For long-term storage
1. Drain raw ice cream liquid, clean the machine, and assemble the dasher cover and dasher
assay while the body is still wet from cleaning.
2. Lock the water supply valve. The power supply must be connected at this point, so check if it is.
3. Disconnect the water supply valve from the side of
the machine to drain any remaining water in
the line. (Figure 1)
4. Unscrew the quick valve cover from the lower part
of the left panel and have a basket ready at the
outlet hose.
5. Turn and open the quick valve inside of the valve
cover counter-clockwise.
This will allow the water to flow from the outlet hose.
(Figure 2)
6. Press the "AUTO" button and keep the machine
running for 5~10 minutes.
7. Press the "STOP" button on the front to stop the machine.
8. After water is completely drained, lock the water valve (Figure 1)
and quick valve (Figure 2) and close the cover.
(About 1.3~1.5 liters of water will be drained.)
9. To reuse the machine, lock the quick valve again (Figure 2) and reconnect the water
supply line (Figure 2)
(Up to 10 minutes until the high-pressure switch is activated and
the machine stops.)
(The basket is for collecting the water that may spill
on the ground.)
(Refer to the user instruction for the cleaning method.)
Waring
●
The machine will be out of order if water gets frozen due to sub-zero temperature in winter.
Be sure to drain water before storing the machine.
● The manufacturer will not be responsible for the freezing and bursting of the machine without
draining water. Be sure to keep the following precautions to avoid charging of excessive
repair cost:
● Be sure to check the following when connecting the water supply line!
1. The pipe must have a diameter bigger than Φ12.7mm.
2. Check if the pressure is between 0.3 and 0.5 Mpa on the water pressure gauge after
connecting the line. (The water pressure gauge is on the back of the machine.)
3. If pressure is lower than 0.3 Mpa when operating the machine, control the flow of
the main valve to ensure stable operation.
4. The high-pressure cut-out switch (HPS) of the machine will be activated to stop and
protect the machine unless pressure is strong enough.
Remember to maintain the proper water pressure.
