supervision or instruction concerning use of the appliance in a safe way and understand the hazards
involved. Cleaning and user maintenance shall not be made by children without supervision.
•
Wear adequate personal protective equipment (protective gloves, safety glasses,...) when installing,
maintaining or servicing the system.
•
The heat exchanger fins are sharp enough to cut. To avoid injury, wear gloves or cover the fins while
working around them.
•
Do not touch the refrigerant pipes during and immediately after operation as the refrigerant pipes may
be hot or cold, depending on the condition of the refrigerant flowing through the refrigerant piping,
compressor, and other refrigerant cycle parts. Your hands may suffer burns or frostbite if you touch the
refrigerant pipes. To avoid injury, give the pipes time to return to normal temperature or, if you must
touch them, be sure to wear proper gloves.
•
Install drain piping to ensure proper drainage. Improper drain piping may result in water leakage and
property damage.
•
Insulate piping to prevent condensation.
•
Be careful when transporting the product.
•
Do not install the air conditioner or heat pump in the following locations:
○ Where a mineral oil mist or oil spray or vapor is produced, for example, in a kitchen. Plastic parts may
deteriorate and fall off or result in water leakage.
○ Where corrosive gas, such as sulfurous acid gas, is produced. Corroding copper pipes or soldered parts
may result in refrigerant leakage.
○ Near machinery emitting electromagnetic waves. Electromagnetic waves may disturb the operation of
the control system and cause the unit to malfunction.
○ Where flammable gas may leak, where there is carbon fiber, or ignitable dust suspension in the air,
or where volatile flammables such as thinner or gasoline are handled. Operating the unit in such
conditions can cause a fire.
•
Take adequate measures to prevent the outdoor unit from being used as a shelter by small animals.
Small animals making contact with electrical parts can cause malfunctions, smoke, or fire. Instruct the
user to keep the area around the unit clean.
•
This appliance is not intended for use by persons (including children) with reduced physical, sensory or
mental capabilities, or lack of experience and knowledge, unless they have been given supervision or
instruction concerning use of the appliance by a person responsible for their safety. Children should be
supervised to ensure that they do not play with the appliance.
NOTES:
•
The air in the room should be renewed and the room ventilated every 3 or 4 hours.
•
The indoor unit should be positioned where the unit and interunit wires (outdoor to indoor) are at least
3.3ft (1m) away from any televisions or radios. (The unit may cause interference with the picture or
sound.) Depending on the radio waves, a distance of 3.3ft (1m) may not be sufficient to eliminate the
noise.
•
Dismantling the unit, treatment of the refrigerant, oil and additional parts must be done in accordance
with the relevant local, state, and national regulations.
•
As maximum allowable pressure is 4.15MPa, minimum allowable pressure is 2.21MPa, the wall
thickness of field-installed pipes should be selected in accordance with the relevant local, state, and
national regulations.
