space when ap-
pliance with R32 is using for cooling of electric equipment.
• Do not use the appliance for special purposes, such as pre-
serving foods, works of art, and etc. It is an appliance for con-
sumer purposes, not a precision refrigerant system. There is
risk of damage or loss of property.
• Do not install the unit in potentially explosive atmospheres.
Refrigerant (for R32 Only)
WARNING
• The appliance shall be stored in a well-ventilated area where
the room size corresponds to the room area as specified for
operation.
!
• The appliance shall be stored in a room without continuously
operating open flames (for example an operating gas appli-
ance) and ignition sources (for example an operating electric
heater).
• The appliance shall be stored so as to prevent mechanical
damage from occurring.
• Do not use means to accelerate the defrosting process or to
clean, other than those recommended by the manufacturer.
• Do not pierce or burn.
• Be aware that refrigerants may not contain an odour.
• Pipe-work shall be protected from physical damage and shall
not be installed in an unventilated space, if that space is
smaller than the minimum floor area.
Minimum Floor Area
• m: Total refrigerant amount in the system
• Total refrigerant amount: Factory refrigerant
Additional refrigerant amount
• Do not use copper pipes which are deformed. Otherwise, the
expansion valve or capillary tube may become blocked with
contaminants.
• Ducts connected to an appliance shall not contain an ignition
source.
• The installation of pipe-work shall be kept to a minimum.
• When installing or relocating the appliance, consult with a quali-
fied technician to set up the appliance. The appliance should not
be installed by someone without proper qualifications.
• Operating the appliance while it is disconnected to the pipe
could result in explosion and damage. Use the appliance after
connecting it to the pipe once the appliance has been relo-
cated and the refrigerant circuit repaired.
• Do not place a heater or other heating appliances near the
power cable.
CAUTION
To reduce the risk of minor injury to persons, malfunction, or
damage to the product or property when using this product, fol-
low basic precautions, including the following:
• Install at places where it can endure the weight and
vibration/noise of the outdoor unit.
• Install the appliance in a place where the noise from the out-
door unit or the exhaust air will not inconvenience the neigh-
bors. Failure to do so may result in conflict with the neighbors.
• Ensure the appliance is installed level. Otherwise, it may
cause vibration or water leakage.
• Install the drain hose properly for the smooth drainage of
water condensation.
• Do not touch the leaking refrigerant during installation or re-
pair.
