NOBOCOOL NC-49DP/C
INTRODUCTION
This portable air conditioner can alter the room temperature and humidity. It has multiple functions of cooling dehumidifying
(drying) and fan ventilation, and can be moved from room to room and transported from building to building easily.
The air conditioner can maintain set room indoor air temperatures between 18°C and 32°C. The set room temperature is
displayed on the remote control and in the control panel on the unit. This does not mean that the air conditioner will necessarily
reduce the actual room temperature to the set room temperature.
HOW YOUR NOBOCOOL PORTABLE
AREFRIGER TED
AIR CONDITIONER WORKS
Hot air is blown outside through the exhaust hose, using the
window kit supplied with the air conditioner.
Air from the room is drawn into the air conditioner, cooled by
refrigeration, and blown into the room through the front grill.
Hot air must be exhausted outside the room being cooled,
or you will not cool the room.
VARIABLES INFLUENCING THE COOLING
EFFECTIVENESS OF THIS AIR CONDITIONER
The ability of the air conditioner to cool the air in your room depends
on a number of variables. The critical variables are:
1. Orientation of the room to the sun.
Rooms facing North and West are exposed to the midday and afternoon
sun, and are the hottest in the house. Rooms facing the morning sun
(East), and away from the sun (South), are the coolest in the house.
2
3. Air Draughts
4. Multi Storey Buildings
. Insulation
Insulated roofs and walls reduce the amount of heat entering the room.
Windows admit heat into the room. This heat can be reduced if the windows are
protected from the direct sun (eg by outside blinds, well lined inside curtains, pergolas, thick foliage etc).
Rooms protected from draughts are more easily cooled. Windows and doors must be kept closed.
In multi storey buildings, upper storey rooms are usually hotter and therefore harder to cool than
ground floor rooms.
SIZING
GUIDE
In general, the higher the cooling capacity (BTU/kW) of an air conditioner, the bigger the room it
will cool.
This 17,000 BTU air conditioner, subject to the variables explained in box 2, can effectively cool
rooms with a floor area of between 16 and 36 square metres.

GUIDELINES FOR OPTIMISING COOLING EFFECTIVENESS
NOBOCOOL portable refrigerated air conditioners have an independent Austalian tested cooling capacity of 5030 watts
(5.0kW) or 17,000 BTU. This is suffi cient to cool rooms up to a maximum of 36 square metres in fl oor area.
• Do not place the air conditioner or plastic window slider in direct sunlight. Close all curtains in the room being cooled.
•
For maximum cooling (COOLING MODE), set the temperature at 18°C and the fan at HIGH. After approximately
3 minutes, the compressor will turn on (indicated by the green LED marked on the control panel) and cooled
air will come out of the air outlet. Cooled air will only come out of the air outlet when the LED on the control panel
is illuminated.
•
In COOLING MODE the air conditioner will not cool unless the set temperature is below the existing room temperature.
• In COOLING MODE once the existing room temperature reaches the set temperature, the fan continues operating and
the compressor switches on and off to maintain the set temperature within the room.
• For maximum cooling output keep the exhaust hose as short and as straight as possible. Minimise bends which can
reduce the maximum cooling capacity of the air conditioner. Elevate the air conditioner if necessary.
• Make sure the air intake and outlet grills are unobstructed.
• Clean the fi lters at least once every two weeks.

TIPS ON GETTING THE MOST OUT OF YOUR NOBOCOOL
MEGA PORTABLE AIR CONDITIONER
Portable air conditioners are not designed to cool large open spaces.
To maximise the cooling effectiveness in an enclosed room:
• Turn the air conditioner on early in the day before the room heats up. It is more
efficient for the air conditioner to maintain the room at a comfortable temperature
than it is to reduce an already hot room to a comfortable level.
• Close all doors, windows, curtains and external blinds of the room being cooled.
• Seal or block major draughts.

ASSEMBLY OF EXHAUST HOSE, HOSE INLET, HOSE OUTLET, WINDOW ADAPTOR
AND WINDOW SLIDER (Fig.4)
• Fully extend each end of the exhaust hose by about 10cm and attach the hose inlet and hose outlet to opposite ends by
rotating the inlet/outlet in a counter clockwise direction approximately 3 to 4 turns, making sure that the hose wire is
well threaded into the hose inlet and outlet. The hose inlet and outlet cannot be installed unless the hose ends have been
fully extended.
• Attach the window adaptor to the hose outlet by pressure fi t.
• Clip the window adaptor into the window slider. Take care to not break the tabs on the window adaptor when
disconnecting from the window slider.
MOUNTING OF ASSEMBLED AIR EXHAUST HOSE (Fig.5)
• Take care not to damage the hose inlet when attaching/detatching at the back
of the Air Conditioner.
• Slide the hose inlet (square end) in the direction indicated by the arrow onto
the fi xing lugs on hot air outlet grill at the back of the appliance. Install
carefully and do not force.
• Place the hose outlet to the nearest window. The length of the air exhaust
hose is between 600mm to 1500mm; use the minimum length when working.
• When mounting, try to keep the air exhaust hose horizontal and do not extend
its length by attaching it to another hose as this reduces the cooling effi ciency
of the appliance. If hose needs to be extended, use as few bends as possible.
• Consider elevating the unit in order to keep the hose as straight as possible.
NOBOCOOL NC-49DP/C

ATTENTION
• The exhaust hose should be not longer than 1.5metres.
• Never bend the exhaust hose excessively when the appliance is working.
• Elevate the unit if possible to keep the exhaust hose straight.
• Always keep the exhaust hose at its shortest length and as straight as possible when the appliance is working.
This will ensure maximum cooling output.
• Never move the appliance by pulling the air exhaust hose attached to the back of the appliance.
• Do not move the air conditioner when it is operating.
Correct exhaust hose mounting shown below. If mounting in the wall, the height of the hole should be 17cm~130cm.

WATER DRAINAGE METHODS
WATER DRAINAGE (Fig. 20)
Turn the air conditioner off using the on/off switch on the unit or remote control. Then drain the water tank by
unplugging the drain outlet and allowing the water to flow onto the drain pan. The drain pan will not hold the full
contents of the water tank. A number of fills of the drain pan are required. It may be easier (after 3 or 4 pans have
been drained in order to avoid accidental spillage when shifting the air conditioner) to wheel the unit outside,
remove the drain plug and drain the water onto the ground.
The water tank is considered sufficiently drained when no more water flows from the drain outlet.
Restart the air conditioner by pressing the on/off button. Ensure that the unit is in COOL or DRY mode. The
compressor will start approximately 3 minutes after the unit is switched on.
NOTE: To completely drain all water from the water tank, tilt the unit by lifting it slightly upwards from the front
until no more water drains from the outlet.
This air conditioner is equipped with the very latest MIST technology which means that the water tank does not have
to be emptied. This has been verified by independent testing conducted both in Australia and overseas under extremely
humid conditions. Water drainage will generally only be required at the end of the season (see End of Season Operations
- page 15).
However, the mist technology does not operate when the unit is in dehumidifying (dry mode). Thus, the tank may require
emptying on occasions when operating for long periods in this mode.
As a safety measure, to positively prevent water spillage in dehumidifying mode when the mist motor is not operating,
the air conditioner is equipped with a fail safe device if the water tank fills. The unit will completely stop including both .
fan and compressor. The control panel LED displays “ Ft” as mentioned in the Section on “Self – Diagnosis” – Page 17.
The compressor and fan will not restart until the tank has been drained.
Before draining the water tank (pan) take care not to move the air conditioner as water may spill onto the floor.
