Programming
It is helpful to know the amount of chemical product to be dispensed before programming the Laundry
Master. To assure that a specific application is satisfied, it is recommended that the output rate of the
specific chemical product be measured by use of a graduated cylinder.
The programming function will set the delay time and the amount of time that the pump will run when a
trigger signal is received from the laundry machine.
1.
Note that the front face of the Laundry Master has a button labeled “
PROG/PRIME
” and a round
window labeled “
CHARGE
”.
2.
Press and hold the “PROG/PRIME” button to activate the programming function. The “
CHARGE
”
light will illuminate. Continue holding the button for about 8 seconds until charge light goes out,
turns on, and then begins flashing. Release the button.
3.
The “
CHARGE
” light will continue to flash. The delay time is now being recorded. This time can be
set between 0 and 4 minutes 15 seconds.
4.
Press the “PROG/PRIME” to stop the delay time. The pump will begin to run. The pump run time is
now being recorded. The minimum amount of time is 10 seconds and the maximum amount of time is
4 minutes and 15 seconds.
5.
Allow Laundry Master to pump for the desired amount of time. Push the “
PROG/PRIME
” button to set
that amount of time and exit the programming function.
