Introduction

The following instructions provide the installation proce-

dures required for adding an additional glycol circulating pump

and motor to a Multiplex Model 150, 300, or 450 Beermaster

Glycol Unit.

Note: Unit must be turned “off” during installation.

Caution: To Avoid Serious Injury

Important: Read the following warnings before beginning an

installation. Failure to do so may result in possible death or

serious injury.

DO Adhere to all National and Local Plumbing and Elec-

trical Safety Codes.

DO Turn “off” incoming electrical service switches

when servicing, installing, or repairing equipment.

DO 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.

DO Inspect pressure on Regulators before starting up

equipment.

DO Protect eyes when working around refrigerants.

DO Use caution when handling metal surface edges of

all equipment.

DO Handle CO

2 cylinders and gauges with care. Secure

cylinders properly against abrasion.

DO Store CO

2 cylinder(s) in well ventilated areas.

DO NOT Throw or drop a CO

2 cylinder. Secure the cylinder(s)

in an upright position with a chain.

DO NOT Connect the CO

2 cylinder(s) directly to the product

container. Doing so will result in an explosion caus-

ing possible death or injury. Best to connect the

2 cylinder(s) to a regulator(s).

DO NOT Store CO

2 cylinders in temperature above 125°F

(51.7°C) near furnaces, radiator or sources of heat.

DO NOT Release CO

2 gas from old cylinder.

DO NOT Touch Refrigeration lines inside units, some may

exceed temperatures of 200°F (93.3°C).
