Bleeding the booster pump
The pump housing must be filled with water before starting the booster pump for
the first time. Once the break tank has been filled with water, the booster pump is
bled by slackening the bleed screw on the top right-hand side of the pump
housing. This may be accessed via the plastic plug on the right-hand side of the
machine. The booster pump is located on the removable booster heater kit.
