The [

SEC REMAIN

] readout displays the number of seconds left to go in the 

current automatic cleaning cycle.  It counts down as the cycle progresses.  If the 
machine is not running a cycle, it displays the programmed length of the cycle as 
selected on the [

CYCLE SELECT

] button.  This gives a convenient way to make 

sure the selected cycle is set to the desired length. 
 
The [

SHUTDWN TMR

] indicator displays [

PUMPS STOPPED

] if the machine 

has entered the Shutdown mode.  In this mode, the pumps are stopped, waiting for 
the beginning of a new cleaning cycle.  It displays [

RUN

] if the machine is not in 

shutdown.  See Section 

III.6 

for additional information. 

 

NOTE:

  The pumps will not run if the fluid level is low (this is to prevent the 

possibility of running the pumps dry).  If the pumps fail to run, check the      
[

FLUID LEVEL

] indicator first, and add fluid if necessary.  See Section

 III.4, 

Step 

12

 for information on adding fluid.  It is also possible that the system is in the 

Shutdown Mode.  Check the [

SHUTDWN TMR

] indicator.  If it says [

PUMPS 

STOPPED

] briefly touch both yellow buttons to turn the pumps on again.  The 

[

SHUTDWN TMR

] indicator will then indicate [

RUN

]. 

 
The DRYER [

START

] button is used to start the Dryer.  It displays [

RUNNING

while the dryer is running. 
 
The DRYER [

STOP

] button stops the dryer.  The dryer will run for the full period 

as set on the [

DRYER TIME

] button on the “Timer Setup” Screen unless this 

[

STOP

] button is pressed to stop it earlier. 

 
The readout below the DRYER [

STOP

] button displays the number of seconds 

remaining in the current dryer cycle.  It is color coded the same as the [

SEC 

REMAIN

] readout so as to indicate its similar function.  If the dryer is not running, 

it displays the programmed length of the dryer cycle in seconds. 
 
The three remaining indicators report the position of the lift arm.  There are separate 
indicators to show when the arm is at either the TOP or bottom (BOT).  If the arm is 
not at either of these points, the MIDWAY indicator will light. 
 
 

Machine Security Code 

 
The machine’s Security Code is shown on Page 26.  That page may be removed 
from the manual to secure the code if desired.
