This chapter contains information necessary to maintain and/or 
troubleshoot the EST Analytical Encon Evolution. 
 

The purpose of this Chapter is to familiarize the user with the various integrated maintenance 
and troubleshooting functions of the Encon Evolution.   
 
The Encon Evolution will require minimal maintenance of consumable items such as, tubing, 
traps, septa, Teflon ferrules, power cord, etc.  The interval at which maintenance is required 
depends on use and sample types.   
 
In order to maintain the safety integrity provided by the instrument for parts containing liquids, 
during maintenance, ONLY use replacement parts provided by EST Analytical. 
 

  

CAUTION:  Before Maintaining and Servicing any component of the Encon 

Evolution the instrument must be: 

 

 
1.

 

Turned off (Note:  Windows should be turned off properly.) 

2.

 

Disconnected from the Power Supply 

3.

 

Hot Surfaces should be given time to cool 

4.

 

After servicing instrument, all covers need to be placed back on the instrument. 

 

ATTENTION: Avant de maintenance et d'entretien tout composant de 

l'évolution Encon l'instrument doit être: 

1. Désactivé (Note: Windows doit être désactivé correctement) 

2. Déconnecté de l'alimentation 

3. Surfaces chaudes devraient avoir le temps de refroidir 

4. Après instrument entretien, tous les couvercles doivent être placés sur 

l'instrument.
