1 8/09 Instructions Subject: Model MD2000 Support Stand INTRODUCTION The Multiplex MD2000 Support Stand is a compact rack storage system. This rack system provides storage for twelve (12) Bag-In-Box complete with Beverage Pumps and Change-Over Valves. The other standard components provided with this stand include a Water Accumulator Tank and a C02 Supply Control Panel. The Water Accumulator Tank maintains a constant water pressure to the system. The C02 Supply Control Panel provides a regulated C02 supply to the Beverage Pumps as well as to the Soda Factory The accessories for the MD2000 Support Stand include an Air Compressor, a Water Booster Pump, a Water Filter Package, and a C02 Tank Bracket. This Stand is designed to mount most of the components directly to the stand. The accessories may be mounted to a wall if the store layout requires.

2 NOT NOT NOT NOT NOT! Caution To Avoid Serious Injury Read the following warnings before beginning an installation. Falure to do so may result in possible death or serious injury. Adhere to all National and Local Plumbing and Electrical Safety Codes. Turn Off incoming electrical service switches when servicing, installing, or repairing equipment. Check that all flare fittings on the carbonation tank(s) are tight. This check should be performed with a wrench to ensure a quality seal. Inspect pressure on Regulators before starting up equipment. Protect eyes when working around refrigerants. Use caution when handling metal surface edges of all equipment. Handle C02 cylinders and gauges with care. Secure cylinders properly against abrasion. Store C02 cylinder(s) in well ventilated areas. Throw or drop a C02 cylinder. Secure the cylinder(s) in an upright position with a chain. Connect the C02 cylinder(s) directly to the product container. Doing so will result in an explosion causing possible death or injury. Best to connect the C02 cylinder(s) to a regulator(s). Store C02 cylinders in temperature above 125 F (51. 7 C) near furnaces, radiator or sources of heat. Release C02 gas from old cylinder. Touch Refrigeration lines inside units, some may exceed temperatures of 200 F (93.3 C). NOTE: Water pipe connections and fixtures directly connected to a potable water supply shall be sized, installed and maintained in accordance with Federal, State, and Local codes.! Warning DANGER OF ELECTRICAL SHOCK - Disconnect and lock out all electrical power sources before performing service or maintenance on this machine -- except when electrical tests are being performed by qualified service personnel.

With the Roll-out tray pulled out, remove the top cover and locate the Syrup Supply Lines. 2. Route the tubes out of the side conduit opening and bundle these lines together. 3. Loop the bundle towards the tray and then back to the pump panel. This ensures there is enough length to allow the tray to roll in and out. 4. Connect the product supply lines to the pump. Be sure the match the numbers on the lines to the numbers on the pump. 5. Clamp the lines in place using the clamps provided with the Refrigeration install kit. Connecting the Recirculating Conduit 1. Locate the Recirculating Conduit at the conduit chase. For overhead conduit, route the conduit through the square hole in the top of the upper rack and down the back side of the stand. 2. Loop the conduit towards the tray and back up through the side conduit opening to guarantee there is enough length to allow the tray to roll in and out. 3. Connect the conduit to the cooling coils per the installation instructions provided with the Refrigeration Unit. Loading the Bag-In-Box Syrup Supply The numbering configuration for the Bag-in-Box is the odd numbers go on the top shelf and the even numbers are on the bottom. Each syrup flavor will require two (2) Bag-inBox on the shelf, side by side. Load the shelves with the required products and install the connectors to the Bag-inBox. STARTING THE SYSTEM UP The system should now be ready for start-up. The Refrigeration Unit installation instructions will provide the steps required to start the System. After completing those instructions, the Multiplex MD2000 Support Stand System installation is complete.
