Tubing Connections
ALWAYS WEAR PROTECTIVE CLOTHING AND SAFETY EYEWEAR WHEN WORKING
WITH CHEMICALS.
Included in the installation kit is a 20ft roll of LDPE tubing per pump to connect from the chemical
container, via the pump, and to the fittings on the machine.
Liquid Detergent (pump)
Measure the length of the tubing needed for the suction side from the chemical container to the inlet of
pump and cut the tubing to the proper length. Install LDPE tubing into pick-up tubes (gray PVC) through
compression nut until the tube is within ¼” of the other end of pickup tube. Tighten nut to secure. When
properly installed the LDPE tubing will not stick out the open end of pick up tube. Route the tubing to the
suction side of the pump and insert into squeeze tube approximately ½”. Secure the tubing together by
tightening a cable tie around the squeeze tube. Use the same procedure on the outlet of the squeeze tubing
and route the LDPE tubing to the injection feed points of the machine. Cut off all excess tubing and keep
tubing away from hot surfaces and sharp edges to prevent damage or leakage.
Dry Detergent (valve)
Use ¼” compression fittings to connect ¼” LDPE tubing between the outlet of the solenoid valve on
Laundry Master and the inlet of the siphon breaker on the dry chemical product dispenser.
At this point the Laundry Master installation is complete.
PROGRAMMING, OPERATION AND SETUP (Jumpers and Lockout Time)
General Operation
When a trigger signal is received from the laundry machine, the control will run its program. A two-
second delay will occur to make sure the trigger is not a false signal. The control will then delay
operation for the programmed delay time. This allows the laundry machine time to fill with water before
adding chemical. At the end of this delay the pump will run for the programmed time. The control will
then lockout, preventing re-triggering for programmed period of time.
Jumper Installation
See figure 1, 2, and 3 for proper jumper installation.
•
When the jumper is in the off position the board is setup for receiving triggers from the laundry
machine (See Figure 2).
•
When the jumper is in the on position, the control board is setup to operate using the DEMA optional
remote kit (See Figure 1).
