Glycol Circulating Pump and Motor Kit
P.N. 00211268, 00215866, and 00215948
The following instructions provide the installation procedures required for adding an additional glycol circulating pump
and motor to a Multiplex Model 150, 300, or 450 Beermaster
Glycol Unit.
DO Handle CO2 cylinders and gauges with care. Secure
cylinders properly against abrasion.
DO Store CO2 cylinder(s) in well ventilated areas.
Throw or drop a CO2 cylinder. Secure the cylinder(s)
in an upright position with a chain.
Important: Read the following warnings before beginning an
installation. Failure to do so may result in possible death or
serious injury.
Connect the CO2 cylinder(s) directly to the product
container. Doing so will result in an explosion causing possible death or injury. Best to connect the
CO2 cylinder(s) to a regulator(s).
Store CO2 cylinders in temperature above 125°F
(51.7°C) near furnaces, radiator or sources of heat.
DO Adhere to all National and Local Plumbing and Electrical Safety Codes.
Release CO2 gas from old cylinder.
Touch Refrigeration lines inside units, some may
exceed temperatures of 200°F (93.3°C).
Note: Unit must be turned “off” during installation.
Caution: To Avoid Serious Injury
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.
Notice: 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.
DO Inspect pressure on Regulators before starting up
DO Protect eyes when working around refrigerants.
DO Use caution when handling metal surface edges of
all equipment.

Install the glycol circulating motor with pump to the motor shelf located in the Beermaster Glycol Unit motor compartment (refer to figure 1).
/16"-18 Hex Nut
Carriage Bolts
(Later Units)
Note: Motor must be installed with the glycol pump facing
away from the glycol bath.
Locate the pick up tube and discharge tube assemblies.
Slide one piece of insulation over each of the tube assemblies (refer to figure 2).
Attach the pickup tube to the inlet side of the glycol pump
making sure the opposite end from the pump is submerged
in glycol bath (refer to figure 2).
Attach the discharge tube to the outlet side of the glycol
pump (refer to figure 2).
Slide the 1/2" x 1/2" John Guest Elbow, supplied in kit, onto
the end of the discharge tube at pump motor assembly
(refer to figure 2).
Locate the circulator pump discharge cooling tube, supplied with kit, and insert into water bath area. Insert
straight end of tube into the John Guest elbow fitting as
shown (refer to figure 2).
Insert the two (2) 1/2" OD John Guest bulkhead unions,
supplied in kit, into the pre-punched holes located in the
end of the refrigeration unit (refer to figure 2).
