SRS SOLUTION TANK
The tank has a capacity of 265 gal (1000 L).
When the tank is full, a ball float will rise and shut
off the vacuum to the tank. A 72 in (1830 mm)
long drain hose for the recovery tank is located on
the front of the tank. You can determine the water
level in the tank by lowering the hose end until
water appears--this will then be the water level in
the tank (motor must be be off; this stops
vacuum). To drain the tank, lower the hose and
place near a suitable floor drain.
Empty and clean the solution tank and flush the
laminar tubes daily.
Partially fill the solution tank with clean water. Run
the SRS pump for a few minutes to flush the
solution hoses.
NOTE: The water must not be hotter than 130

DRAINING SOLUTION TANK
A. Drain Hose
B. Clean out Door
Six clean-out doors are provided on the tank, two
at the front, two at the upper rear, and two at the
lower rear of the tank. Using the sludge removal
tool, remove all sand, sludge, debris, etc., from
the tank. Remove the two large plugs above the
tank tires near the upper front of the tank. Flush
the sediment from all compartments of the tank,
and the wire mesh filters. Check for dirt buildup in
the laminar flow tubes. To clean tubes, remove
and flush. Also, check the return hoses and
connections for clogging or damage.
NOTE: For machines below serial number
004934, when replacing the clean-out doors, the
thumbscrews should be tightened to 20 -- 50 in lb
(2.26 -- 5.65 Nm). Do not over-tighten. Too much
torque on the thumbscrews will cause the
clean-out doors to bow and cut the door seals.
