For QuietMaster Programmable models only:
You can reset the circuit board by pressing the “Moneysaver” button and
the “Check Filter” button at the same time. The LED (small red light) for
the Check Filter will begin blinking. Once this occurs, turn the unit off by
pressing the On/Off button once and then unplug the unit. Finally, plug the
unit back in and turn it on by pressing the On/Off button once. All settings
revert back to the factory default settings.

This is a warm weather appliance
Your air conditioner is designed to cool in warm weather when the outside
temperature is above 60°F (16°C) and below 115°F (46°C), so it won't
cool a room if it is already cool outside.

If you want to cool a room in the
spring or fall, touch
Fan Only
and set the
Fresh Air/Exhaust
control to
Fresh Air
. This will bring in a supply of cooler outside air.
Condensation is normal
Air conditioners actually pump the heat and humidity from your room to the
outside air. Humidity be comes water, and your air conditioner will use most
of the water to keep the outside coil cool. If there is excessive humidity, there

of the water to keep the outside coil cool. If there is excessive humidity, there
may be excess water that will drip outside. This is normal op er a tion.
Frosting
This usually occurs because of insufficient airflow across the coils, a dirty
filter, cool damp weath er, or all of these. Set unit to Fan Only and the frost
will disappear. Setting the thermostat a little warmer will probably prevent
the frosting from recurring.

units are
designed to operate as quietly as possible. An air conditioner mounted in
a wall is quieter than one mounted in a window. It is important to ensure
that the chassis seal gasket is properly installed (refer to installation
instructions).

Cleaning your air conditioner
The decorative front and the cabinet can be cleaned with warm water and
a mild liquid de ter gent. The indoor coil can be vacuumed with a dusting
attachment if it appears to be dirty. The outdoor coil can be gently sprayed
with a hose if you can get to it. If not, you might call your dealer for a
more thorough cleaning when needed. The air fi lter should be inspected
weekly and cleaned if needed by vacuuming with a dust attachment or by
cleaning in the sink using warm water and a mild dishwashing detergent.
Dry the fi lter thoroughly before reinstalling. Use caution– the coil surface
can be sharp.

Heat pumps operate differently
If your unit is a "Y", or heat pump model, there are some things that you
will want to be aware of.

2. If the outdoor temperature drops below 37°F (3°C), your heat pump
will automatically turn on the electric re sis tance heat. When the
temperature rises to 40°F (4°C), the compressor will resume the
heat pump operation. If your unit is a 115 volt model (YS09), it is
designed for use in warmer climates and has no electrical heat
feature, and will not provide adequate heat below 37°F (3°C).

Window Installation Kits
TwinTemp or Heat/Cool room air conditioners are shipped without window
mount ing hard ware because they are seldom mount ed in the window. For
those in stanc es when these units are being mounted in a window, there
are window installation kits available. Depending upon the chassis size for
which an in stal la tion kit is desired, order:
