STEP 7
Fill and ventilate the pressure maintenance pumps and
the piping.
• The shut off devices at the intake side of the pump(s) (1)
must be opened completely (ex factory)
• Remove the plug at the filler hole/use the de-aeration
possibility in the plug (2)

Figure: pump filling and ventilation
• If a EMCF-1 V makeup module is installed, go to manual
mode (user level 3), see chapter 5.7, "user level 3".
• Switch on the output "makeup valve Y1" ("output: on")
and fill the vessel until a continuous water jet leaks from
the filler hole at the pressure maintenance pump. After
this set the output "makeup valve Y1" to automatic mode
("output: auto"). The pump should be filled at a level
(reference value) of ca. 30 - 40%. During this filling the
vessel level can be watched at the main display.
• If a makeup module is not installed, you have do fill the
system until the vessel is filled via the overflow valve
and a continuous water jet leaks from the filler hole of
the pressure maintenance pump. If the system pressure
rises too high, you could reduce the set upper working
pressure at the overflow valve (see fig. 11).
• To ensure a complete ventilation, start and stop the
pump in manual mode ("output: Test", operate with "F1")
several times.
• Reassemble the plug of the pumps filler hole.
• AT devices with two pressure maintenance pumps
(systems PHP)‚ repeat the above steps for the second
pump (pump 1 = left side, pump 2 = right side)
• Open the emptying right beside the overflow valve and
ventilate the piping completely by starting and stopping
the pump(s) in manual mode several times. After this, shut
the emptying.
INFORMATION
Tip: Shut off all expansion vessels except the first main
vessel previously to accelerate the filling.
