To start unit
If your air conditioner is installed and plugged into a properly grounded

Mode control (QuietMaster ‘K’ and Heavy Duty)

The upper dial (Figure 5) allows you to select cooling at four different
speeds, as well as Fan Only (Models SL28 and SL36 only have three
cooling speeds.).
Off - to turn the unit off.
High Cool - for quick cooling.
Medium Cool - to maintain a de sired temperature.
Low Cool - when cooling demand is low.
Sleep Setting - for nighttime use, or when cooling demand is low.
Fan Only - to circulate air in the room without the compressor coming on.
The Fan Only setting can also be used with the Exhaust air set ting to r emove
stale air or smoke from the room; or it can be used with the Fresh Air setting
to bring outside air into the room. This is especially useful in the spring and fall
when cooling may not be nec es sary. The Fresh Air and Exhaust controls
are in the upper air discharge area. The center po si tion of this control is the
normal, or closed position, which recirculates air for maximum per formance
in the cool ing mode (See Figure 9).

Mode control (Twintemp)

This dial allows you to select cooling or heat ing at three different speeds,
as well as Fan Only (Figure 6).
Off - to turn the unit off.
High Cool or High Heat - for quick re sponse.
Medium Cool or Medium Heat - to main tain a de sired temperature.
Low Cool or Low Heat - for nighttime use, or when demand is low.
Fan Only - to circulate air in the room without the compressor coming on.
The Fan Only set ting can also be used with the Exhaust air set ting to
re move stale air or smoke from the room, or it can be used with the Fresh
Air setting to bring outside air into the room, es pe cial ly in the spring and
fall when cool ing isn’t nec es sary.
The Fresh Air and Exhaust con trols are in the up per air discharge area
(see Figure 9, page 7). The cen ter position of this control is the normal, or
closed po si tion, which re cir cu lates air for max i mum per for mance in the
cool ing m ode.
NOTE: You may notice an odor when fi rst ac ti vat ing the heat when the
electric heat el e ment comes on. This is due to dust burning off that may
have gath ered on the coil during the sum mer. This is normal.

Temper atu re co ntro l

The bottom dial on the control panel is the thermostat. Turn it clock wise
for cooler temperature and counterclockwise for warmer.

Money Saver® switch

This rocker switch can be depressed to either Yes or No. In the Yes position
you will get the most eco nom i cal operation. Both the fan and com pres sor
will cy cle on and off to geth er, main tain ing the se lect ed tem per a ture at a
more con stant lev el and re duc ing the hu mid i ty more ef fi cient ly in the cooling
mode. This control will only op er ate when the unit is in cooling or heating
mode. In the No position, the fan will run con stant ly as long as the unit is
in the cooling or heat ing mode.
NOTE: The YS09 is a 115 volt model and does not provide adequate heat
below 37°F (3°C). This prod uct is designed for warm climate ap pli ca tions.
