Electrical Safety Precautions
5
1. When transporting and moving, the ice machine must not tilt more than 45
degrees.
2. Using independent source of water and checking regularly to prevent low water
pressure, fluctuations or filter clogging.
3.Do not store any sundries in the ice bin. do not freeze any food in the ice bin,
and keep the ice shovel clean.

the ice bin door immediately after taking out the ice.
5.Ice machine should be away from heat source, prohibited exposure in high or low
temperature environment, should try to avoid direct sunlight, so as not to affect the
heat dissipation of the machine
6.It is forbidden to splash water directly on the surface of ice machine otherwise it
may cause short circuit, electric leakage and other faults.
7.If it needs be stopped working for a long time,it should be switched on and run 4
to 6 hours every two months.
1.Do not unplug when your hands are wet.Unplug before any maintenance or
cleaning works.
2.The socket must be securely grounded.
3.The electric control system has a voltage of more than 36V, do not open or touch
it when working. If you need to repair,please contact the manufacturer, or please
handle it by qualified professional and technical personnel.
4.The power connection shall be according to instruction of the nameplate, and the
specified power supply shall be required. Ensure the specification of the wire which
used for connecting shall be determined to meet the requirements. If possible,
please use specific power socket and fuse.
5.The power plug should be unplugged or cut off when the ice macgine stops working.
Place smoothly Be well ventilated Avoid sunshine

Adjust Ice Thickness
Ice thickness Setup:
6
Press the + or - botton for 3 seconds, the digital tube display C1 at the first two
place, the last two start flashing and enter the ice thickness setting state. At this
point, every time you press the + (or -) button, the number displayed on the
digital tube increases(or decreases) by 1, that means the thickness of the ice
increases (or decreases) by 1 minute, the adjustment range is 0~35 minutes. If the
button is not pressed within 10 seconds, the digital tube will stop flashing and enter
the normal operation state. At the same time, the ice thickness data is saved. If the
cleaning button is pressed, the ice thickness data is directly saved and entered into
normal operation mode.

Working procedure

1.Automatic cleaning
Automatic cleaning after power on (Once,2 minutes)
Each time when the ice machine is switched on, it performs a 2-minute automatic
cleaning procedure, to rinse the floaters out of the ice trays and tank. In 2 minutes,
the water tank is continuously filled and the pump is running. Operator can hear the
sound of pumps working, and water flows down to the tank from the top of the ice grid.
Then the water spills out of the tank and flow away from the outlet of ice bin.
2.Ice making(Cycle,up to 40 minutes)
After automatic cleaning, the pump will start up in 45 seconds, then the ice making
begins. While making ice, the pump continues to work. Water flows from the top of the
ice grid down into the tank, and the water slowly cools until it freezes. In the process of
ice making, the thickness of the ice is measured by an ice thickness detector, When the
setting ice thickness is reached, the program moves to the ice-shedding step. If the gap
of ice thickness detector is too large, once the ice making time exceeds 40 minutes, it
will also be forced into the ice-shedding process
3.Ice-shedding(Cyele,up to 40 minutes)
During the Ice-shedding process,the ice grid is heated and the surface of ice at
where sticking to ice grid become melting, because of the gravity of ice itself, it will
fall off and complete a shedding process.
The falling ice blocks will push the baffle to turn over, and the baffle will be reset due
to itself-weight, then the machine started making ice again. However, when there are
too many ice blocks in the ice bin, the ice blocks against the baffle and so that the baffle
cannot be reset, the control chip indicates that the ice is full and the ice machine will
stop temporarily until the baffle is reset.
1.Water pump Directly observe whether there is water flowing from the ice
grid. If there is no water, the pump will be failure.
The steps of an ice machine are divided into there parts:
Fault self-diagnosis
2.Refrigeration After 10 minutes of ice making, the water in the sink becomes
noticeably colder, that you can easily feel the low temperature.
3.Water feeding In the process of automatic cleaning, water can be observed
to flow continuously from the overflow pipe of the water tank into the ice bin. However,
water will normally account for more than half of the water tank.

Maintenance
9
Please carry out the maintenance according to the requirements of this manual,
so as to improve the reliability and service life of the ice machine. And avoid increasing
the energy consumption coefficient of ice production while maintaining sanitation.
1.Clean the area around the ice machine regularly, to keep the blinds of the ice
machine which are used for ventilation from clogging.
2.Clean the shell with a neutral cleanser, then wipe it clean with a soft cloth. If
necessary, commercial stainless steel cleaner and polishing agent can be used.
3.Filter element should be checked regularly. Most of the filter element within 6 months
should be replaced, or according to the instructions on time replacement.
4.The water tank and ice bin can be cleaned with water pipes, but do not have
excessive water pressure. Do not directly flush the water pump and upper part of ice
grid, to prevent the circuit flooding.
5.Condenser of air cooled Ice machine:Clean the condenser every three months. Use
a soft brush or a vacuum cleaner with a brush to scrub the condenser’s fins from up
to down along the fin direction to avoid damaging the fin and affecting the cooling
effect.
The instruction manual is an integral part of the product, please keep it properly.
Any maintenance of the ice
machine is not covered by the
manufacturer’s warranty.
The filter element should be
replaced regularly.
The edge of wind condenser fin
is sharp, please be careful
when cleaning.
Before cleaning and
maintenance, make sure to turn
off the water and power
sources and pull the plug.
Please pay attention to cleaning
the scale inside the ice maker
to ensure that the waterway is
not blocked.
