This product is designed only to be used as described in this instruction sheet. Adhere to all warnings and
cautions identified in this document.
WARNING: Electrical and grounding installation of DEMA products must comply with
electrical codes and regulations established by national, city, county, parish, provincial or
other agencies. It is possible that electrical codes and regulations require that a certified
electrical contractor or engineer perform the electrical installation.
For questions, contact a certified electrician.
DISCONNECT ALL ELECTRICAL POWER TO THE DISPENSER AND THE APPLIED
MACHINE WHEN SERVICING- FOLLOW LOCKOUT / TAGOUT PROCEDURES.
WARNING: Installations must conform to all local and national plumbing codes and use
approved backflow prevention and pressure relief devices where required.
ALWAYS DISCONNECT DISPENSER FROM WATER SOURCE WHEN DISPENSER
IS NOT IN USE.
Always read SDS for all chemicals used and follow personal protective guidelines.
Note: All European installations must be carried out by a certified electrical engineer. All
other installations must be installed according to local country, city, state, or provincial
electrical codes. For questions please contact a local contractor.
1. BEFORE GOING ANY FURTHER, ALL ELECTRICAL POWER MUST BE TURNED OFF
TO THE DISH 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 CHEMASTER UNLESS POWER HAS
BEEN TURNED OFF. SIGNALS MAY BE PRESENT FROM DISH MACHINE, EVEN
WITH THE POWER TURNED OFF. ONLY USE ELECTRICAL CODE APPROVED
INSULATED WIRING AND ELECTRICAL FIXTURES WITH THIS INSTALLATION.
2. Install the power to the detergent board of the Chemaster, using the correct cable (refer to local
electrical code). In most applications, the pump contactor on the dish machine can be used to
power the detergent control. The power may be 120, 208 or 240V 50/60Hz. Route the cable away
from heaters and sharp edges. The cable should be mounted into the Chemaster enclosure using an
appropriate strain relief or conduit fitting. The cable should be connected to the proper detergent
terminal connections.
Note: A Nonmetallic enclosure does not provide grounding between conduit connections. Use
grounding type bushings and jumper wires.
3. Repeat step number 2 for the rinse side of the unit, connecting in parallel to the rinse solenoid
valve of the machine.
4. Route a two-core cable from the terminals on the detergent board marked Probe, through the
enclosed cable gland, to the probe. Fasten the two leads to the probe using the enclosed
compression fittings. Connection must be tight but over tightening can damage the probe.
