Installation
b. Option 2, for continuous applications
when reservoirs are filled manually:
In this
configuration, the maximum working pressure
of the proportioner must be derated to 4000
psi (27.6 MPa, 276 bar). See the
Warning at
right. Reduce the maximum working pressure
setting in the SuperCat electronics to 4000 psi
(27.6 MPa, 276 bar) or lower (see page 41).
Install the heaters on the fluid lines between the
proportioner pump and the fluid cabinet. See Fig.
6. Also, pressure relief valves are required be-
tween the proportioner pump and the heaters, to
protect against overpressurization should the
heaters become plugged.
Fill the reservoirs manually. Set the heaters to the
desired temperature and begin spraying. With this
option, continuous spraying is possible.
WARNING
COMPONENT RUPTURE HAZARD
Do not exceed the heater’s maximum
fluid working pressure of 4000 psi (27.6
MPa, 276 bar).
Install Part No. 237074 Pressure Relief Valves on
the fluid lines between the proportioner pump and
the fluid heaters, to prevent overpressurization
should the heaters become plugged.
