3. Open the water supply and flush the system for 10
minutes.
4. Shut off the water supply, empty the system and
disconnect the drain hose from (EP14-XL2.
5. Close connection (EP14-XL2) using an end cap (not
enclosed) that can withstand a pressure of up to 4
bar.
6. Open the water supply and raise the pressure to 4
bar. Read off the pressure gauge (not enclosed),
which is installed in the water supply system.
7. Shut off the water supply once the pressure reaches
the desired level.
8. Leave the system pressurised for at least 6 hours.
Write a suitable report for the test results.
9. Check carefully for any leakage. If leaks are dis-
covered, these must be repaired. Then follow the
above points again until all leaks have been elimin-
ated.
10. When the heating medium system has passed the
pressure test, empty the heating medium system
and remove all connected hoses.
Caution
Use suitable drainage systems according
to local legislation to empty the pipe sys-
tem.
Connections, heating medium: 2-12, 2-16, 3-16

Cleaning and filling
Filling and venting the brine system
Caution
Because the temperature of the brine system
varies depending on the heat source, the 5.1.7
“br pmp al set.” menu must be set to a suitable
value.
1. Use filling pump LK Pumpmobil FSB 30, or equivalent,
in this procedure.

2. When filling the brine system, mix the water with
antifreeze in the filling pump’s mixing vessel (2). The
mixture should have freezing protection down to
approx. -15°C.
3. Place the filling pump in a convenient location in the
vicinity of the GreenMaster-HP to optimise user-
friendliness.
4. Connect the power supply.
5. Connect hose (3) to filler connection (XL27).
6. Connect hose (1) to filler connection (XL28).
7. Ensure that shut-off valve (QM34) is in the closed
position, in the right-hand position.
8. Open the valves for the filler connections (XL27) and
(XL28).
9. Start the filling pump by pressing the filling pump’s
(4) start button.
10. Vent the system by performing the activities in step
6-8 in chapter Flushing with water and cleaning,
page 31.
