Tubing Connections
ALWAYS WEAR PROTECTIVE CLOTHING AND EYEWEAR WHEN WORKING WITH
CHEMICALS PRODUCTS.
An optional installation kit may be ordered with the 844P Laundry Master. The kits includes a 20ft of
LDPE tubing per pump to connect from the chemical container to the DEMA 844P pump, and from the
DEMA 844P pump to the fittings on the machine and 18” pickup tubes designed to accommodate 5 gallon
buckets.
For identification purposes, the pumps are identified starting with 1 and up to a possible 6 depending on
the model. In all cases pump number 1 is the pump that is furthest left, count up as you see pumps to the
right of this position. Included with the 844P Laundry Master is a sheet of product labels that can be
adhered to the front of the Laundry Master or any other useful locations to identify the product that each
pump is supplying.
Measure the length of tubing needed for the suction side from the chemical container to the inlet of the
pump and then cut the tubing to the proper length. The 18” pickup tubes may be used with 5-gallon
buckets of chemical products. Feed the LDPE tubing through the compression nut and sleeve and into the
pickup tube until the LDPE tubing is about a ¼” from the bottom of the pickup tube (LDPE tubing should
not stick out through the bottom of pickup tube). Tighten the compression nut to secure LDPE tubing.
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 tube and route the LDPE tubing to the injection feed points of the laundry machine.
Cut off all excess tubing and keep tubing away from hot surfaces and sharp edges to prevent damage or
leakage.
At this point the Laundry Master installation is complete. See IQ-85 OPL Laundry Control Board
instructions for setup and programming.
Laundry Master Operation
Once the system has been programmed and set up to the desired configuration the 844P Laundry Master
is ready for operation.
Priming the Pumps
There are two ways to prime a pump. The first way, is to press the LEFT arrow on the front of the 844P.
“P1” will be displayed indicating pump 1. Use the UP and DOWN arrows to select the desired pump.
Press the ENTER button to start and stop the pump. Pressing the RIGHT arrow will return the 844P to
formula select mode. If no action is taken in the pump priming mode the 844P will return to formula
select mode after 30 seconds. The second way, is to use the EDSM (Enhanced Digital Selection Module).
Refer to the EDSM Instruction Sheet I-901.
Emergency Stop
At anytime, the pumps and flush can be stopped by pressing the “STOP” button on the EDSM. When
pressed, it will also reset the system to a starting point of the formula.
