Overview
Overview
The ratio check kit is used in place of the static mixer or
hose that would normally be attached to the outlet of mix
manifold 258989.
The kit allows only the hardener to dispense out of the
normal outlet. The resin is diverted to dispense out of
the sample valve (2). The outlet plug (4) must be
removed before returning to “mix” mode.
Installation
NOTICE
To prevent an inaccurate ratio check when feed
pumps are used in your system, the feed pressure
cannot be more than a maximum of 25% of the proportioner outlet pressure. High feed pressure can
float the proportioner pump check balls, resulting in
an inaccurate ratio check.
1. Relieve pressure. See mix manifold manual for
instructions.
2. Flush mixed material, if necessary. See mix man-
ifold manual for instructions.
3. Remove plug (P3) from the mix manifold.
