Safety precautions
Neatly arrange the wires in the electrical parts to make sure that electrical cover is closed securely without any gaps.
If the cover is not properly closed, heat may be generate on the electrical terminal and cause electric shock or fire.
Make sure to use the provided or specified parts with the specified tools for installation.
Failing to do so may cause product falling, water leakage, fire or electric shock.
In any case of refrigerant leakage, make sure to ventilate.
If the refrigerant gas comes in contact with fire, harmful gas will be generated.
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.
Make sure to perform grounding work.
Do not connect the ground wire to a gas pipe, water pipe, lightning rod or telephone grounding. Improper grounding
could cause electric shock.
Do not install the product in a place where it is or might be exposed to inflammable gas leakage.
When the gas leaks and gets accumulated around the product, it may cause fire.
Installation work must be done according to the instruction in this installation manual.
Improper installation may cause water leakage, electric shock or fire.
When inserting the power plug, make sure to insert it fully and check that power plug and a consent does not have any
dust, blockage or loosened part.
If there is dust, blockage or loosened part on a power plug or consent, it can cause electric shock or fire. Also, replace the
consent if it is loosened.
When installation is in progress, check the following before operating the product.
Make sure pipes are properly connected without any leakage.
Service valve should remain open. If the compressor operates with service valve closed, compressor or other parts may
get damaged due to overpressure. Also, if there is leakage on the connection part, air inflow and other matter may make
the status even more overpressured, which can cause personal injury due to explosion.
Stop the compressor before disconnecting the refrigerant pipe for pump-down operation.
If you disconnect the refrigerant pipe while compressor is operating with service valve open, air inflow will cause
excessive pressure in the refrigerant cycle that could lead to explosion and personal injury.
Do not assemble the power cord on your own, use two cables together to extend the cable length or connect the power
to a multi consent connected with other products.
Bad connection, isolation and over voltage may cause fire or electric shock.
Cut-off the main power supply before indoor unit electrical installation.
Potential risk or electric shock.
You may need to install an ELB (earth leakage breaker) depending on the installation location.
Not installing an ELB (earth leakage breaker) may cause electric shock.
