and save these instructions before using.
For your safety, the information in this manual must be followed
to minimize the risk of property damage or personal injury.
WARNING
Electricity Safety
Only connect the power cord to the voltage
rating that matches it on the rating plate to
avoid danger such as electric shock or fire.
And be sure the electric outlet is in an
inside location to protect from moisture.
Be sure the power cord does not to be
bend by force and do not put a heavy
object on it to avoid any electric leakage
or damage.
●
●
Do not pull the power plug from the outlet
with a wet hand or get the plug wet to
avoid electric shock.
●

03
04
Never splash the water filtration system
with water to avoid the risk of electric
shock.
●
Keep the cord out of heavy traffic areas.
To avoid fire hazard, NEVER put the
power cord under rugs, near heat
resisters, radiator, stoves, or heaters.
●
Do not use a damaged power cord or plug
, and loose consent where the plug cannot
be inserted securely to avoid fire or shock
hazard. If the power cord is damaged, it
must be replaced by the manufacturer, its
service agent or a similarly qualified person
in order to avoid a hazard.
●
Unplug the power cord when not using
for an extended period of time. Insulation
may deteriorate, causing short circuit, fire
and/or electric shock as a result.
●

How does Our Product Filter Out Wastes?
The reverse osmosis membrane system has been applied to our water filtration
system, where a TFC membrane with pores of 0.0001
㎛ (1/1,000,000 of hair) is used.
The components of our water filtration system are as follows;
FILTRATION SYSTEM
This reverse osmosis system contains a replaceable treatment component,
critical for the effective reduction of total dissolved solids and that product
water shall be tested periodically to verify that they system is performing
properly. Replacement of the reverse osmosis component should be with
one of identical specifications, as defined by the manufacturer, to assure the
same efficiency and contaminant reduction performance.
Note
Using a step-by-step filtration method per pore, this filter effectively
reduces various foreign bodies that come from the supplying water
pipe such as bits of rust and also protects the membrane. The
Plus-Sediment filter vastly reduces dirt, sand, rust particles, and
other sediments.
Plus-Sediment Filter
The activated carbon filter reduces chlorine, odor, tri-halo methane,
gas additive MTBE, and organic pollutants such as pesticides,
EDB, benzene, and TCE.
Pre-Carbon Filter
The RO(Reverse Osmosis) Membrane filter reduces cryptosporidium,
viruses, coliform, bacteria, radioactive radon, arsenic, copper, iron,
lead, manganese, as well as dissolved chemical solids such as
bicarbonate, cyanide, ferrocyanide, nitrates, and nitrites. (CHP-
04AR/L)
The Post-Carbon filter reduces unpleasant smell from water and
enhances water flavor. (CHP-04AU)
RO Membrane Filter / Post-Carbon Filter
The Fine Post-Carbon filter reduces unpleasant smell from water
and enhances water flavor, and prevents carbon particles to flow
into storage. (CHP-04AR/L)
Neo filter reduces the foreign materials and waterborne
microorgarnisms. (CHP-04AU)
Fine Post-Carbon Filter / Neo Filter
UV lamp circulates the treated water inside the reservoir tank so
that it prevents secondary contamination inside it.
