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.
Blocked filters must be cleaned frequently to maintain cooling
& heating performance
To clean the two plenum filters, first remove them both from
the plenum by pulling them out of the assembly.
Fig 17 plenum filter when removed
The state of the filters can be ascertained from its appearance,
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, particulalry to
young children and the elderly. Ensure that filters are cleaned
in a safe and well ventilated area
If a more thorough clean 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 Aircommand.
II. Mounting bolts
Aircommand 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 van is in constant use.
III. Compressor mounts
Ensure that the rubber mounts on the compressor are checked
every 12 months and more often with frequent travelling. If
the top mount looks very worn or there is no rubber left
between the top washer and the compressor foot (metal on
metal contact possible) then the rubbers need replacing.
IV. Storage
The air conditioner should be run on a routine basis to ensure
the components remain in working order.
If the van is in storage or is to remain unoccupied for an
extended length of time it is recommended that the air
conditioner is allowed to run uninterrupted for 20-30min once
every six months.
