•
Before touching electrical parts, turn off the unit.
•
The circuit must be protected with safety devices in accordance with local and national codes, i.e. a
circuit breaker.
•
Securely fasten the outdoor unit terminal cover (panel). If the terminal cover/panel is not installed
properly, dust or water may enter the outdoor unit causing fire or electric shock.
•
When a fire occurs, cut off the power supply immediately.
CAUTION
!
•
Do not touch the switch with wet fingers. Touching a switch with wet fingers can cause electric shock.
•
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.
•
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 can be used by children aged from 8 years and above and persons with reduced
physical, sensory or mental capabilities or lack of experience and knowledge if they have been given
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.
•
Use shielded wires of operation line between the indoor and the outdoor unit. And connect the shielded
part to the earth screw in the electrical box of the indoor unit as shown in the Fig. 1.
