 Parts / Components

Main Cooler

This is the refrigerator part of the Keg Cooler. It is a small refrigerator with holes to
allow for the hoses and beer tower. There is a thermostat dial inside the front of the unit at the
top left that controls the temperature in the unit. The ‘cold’ is generated from a cold plate in the
rear of the unit.

Castors

Elevate the unit

Allow unit to be easily moved

Can be locked for stability

Necessary for door to work properly.

Front castors use metal washers to

distribute weight

Rear Castors screw to metal frame of

the unit

Attached Front Caster w/ Washer

Interior

The inside of the refrigerator

Where the Keg goes

Has metal plate at bottom to hold kegs weight

Thermostat is accessed inside

Cooler w/ Keg of
Bud in it

Thermostat Control

Hole for Red Air Hose

Rear Cooling Plate

Metal Plate to put keg on

2

Thermostat

The thermostat, located in the front, top left corner inside the refrigerator, is used for
controlling the internal temperature of the unit.

Dial is numbered 1-6, and off. The

higher the number, the colder the
temperature

Can be used to turn unit off

Also called the ‘cold control’

Close up of the thermostat
removed from it’s housing.
*Note the adjustment screw
that will change the range it
cools.

Rear

Simply put, the back of the Keg
Cooler. For the most part, once the unit is
assembled and running, the back is out of
site. Would mostly be accessed only to
check pressure on the regulator, turn CO2
on or off, or to refill the CO2 cylinder.

Compressor is in the back

CO2 Cylinder and Regulator are

in the back

Serial # and spec sheet located

on back

Has hole for Red Air Hose to

pass through

Also in view is the hole to allow the air hose to
pass to interior of unit.

These knobs are what the CO2 cylinder
bracket attach to.

cylinder bracket, CO2 cylinder,
regulator, and air hose.

CO2 Cylinder

Metal air canister designed to hold compressed air

Has brass valve that regulator connects to

Black On/Off handle to start/stop flow of air

Does NOT come full, must be filled prior to use

Sits in cylinder bracket, which attaches to the rear

of the unit

Valve must be opened ALL the way for proper

operation of the unit

cylinder bracket (right)

Regulator (Single or Double Gauge)

The regulator controls, or ‘Regulates’ the air flow coming from the CO2 cylinder. It
consists of a brass fitting that attaches it via hex nut to the cylinder. This nut must be firmly
seated, and tightened with a wrench. There is a rubber washer built in to the connection to
prevent leaks. There are 2 types of regulator, single and double gauge. The regulator also has a
secondary shut off valve, which can shut off air flow going to the keg, while still allowing air
from the cylinder to the regulator.

Gauges indicate air pressure in p.s.i. (lbs. per square inch)

Single gauge regulator shows pressure leaving the regulator

Double gauge shows air pressure leaving regulator, and air pressure in the CO2

cylinder

Secondary cut off valve stops air flow from regulator to the keg

Secondary cut off valve must be all the way open for proper operation

Flathead screw sticking out the front used to adjust pressure to the keg

Left – Single Gauge Regulator

Right – Double Gauge Regulator

5

Air pressure in the
CO2 cylinder
(double gauge only)

Attaches to Red Air
Hose. Air flows from
here to coupler.

Air pressure to Coupler
(Keg). Typically
between 10-14 p.s.i.

Screw used to adjust the
pressure to the Keg.

Attaches to CO2
cylinder. Air comes
in to regulator.

Above: Another type of secondary cut off,
again in the “Off” or “Closed” position.
You can faintly see an upside down “C”
and an “O” at the rounded end of the lever
indicating the position.

Below: One type of secondary cut off
valve in the “OFF” or “Closed”
position. In this position, no air is
flowing to the coupler. The lever
would be down for the “ON” or “Open”
setting. Open allows air to flow to the
coupler.

Red Air Hose

The red air hose is the red tube the runs between the bottom of the regulator (under the
secondary cut off valve) and the coupler

5/16” Inner Diameter and 9/16”

Outer Diameter

Hose is 5’ long

Attaches to bottom of regulator with

hose clamp

Runs from regulator through hole in

back of cooler to the interior

Attaches to coupler with hex nut

Below: Barbed connector where Red Hose
connects to Coupler. Hex nut holds and secures
connector in place

Above: Red Hose and barbed connector
assembled, ready to attach to coupler via
the hex nut. Notice washer, which goes
into this connection.

to interior of unit.
