MAINTENANCE
I. Plenum Filters
The plenum filters are the only parts that require routine maintenance. They
must be cleaned periodically to ensure that they do not become clogged with
dust and other particles and not covered by Warranty.
To clean the two plenum filters, first remove them both from the plenum by
pulling them out of the assembly.
The state of the filters can be ascertained from its appearance, the filters are
translucent, and if they appear clogged then they should be cleaned. Generally
the filters can be cleaned sufficiently by tapping them together to shake loose
the dust and particles trapped inside.
WARNING
Airborne particles can pose a health risk, particularly to young
children and the elderly. Ensure that filters are cleaned in a safe and
well-ventilated area.
If a more thorough cleaning is required then the filters can be washed out
using warm soapy water. Care must be taken to avoid ripping the fabric.
The filters should be cleaned every two weeks or more when in use. Prolonged
use, higher concentrations of airborne particles, and various other factors may
result in the filters needing to be cleaned more often.
Replacement filters can be ordered directly from Atwood Mobile Products, LLC by calling 866-869-3118.
II. Mounting Bolts
Atwood suggests that the hold down bolts are initially checked for tightness
within the first 3 months of installation, and thereafter every 12 months if the
vehicle is in constant use.
III. Storage
The air conditioner should be run on a routine basis to ensure the components
remain in working order.
If the vehicle is in storage or is to remain unoccupied for an extended length of
time it is recommended than the air conditioner is allowed to run
uninterrupted for 20-30min once every six months.
