Defrosting the KegMaster™Kegerator
WARN ING
This refrigeration unit DOES NOT automatically defrost
and may require occasional manual defrosting.
DO NOT scrape any ice or frost from the walls or cold plates.
Doing so may damage the unit and void the Warranty!
NOTE: Excessive ice buildup reduces the efficiency of the unit
For tips on how to limit ice and frost buildup please see our Troubleshooting section.
If excess ice or frost has formed on the inside of the KegMaster™Kegerator:
1. Turn the unit off at the mains power
2. Wait an hour or more for the ice to melt.
A hairdryer may be used to speed up the process, by gently blowing warm air at the ice.
3. Wipe any liquid or moisture from the internal walls, floor, and ceiling, using an absorbent cloth or
towel
4. Turn the unit’s power back on.
If excess ice is forming too regularly, see our Troubleshooting tips
Calibrating your KegMaster™Series 4 Kegerator
When to calibrate your KegMaster™Series 4 Kegerator
If your kegerator is freezing the chill plate on the inside with a thick layer or ice, it is
recommended to set the calibration at -3 and see if the situation improves.
If the KegMaster™is not cold enough, it is recommended to set it to +2 and see it the situation
improves.
How to calibrate your KegMaster™Series 4 Kegerator?
1. Press and hold both the “Cooler” and “Warmer” buttons for 5 seconds until the
temperature display flashes SC.
2. Release those buttons and press the “°F/°C” button.
3. The display now shows the calibration factor, and you can change it with the “Cooler” and
“Warmer” buttons.
4. Once it is at the desired value press the “°F/°C” button again to save it.

About Kegs and Kegerators
Kegerators can be used for different keg types and it’s important that you understand what types of kegs
are available and the types of fittings that are required for each type. You will need to customize your
kegerator to suit the kegs that you want to dispense. The keg types can be split up into two main
categories: Commercial and Home Brewing Kegs
Commercial Kegs
Commercial Kegs such as the one on the left are usually used by commercial
breweries and in Australia are mainly sold as 50L kegs. However, smaller sized kegs
do exist, such as 20L, 25L and 30L kegs.
Commercial kegs use several different coupler types as shown below, with the most
common types being the A, D and S-type couplings.
90% of all 50L commercial kegs in Australia will use either A or D-types.
The S-type is most often used for imported beers from Europe or Asia.
The device to connect your beer and gas line to the keg is called a “Keg Coupler”.
Make sure to know what type of keg coupler you need before purchasing the equipment so you can
easily be supplied with the correct one.
A-Type
Also known as the “German Slider”, this type of keg is
used by Toohey, Coopers, West End, Little Creatures,
XXXX and any beer made by Lion Nathan.
To use this keg coupler, just slide the coupling over the
top of the keg and engage the handle on the keg coupler.
This is the most common keg coupler type in Australia
and approximately 45% of kegs in Australia would use
this coupling type.
A-Type Keg
A-Type Coupler
D-Type
Also known as an American Sankey, this type of keg is
used by VB, Carlton Draught, and any beers made by
Carlton United Breweries.
To use the coupler just push the coupler against the top of
the keg, twist clockwise firmly then depress the handle to
tap the keg.
About 40% of kegs in Australia would use this coupling.
D-Type Keg
D-Type Coupler
S-Type
This keg coupler is often confused with the D‐type keg
coupling. It looks very similar however the “well” in the
middle of the coupling is slightly deeper. These kegs are
used by Asian, American, and other imported beers such
as Asahi and Heineken.
To use the coupler just push the coupler against the top of
the keg, twist clockwise firmly then depress the handle to
tap the keg.
About 10% of kegs in Australia use this coupling.

Setting up Commercial Keg Couplers
The gas enters the side of the coupler at about a 30-degree angle and the beer exits the keg coupler out
the top of the keg coupler. For that reason, you will need to connect your gas line from your CO2
regulator to the side of the keg coupler and the beer line from your tap to the top of the keg coupler.
Inside the keg coupler there may be two “one‐way” valves. The one
on the left is the one-way gas valve and the one on the right is the
one-way beer valve. On a kegerator system these valves are not
strictly necessary, and you do not know how to use them it is best to
just take them out of the coupler.
If using barb-tails (pictured right), the keg coupler should include a hex nut, barb-tail,
and rubber washer (as shown to the right).
Always ensure that the rubber washer is between the barb-tail and the coupler body.
Home Brewing Kegs
Home Brewing Kegs, such as those on the left are used by home brewers or small
microbreweries. The sizes are typically 19L or 9.5L.
These kegs have 2 separate posts: one for the gas line (usually marked “IN”), and one for the
beer line (usually marked “OUT”).
The posts are typically either “Ball Lock” or “Pin Lock”. The differences between these two
types are explained as follows.
Ball Lock
Originally used by Pepsi for pre-mix syrups, about 85% of
home brewers use this type of keg because they are easy
to use, have a high availability of spare parts and are
inexpensive.
The 2 posts on the kegs look very similar but are not
compatible. As you can see on the photo to the left the
gas post is slightly different shape to the liquid post. The
gas post has a small ground notch (see arrow) which
signifies the post is a gas post.
Similarly, the ball lock disconnects are also different from
each other.
The grey should only be used for gas and the black
should only be used for liquid.

Disconnects
Pin Lock
Originally used by Coca Cola for pre-mix syrups, about
10% of home brewers use this type of keg.
The 2 posts on the kegs look similar but are not
compatible. As you can see on the photo to the left the
gas post has 2 pins on opposite sides of the post, and the
liquid post has 3 pins equally spaced around the side of
the post.
Similarly, the ball lock disconnects are also different from
each other.
The disconnect with the grey base should only be used
for gas and the disconnect with the black base should
only be used for liquid.
