De Economy Wise
These economy rips con help maximize comforr ond
reduce power consumption.
• Set your cooling level or the setting consistent with
the comfort level and economy you desire Once
you hove determined the most economical com
fort setting, leave the setting alone.
• Keep the filter cleon! Normally, cleaning every
30 days is sufficient, but the filter is very efficient in
removing airborne particles, and inspection may
indicate the need for more frequent cleaning
• Use drapes, shades, Venetian blinds, awnings, etc,
to prevent direct sunlight from hearing the raom.
Do not obstruct front of unit.
• Stort your unit before outside temperature,
caaKing heat, ar gatherings of people moke the
room uncomfortoble This ovoids the initiol period
of discomfort while the unit lowers the temperoture and humidity to your desired level.
AIR DIRECTION
An air discharge grille is locoted near the top of your
room air conditioner to direct air for gentle, droft-free
cooling Tip the grille for upward or horizontal oirflow
Two levers protruding thru grille allow movement of
louvers to the left or right
As on optional feoture for installations mounted
high on a wall, the discharge grille may be inverted
to direct cool air downward. See directions in the
Installotion Instructions or osk your Corrier dealer
about the proper procedure.
Cleaning and
Maintenance
(Turn air conditioner off and remove plug from wall
receptacle.)
Clogged filters con result in reduced cooling, inter
mittent operotion, ice buildup on indoor (evoporotor) coil, or blown fuses. Take o few minutes each
month (more often if needed) to inspect unit filter
ond clean os required.
1 Press down on top corners of grille ond pull out-
word. Lift grille from bottom retoining clips.
2 Remove filter from plostic pins in bock of the grille
Vocuum or wash filter in warm woter Shake filter
vigorously to remove excess woter and reploce
on plastic pins (be sure the filter completely covers
the foce of the grille).
3. Set grille on retoining clips and push top of grille
firmly onto cabinet
Coil — Cleon cooling coil gently with vacuum
cleaner. Use a soft cleaning brush attachment. If you
do not hove this type of vocuum, use o soft bond
