  Hazards Related to the Instrument 

Please pay attention to the following safety tips: 

Danger

 

 

Do  not  use  it  in  explosive  gas  atmospheres  or  explosive  dust

environment.

 

Prohibit 

 

Do not use it outdoor. Get wet in the rain or splashing water will

cause electrification on metallic shell surfaces, and will cause 

casualties. 

Warning

 

 

Make  sure  that  the  power  supply  is  in  conformity  with  the

requirements on the nameplate. 

 

Please  place  the  equipment  equipotential  connection  and  earthed

reliably. 

 

Before open the equipment enclosure for maintenance and repair, be

sure to disconnect the power supply, then operate it after 5s, ensure 

the residual voltage release to safety value to avoid electric shock. 

 

Do not use it before install the shell to avoid electric shock.

 

If  found  refrigerant  leak,  please  take  ventilation  measures  to  reduce

refrigerant content in the air as soon as possible. 

 

The recycling material should has no corrosive on SUS304.

Note

 

 

Please disconnect the power supply and then troubleshooting if there

is any abnormal circumstances when using it, or contact Professional 

maintenance personnel ccordingly. 

 

Please  wear  labor  insurance  gloves  when  cleaning,  maintenance  and

repair the instrument. Beware of condenser fin injury. 

Note 

Note 

 

Do not close to rotary parts to avoid personnel injury.

Reminder

 

Reminder 

 

Do not use it under high temperature and moist ambient. Otherwise it

will affect its normal running and life span. 

 

Clean the condenser regularly. The cooling capacity of the equipment

will be reduced and its power consumption will be increased when 

the condenser is clogged with dirt. 

 

Keep well ventilation near the inlet/outlet of the instrument. Do not
