Replacing Frit Filters
Totalflow recommends that a replacement analytical module
be installed at this point and additional steps be performed in
a clean, lint free atmosphere.
Because the customer does not have the required equipment
to determine which specific module needs replaced, the final
instructions are by process of elimination, beginning with the
most likely module.
The Totalflow repair department offers a range of services for
troubleshooting and repairing/replacing the non-functioning
parts. For more information regarding the repair service,
