Fill the reservoir until the copper cooling coils are completely submerged. If filling with water only, set the reservoir to
1.6°C (35°F). If using a water/glycol solution, see the chart below for a quick reference of freezing points based on the
concentration of water to glycol. Please note that the reservoir temp should never be set below -2.2°C (28°F), or you
may risk freezing the beer sitting your product lines between pours. The amount of glycol required to be added to the
reservoir depends on the desired set temperature of the reservoir which is dependent on a number of factors including
heat ingress into the entire system, insulation of the glycol lines, ambient temperature, the number of kegs being
cooled and the temperature of the kegs. Use the table below to determine what percentage of glycol you require.

You can measure the glycol percentage using a calibrated refractometer and comparing to the specific gravity at 32°F
in the above table.
We would advise running a 20% glycol solution, as this will be sufficient to lower the reservoir temp to the lowest
recommended setting of -2.2°C (28°F), and will give you some runway to top up the reservoir using only distilled
water when needed.
DISPENSING BEVERAGES
Use the diagrams on the following pages determine how to dispense beverages.
PLEASE NOTE that the diagrams
are for demonstration purposes only. You may have a different style coupler or tap and shank setup to what is shown
in the below diagrams. Fittings other than Duotight fittings can be screwed onto the 5/8" BSP shanks for the product
lines such as:
• Liquid Ball Lock Post with 5/8" Thread (
D1745
)
• K-lok female to 5/8" Female (
D1931
)
• Duotight Female Beer Thread adapter 8mm (
DUO117
)
• Tailpiece Hex Nut (
D1740
) and any of the below barbs:
• Elbow Tailpiece 1/4" (
D1721
)
• Straight Tailpiece 1/4" (
D1725
)
• Straight Tailpiece 3/8" (
D1735
)
• Straight Tailpiece 5/16" (
D1730
