   PRECAUTIONS FOR SAFE OPERATION 

 
 
 
 
 

Never install the unit in a location where corrosive materials such as sulphur compounds are 
likely to be generated (e.g. near a drainage facility).

    Corrosion of the copper pipes may result in 

the deterioration and consequently the failure of the cooling unit. 
 

This unit must be plugged into a dedicated circuit protected by a branch circuit-breaker. 

 

Use a dedicated power source as indicated on the rating label attached to the unit.

    A 

multiple-tap source may cause fire due to excessive heating. 
 

Do not climb on top of the unit or put any objects on the unit.

    Falling from the unit may cause 

injury; falling objects may cause damage to the unit 
 

Never store corrosive substances such as acids or alkalis in this unit except in a sealed 
container.

    These may be harmful to your health and may cause corrosion of internal components or 

electrical parts. 
 

Check the settings when restarting operation after a power failure or after turning the power off.

   

The settings may have changed as a result of stopping the unit.    Stored items inside the unit may be 
adversely affected when operation is resumed if the settings have changed. 
 

To ensure the safety of the service engineer, submit a safety check sheet with the required 
items filled out.

  This is provided as the photocopiable “Safety Check Sheet” at the end of these 

operating instructions 

 

 

CAUTION
