The

 [FLUID LEVEL] 

button/indicator reads [

OK

]

 

when there is sufficient fluid in 

the overflow (front) tank.  Should the level drop too low, the indicator will turn red 
and flash the word [

ADD

].  After adding a quantity of fluid at the correct dilution to 

the front tank, depress the indicator to reset it to [

OK

]. 

 

NOTE

:  If the machine has just been filled, it might be necessary to depress the 

[

FLUID LEVEL

] indicator to clear the [

ADD

] indication. 

 
The 

[PUMPS]

 switch is provided to control the pumps.  After initially filling the 

machine, and clearing the [

ADD

] indication as described above, the [

PUMPS

switch should be turned on (indicated by the numeral 

[1]

) to begin circulation.  If the 

machine is expected to be idle for long periods, the pumps can be turned off to save 
evaporative loss of fluid, save energy, and reduce wear and tear on the equipment.    
See also Section

 III.6 

for information on the Shutdown Timer. 

 
The [

MAIN FILTER

] indicator shows the state of the main filter, the long housing 

on the left.  If it is displays [

The [

OVRFLO FILT

] (Overflow Filter) indicator shows the state of the overflow 

tank’s filter, the long housing on the right.  If it is displays [

CHANGE

] the filter 

cartridge should be replaced.  This condition does not prevent operation.  The state 
of this indicator is controlled by pressure switch 

PS2

.  The indicator will not be 

visible if the pumps are not running. 
 
The 

[AUTO CYCLE]

 button enables and disables the Automatic mode of the 

machine.  To run automatic cycles, this button must read 

[ENABLED]

.  When 

automatic cycles are not enabled, this button will flash the word 

[DISABLED]

 
The 

[READY]

 indicator indicates if the cleaner is ready to run automatic cycles.  

For this indicator to be on, the following conditions must be met: 

 
1.

 

The [

PUMPS

] switch must be ON 

[1] 

(but the pumps might not be 

running.) 

2.
