ENGLISH
Installation must be carried out by a qualified installer. Do not attempt to repair, move, modify or reinstall the unit on your own since such act may cause fire, electric shock or water leakage.
Install the unit in a place where it is strong enough to hold the product weight. When installed in place where it is not strong enough to withhold the product weight, the unit could fall and cause injury.
The unit should be installed in accordance with the National Electrical regulations. Check if the voltage and the frequency of the main power supply are those required for the unit to be installed and check the connection. Avoid the use of an extension cord and do not share the power outlet with other appliances. Incomplete connection, defective insulation or exceeding the permissible current may cause electric shock or fire.
Use the specified wires to connect the indoor and outdoor units securely and attach the wires firmly to the terminal block connecting sections so that the pressure is not applied to the sections. Inappropriate connection and fixing could cause fire.
Attach the electrical cover to the indoor and outdoor unit securely without any gaps.
If there are any gaps, there is potential risk of fire or electric shock due to dust or water.
Make sure to use the part provided or specified parts for the installation work. The use of defective parts could cause an injury or leakage of water due to a fire, an electric shock, the unit falling, etc.
Make sure that the refrigerant gas does not leak after completing the installation.
If the refrigerant gas of the indoor unit leaks and comes into contact with the fan heater, space heater or stove, harmful gas will be generated.
Ensure that the national safety code requirements have been followed for the main supply circuit. Ensure that a proper ground wire is in place.
Do not connect the ground to a gas pipe, water pipe, lightning rod or telephone grounding. Defective grounding could cause electric shock.
Do not install the unit in a place with direct sunlight, dangerous substances or where it is exposed to inflammable gas leakage to prevent explosion, fire or personal injury.
Perform the installation securely referring to the installation manual. Incomplete installation could cause personal injury due to fire, electric shock and water leakage or from the unit falling.
Before connecting the power plug and power receptacle check for dust, loose or blocked. Make sure that plug is fully inserted. Dusted power plug, blocked or loosened power receptacle may cause fire or electric shock. Exchange the power receptacle if it is loose.
Check first the following situations before starting the operation during the installation.
-The pipe must be properly connected and make sure there is no leakage.
-Service valves must be open. If compressor is operated with the service valve closed, excessive pressure may damage parts of the compressor.
If leakage occurs on any of the connection, air inflow may also cause excessive pressure that could lead to explosion.
