2.11 Test Run
WARNING
The Ice machine is factory-adjusted. In general, no additional setting is required after installing the
product. In cases of random modification, it may cause adverse influence on safety, function,
component lifespan, and warranty period.
1. Open shut-off valve of water-supply line.
2. Turn on the ice machine by pushing “POWER” button and operate it for 10 minutes.
3. Turn off the power and remove the front panel.
4. Drain the remaining water inside of the tank after removing Ice cover and disconnecting the ‘ㄷ’ shape hose
that connects the Water tank and Pump motor.
5. After drainage, reattach hose.
6. With a neutral detergent, clean the inside of the ice storage bin.
7. Re-assemble ice cover and the front panel.
8. Turn on the ice machine again.
9. Check if the bin switch works by pushing flap of the bin switch within first 5 minutes of freezing cycle.
10. Continue Pressing flap of the bin switch for 10 seconds.
11 . The ice machine will stop operation with ‘Full’ display. After 5 seconds you should stop pressing the flap of
the bin switch, ‘Full’ will be disappeared and the ice machine goes into the water supply procedure. (The ice
machine will stop operation immediately if you press flap for 10 seconds within 5 minutes after initiating
ice making cycle. If not, the ice machine will stop after completion of ice making and harvest cycle.)

3.4 Operation Cycle
Ice machine is operated in accordance to the following process
(1) Water supplying cycle
Once power is on, wate supply valve opens to fill the water tank with water.
2) Harvesting Cycle
To remove ice made on the evaporator, water flow stops and it becomes hot. Then, ice is
released from the evaporator to the storage container. Once temperature sensor detects a certain
temperature, freezing cycle begins. Water continues to be supplied during the harvesting Cycle.
3) Freezing Cycle
This is the process of making freezing ice. Water is supplied to the surface of evaporator and it
becomes cold. As water keeps circulating, more and more ice is layered. This process is repeated
until water level sensor reaches low. Once it reaches low level, the harvest cycle starts.
4) Drainage Cycle
Residue or impurities will occur in the water tank during the repeating process of freezing and
harvesting cycles. Using the ice machine for a long time without draining may cause damage. After
a certain number of cycles, completely drain leftover water in the water tank by using water pump.
3.5 Safety
1) Maximum freezing time - 60min
To protect the ice machine, maximum freezing time is set to 60 minutes. When freezing cycle goes
over 60 minutes, it switches to the harvesting cycle. During the second freezing cycle, if time goes
over 60 minutes, machine stops and shows error code (E1) on the control panel with a beep sound.
2) Maximum harvesting time - 25min
The maximum harvesting time is 25 minutes. If time goes over 25 minutes, it automatically switches
into the freezing cycle. During the second harvesting cycle, if time goes over 25 minutes, error code
(E2) is shown on the contro panel with a beep sound.
3) High Temperature safety
If temperature outside the evaporator during freezing cycles goes over 140°F (60°C), machine stops
to protect the cycle and error code (E3) is shown on the control panel.
4) Low Water Safety
For protection of water pump, if water level is low after harvesting cycle, machine halts and error
code (E5) is shown on the control panel.

4.2. Interior Cleaning / Sanitizing Procedure
The ice machine should be cleaned and sanitized every six months.Depending on the water
quality of the installation location, it may be more frequent.
WARNING
- Use a detergent and sanitizer for ice machine, and follow the directions of those
products.
- During cleaning and sanitizing, please wear rubber gloves and protective eye glasses
to protect eyes and skin.
