Installation
Warning This unit is not intended for use on boats or recreation
vehicles.
Places to Install
Refer to the Installation Instructions before using the air purifier.
1. Plug power cord into its own dedicated properly grounded outlet.
2. Make sure the power cord is positioned where it does not cause a tripping hazard and will
receive adequate ventilation. Do not install your air purifier directly next to furniture or
objects that could block the vent openings.
3. Make sure that any items that could be blown over or damaged by the air flow from the fan
are out of the airflow path.

How to Use
Cleaning the Air Purifier
• The air filter should be cleaned on a regular basis. Depending on the air quality, more frequent
cleaning may be required.
The filter can be washed in warm water using a mild detergent.
Allow the filter to completely dry before reinstalling.
Use after enough air circulation when cooking.
• Certain foods can give off oils during cooking which can shorten the life of the filters. When frying
meats or fish, use other methods to exhaust the odors from the home (such as an exhaust fan or
an open window). Once the majority of the odors have been exhausted, your air purifier can then
be used to remove any residual odors that remain. This will insure maximum life of your filters.
Do not stay too closed when sleeping.
• To prevent drafts while you're sleeping, do not install the air purifier closer than 3 feet from sleep
areas.
Do not place in the corner edge.
• Do not place directly next to furniture or objects that could block the vent openings. Avoid installing
in inclosed areas (such as the corner of a room) where air flow to the rest of the room will be
restricted.
Ensure air circulate 30 minutes at least everyday.
• Use the air purifier for at least 30 minutes a day to ensure a fresh air flow. Regular cleaning
maintenance will assure better air flow.
