VACUUM
NORMAL OPERATING MODE - HOW IT WORKS
In Normal Operating Mode, water is dispensed to the floor from Tank 1, vacuumed up and collected in Tank 3.
Sensors in the tank will detect when it is full, causing the High Recovery warning light to come on, and triggering
the transfer pump to send screened water from Tank 3 to Tank 2. When its sensor detects Tank 2 is full, the transfer
pump is shut off and Tank 3 continues collecting recovered water until its sensor detects it is full and the High
Recovery warning light comes on.
THE HIGH CAPACITY SYSTEM - HOW IT WORKS
In High Capacity mode, water is vacuumed from the floor and collected in Tank 3. Sensors in the tank detect when
it is full, triggering the transfer pump and transferrring water to Tank 1. When its sensor detects Tank 1 is full, the
High Recovery warning light comes on; Tank 1 valve closes and Tank 2 valve opens, allowing water to be pumped
into Tank 2. When its sensor detects Tank 2 is full, the High Recovery warning light comes on and the transfer
pump is shut off. Tank 3 continues to collect recovered water until it is full, when the High Recovery warning light
comes on.
ESP (RECYCLING MODE) - HOW IT WORKS (see below)
In Recycling Mode, water is dispensed from either Tank 1 or Tank 2 depending on the position of the ESP Switch.
If the switch is in Position 1, solution will be dispensed from and recycled back to Tank 1; Tank 2 is initially unused.
If the ESP switch in in Position 2, water will be dispensed from and recycled back to Tank 2; Tank 1 is initially
unused. Recovered water is collected in Tank 3. When the sensor identifies Tank 3 is full, the transfer pump is
activated and begins pumping recycled water to Tank 1 or Tank 2 depending on the switch position. When the
quality of the water recycled back to the first tank used becomes poor, the ESP switch should be moved to the
alternate position. This engages the unused second tank of clean water and the recycling process begins again,
further extending the scrubbing cycle.
