Preparation
●If not, it may cause fire,
electric shock or the
machine malfunction
X
●There is a risk of fire or electric
shock. It may also cause the
product malfunction
No thinner,
organic agent,
petrol or gas
●
It may cause bad quality or odor of the water for ice making
●If water in cooling water coil and pressure valve is
frozen, there may be freezing-burst
●
If not, please remove water in cooling coil and then store it
●
In case of out of temperature
degrees, it may cause damages
or malfunctions
●
Depending on temperature or
humidity, amount of ice making
can be different
●
If water pressure is higher than
6 bar, please install pressure
decrease device
●
When it is less than recommended
pressure, please install pressure
pump. Please contact to the service
center(pressure pump is an option.)
Less than 6bar
●Please keep balance
between front and back
and right and left within
2mm. (It may cause
uneven ice quality)
●If drainage is not well done,
water will overflow or standing
water may cause unhealthy use

●After connecting drainage hose to drainage pipe
for storage house, please fix it firmly.
- Please install drainage hose in tilt for better flow
- In case of the location far from sinkhole, please use
extending hose(inner diameter :ø19), preventing
leakage from the connection
●Please install open/close valve and connection
nipple(PT 3/8”) and connect In(supply) and
Out(drainage) connections on the back of the
product, respectively, using PE tube hose(ø9.52)
●Please avoid PE tube hose from snapping or folding
●Please ground grounding line in the bottom of the
back of the product properly according to electric
safety regulation
●Water supply or gas supply pipe is very dangerous.
Please do not connect them
Out(Drainage)
In(Water supply)
- Please use power plug with AC 220V 50Hz/ 60Hz wall socket
- Please use wall socket with higher than 15A
- In order to prevent severe electric shock and damages to the machine,
please install proper grounding line defined in electric safety regulation

Operation
① After pulling up lever pin, make a little crack
② Insert middle part of the hose out of bracket
③ In order to avoid hose twisted, roll it into roller and attach it at groove on lever and
insert lever pin into hole and fix hose on bracket
④ Insert pipe into the end of water supply hose falling down and put it naturally into material
tank(Not making water supply hose folding or twisted, make its end attached
to the floor of material container)
① Insert material container to upper part groove
② By inserting stainless pipe into the end of material supply, put it naturally into ice making
water tank(Not making ice making material supply hose folding or twisted, make the end of the
hose attached to the floor of the material container)
