About Intelligent Power-Off Protection
For highest efficiency of air filtration !
Do Not place the unit in the following places or areas.
■
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.

■
·Direct sunlight, nearair-conditioning unit airflow orheat.
(This may cause distortion, colour change or reduced life.)
·Near television, radio etc.
(This may cause television image disorder and radio noise.)
→Keep the unit1morabove away from such devices.
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 will possibly be diminished.
Do Not use the same power socket as one already
used for television or radio.
Do Not place objects on the unit.
(Television image disorder and radio noise may appear
when power plug is inserted into socket.)
→Please use alternative power sockets.
(This might affect the operation of the unit.)
■
Do Not obstruct air inlet or outlet.
(This could reduce efficiency of air filtration by unit.)
NCCO Technology
Basic Information
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 under the control of its intelligent control of an automatic power-off and re-start
function after 30 minutes of rest (See 'About Intelligent Power-Off Protection' for further info).
Long Life - Take example of adsorption capacity of activated carbon, which has a lifetime of only about three months,
compares 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 with all extinguished indicators after continuous use over a period of 8 hours and then will
restart automatically after 30 minutes downtime. During downtime, user might restart unit by pressing ON / OFF Button.
Our Intelligent power-off system is able to effectively avoid excessive load and eliminate any risk during the supply of power.

Q6
When the NCCO Reactor has operated for 11,000 hours,'nC' displays at Display
Screen as a reminding to check the operation situation of NCCO Reactor.
A
When 'nC' displays at Display Screen, under Power-Off state but without disconnecting
power supply, long press the ON / OFF Button for 10 seconds, where a 'Da' sound should be
heard from the unit. Then, press the Air Speed Increase Button. 'nF' will display at the Display
Screen for 3 seconds to exit reminding mode. Next, turn on the unit for normal operation.
Q1 A'Di·Di·Di·Di' sound is heard from the unit and the unit is not operational.
APlease re-check whether the HEPA Filter and NCCO Reactor
Combinationhas been properly installed and all packing removed.
If not, please re-install HEPA Filter and NCCO Combination.
Q2 Can the HEPA Filter be washed?
ANO, the HEPA Filter is made of composite material and washing will seriously affect
its purification capacity.

AWhen 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 The unit emits an unusual smell or smoke (e.g. smoke, flames or burning).
AImmediately turn off unit and disconnect power supply. Then contact your local
service centre or authorised distributor service centre for resolution.
Q5 When the HEPA Filter has operated for 3,000 hours,'HP' displays atDisplay Screen as
a reminding to check whether HEPA Filter needs to be replaced.
A
When 'HP' displays at Display Screen, under Power-Off state but without disconnecting
power supply, long press the ON / OFF Button for 10 seconds, where a 'Da' sound should be
heard from the unit. Then, press the Air Speed Reduce Button. 'HF' will display at the Display
