Setting & Operation Requirement
Information & Setup
Matters That Need Attention
For highest efficiency of air filtration!
■ Do not place the unit in the following places
or areas.
Lithium Battery Safety Instructions
Following Aspects Need Attention:
■Removing indoor dust
.
Place unit on a flat surface in an open area where dust falls easy.
■Best air circulation location area.
Place unit at least 15cm (6”) from a wall, furniture, curtains etc, otherwise its filtration efficiency
could be diminished.
• Direct sunlight, near air-conditioning unit air flow or heat.
(This may cause distortion, colour change or reduced life.)
• Near television, radio etc.
(This may cause television image disorder and radio noise.)
→ Place unit at least 1m from such objects.
■ When operating unitin same location for a long
period of time.
• Surrounding walls or floor could become dirty.
• When maintaining unit, please change the location.
■ Do notuse the same power socket as one already
used for television or radio.
(Television image disorder and radio noise may appear when
power plug is inserted into socket.)
→ Please use alternative power sockets.
■ Do not place objects on the unit.
(This might affect the operation of the unit.)
(This could reduce efficiency of air filtration by unit.)
■ Do not obstruct air inlet or outlet.
If one observes an undesirable odour from the installed battery, or from other areas within the unit
on first-time operation, please do not operate and return to the distributor.
Keep the unit away from an environment involving a heat source, a high barometric pressure or an
increasing pressure on the surface of unit during its operation. Place the unit in a secure and safe
operating location and away from children.
Avoid the unit being shaken in a serious vibrating environment.
Avoid storing or operating the unit in a strong sunlit and hot environment. This will prevent the battery
from overheating, becoming distorted, smoking or shortening its life.
Avoid operating the unit in an environment which might conduct static electricity and induce the battery
to overheat, distort, generate smoke or shorten its life.
Only charge the battery with the dedicated charger and follow the recommended charging method.
Insert battery in correct polarities. Do Not arbitrarily disassemble or refit unit and battery. For safety
concern, do not place unit at a wet location.
Keep the battery at half-charged condition without any damage and place in the unit a cool dry location
when stored for a long period of time.
Do not put unit into fire or water.

About Intelligent Power-Off Protection
Patented NCCO Air Purification Technology Brings You Fresh and Clean Air
NCCO Air Purification Technology has world-wide patents.
The principle of NCCO technology is based on the efficient adsorption of pollutants through the use of active
oxygen to break the chemical bonds of the pollutant molecule and then decomposing them to Carbon Dioxide
and water molecules.
Characteristics of the technology are extremely long filter / Reactor life, no secondary pollution, sterilisesand
removes carcinogenic pollutants such as formaldehyde and effectively deodorises.
NCCO IS AN INNOVATIVE TECHNOLOGY INVENTED BY MEMBER OF HKUST
ENTREPRENEURSHIP PROGRAM.
About NCCO (Nano Confined Catalytic Oxidation) Air Purification Technology
■

■
NCCO Technology
Our patented NCCO (Nano Confined Catalytic Oxidation) technology used inside our
GojiAir NCCO Air Treatment Unit is able to effectively remove fine particulates, passive
smoke, pollen, PM
0.15 , bacteria, viruses and more.
It brings you clean fresh air indoors when the outside air environment is polluted. The unit
has safe operation of up to 8 hours (battery powererd under the control of its intelligent
control of an automatic power-off and re-start function after 30 minutes of rest (See bottom
of page for further info).
Long Life - Take example of adsorption capacity of activated carbon, which has a lifetime of only about three
months, compared with NCCO product which will last upto 12 years.
No Secondary Pollution - For other types of filters, they will be saturated relatively quickly and thus release
unabsorbed pollutants back into the air and is called secondary pollution. NCCO technology continuously
decomposes pollutants into harmless Carbon Dioxide and water.
Sterilisation and Formaldehyde Removal - NCCO technology can effectively decompose chemical pollutants
including formaldehyde which is deemed to be carcinogenic. It also filters suspended particles, heavy metal
particles, pollen, viruses and bacteria.
EfficientDeodorisation - NCCO technology can completely remove unpleasant odours.
GojiAir NCCO Air Treatment Unit is designed using an Intelligent Power-Off Protection System.
The unit will intelligently power off after continuous use over a period of 8 hours and then will restart
automatically after 30 minutes downtime once connected to an external power supply.The unit will use the
intelligent system to power-off after continuous use of 2 hours, and then will restart automatically after
10 minutes of downtime when using its internal (battery) power supply.Our intelligent power-off system is
able to effectively avoid excessive load and eliminate any risk during the supply of power.

Remove Air Inlet Cover before washing it with water (only Air Inlet
Cover can be washed with water). the air inlet is the prefilter. The
main body of the unit can be wiped with a soft dry cloth but avoid dust
falling on HEPA Filter or NCCO Reactor.
After washing the air inlet cover, please ensure that it is completely
dry before replacing onto the main unit.
Tips : A damp (non-abrasive) cloth can be used to clean the unit
surface.

Can the HEPA Filter be washed?
NO, the HEPA Filter is made of composite material and washing will
seriously affect its purification capacity.
Q3
A
Air quality still has not improved even after operating for a long period
of time.
When the unit being used in a seriously polluted area, the treatment
process will take a long time. Continue operating the unit in high airflow
mode until pollution is reduced.
Q4
A
The unit emits an unusual smell or smoke (e.g. smoke, flames or burning)
Immediately turn off unit and disconnect power supply. Then contact your
local service centre or authorised distributor service centre for resolution.
Q1
APlease re-check whether the HEPA Filter and NCCO Reactor Combination
has been properly installed and all packing removed. If not, please re-install
HEPA Filter and NCCO Combination.
A ‘DiDiDi’ sound is heard from the unit and the unit is not operational.
