Portable air conditioner unit –
BT-12000RC Operating Instructions
Also called – room air conditioner, mobile air conditioner
This mobile room air conditioner adjusts the temperature and humidity in a room. Its flexibility makes it easy to use in different
applications and to cool various rooms. This mobile air conditioner unit is designed to cool office or computer rooms. This air
conditioner allows you to control the 4 factors that determine optimal comfort in a room -
1. Humidity rate- humidity in a room can cause a sensation of heat in the summer. The air conditioner not only cools the
temperature but dehumidifies the air as well.
2. Temperature-The main function of an air conditioner is to draw hot air out of the room.
3. Air purity-The air filter removes dust particles from the room air creating a healthier room atmosphere.
4. Airflow-The air conditioner regulates the airflow allowing the flow to be directed and ensuring optimal air circulation.
Note: Avoid being directly in front of the cold airflow and do not direct it onto people. To ensure the optimal efficiency of the
unit, we advise you keep doors and windows closed, and to take into account the surface of the walls and windows exposed to
sunlight. In this case and in order to optimise the functioning of your mobile air conditioning unit we recommend partially closing
the window coverings.

ontinuous Drain Features
There are two continuous drain features in this mobile air conditioner unit
1. The drain at the side of the unit (A) runs through the exhaust hose and offers continuous drainage via a built-in pump.
When the cap is on the drain at the bottom of the unit (B) and the condensation tank fills to capacity the drain (A)’s
pump will automatically turn on and pump the condensation out of the unit. If the exhaust hose is installed more than
5.9 feet above the ground drain (A)’s pump will not work and the condensation must be drained from drain (B)
2. Drain (B) is located at the bottom rear of the unit and offers continuous drainage via gravity. To use drain (B) place a
shallow pan underneath the drain outlet and remove the rubber cap. In order to avoid spilling water while moving the
unit from room to room please drain the condensation via drain (B) before moving the unit. In addition whenever you
will not be using the unit for an extended period of time such as at the end of the season again use drain (B) to make
sure the condensation is completely drained from the unit

indicated by the blinking air conditioner indicator light on the control panel and the fan will continue to operate and
circulate the air.
•SLEEP ONTROL FUN TION: This function is designed to: (a) gradually increase the thermostat temperature and
hence the room temperature as you fall asleep and (b) shut the unit off. To set the ‘’Sleep Comfort’’ mode first press
the sleep button. Then set the number of hours from the current time that you would like the unit to remain on by
pressing the timer button until the desired hours are indicated on the LED display. The temperature setting may be
varied in the ‘’Sleep Comfort’’ mode by pressing the ‘’UP’’ or ‘’DOWN’’ buttons. For each press the temperature will be
increased or decreased by 1°C. During the course of this cycle the microprocessor memory will gradually raise the
preset temperature 2° - 3°C over a two hour period maintain that temperature for the balance of the time set and then
shut the unit off
•L. .D DISPLAY: Indicates the room temperature and the timer and temperature settings. The units LED displays the
room temperature as son as the power is turned on and after the timer or temperature is set
•ALARM INDI ATOR LIGHT: This light will illuminate and this unit will shut off when the condensate tank is full and the
unit cannot drain. The light will remain on and the unit will remain off until the condensation is drained through Drain
(B). Please refer to the trouble shooting section at the bottom of the instructions

•DEHUMIDIFIER INDI ATOR LIGHT: Press the ‘’FUNCTION’’ button to select the dehumidification mode. When the
dehumidification mode is on the temperature buttons and the fan speed buttons do not function and the fan will operate
on low speed. The dehumidifier indicator light will illuminate and stay solid while the unit is dehumidifying. When the
humidity in the room is 50% or lower the compressor will not run the unit will not dehumidify and the dehumidifier
light will blink. Remember the exhaust hose does not need to be used in dehumidifier mode
NOTE: This unit has a three-minute compressor delay protection circuit. Thus the compressor may take up to three minutes to
start from either being switched on or when changing between the dehumidification and air conditioning functions.
If there is a power interruption while the unit is operating, the unit will not turn back on automatically when the
power is restored. The unit must be turned back on manually. The unit is designed with this safety feature to
protect the compressor.

Before cleaning the unit, turn it off and unplug it from the outlet. For safety reasons, never wash the conditioner
Exterior Surfaces of the Unit
•Clean the air conditioner by using a damp sponge and dry it with a clean soft cloth
•Never use alcohol or any product containing solvents
Air Filters
The air filters located on the back of the unit collect dust contained in the air. The air conditioning unit must A WAYS be used
with the air filters
•The build up of dust reduces the efficiency of the air conditioner. Therefore the air filters must be cleaned every two
weeks and more often if the machine operates in a dusty atmosphere
•If the filters are obstructed the air conditioner will be less efficient
•Each air filter has a tab in the centre and is secured to the unit by two clips on the top and two clips on the bottom of
the filter. Remove the air filters with the unit switched off by pulling the tab towards you
•Clean the air filters with a vacuum cleaner. If the filters are very dirty you can wash them in warm water (never use hot
soapy water). Make sure that the air filters are completely dry before putting them back into the unit
•Do not bend the filters

length of 10’
The unit is positioned to close to a wall or
an object
The unit should be at least 1½ away from
any wall or object
The flap vent obstructs the wall exhaust Use the screen instead of the flap vent for
wall exhaust
The ceiling or the basement does not
have ample ventilation
The unit will overheat the exhaust pipe
and cannot fully vent
The ‘’timer off’’ function has been
activated
Push the power button to turn the unit
back on
The air conditioner / dehumidifier
ED indicator light blinks
In the a/c function the ambient
temperature has reached the set
This is normal. Set the temperature lower

temperature and therefore the
compressor has shut off
to turn the compressor back on
In dehumidifier mode the humidity in the
room is 50% or lower and therefore the
compressor is not running
This is normal
The ED display shows the unit is set,
but the unit is not running The units ‘’timer on’’ feature is activated
This is normal
Push the Power button to turn the unit on
and deactivate the ‘’timer on’’ feature

the drain hose is no more than 5.9 feet
above the ground. If drain (A) still does
not work the condensate must be drained
through drain (B). After draining the tank
you should be able to restart and use the
unit
