1. While maneuvering, do not tilt the unit more than 40°.
Too much tilting might cause malfunction of the machine.
Do not put too much vibration or shock to prevent the gas leakage.
To maneuver with forklift or hoist, please refer the below picture.
2. While using forklift
- Make sure the machine is balanced well.
- Make sure the fork is inserted deep enough to hold
the machine stably.
3. While using hoist

1. Do not use the machine at where explosive, flammable gas leakage
might happen.
2. Install the machine at where is well ventilated and has low humidity.
3. Do not place any external substance near the ventilation port.
4. Make sure the air inlet & outlet port have enough space to suck
in & pull out the air.
5. Do not install the machine at powdery, dusty, oily area.
(Do not place any external substance within 500mm from the
ventilation port)

1. Make sure the pressure of the inlet valve lower than 0.1 Mpa,
outlet valve lower than 0.6 Mpa.
2. Check if there is no leakage on the pipe while running.
3. Check the loose of the valve connection, leakage, infiltration of air
while running.
4. While installing the pipe, avoid maneuver the valve to
prevent loosing the pressure.
5. Let the supply valve always open, as the machine is designed for
auto-water supply system.
6. Make sure to connect the right valve of inlet & outlet port.
7. When the inner contamination is found for long-time using,
drain out the water and refill it.
8. When not using for a long time, drain out the remaining water inside
the machine using drainage valve and place the machine avoiding
hot and humid place.

1. Before initial start, fill up the tank with clean water (distilled water).
(subterranean water might cause blocking of the pipe and multiple
malfunction)
2. Recommended water is distilled water and tap water.
- Mixing ratio (prevent freezing until -2℃)
distilled water : 90wt%, Antifreeze : 10~20wt%
(If the ratio is not correct, the circulation pump might have leakage.)
3. For the initial running, connect the valve and open it.
The water will be supplied automatically.
Check the water level gauge and run the machine.
4. Refer the picture below to check and supply the water.
Supply the water to reach this level
and start the machine.

6. Make sure the air not to go into the water pipe.
7. The compressor protective system will delay of the initial
start of the compressor.
8. Do not put in fingers or tools through the ventilation port.
9. Do not put any kind of substance that has a chance to drop into the unit.
10. Do not place any kind of external substance near the ventilation port.
11. Make sure to not have your face near the air outlet to avoid any
burnt from the heat.

Maintenance
8
Use the air gun or brush to clean the fin of the condenser.
Make sure not to bend or damage the fin.
Furthermore, do not use iron brush, it might damage the fin.
1. Make sure to manage the water to be clean.
2. Clean the water inlet & outlet valve once every 6 moths, to prevent
any sludge block the pipe.
If the pipe or valve is blocked, it will make a loud noise and worsen
the performance.
4. During the cold season, it is recommended to use anti freeze like
ethylene glycol to prevent freezing to burst.
1. Make sure to cut off the power.
2. Put the cover on the machine to prevent any external substance to
infiltrate into the unit.
3. Make sure to manage the condensers not to have dust or
oil mist on the surface.
4. Make sure to drain out all the water remaining inside the machine.
1. For the maintenance, cut off the power to the machine in advance.
2. Never do the maintenance while the machine is running.
This cause various accident.
