WARNING

 

 

Before any service or cleaning be sure to disconnect the power supply 

                cable from the power supply!

 

 

 

Maintenance  and  service  within  the  warranty  period  may  only  be  performed  by  the 

authorized service person. 
 

 

Please  advise  Kambic  in  before  alternation  &  modification.  It  is  not  allowed  to  change  or 

rebuild any part of the construction without producer's written permit. 
 
All spare parts are in stock in the producer's magazine. It is only allowed to use the original 

spare parts. 
 
Maintenance  and  service  within  the 

warranty  period  may  only  be  done  by  the  producer’s 

service department or authorized service. 

 
With proper care the instrument should require very little maintenance.  Keep the interior 
and the exterior clean. The bath should be cleaned regularly to prevent a buildup of oil or 

dust. For cleaning use some soft cleaning detergents and soft cloth. 
 
Periodically check the fluid level in the bath to ensure that the level has not dropped. A 

drop  in  the  fluid  level  affects  the  stability  and  dramatically  the  uniformity  of  the  bath. 
Changes in fluid level are dependent upon several factors most often it is the volumetric 
expansion of the fluid! 
 

Heat  transfer  medium  lifetime  is  dependent  upon  the  type  of  medium  and  the 
environment.  The  fluid  should  be  checked  at  least  every  month.  Once  some  fluids  have 
become  compromised,  the  break  down  can  occur  rapidly.  Particular  attention  should  be 

paid to the viscosity of the fluid. A significant change in the viscosity can indicate that the 
fluid is contaminated, being used outside of its temperature limits, contains ice particles, 
or is close to a chemical breakdown.

 

 

In the event of failure, call the service;
