!Warning:
Make sure that the voltage rating printed on the AC adapter is
identical to your local line voltage. The only way to turn power off
completely is by disconnecting the AC adapter from the main input
voltage.
 Protect the AC adapter from contact with liquids.

 Before Connecting Humidity chamber cord to main line cheque
proper earthling of main Input line, its most important.
 This product is intended for indoor Use only.

!Warning!
This unit contains no user-serviceable
parts. Do not open the Humidity chamber switch panel/control Panel,
outer inner chamber without permission of supplier/distributer /manufacturer, as this voids the
manufacturer’s warrantee.
