3.5 Removing of the Fan Fixing Parts
Fan bases are fixed to the unit frame with spring vibration insulators to prevent noise and vibration. Since this situation
may cause damage to the unit by undesirable vibrations during shipment, the fan bases are fixed to the unit frame via
a fixing sheet at the factory. The sheets must be removed before the fans are operated.
The units may be damaged if operated without the fixing sheet of fan Insulators
removed. AERA is not responsible for any damages that may occur due to the failure to remove the sheets.
