2. Installation Work
(1) After the snow protection hood is installed, noise at the air outlet side may slightly increase. Consider
carefully the air discharge direction when installing.
(2) 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) Avoid obstacles in the direction of air discharge from the snow protection hood to prevent short circuit
RUDUHGXFWLRQLQWKHDLUÀRZUDWH
(4) Do not install other outdoor units in the direction of the air outlet. If the air blown out of the snow
protection hood is sucked into the other outdoor unit, it may cause a malfunction of the unit.
(5) Double-check the strength of the anchor bolts of the outdoor unit. The wind loads on the outdoor unit
change by attaching the snow protection hood. The required installation strength also changes in
strong wind.
