Installation - DEMA Master Nitro Express Manual

Installation

WARNING: INSTALLATION OF DEMA PRODUCTS MUST MEET ALL APPLICABLE
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.
ALL ELECTRICAL POWER MUST BE TURNED OFF TO THE HEATING ELEMENTS AND DISH
MACHINE PRIOR TO BEGINNING INSTALLATION
UNIT MUST BE GROUNDED (EARTHED).
Mounting the DM Nitro Express
1. Mount the unit in an appropriate place on a wall using the enclosed mounting bracket and screws.
Setting up the DM Nitro Express and the Dish Machine
1. Locate the electrical connection point. The input power may be 100V – 265 V 50/60 Hz. Check with the
manufacturer of the machine to determine if there are dedicated terminals available for installation.
2. Properly ground the dispenser to earth ground.
3. If the Nitro Express will be operating in the concentration mode, locate the proper position for the DEMA C-
12B probe in the wash tank. The probe must be installed below the water level, normally 1-2" from the bottom
of the tank, and must be kept away from heating elements, pump intake, drains and incoming water supply.
4. Install the detergent injection bulkhead fitting (80-55) above the probe (if a probe is used) to obtain a rapid
reading of all chemicals entering the wash tank.
5. Install the rinse line injection fitting (904-8T) into the rinse line tap provided by the manufacturer of the
machine. If a tap is not provided, follow the manufacturer's recommendations for installing this fitting.
6. Install the sanitizer injection fitting (904-8KY) (if sanitizer is used) into the rinse line tap provided by the
manufacturer of the machine. If a tap is not provided follow the manufacturer's recommendations for installing
this fitting.
Connecting the Chemical Tubing to the Nitro Express
1. After mounting the dispenser, measure the length of tubing needed to go from the dispenser to the chemical
containers. The detergent tubing (25.68.20) is opaque in color and has a larger inside diameter than the rinse
and sanitizer tubing (100.12.SV1) which is clear in color and has a small inside diameter.
2. Cut the tubing to the length required and, if desired, place the pickup tube on the tubing before placing in the
chemical container.
3. Measure the length of tubing needed to go from the dispenser to the chemical injection point on the machine.
4. Cut the tubing to the length required to reach the bulkhead fitting or chemical injection point on the machine.
Wiring the Nitro Express to the Dish Machine
The following diagram is included to help to install the wires in the correct places for proper power for the unit.
WARNING: ONLY UP TO 265 VAC SHOULD BE SUPPLIED TO THIS UNIT. ANYTHING
OVER THAT AMOUNT WILL CAUSE CRITICAL DAMAGE TO THE UNIT.
WARNING: For safety purposes disconnect main power to the dish machine before wiring
trigger signals to the Nitro Express. Connect power to the Nitro Express per the dish machine
manufacturer's recommendations.
UNIT MUST BE GROUNDED (EARTHED).
The following steps will help to insure the proper wiring of the unit. The unit should be triggered to power on from the
dish machine that it is being used in conjunction with. DEMA Engineering does not recommend powering the unit
separately from the dish machine. The following three steps will insure that the unit only receives power when it is
necessary to have power to run the setup that is programmed in the unit.
