After entering right password in the setting menu, long press MODE to enter testing menu, press UP and DOWN to 

choose subitem (testing, cycle, defrosting, back flush, top tank UV, water outlet UV, bottom tank UV) , press C/F    to 

perform ,then press C/F again to quit, long press MODE to retreat from testing menu. 

After entering any menu among reset, other menus will automatically reset.   

 

3. Operation Instructions: 

 

3.1 Before the first running of the machine, if connection to city water is required, connect 3/8 pipe to the city water 

inlet. After the installation is done, clean and sanitize the filtration system as per instructions in Annex I.   

3.2  Start  working:  After  the  main  power  supply  is  put  in,  turn  the  stop  button  clockwise:  after  the  master  power 

supply  is  switched  on,  turn  the  E-STOP  button  clockwise  and  the  red  power  lamp  will  be  lit  on,  Automatic 

electrification heating the oil heater of compressor, after electrifying for more than 1 hr ( 

For the first time start, 

or long blackouts do not work and reuse

make sure the oil heater is electrified more than 1h 

), Press START 

button,  green  RUN  and  red  POWER  lamps  will  be  lit  on.  Compressor  and  fan  motor  will  start  running  after  8 

minutes, and solenoid valve will open in main circuit of compressor.

 

After starting up, check if the compressor ampere value is normal; If the current of each phase stable, and if the 

display value of high- and low-pressure gauge is normal (Low pressure display value: 0.3~0.

7

MPa, High pressure 

display value:1.

2

~2.5MPa), the pointer of high- and low-pressure gauge should not oscillate sharply. If found fault 

switch  trip  or  malfunction  in  controlling  loop,  switch  off  the  system  immediately  and  fix  the  breakdown.  The 

interval should not be less than 8 minutes and start up cannot exceed 6 times one hour, otherwise the compressor 

would suffer damage. 

 

3.3 Press STOP button to switch off the machine. RUN indicator will be off. When the machine is to be turned off in 

emergency, press E-STOP button. Turn E-STOP button clockwise to recover power supply.   

3.4 When display screen WARNNING icon is flashing it means unit failure. It could be phase sequence error, high or 

low  voltage  protection  action,  overload  hint  of  thermal  relay.  Please  follow  the  display  screen  to  troubleshoot, 

after troubleshooting is needed for unit, turn off the power supply, restart the unit then be working normally 

3.5 For the first operation of the machine, it should take 24 hours waiting for water output, When the water level of 

the top tank is higher than the lower limit

Press the outlet pump valve action, and press the outlet pump valve 

again  to stop  it  working.  When the water  level of the top tank is below the lower  limit for 1 minute, the outlet 

pump valve stops automatically. When the water level of the top tank is lower than the lower limit, keep pressing 

the outlet pump valve, when open, the outlet pump valve stops. 

 

 

 

Ⅵ. Precautions

 

1.The machine must be kept standing during the packing or transport. If inclination is required, the allowed angle from     

    the floor must be more than 45 degrees. 

2.For the first time start, or long blackouts do not work and reuse

make sure the oil heater is electrified more than 1h 

3.Avoid long-time exposure to sunlight

 

4.Avoid long-time direct eye exposure to Ultraviolet device as it may hurt the eyes 

5.The machine is not suitable for use in places with spray water, do not use spray water to clean the machine. 

6.To prevent the machine from damage caused by freezing, please drain off the remaining water and stop operating the 

machine if the environment temperature during its working is below 00C.
