Danger of accidents! 

Qualified staff in charge of installation and maintenance have to be trained in accordance with EN 
378-Part 4 and (EC) No.307/2008 and must strictly follow the legal provisions. 
Any works or modifications at the air conditioner which are carried out improperly can lead to mal-
function and so endanger operational reliability. We recommend having all works and modifications 
carried out at an authorized KONVEKTA Service Station .  
Before carrying out any maintenance works at your air conditioning unit, carefully read the  
KONVKETA safety provisions (TD00052A ) in order to avoid any dangers and accidents!

change  the  oil  suction  strainer  has  to  be  cleaned.  Observe  the  oil  quantity  according  to  the  com-
pressor type (see chapter: “Technical data compressor”).

Always keep condenser coil fins clean. Severe soiling cause’s excess pressure within the a/c-unit 
system and it automatically stops working.

case of severe soiling more often.
