Solution System 328 Service Manual – CS7000
The
Solution Supply Line
supplies solution
from the
Solution Tank
to the
High-pressure
Pump
. The
High-pressure Pump
pumps the
solution to the
Relief Valve
which functions
as follows:
• If the trigger valve on the
High-pressure
Wand
is open, the solution flows through
the
Hose Coupler
and to the attached
High-pressure Wand
.
• If the trigger valve on the
High-pressure
Wand
is closed, the
Relief Valve
directs the
solution into the
Solution Return Line
and
back into the
Solution Tank
.
Note that the
Relief Valve
is pre-set at the
factory and is not adjustable.
Extended Scrub System
When the
Extended Scrub Level
(float)
Switch
inside the
Recovery Tank
closes to indicate
adequate water level, the
Extended Scrub
Pump
switches on to pump water to the
scrub brushes. The water passes through
the
Strainer
inside the
Recovery Tank
,
then through the
Water Supply Line
in the
Bulkhead Plates and Gasket
to the inlet side
of the
Extended Scrub Pump
. Note that the
second piece of conduit in the
Bulkhead Plates
and Gasket
is for the
Extended Scrub Level
Switch
wires.
The
Extended Scrub Pump
is mounted to a
bracket outside of the
Recovery Tank
. The
water from the
Extended Scrub Pump
is
plumbed into the solution line upstream of
the solution solenoid valve.
