2. Installation Work
(1) After the snow protection hood is installed, electromagnetic noise at the air outlet side may slightly
increase. Therefore, it is necessary to carefully consider the air discharge direction when installed.
(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 cause vibration or abnormal noise.
(3) There must be no obstacles in the air discharge direction of the snow protection hood. If there are, it
may cause a short circuit or an insuf
fi
cient air
fl
ow rate.
(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 of a malfunction of the unit.
(5) The wind loads which the outdoor unit receives changes by attaching the snow protection hood. The
required installation strength will also change in strong wind. Therefore, recheck the strength of the
anchor bolts of the outdoor unit.
(6) If the snow protection hood is installed, cooling/heating performance may be slightly lowered
depending on the usage conditions.
