   TIPS:When first time using the machine, if there remains liquid residue in the cylinder.It’normal liquid residue caused by ex-factory cleaning and won’t affect machine performance and its service time.If this causes any inconvenience, we feel sorry for that and thank you for your understanding.

B. Installation

1. SELECTING LOCATION
   a. Place the machine on a level counter that is stable and strong enough to safely support its weight.
   b. Place the machine in a location that allows adequate space at the back and each side for proper ventilation. Keep 50cm space from all sides of ventilation. The machine should shade from the sun and should not be located too close to the units that radiate excessive heat.
   2) POWER SUPPLY
   a. Select the proper power supply according to the voltage and power on the nameplate.
   b. Connect the power wire and the power supply, ensuring the yellow and green wire was connected with the ground wire firmly.

Caution: a. For safety, ensure the ground connection is in good condition.
b. All the exterior wires and other appliances must confirm with national standard.

C. Testing Running

1. Switch “ON” the power switch and you will hear “Beep”,all the graphic patterns on the screen will be lighted up and then the graphic patterns will extinguish,machine enters “Standby” mode.
2. Press “Wash”, the corresponding indicator will be lighted up and at the same time you will hear the sound of beater system working.Press the “Wash” button again,beater system will stop.

D. Clearing & Sterilizing
Step 1: Prepare 5-6 liters of warm water, mix with food detergent according to manufacture’s specifications. And this is the sterilizing solution.
Step 2: Pour the solution into the hopper While the solution is flowing into the freezing cylinder, brush and clean the mix hopper.
Step 3: Press the key of “clean”, and let the machine running for about 5 minutes.
Step 4: Place an empty pail beneath the draw spout and push down the draw handle. Draw off all solution.
Step 5: Repeat this operation for 2-3 times with water only.

b. Draw off all the water in the hopper after clearing, or else it will damage the beater while the compressor is running.
c. While press the key of “clean”, pay attention to the indicator light in order to avoid pressing the wrong key.

Operation Instruction

A. Key Instruction

1. display screen
2. adjust key（up）
3. adjust key（down）
4. set key
5. standby key
6. Wash key
7. Auto key

SET KEY(UP / DOWN)
a. set hardness level：
When the machine is ready mode, press “UP” or “DOWN” key for more than 2 seconds then the “SET” word on the displayer flashes and the number shows the setted level of hardness. For example, if the displayer shows “02” it means the current setting level is 2. The stiffness will increase one level each time that the “UP” or “DOWN” key is pushed. It circulate from “01” to “10” ( 01(soft)-02(hard)-03(harder)——-10(hardest)-01(soft))
b. set parameters：
Machine in “standby”mode, press “UP” and “DOWN” at the same time and hold for 5 seconds,the “SET” window displays “P1” icon(Periodic Restarting Time Seeting), Press” ”,

the window will display “05”(The variable range is from “5~15” minutes, press”UP” and “DOW” can change the setting volume)
Continue pressing “ ” key for two times, every time operation can change the icon display on the window. And when each icon appears,by pressing “ ”key for one time to change the setting you want.(Volume can be changed by pressing “UP” and “DOWN”)

Press “ ” , the machine will enter circulatory volume setting. Without any operation in ten seconds, setting volumes will be automatically saved and back to the standby mode.
Time Setting
In standby mode, press the “AUTO” and “WASH” buttons for 5 seconds, the window shows “F1 01”, then you can click the “UP” or “DOWN” key to adjust the back number.
Press “ ” key, the window shows “F2 12”, by such analogy until ” F7 30″.
Note: F1 says mark symbol, 01、02、03……30says actual value.
F1 — week (00 – Sunday) F2 — year F3 – month F4 — date
F5 — hours F6 — minutes F7 — seconds

WASH KEY
Press wash key “ ”, the “CLEAR” icon light and the beater starts to work. It will be closed when you press it again.
STANDBY KEY
Press standby key ，“STANDBY”and“FRESH”icon will light. The little compressor for hopper is controlled by setting temperature. It will stop when the temperature is less than the setting value, and it will start again if the tempreature in hopper raise for 2℃. When the temperature in cylinder is less than the setting value, the big compressor stops, after 15 seconds the beater motor stops. When the tempreature in cylinder raise for 2℃, the beater motor start, after 3 seconds the big compressor starts. The temperature of hopper and freezing cylinder can be directly displayed on the screen.
 AUTO KEY
Press standby key，“AUTO”and“FRESH”icon will light. The little compressor for hopper is controlled by setting temperature. It will stop when the temperature is less than the setting value, and it will start again if the tempreature in hopper raise for 2℃. The big compressor for cylinder will stops when the hardness value reach 99，after 15 seconds the beater motor stops.
The beater motor will starts again when the time goes for setting value(cycle time to restart for machine). After 3 seconds the big compressor starts.
PROTECTION FUNCTION 

• The sensor for freezing cylinder is open circuit or short cirult, hardness window on the screen will show“RL”or“RH”, the buzzer will screams and the machine stop.
• The sensor for mix hopper is open circuit or short cirult, hardness window on the screen shows “RL”or“RH”, the buzzer screams, and the machine stop.
• When the machine is in “WASH” or “AUTO” mode, if the digital displayer shows “— —” with alarm and machine stopping，and keys on the operation panel will be locked. That means the proximity switch is damaged or not in correct position. Change it or put it in the correct positoin.
• When the digital display shows “NL” with alarm and machine stopping, means the belt of beater motor system is skidded.
• If pushing the handle for more than 1 minute，hardness window on the screen will show“Cb”， the buzzer will screams and the machine stop.
• Under “AUTO” or “STANDBY” status，if mix lack，hardness window on the screen will show “CL”and hardness alternately，the buzzer will screams for 20 seconds。
• The number “01” will flash if just 1 day left for the setting cleaning cycle. When the cleaning cycle is over, the window will shows “OVER”, and the buzzer works intermittently. Then you just can use “WASH” and “PUMP” functions. The refrigeration function is locked, and only can be unlocked after switch power off and on again. The cleaning cycle will count anew.
• Less cooling,no cooling, or cooling over one hour still ice cream not forming, the screen will display”ERR”, and sound of “BEEP” will continue.

16. New design middle piston

d. Put the components into disinfecting solution to clean,check the beater, gasket for beater, O-ring for dispenser door, supporting sleeve and O-ring for piston, if they are worn oldly, they should be replaced;
e. After cleaning, lubricate the parts with vaseline, then install the parts according to the method of taking apart.

Notice : Before installing the piston, O-ring for piston, beater and gasket for beater, you should lubricate vaseline (lubricating vaseline onto the groove of the gasket, do not onto the beater’s end ), using the vaseline frequently can extend the service life of
components.
B. Cleaning Machine Cabinet
Keep the machine cabinet clean, use wet towel to clean the cabinet, and do not flush the machine with water directly.
C. Cleaning Condenser
After be used over a period of time, the condenser maybe thick with dust, and this will effect radiate heat and cause refrigeration difference, so it needs periodic cleaning (every half year)
Cleaning methods:
Step 1: Disconnected the main power switch.
Step 2: Remove the back panel and side panels.
Step 3: Clean dust with tools such as vacuum cleaner, high-pressure air and hairbrush, be careful while cleaning to avoid damaging the fins of the condenser.
D. Belt Adjustment
After be used over a period of time, the belt of the machine maybe elongated, so it needs to be adjusted. Disconnected the main power of the machine, remove the back panel and side panels, adjust the tension bolt and make sure the belt is in appropriate tension.
