1. Turn OFF the power, wait approximately one minute, and then
open the cover. Remove the filter, replace it with a new filter, close
the cover, and then firmly tighten the handle screw. This
completes the filter replacement.
2. As a general guide to the replacement frequency, check the color
of the filter regularly and replace it when the color shows a
noticeable change.
3. It is recommended that the filter be replaced soon after the color
changes noticeably in order to maintain the Fan's performance.

Warranties.
(a) Exclusive Warranty. Omron’s exclusive warranty is that the Products will be free from defects in materials and workmanship
for a period of twelve months from the date of sale by Omron (or such other period expressed in writing by Omron). Omron
disclaims all other warranties, express or implied.

replacement thereof) the non-complying Product, (ii) repair the non-complying Product, or (iii) repay or credit Buyer an amount
equal to the purchase price of the non-complying Product; provided that in no event shall Omron be responsible for warranty,
repair, indemnity or any other claims or expenses regarding the Products unless Omron’s analysis confirms that the Products
were properly handled, stored, installed and maintained and not subject to contamination, abuse, misuse or inappropriate
modification. Return of any Products by Buyer must be approved in writing by Omron before shipment. Omron Companies shall
not be liable for the suitability or unsuitability or the results from the use of Products in combination with any electrical or

Suitability of Use.
Omron Companies shall not be responsible for conformity with any standards, codes or regulations which apply to the
combination of the Product in the Buyer’s application or use of the Product. At Buyer’s request, Omron will provide applicable
third party certification documents identifying ratings and limitations of use which apply to the Product. This information by itself
is not sufficient for a complete determination of the suitability of the Product in combination with the end product, machine,
system, or other application or use. Buyer shall be solely responsible for determining appropriateness of the particular Product
with respect to Buyer’s application, product or system. Buyer shall take application responsibility in all cases.

thereof.

it to actual application requirements. Actual performance is subject to the Omron’s Warranty and Limitations of Liability.
Change in Specifications.
Product specifications and accessories may be changed at any time based on improvements and other reasons. It is our
practice to change part numbers when published ratings or features are changed, or when significant construction changes are
made. However, some specifications of the Product may be changed without any notice. When in doubt, special part numbers
may be assigned to fix or establish key specifications for your application. Please consult with your Omron’s representative at
any time to confirm actual specifications of purchased Product.

assumed for clerical, typographical or proofreading errors or omissions.
