60l BREWING SYSTEM

Read all the instructions carefully & keep this
manual for future reference.
Never submerge the brewing vessel. To clean
the exterior, use a damp cloth. Always protect
the electric power cable from water.
Do not switch on the machine if the vessel is
empty. The machine does have a dry-boil cut-
off switch to turn the element off if it overheats
(when there is no water) but the element &
electronics may still be damaged. The warranty
does not cover damage due to dry-boil.
Do not use this device if the cord or plug is
damaged.
Switch off the brewing vessel correctly before
removing the plug.
Only move the brewing vessel when the power
is shut off & it is empty (no water inside the
unit).
Do not turn the pump on for more than 5 min-
utes at a time during wort boiling (bubbles will
cause the pump to idle & wear out under high
temperature). It is not recommended to use the
pump for pumping out the wort aer cooling
(rather use the tap on the front of the unit).
Hops & trub may enter the pump, potentially
blocking & damaging the system.

Valve Operation:
This valve is to open and close the wort circulation from the
pump. It is also used to adjust the wort ow during mashing.
Tap Operation:
To OPEN, pull the safety latch upwards and turn the
lever 90° counterclockwise. To CLOSE, pull the safety
latch up and turn the lever clockwise by 90°.
Circulation tube assembly:
Adjust the ow rate using the blue valve. If the ow is too fast, the grain basket will overow down the central pipe, and the bottom
of the boiler may run dry. Adjust the ow until the ow from the pump matches the speed at which the wort ows through the grain.
This may need to be adjusted during the mash.

Operating Instructions

Valve Operation:
Grain basket overow assembly:
Secure the overow pipe into the bottom sparge plate by inserting
the larger, threaded end of the overow pipe through the hole in the
bottom plate and securing the nut from the bottom. Make sure that the
nut is only nger tight. Then attach the smaller nut on the top of the over-
ow pipe.
The white grain stopper cap is only used while mashing in so that the milled grain
cannot fall into the overow pipe. Remove this cap when all grains have been added.

LET’S GET BREWING!
Feel free to contact one of our
experienced brewmasters for advice &
suggestions as well as exciting brewing
recipes in various beer styles. We also offer a
wide range of ingredients that work perfectly
for the Dema-Cra 60l. Visit our website at
www.dematechsa.com or reach out at info@
dematechsa.com. Follow the brewing process
example on this page for your convenience.
Make sure that the brewing vessel is positioned on a stable and secure surface before
brewing as a full vessel contains boiling hot liquids and can weigh up to 70kg
12
• Always clean the brewing vessel before and aer use.
• Attach the Bazooka lter to the inside tail of the tap using the
included hose clamp.
• Add the required quantity of strike water before switching the
brewing vessel on.
• Insert the bottom sparge plate into the malt pipe and then insert
the malt pipe into the brewing vessel.
• Heat up the water to your strike temperature in either manual or
auto mode.
• Add the milled grain into grain basket and stir it gently.
• Once your grain is well mixed and completely saturated, gently
place the top sparge plate on top of your mash.
• Switch on the pump to circulate the wort through your grain bed.
If the wort is over owing through the central overow pipe,
reduce the pump ow by using the blue valve.
• Aer mashing, carefully li the malt pipe with the included
handle, and gently set the feet of the malt pipe down onto the
support ring on the boiler.
• If you are sparging, you can gently pour your sparge water into
the malt pipe and let it run through your grain. Leave the grain
to drain into boiler for at least 10mins aer sparging before
removing.
• Heat up the wort to boiling temperature.
• Add the hops etc. at the correct times according to your recipe.
• Immerse your wort chiller into the boiling wort 10 minutes
before the end of the boil to sanitise it.
• Aer the boil is nished, cool down the wort to the pitching
temperature stated in your recipe before transferring to your
fermenting vessel via the tap and bazooka lter on the front of
the machine.

Follow this maintenance guide:
13
• Place 10-20L of water into the machine and heat to 60C. Dissolve
a brewing cleaner such as DemaClean into the warm water and
recirculate it through the pump for 15 minutes while you clean
the inside of your Demacra with a so cloth.
• Do not use sharp metal implements to remove any residue. Use a
so cloth or so scouring pad to clean the inside of the boiler.
• Any wort residue on the base of the boiler should be cleaned off
before next use.
• Aer cleaning rinse the machine well, including ushing the
pump by connecting a hose to the pump outlet.
• Do not get water on any electronic parts of the machine.
• Do not immerse the machine in water.
• To clean the outside of the brewing vessel, simply use a damp,
so cloth.

Ingredients stuck in the pump
C1-- temperature offset
ERR-1 shown on display
Failing to reach 100
C2-- boiling point offset
ERR-2 shown on display
Flush the pump by connecting a hose to the outlet of the pump.
If that fails, dismantle the pump to remove the ingredients
Put the lid on to see if it comes to a boil. If that fails, do a tem-
perature correction as described below
Press “-” and “+” at the same time enter into the C1 tempera-
ture correction setting. Setting range is from -10 to +10. This
is a temperature offset if the probe is reading the temperature
incorrectly
Press “-” and “+” at the same time enter into the C1 tempera-
ture corrected setting and then press the AUTO/PAUSE button
to enter into the C2 temperature correction setting. This is a
temperature offset for the boiling
This error is displayed if the temperature reading is lower than
-20 °C. This is most oen due to a loose probe connection. To
rectify, open the bottom of the machine and check if the sensor
is loose
This error is displayed if the temperature reading is higher than
120 °C, it is an overheat/boil-dry warning temperature only
