Filtration And Sump Sweep Systems
(Optional)
The filtration and sump sweep systems are options on
this machine. The filtration and sump sweep systems
reduce or eliminate the need to manually clean out the
sump. The filtration system continuously filters solid
particles from the wash solution, and then you can use
the sump sweep system to periodically remove waste
build up from the bottom of the sump chamber.
Filtration System
The filtration system uses a single or multiple-canister
configuration with nylon or polyester felt filter bags to
continuously filter solid particles from the wash
solution. The filter system includes pressure gauges
which allow you to monitor the condition and perfor-
mance of the filter bag(s) inside the canister(s). Under
typical operating conditions, the inlet and outlet
pressure gauges read approximately 45 psi. As the
filter system becomes clogged, the outlet pressure
decreases.
When the outlet pressure drops to 30 psi or less, stop
the machine and clean or replace the filter bag(s) (See
Cleaning the Filters ). Check filters daily.
WARNING: Operating the machine with a clogged
filter system could damage the filter bag. STOP
THE MACHINE IMMEDIATELY if the outlet pressure
drops to 30 psi or less.
AVERTISSEMENT: Utiliser la machine alors que le
système de filtration est obstrué risquerait d'endo
mager le sac du filtre. ARRÊTER IMMÉDIATEMENT
LA MACHINE si la pression de sortie chute en deçà
de 30 psi.
Sump Sweep System
The sump sweep system uses a three-way valve to
divert solution from the wash chamber to a spray bar on
bottom of the sump chamber. The spray bar generates
a high-pressure spray pattern that agitates the sump
solution and suspends solid particles. The solution then
flows through the filtration system which removes the
solid particles (
Filtration and Sump Sweep System ).
