Detergent System Controls and Indicators
•
Detergent Strength Switch
– functions as follows:
• When the scrub system is enabled, pressing
the
Detergent Strength Switch
will cycle the
detergent flow rate from weak (bottom box
filled as shown), to strong (top and bottom
boxes filled), then to off (no boxes filled).
• When the scrub system is not enabled
(machine in transport mode), pressing
and holding the
Detergent Strength Switch
and Solution Flow Adjustment Switch
simultaneously will enable the purge mode.
•
Detergent On/Off Indicator
– indicates that the detergent flow rate is a rate other than zero.
•
Detergent Indicator Bar Graph
– displays the detergent flow rate, ratio and percentage on the graphic
display as follows:
• Bottom box filled – weak detergent flow rate (as shown).
• Top and bottom boxes filled – strong detergent flow rate.
• Both boxes empty – detergent system off.
•
Detergent Purge Screen
– displays the
Chemical Purge Icon
to
indicate that the detergent purge cycle is active. To start
the purge cycle and display the
Detergent Purge Screen
, press
and hold the
Detergent Strength Switch
and the Solution Flow
Adjustment Switch simultaneously for three seconds. The
Detergent On/Off Indicator
will flash and the purge cycle will last
for approximately 10 seconds.
Burst of Power Switch and Indicator
•
Burst of Power Switch
– temporarily overrides the current machine
settings to increase the machine’s cleaning aggressiveness by
performing the following:
• Increases the scrub pressure from standard pressure to extra
pressure.
• Increases the solution flow rate by one level (off to low, low to
medium or medium to high).
• Increases the detergent flow rate to the strong level (off to
weak or weak to strong). Note that this will only happen if the
detergent option is installed.
• Increases the vacuum power from low/quiet to high/standard. Note that the vacuum motor will not
switch from off to low/quiet because of the assumption that if the vacuum is off, the user must be in
double-scrubbing mode and wishes to stay in that mode.
If any one of the functions listed above is already performing at its maximum possible rate, the
Burst of
Power Switch
will have no effect on that function but will still affect the other functions. If the detergent
option is not installed, the Burst of Power will not affect detergent flow but will still affect the other
functions.
