Introduction
The DEMA 844P Laundry Master dispensing system has been designed to accurately deliver chemical
product to commercial laundry machines. The 844P uses the proven DEMA Quick Change peristaltic
pumps to deliver the chemical product to the laundry machine pocket. The Quick Change pumps and
main control are mounted in a durable and attractive ABS enclosure designed to provide easy access to
the various components inside.
The various electronic components of the DEMA 844P Laundry Master use a “plug and play” concept to
provide easy setup. The heart of the 844P is the IQ-85 electronic control board that provides 30 wash
formula capability. The IQ-85 is mounted in the ABS enclosure with the display and buttons available on
the front panel. Along with the IQ-85 is the self contained Signal Transfer Unit (STU), which can be
mounted at the laundry machine to receive trigger signals. Additionally, a handheld Enhanced Digital
Select Module (EDSM) is available to allow the user to interface with the system remotely. Both the STU
and the EDSM are connected to the IQ-85 via a low voltage communication cable.
844P Laundry Master Contents
The DEMA 844P Laundry Master includes the following:
•844P Dispensing System, which contains the pumps, the power supply, and the IQ-85 electronic
control board
•Hookup Kit, which contains communication cable, Velcro fasteners, various strain reliefs and wire
ties.
•Signal Transfer Unit (STU), for receiving trigger signals and sending commands back to the IQ-85
•Optionally, the 844P Dispensing System will come with an Enhanced Digital Select Module
(EDSM), for all programming functions, selecting 30 formulas, defeating bleach, and emergency
stop remotely.
•Optional Kits:
Tubing and pickup probe kit can also be provided which comes with 20ft of LDPE tubing per

Laundry Room Survey
A complete survey of the laundry room or site installation should be completed in advance of starting the
Laundry Master installation.
1. Locate the power connection points on the laundry machine. The main power to the Laundry
Master must either be 120V or 230V 50/60Hz (+10%/-15% for voltage is acceptable).
2. Select a location to mount the Laundry Master enclosure on a wall that will allow access to the
chemical product containers and the chemical product feeds points on the laundry machine. The
Laundry Master should be kept away from moisture releasing machinery and from water being
splashed on the unit.
3. Mount the Laundry Master on a wall by use of appropriate screws and wall anchors.
4. Select a location to mount the Signal Transfer Unit (STU). The STU should be mounted close to,
or on, or possibly inside the laundry machine. The STU will need to be wired to the various
trigger signal sources on the machine. The trigger wires that are coming out of the STU are 36
inches in length and are used to receive the trigger signals. The STU can be mounted by use of the
self-adhesive Velcro that is included in the hook up kit. Keep in mind that the STU is wired to the
IQ-85 via the supplied communication cable.

5. If using the EDSM, select a location to mount the EDSM where the laundry machine operator can
easily access the buttons on the front of the EDSM module. Again, it can be mounted with the
self-adhesive Velcro that is included in the hook up kit. The EDSM can be connected to the IQ-85
or the STU by use of the supplied communication cable. See the EDSM instruction manual for
more information.
6. If using the DEMA 950 flush manifold or any other flush manifold , select a location that will
allow all the electrical (power for solenoid valve and pressure switch) and tubing connections. It
should be noted that the flush output on the IQ-85 is a 24VDC signal. The solenoid coil for the
flush valve will need to match this output signal.
Cleaning Instructions
Do not expose inside of unit to moisture! Do not expose unit to direct water/chemical spray! Clean
external shell with damp cloth.
844P Pump Configurations
The pumps are numbered 1 through 6 from left to right.
Electrical Installation
All installations must be in accordance with city, county, parish, state or provincial electrical codes and
should be performed by a certified electrician. A ½” nonmetallic conduit system must be used to install
the power cord. For questions, please contact local licensed electrical contractor.
Before the electrical installation, it is important to understand the various modes that the 844P Laundry
Master has to offer. The following describe the 3 main modes, however there are sub-options that can be
set up within these 3 modes. See the setup section for additional information.
Formula Select Mode:
This is where the unit can be programmed with up to 30 different formulas. Each formula is
driven to operate by individual trigger sources that are generated by the laundry machine.
Sequence Mode:
This is where the unit can be programmed to count a single event from the laundry machine. A
good example of this is using the drain valve on the laundry machine as a trigger source. The IQ-
85 will count the drain valve operations and will operate pumps based on these counts. Up to 30
formulas can be programmed in this mode as well.
Relay Mode:
There is only one programming variable to set on the IQ-85. A flush can be set to run with, and
for an additional time after, each pump operation. Otherwise the IQ-85 is not programmed, but
instead the laundry machine is programmed to provide various formulas. The IQ-85 acts like a
relay board and will only operate pumps for the length of time that the STU receives a trigger
signal from the laundry machine.

Auto Formula Select
One sub-option to become familiar with before wiring the STU is Auto Formula Select. This
feature allows the formula to be selected based on a trigger signal that is received from the laundry
machine. It is necessary to have a separate programmable input from the laundry machine to
correctly use the Auto Formula Select. For more information, see Auto Formula Select section in
this instruction manual.
1. CAUTION: All electrical power must be turned off to the laundry machine and any other
circuit that is to be used for this installation. Lockout and tag procedures must be observed
when installing this device. Never open the DEMA Laundry Master while power is applied.
Signals may be active from laundry machine, even with the DEMA Laundry Master power
turned off. Use appropriately rated insulated wiring, electrical fixtures and other materials
that meet all applicable electrical and building codes.
2. Connect the power to the Laundry Master. The power requirement is from 100VAC to
240VAC 50/60 Hz. Power should be applied to Laundry Master anytime the laundry machine is
on. Some laundry machines have a terminal block setup for power (see schematic or owner’s
manual for the specific machine being used). Locate the power terminal block inside the Laundry
Master enclosure. Connect “hot” or “live” wire to the terminal labeled “L1”. Connect the
“return line” to the terminal block position labeled “L2”. The ground wire MUST be
connected to a suitable earth ground point. The power line should be secured by use of proper
electrical fitting through access hole in Laundry Master enclosure. The access hole is sized to
accept a ½” conduit fitting. The power line must also be secured properly between the laundry
machine or power source and the Laundry Master according to any electrical codes that apply.
3. Connect the flush manifold. See note labeled flush switch below if a flush manifold is not being
used. If using a flush manifold, the solenoid valve that supplies the manifold must be rated for
24V DC. The valve should be connected to the output terminal position labeled “FLUSH” on the
IQ-85 control board. In addition, a manifold flush switch must be wired to the terminals labeled
“Flush SW” on the IQ-85 control board.
Flush Switch: When a flush manifold is not used, step number 3 can be skipped. However, it is
essential that a jumper be connected between the “Flush SW” terminals on the IQ-85 control
board. The jumper is installed at the factory. Examine the unit to be installed to assure that it has
the jumper installed. Without the jumper, the Laundry Master pumps will not run. If a jumper
needs to be installed, use a short piece (2-4 inches) of insulated 18GA electrical wire stripped
approximately 3/16” at each end.

4. Wire the STU to the laundry machine. The hookup configuration will depend on
which of the operational modes the DEMA 844P Laundry System will be used. The
following two tables show the wiring configurations for the input signals to the
STU. The first is for normal and relay modes and the second is for sequence mode.
Verify the mode that will be used and wire the STU according to the appropriate
table below using the leads that are coming out of the left side of the STU. Keep in
mind that trigger sources should be at least 24VAC but no higher than 240VAC
50/60Hz.

5. Auto Formula Select. This allows the formulas to be selected based on a trigger
signal that is received from the laundry machine. The following list outlines the
setup of this feature: The 8th trigger input on the STU is used for this purpose (see
table in the electrical installation section of Laundry Master Instruction Manual). A
trigger source that can be programmed at the laundry machine will be required. The
timing of this trigger source is what determines which formula is selected by the IQ-
80. To determine the amount of signal time for any formula simply calculate as
follows: i. Multiply the formula number by 2 then subtract 1
1. Example: Formula 7 needs a trigger signal equal to 13 seconds.
(7 X 2 = 14 then 14-1 = 13). A 13 second trigger signal to STU
input number 8 (purple and purple striped wires) will change the
Atlas to formula 7.
6. Connect the EDSM (See EDSM instruction manuals for more details) and STU modules to the IQ-
85 by using the RJ45 patch cords that are supplied with the Laundry Master. The STU is required
in all installations, but the EDSM is optional. It is possible to connect the EDSM to the STU RJ45
jack instead of connecting to the IQ-85, providing that the STU is connected to the IQ-85. See the
following note concerning the EDSM.
EDSM Note: The EDSM module is a hand held, remote control that gives the operator the ability
to select formulas, defeat a bleach operation, or do an emergency stop. It is not necessary to use it,
but without the EDSM the only way to manually select a formula would be to select it at the IQ-85
board in the front of the enclosure.
Note: The patch cord is a communication link between the IQ-85 board, the STU and the EDSM
and can be subjected to electrical interference when not installed properly. When securing the
RJ45 patch cord between the On-Premise Laundry Controller and the Laundry Master, avoid sharp
edges, electrical motors and relays; additionally do not run parallel to electrical power lines and
conduit.

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.
