About Typical Installations
The typical installations shown below and on page 7
are only guidelines to setting up a complete VRHC
system. For clarity, various components are shown in
the correct order but may not be shown in the exact
position of the installed system. For assistance in
designing your system, contact your nearest Graco
representative.
NOTE: When pressure feeding the proportioning
pump, mount fluid pressure gauges (J) at the propor-
tioning pump inlets to monitor proper adjustment of the
feed pump pressures. Never exceed 400 psi on the
inbound fluid pressure and never exceed 25% of
the Hydra-Cat pump outbound fluid pressure on
the feed supply.
