FINE TUNING YOUR HOT DRAFT® TOWER SYSTEM
If the beverage is not pouring accurately to the setpoint temperature or is pausing during the pour, the Hot Draft® Tower
should be fine-tuned to achieve consistent and accurate pours. Two settings can be manually fine-tuned to improve the
heated pour of the Hot Draft® Tower: Compensation Factor and Flow Rate adjustment. While fine-tuning, monitor your
temperature with an accurate and calibrated thermometer, or by navigating to the IN/OUT screen of the service menu
(see
Service Menu: FLOW, PWM, IN/OUT, & VERSION
in
Navigating your Hot Draft® Tower
on page 9).
Compensation Factor
Fine tuning the Compensation Factor may be required if the exit temperature is slightly inaccurate from the setpoint
temperature. Fine tuning the Compensation Factor will ensure that the unit outputs the correct amount of power to heat
the beverage to the setpoint temperature. To adjust the Compensation Factor, navigate to the COMP screen in the
Service Menu (see
Service Menu: COMP
in
Navigating your Hot Draft® Tower
on page 9). Adjust the Compensation Factor
until the beverage is pouring accurately to the setpoint temperature. For a 208V electrical system, we recommend tuning
the Compensation Factor between 10% - 18%.
Flow Rate
Fine tuning the Flow Rate may be required if the exit temperature is drastically inaccurate from the setpoint temperature.
Fine tuning the Flow Rate will ensure the beverage has optimal contact time with the unit’s heating element.
Begin by
checking the flow rate. Plug in the unit, navigate to “FLOW” in the service menu,
open the hot beverage faucet,
and begin pouring a beverage. The flow rate can be monitored while pouring a beverage. The Flow Rate will be set to
about 0.15 GPM by default. See the table below for recommended flow rates according to your electrical system.

There are 2 methods of adjusting Flow Rate: (1) Adjust pressure at the regulator, and (2) Adjust the Flow Adjustment
Spindle.
1.
One method of adjusting Flow Rate is to adjust pressure at the regulator. A lower pressure at the regulator will
decrease Flow Rate, while a higher pressure at the regulator will increase Flow Rate. Never exceed 60 PSI.
2.
The second method of adjusting Flow Rate is to adjust the Flow Adjustment Spindle (see 7 in
Parts Diagram
on page 7).
To access the flow adjustment spindle, the lid must be removed. ENSURE THE UNIT IS UNPLUGGED AND TURNED OFF
