SYSTEM OVERVIEW
The DEMA 830 Laundry Master is designed for long reliable use with simplicity in mind for both the
installer and user. The system is based on the reliable DEMA peristaltic pump for liquid chemical or a
solenoid operated water valve for dry chemical. The pump or water valve is installed in a heavy plastic
housing with a sealed cover that uses a Lexan label for access of external control and visible indicators.
The pump is available in two different speeds, 60 and 105 RPM.
The control board will accept an AC or DC trigger signal from the laundry machine to control the
operation of the pump or valve. All units are equipped with a built in transformer with primary voltages of
120, 208, and 240 at 50/60Hz.
Please read all instructions before proceeding with Laundry Master installation.
LAUNDRY ROOM SURVEY
A complete survey of the laundry room or sight installation should be completed in advance of starting
the Laundry Master installation.
1.
Locate the power connection points on the laundry machine. This power must be between 95 and 250
volts 50/60Hz.
2.
Select location to mount the Laundry Master on a wall that will allow access to the chemical product
containers and the chemical product feeds points on the laundry machine. 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 the supplied hanger kit and screw and anchor kit.
Note: The supplied screw and wall anchors may not be suitable. The wall construction at point of
installation should be evaluated to determine the proper type of screw and wall anchor.
ELECTRICAL INSTALLATION
All installations must be in accordance with city, county, state or provincial electrical codes and be
performed by a certified electrician. For questions, please contact local licensed electrical
contractor.
1.
BEFORE GOING ANY FURTHER, 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 SHOULD BE OBSERVED
WHEN INSTALLING THIS DEVICE. NEVER OPEN THE LAUNDRY MASTER UNLESS
POWER HAS BEEN TURNED OFF. SIGNALS MAY BE PRESENT FROM LAUNDRY
MACHINE, EVEN WITH THE LAUNDRY MASTER POWER TURNED OFF. ONLY USE
ELECTRICAL CODE APPROVED INSULATED WIRING AND ELECTRICAL FIXTURES
WITH THIS INSTALLATION.
2.
Connect the power to the Laundry Master. This may be 120V, 208V or 240V 50/60Hz. 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 owners 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 “line”. Connect the “return line” to the appropriate terminal block position
based on supply voltage. The “earth ground” wire must be fastened to the terminal block bracket by
use of the supplied grounding clip. The power line should be secured by use of proper electrical fitting
