a fire. Do not plug Product into any other cord connected device, such as a power
strip, cord reel, surge protector, multiple outlet adapters or outlet-type air fresheners.
The use of such devices may create a fire hazard.
9. NEVER operate any Product with a damaged cord or plug, or if the Product has been
dropped or damaged in any manner.
10. NEVER insert or allow fingers or foreign objects to enter any ventilation or exhaust
opening as it may cause an electric shock, fire, or damage the Product. To reduce
the risk of fire, DO NOT block or tamper with the Product in any manner while it is in
operation.
11. Always place the Product on a stable, flat, level surface when operating to avoid the
chance of the Product overturning. It is recommended for floor use only. Locate the
Power Cord so the Product or other objects are not resting on it. Do not run cord
under carpeting. Do not cover cord with throw rugs, runners, or similar coverings.
Do not route cord under furniture or appliances. Arrange cord away from traffic areas
and where it will not be tripped over.
12. This Product is not intended for use in wet or damp locations. NEVER locate a Product
where it may fall into a bathtub or other water container. NEVER use Product where
flammable liquids are used or stored.
13. Care should be taken so that objects do not fall and liquids are not spilled into the
enclosures.

15. This Product is not suitable for use in agricultural facilities including areas where
livestock, poultry or other animals are confined. Please refer to National Electric Code
(NEC) Article 547-7 (2008), or applicable state or local codes or standards relating to
electrical requirements for Agricultural Buildings. THIS PRODUCT DOES NOT MEET
THE REQUIREMENTS OF NEC ARTICLE 547-7 (2008).
The power cord is equipped with a three-prong grounded plug that must be inserted into
a matching receptacle. Under no circumstances must the grounding prong be cut off the
plug. Where a two-prong wall receptacle is encountered, it must be replaced with a
properly grounded three-prong receptacle installed in accordance with the National
Electrical Code (NEC) and all applicable local codes and ordinances. This work must be
done only by a qualified electrician, using copper wire only. This plug is a safety feature;
it contains a safety device (fuse) that should not be removed. DO NOT attempt to defeat
this safety feature. Discard product if the attachment plug is damaged. To reduce the risk
of fire, electric shock and personal injury, DO NOT remove, replace, repair or tamper with
the originally supplied plug. If the Product does not function properly, it may be due to the
safety device incorporated in this plug.
WARNING: Use of a three-prong to two-prong adapter is not recommended. Improper
connection may create the risk of electric shock. Use of such adapters is not permitted
in Canada.
