Komos DraftMaster User manual

Unpack the accessories box located under the top cover. Install the drain plug
on the red rubber tube sticking out the back of the unit. If you will be using
the optional rolling casters, install them now.
Unpack your unit, then unscrew and remove the top cover.
Take a look at the inlet and outlet bulkheads at the front of the unit, noting
the numbered product lines and coolant line located below.
Unscrew and remove the 3-piece reservoir cover.
Attach & clamp tubing from the coolant out bulkhead to the inlet of your
dra tower or trunk line chilling loop.
Fill the reservoir with a 20% propylene
glycol solution – 4 parts RO/distilled/
deionized water to 1 part 99.9%
propylene glycol.
If you choose to use water only – it is
best to use tap water as RO/distilled/
deionized water on its own may
damage the heat exchanger.
Attach & clamp tubing from the outlet of your chilling loop to the coolant
inlet bulkhead.
Check for leaks:
• Plug in the pump and wait for the compressor to cycle on (or lower the
temp setting to force the cycle).
• Look for leaks where the tubing is connected to the cooling system.
• If necessary, tighten and reattach clamps.

INSTRUCTION MANUAL
DRAFTMASTER
Thank you for purchasing
the DraftMaster Glycol
Chiller. The DraftMaster can
be used for the following
applications:
• Use the built-in pump
to cool a trunk line in
a commercial draft
installation.
• Use the built-in pump to
cool a single glycol-ready
draft tower in a home or
commercial installation.
• Using CO2, push beer
through the 4 stainless
coils submerged in the
glycol bath. This allows you
to store kegs warm yet
serve cold beer.
We recommend you use a 20%
glycol/80% water solution in your
bath to eliminate freezing.
ATTENTION

The temperature controller (found just above the red power switch near the bottom of the unit) has several
functions to help maintain ideal conditions to control the temperature of your chilling solution reservoir.
THE CONTROLLER UNIT ITSELF IS
FAIRLY STRAIGHTFORWARD, BUT
IT’S STILL A GOOD IDEA TO GET
FAMILIAR WITH THE BUTTONS/
FUNCTIONS.
THE DESIRED TEMPERATURE SETTING
THE +/- TEMPERATURE RANGE
DraMaster will cycle on/o to keep its
temperature within the set range of the
set temperature - example: if you set the
temperature at 5°C with +/- 0.5 the unit will
cycle on/o over a 1°C range at 4.5°C and
5.5°C. The lowest setting is 0.3°C.
COMPRESSOR DELAY TIME IN MINUTES
This feature protects the unit from turning on/
o too quickly, and potentially damaging the
compressor. The range is from 1-10 minutes
with the default set at 3.
CALIBRATES THE DRAFTMASTER AGAINST
AN ACCURATE THERMOMETER
Generally, the unit does not need any
additional calibration. However, to nd
the correct adjustment - place an accurate
thermometer in the unit and compare against
the controller readout. If needed, set the
calibration on the controller +/- by the number
of degrees it is o. This will ensure the unit is
adjusting to your desired temperature properly.
TO MAKE CHANGES TO ANY
OF THE FUNCTIONS
Hold down the Sbutton until
F1 shows on the controller,
release the button.
Select the desired function by
clicking the UP or DOWN arrows
until the controller shows the
correct function number.
Press & hold the Sbutton while
using the UP/DOWN arrows to
adjust to your desired setting.
Release the Sbutton
And nally, press the POWER
button to lock in the setting.

Check temperature setting by placing a thermometer inside reservoir.
Check aer 30 minutes & compare against set unit temperature.
Calibrate with F4 function on controller as needed.
Check set temperature range. Adjust F2 function on controller
to a higher range.
Ambient room temperature is too high, so unit is working harder
to cool to set temperature.
Humming is normal and gurgling sounds are caused by cooling
liquid used by the unit. The unit may not be not level.
Check circuit breaker or fuse ; Check plugs.

MAintenance/
Cleaning
To ensure the
unit continues to
properly function it
is good practice to
dust/clean the heat
exchangers every 6
months.
