To maximize the value of this process and to therefore minimize paraffin
consumption, the
WPC
should be run after every process.
Important note:
The retort should be cleaned (using the Purge
Cycle following a process) prior to starting the
WPC
and the retort lid
MUST remain closed during the purification cycle.
Although there will be no paraffin in the retort, it is important to keep the retort closed
during the process to ensure proper functioning of the pneumatic (air) circuit. If you
must open the retort for some reason or if you wish to start a process before the
WPC
is complete, use the
ESC
key to halt the
WPC
before opening the lid.

Filter replacement is required approximately every 60 to 120 processes, based upon
environmental factors and use of the
WPC
. We estimate that:
•
Without
the use of the
WPC
, filter life will be from 90 - 120 processes
•
With
the use of the
WPC
, filter life will be from 60 - 90 processes
These values are only estimates because they are influenced by:
•
Environmental factors (humidity, temperature)
•
The duration of the processes
•
The application of the vacuum (or pressure) on all the steps of the process
•
The frequency of reagent agitation
Regardless of usage, the charcoal filters should be changed at least once every six
months. To order additional filters, specify Cat # 8A1850.
Exhausted filters must be replaced with the required frequency as they may release
toxic and contaminated vapors into the air if left too long.
Exhausted filter waste is to be handled in accordance with local, state and national
regulations.

The Retort lid gasket is made of VITON™ rubber (a DuPont trademark). It needs to
be periodically greased with TEFLON grease (Cat # 7PV999). When replacing, use
a sharp point – not a metallic one – to extract the gasket. Carefully clean the gasket
housing slot and replace the gasket with a new one.
