Any time, you can start chiller again more than three minutes later after 
the chiller’s power off, otherwise the chiller can be easily damaged. 

 

 

Prevent wiring from being sprinkled, otherwise conducing creepage and 
damaging the chiller. 

 

 

Do not touch inside, prevent high speed fan and high temperature from 
hurting body. 

 

 

Pay attention to the water line of tank at any moment. (Under the state 
of full water in all pipes)

 

 

3.4.3 Requirements of cutting accessorial air 

Air pressure: 0.02~0.4Mpa. 
When  using  air,  must  insure  the  biggest  grain 

5

μ

m  ,the  maximum 

condensate  content 

5mg/m

,  the  maximum  oiliness  content 

0.1mg/m

for these we should equip oil-water separator, drier and filter.
