T
he 18,000 BTU horizontal air
conditioner, NSN 4120-01-327-
1316, used on many commo
shelters is not self-maintaining.
It is not a “run it and forget
it” piece of equipment. It relies
on you, the operator, to keep it
up and running.
Care for your cover.
The con-
denser cover is the clothing of
your AC unit and it looks like
many of your units are living in
poverty! Roll the cover up and
down and make sure the two
ties are attached and the snaps
are still there. Look for mildew,
tears and excessively worn
edges. If it’s dirty, wash it! And
then, give it a coat of rubber
preserver. Make sure the screws
that hold it in place are tight.
Love your louvers.
The return air louver
and the conditioned air
supply louver must
operate easily without
stiffness or binding. If
they’re stiff or they
bind, clean them and
lubricate them like
your TM calls for.
Treat your tubing to TLC.
The
condenser drain tubing carries
waste water out of your unit,
unless it is not connected or leaks.
In either of those cases, the water
puddles at the bottom of the AC
unit and causes corrosion. Make
sure the tubing is connected and
in good shape. Look for block-
ages that need to be cleared out.
Be filter friendly.
Air filters
catch sand and dirt. That’s their
job. Your job is to keep them
clean so they can do their job.
You have the same job for the
mist eliminator and the con-
denser coils. If you’re operating
in sand, this job is a daily one!
If available, 30 psi of com-
pressed air will help with the
cleaning. Wear safety goggles if
you use compressed air.
Be a pal to your panels.
Panels, covers, screens and
guards need to be kept clean.
Dirt on the outside of your unit
will slither its way to the inside
of your unit. Wipe your unit
down daily! There is no such
thing as a dirt-free environment
and where there is dirt, there is
dirt on the AC unit.
Here are five
maintenance areas
that should not
be neglected!
