Solution Tank
The standard
Solution Tank
holds 100 gallons [379
liters] of solution which
is gravity-fed through the
ball valve to the scrub
brushes.
The
Inlet Strainer
filters the
solution before it travels
from the
Solution Tank
to
the ball valve.
The
Drain Plug Assembly
plugs the drain hole to
the
Drain Hose
. The
Drain
Plug Assembly
uses an
expanding plug that
expands when the
Tee-
handle
is tightened (rotated
clockwise) to seal the drain
hole.
The
Drain Hose
is
supported by a hose holder
which swings out away
from the machine to free
the
Drain Hose
to drain the
Solution Tank
.
When the solution level in the
Solution Tank
is low, the
Solution Low Switch
will
actuate the
Low Solution Warning Light
on the instrument panel.
The solution tank also provides solution to the Power Spray Wand Option if the
machine is so equipped.
