The “Manual Functions” screen also contains the control button for the Shutdown 
Timer.  The shutdown timer allows the user to automatically turn the spray pumps 
off after a period of time following the end of the cleaning cycle. 

 
Shutdown Timer Operation 

The 

[SHUTDWN TMR]

 button enables and disables the Shutdown Timer.  This 

button is a toggle function.  Push the button to alternate between Enable and 
Disable.  The default state of this button upon power up is Enable. 
 
The length of the interval is controlled by the 

[SHTDWN TIME]

 button on the 

“Timer Setup” Screen. 
 
When the arm has risen completely to the top at the conclusion of a cleaning cycle, 
and the 

[SHUTDWN TMR]

 button is in the Enable position, the machine will wait 

the amount of time set on the [

SHTDWN TIME

] button.  When this period of time 

has elapsed, the spray pumps will turn off.  On the Operations screen, the 
[

SHUTDWN TMR

] indicator will turn red and read [

PUMPS STOPPED

], 

indicating that the shutdown is in effect.  The filter indicators will be hidden. 
 
To run another cleaning cycle, mount the item in the lift arm and depress the two 
yellow buttons to lower it into the tank.  When the item reaches the bottom and the 
[

BOT

] indicator lights, release the yellow buttons.  The spray pumps will then start 

and the Filter indications will reappear on the Operations screen.  The [

SHUTDWN 

TMR

] indication will turn green and read [

RUN

]. 

 

NOTE:

 If the user wishes to turn the pumps back on without running a cleaning 

cycle, touch both yellow buttons briefly and the pumps will restart.  The 
[

SHUTDWN TMR

] indication will turn green and read [

RUN

].  The pumps will 

then run indefinitely. 
 
If it not desired to turn the spray pumps off when a cycle is over, simply push the 
[

SHUTDWN TMR

] button so that Disable is selected. 

 
To exit from the “Manual Functions” screen, press the [

+

] button twice and you will 

be returned to the Operations screen.
