Carbon Dioxide (CO2) displaces oxygen. Exposure to a high concentration of CO

gas causes tremors,

which are followed rapidly by loss of consciousness and suffocation. If a CO

gas leak is suspected,

particularly in a small area, immediately ventilate the area before repairing the leak. CO

lines and pumps

must not be installed in an enclosed space. An enclosed space can be a cooler or small room or closet. This may include convenience stores with glass door self serve coolers. If you suspect CO

may build up in an area, venting o f the BIB pumps and/or CO

monitors must be utilized.

KITCHEN EQUIPMENT INSTALLER REPRESENTATIVE RESPONSIBILITIES

Prior to scheduling Multiplex Equipment installer, the following steps listed below must be completed:

1. Electrical power supply meeting the requirements for the unit to be installed. (See the specification in this section or refer to the unit’s serial plate).

2. CO

Gas (bulk or bottled supply); minimum 3/8" line.

3. A 120 VAC, 3-wire, 1 Phase, 60 Hz dual wall receptacle for optional electrical equipm ent (domestic only).

NOTE: Do not schedule the authorized Multiplex Equipment Installer until all of the above have been completed. It will only result in charge-backs to you for the unnecessary trips.

Installer Instructions

The remainder of these instructions is to be completed by an authorized Multiplex Installer.

These equipment instructions are intended to assist qualified personnel in the unpacking, locating and the initial operation of the Multiplex Beverage Equipment Refrigeration Unit.

This publication must be saved for future reference. Read instructions before attempting installation.

PREPARATION

The Multiplex Beverage Equipment Refrigeration Unit is pre-assembled in the factory and requires minim u m installation.

For future reference or to be used when ordering parts, record the Model Number, Serial Number, Part Numbers of Unit, Condenser (if remote), Towers, etc., an d Date of Installation on the inside of this Manual. Leave manual on site in a safe place. Do not discard manual.

Ambient Location Requirement

This equipment is rated for indoor use only. It will not operate in sub-freezing temperature. In a situation when temperatures drop below freezing, the equipment must be turned off immediately and properly winterized. Contact the manufacturer for winterization process.

Electrical

GENERAL

All wiring must conform to local, state and national codes.

MINIMUM CIRCUIT AMPACITY

The minimum circuit ampacity is used to help select the wire size of the electrical supply. (Minimum circuit ampacity is not the beverage/ice machine’ s running amp load.) The wire size (or gauge) is also dependent upon location, materials used, length of run, etc., so it must be determined by a qualified electrician.

ELECTRICAL REQUIREMENTS

Refer to Ice Machine Model/Serial Plate for voltage/amperage specifications.

GROUNDING INSTRUCTIONS

When using electric appliances, basic precautions

The beverage/ice machine must be grounded in accordance with national and local electrical codes.

This appliance must be grounded. In the event of malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This appliance is equipped with a cord having an equipment-grounding conductor and a grounding plug. The plug must be plugged into an appropriate outlet that is properly inst alled and grounded in accordance with all local codes and ordinances.

Improper connection of the equipment-grounding conductor can result in a risk of electric shock. The conductor with insulation having an outer surface that is green with or without yellow stripes is the equipment grounding conductor. If repair or replacement of the cord or plug is necessary, do not connect the equipment-grounding conductor to a live terminal. Check with a qualified electrician or serviceman if the grounding instructions are not completely understood, or if in doubt as to whether the appliance is properly grounded. Do not modify the plug provided with the appliance — if it will not fit the outlet, have a proper outlet installed by a qualified electrician.

must always be followed, including the following:

a. Read all the instructions before using the

appliance.

b. To reduce the risk of injury, close supervision is

necessary when an appliance is used near

children. c. Do not contact moving parts. d. Only use attachments recommended or sold by

the manufacturer. e. Do not use outdoors.

f. For a cord-connected appliance, the following

shall be included:

• Do not unplug by pulling on cord. To unplug, grasp the plug, not the cord.

• Unplug from outlet when not in use and before servicing or cleaning.

• Do not operate any appliance with a damaged cord or plug, or after the appliance malfunctions or is dropped or damaged in any manner. Contact the nearest authorized service facility for examination, repair, or electrical or mechanical adjustment.

g. For a permanently connected appliance — Turn

the power switch to the off position when the appliance is not in use and before servicing or cleaning.

h. For an appliance with a replaceable lamp —

Always unplug before replacing the lamp. Replace the bulb with the same type.

i. For a grounded appliance — Connect to a

properly grounded outlet only. See Grounding Instructions.

INTRODUCTION

The following instructions will provide information for installing Multiplex Beer Conduit with your Beermaster System. Areas which will be covered include routing the conduit for different bar setups, connecting the conduit at the Beermaster Glycol Chiller, connecting the conduit at the beer cooler, and connecting the conduit at the dispensing stations.

FLOOR CHASES

Before pulling beer conduit through a floor chase, ensure the floor chase contains the following:

• 6" (15 cm) minimum PVC conduit chase

• Chase openings should extend 6" (15 cm) above floor

• Wide sweep elbows (2 ft [0.6 m] radius)

• Chase must be clean and dry — no foreign materials

glycol

line**

* To maximize system performance on 6-flavor applications,

Multiplex recommends using a 10 line conduit with 4 glycol lines/2 circuits.

** 2-line “glycol only” conduit, used between chiller and keg

cooler.

Section 2 Installation

Pulling Conduit Through Floor Chase

1. Determine the most convenient way of routing conduit, starting at the end which offers adequate room for installation. The conduit installation process requires the assistance of at least two (2) qualified personnel.

2. Route the steel fish tape through chase opening. Push fish tape through entire chase until it appears at opposite end.

3. Locate an appropriate length of rope and tie to end of fish tape (end which was routed through chase in step 2). Approximately 2 ft (0.6 m) from steel fish tape/rope connection, secure a swab to rope (use mop heads or a bundle of rags for swab).

4. Pull end of fish tape from starting point through chase with rope and swab. The swab will clean any construction materials, moisture, or debris that may exist in floor chase. Continue to swab the chase until the swab exits the chase clean and dry.

5. After floor chase has been cleaned, remove steel fish tape and swab from rope. Locate bundle of beer conduit and unspool conduit to allow unrestricted feed during installation process.

6. Locate rope through floor chase opening and connect to proper end of beer conduit.

NOTE: The beer conduit is designed to be pulled through floor chase in the direction of arrows printed on conduit.

7. After rope has been connected, tap e end of cond uit, including rope, and form conduit end to a point (se e figure above). Tape will ensure that no contaminants enter conduit tubes during installation.

8. Place pointed end of the conduit through chase opening. While one person pushes the conduit through chase, another person should be pulling the conduit through the chase with rope at the opposite end.

9. Once the conduit has been routed through the chase, pull enough conduit through the openings to ensure an adequate supply at each end of the chase for connections.

OVERHEAD INSTALLATION

Refer to the figure above for the following:

1. Determine the correct location for routing the beer conduit. Be sure to avoid heat ducts, hoods, gril ls, or any sharp objects that may exist above drop ceiling tile.

2. Unspool the beer conduit to allow unrestricted feed.

3. Route the conduit above ceiling tiles and connect to ceiling and/or pipes using the appropriate conduit hangers. Be sure the conduit is suspended above ceiling tiles, not lying on the tiles. Care should be taken when determining appropriate method of handing conduit securely. Hanger s must no t cru s h or pinch insulation. This will reduce cooling efficiency.

4. Once the conduit has been routed, ensure an adequate supply of conduit is provided at each end to make all connections.
