PRODUCT OPERATION
THEORY OF OPERATION
OPERATING MODES
The Whirlpool 10,000 BTU Portable Room Air

•
Mode: In the Cooling Mode the
customer can adjust the temperature setting
from 90°F to 64°F. The actual temperature
be displayed after the temperature ad-
will
justment
has been made. The compressor
and condenser fan motors cycle on or off
together. They will cycle on when the room
temperature is greater than 1°C, (approximately
point
2°F), away from the temperature set
and off at the same intervals below set
point. High, Low, or Auto fan speed may be
selected.

may be increased or decreased
•
Mode: The unit starts in the cooling
Dry
mode for three minutes to determine the
room air temperature at the thermistor. The
control creates a set point 3°F (1.5°C) cooler
room temperature and then operates
than
in the cooling mode with the evaporator fan
operating at low speed. This 3°F (1.5°C) differential
is needed to allow the compressor
to run long enough to chill the evaporator.
Set point temperature may be increased or
decreased by 4°F (2°C). Only the actual
temperature will be displayed.
Only Mode: In the fan only mode, only

•
the evaporator fan motor will run. High, Low
or Auto fan speed may be selected.
Auto Fan: The speed will be set automati-
•
based on room temperature. If the tem-

is greater than 6°F (3°C) above set
the fan will run on high speed until set

motor opens the air louver to permit air from
the evaporator to flow into the room. Hold-
the fan speed button for three seconds
ing
or pressing the Swing button on the remote
will start the air door cycling up and down.
CONDENSATE WATER
MANAGEMENT
Condensate water from the evaporator drains
down into a sump in the unit base. As the water
level rises, the low water level switch closes, and
the water pump begins to circulate the water to
the top of the condenser. The water flows down
over the warm condenser, and is evaporated.
The water vapor is carried out the exhaust
duct. If the high water level switch closes, the
compressor and condensor fan motors shut
off, and the water full indicator LED lights. The
water must be drained manually.

COMPRESSOR PROTECTION
FULL WATER WARNING
The control protects the compressor by not
allowing a compressor restart for 3 minutes.
This delay will occur when moving through the
operating modes with the remote or keypad or
if there are rapid temperature changes at the
thermistor.
DE-ICE PROTECTION
A de-ice thermistor is mounted on the end of
the evaporator in a tube brazed to the tubing
loops. When the de-ice thermistor senses 25°F
(–4°C) for a continuous 30 seconds, the compressor
a buzzer sounds. When the de-ice thermistor
senses higher than 41°F (5°C), normal operation resumes.
and condenser fan motors stop and
When the high water level switch closes, the
Water Full LED will flash and all operation will
cease. The consumer must manually drain the
sump by pulling the drain plug over a drain.
THERMISTOR FAILURE DEFAULT
To provide some cooling operation in the event
of a thermistor failure, the control will default
to the following settings if a thermistor is determined to be shorted or open.
