(1) After the snow protection hood is installed, the noise at the air outlet side may slightly increase.
Therefore, it is necessary to carefully consider the air discharge direction when installing.
(2) Be sure to tighten the snow protection hood securely to the top panel and side panel of the outdoor
unit with the supplied screws (accessories). Not doing so may lead to noise caused by vibrations.

(4) Do not install other outdoor units in the direction of air outlet. If the air blown out of the snow protection
hood is sucked into the other outdoor unit, it may cause a malfunction.
(5) The wind loads which the outdoor unit receives change by attaching the snow protection hood. The
required installation strength will also change in a strong wind. Therefore, recheck the strength of the
anchor bolts of the outdoor unit.
(6) When a snow protection hood is installed, cooling/heating performance may be slightly lower
depending on the usage conditions.
