The following diagram illustrates what the different switches refer to so that the Nitro Express can be set up for the
proper situation.
The dip switches are set up so that the “up” position is “on” and the “down” position is “off”.

Rinse
The Rinse and Sanitizer knobs control the same setting
whether in probe or probeless mode and in door or conveyor
mode. They control the speed of the rinse and sanitizer pump.
The table to the right has approximate values for the pump
rate at different settings of the knob.
Only the DLL and LLL models have a sanitizer
potentiometer.

Initial Detergent Charge –
The detergent knob sets the time the
detergent pump will run or detergent valve will remain open during an
initial charge. The time can be set from 0-60 sec.
The initial charge is activated in one of two ways.
1.
It can be activated by 1 hour of elapsed time where no triggers have
activated the dispenser.
2.
With the rinse limit turned on (switch 7) and a rinse trigger active for
more than 20 seconds, an initial charge will be dispensed.
Dead Cycles –
The alarm knob sets the number of cycles no
detergent is dispensed before a recharge portion of detergent is added
to the machine.
The table to the right has the different settings for the Dead Cycle
count corresponding to the knob setting.
