2) This unit should not be installed in such a way that the wind blows directly at the back of the unit.
3) The installation of this product will reduce the unit's capacity by approximately 2% - 3% and increase the outdoor unit's noise level by approximately 1dB - 2dB.
4) Use this product only if there is no obstruction on either side or above the outdoor unit (discharge air will be blocked). This could result in a short cycle.

INQUIRE WITH THE DEALER OR SPECIALIST ABOUT INSTALLATION
Water leaks, electric shocks, fires, and other hazards may occur if the user installs the product incorrectly.
CAREFULLY INSTALL THE PANEL IN ACCORDANCE WITH THIS INSTALLATION SHEET
Incorrect installation could result in a water leak, electric shock, or fire, among other things.
POLYETHYLENE BAGS SHOULD NOT BE LEFT IN THE REACH OF CHILDREN
Putting a polyethylene bag over one’s head will close off your breathing pathways, potentially resulting in suffocation.
TO AVOID CONDENSATION, SECURELY APPLY HEAT INSULATION TO THE REFRIGERANT PIPE
Condensation on the surface of pipes, as well as dewdrops on the ceiling, floor, or valuables, might develop if heat
insulation is insufficient.
USE ONLY SPECIFIED ELECTRIC WIRES WITH CURRENT CAPACITY IF ELECTRICAL WORK IS REQUIRED.
Unsuitable wire may cause an electric leak, overheating, or fire.
SECURELY COMPLETE DRAIN PIPING WORK IN ACCORDANCE WITH THE INSTALLATION MANUAL TO
AVOID CONDENSATION.
If the piping work is incorrect, a water leak may occur, causing the ceiling, furniture, and other items to become wet.
When the outdoor unit fan enters low speed rotation mode with the fan controller turned on, this Snow Guard prevents reverse rotation. It is also used to
protect the fan when strong winds, such as a typhoon or wind blowing through tall buildings, strike the air outlet directly. Furthermore, installation of this product
is required when cooling operations are to be carried out in outside-air temperatures of -5°C or lower (down to -15°C).
