7 .1 Housing
Check the housing for defects (switches, plugs) and clean it once a week with a damp cloth.
7 .2 Glass parts
Take out and clean the glass parts once a month or if required with commercially available cleaning
agents or in an ultrasonic bath. After the glass parts have been cleaned and fully dried, check each
part visually for cracks, scratches and for any parts or sections that might have splintered off. Take out
and replace any damaged glass parts.
7 .3 Hoses / hose connectors
Visually examine the hose connections regularly. When hoses become cracked and brittle, replace
them with new hoses.
Grease all joints on the condenser side regularly to achieve optimum tightness of the system.
Flush out the hoses at least once a week with water or ethanol.
For the
ECO
-versions check the cooling water hose for tightness and clean the sieve of the adapter on a
regular base.
7 .4 Sealing system
ATTENTION
When removing and reinstalling the seals and gaskets, make sure not to damage them. Always move
them perpendicularly to the axis of the glass parts and ensure no damage occurs to the sealing lip.
Never apply grease to the seals and never touch them with sharp objects, otherwise they will get
damaged.
7 .4 .1 Cleaning the gaskets
To prolong the lifetime of the gaskets (lip-gasket, gasket ring), rinse them at least once a month or if
required (e.g. when exchanging the washing solution) with water, especially if working with crystalline
products. Afterwards, dry them with a soft cloth.
7 .4 .2 Replacing the seals / GL 14 connector
Seals are subject to wear and tear, thus you should check them regularly and replace them, if neces-
sary, e.g. if the system becomes untight.
We recommend to replace the seals periodically as follows:
