Initial Operation - resideo Braukmann CBU146 Einbauanleitung

 Check the compact booster unit for obvious signs of
damage; eliminate any defects immediately or alert
the supervising personnel. The compact booster unit
may only be operated in perfect working order.
Inform yourself sufficiently about
• the equipment of the compact booster unit
• the functionality of the compact booster unit
• the close surroundings of the compact booster unit
• the measures to be taken in an emergency
8.2 Start-up requirements
CAUTION!
Dry running pump
Damage to the pump/system!
Ensure that there is no water shortage.

The responsible authorities have to be informed
before start-up and before testing.
Before start-up of the compact booster unit, the following
points have to be ensured:
• The compact booster unit has to be connected to all
protective equipment according to the regulations.
• The relevant VDE and country-specific regulations
have to be adhered to and fulfilled.
• The buffer tank has to be full of water.
• The refilling has to function properly.
• Flange connections have to be checked if they are
fastened tightly.
• Pipe fittings between pump and pipeline have to be
tightened.
• In and output openings for air-cooling of the motor are
free.
• The precharge pressure of the membrane pressure
vessel is checked.
• All shut-off valves in the system are open.

8.3 Initial operation

The initial start-up should be performed by Resideo technical
staff.
CAUTION!
The pipeline is not free of residue
Danger of damaging the pump/compact booster unit!
Before start-up (and testing) make sure that pipelines

and compact booster unit are free of residues.
CAUTION!
No pressure on the output side
Pump starts when main switch is turned on!
During start-up and also during automatic mode, the

pump starts as soon as the main switch is turned on,
because the system receives a start command from
MU1H-1376GE23 R0320
GB
the pressure sensor due to the lack of pressure on the
output side. This is not even prevented if the motor
protection switch is also activated.
In case of water shortage the system does not start.
The start-up, or testing mode, of the compact booster
unit may only be initiated if all VDE regulations have
been fulfilled.
Floating ring seals may briefly show signs of leakage
during start-up, but no longer after a short period of
operation.
1. Connect electrical circuit on-site.
2. Connect water supply for refilling on-site.
3. Open or loosen the ventilation screws on the pump
(refer to operating/ assembly instructions).
4. Slowly open the shut-off valves on the input side and
fill the system until pump medium runs out of every
ventilation borehole.
5. Close the ventilation screws, tighten pump ventilation
lightly.
6. Set main switch to I.
7. Check direction of pump rotation.
• The direction of rotation has to be the same as the
direction shown by the arrow on the motor. If it is
rotating in the wrong direction, two phases of the
inlet have to be exchanged.
8. Slowly open the shut-off valve of the output and use
the pressure guage to check if the system starts if the
switch-on pressure is reached (refer to Chapter 5
Technical Data).
• If the switch-on pressure is set to the wrong value,
it has to be changed as described in the frequncy
inverter manual.
9. Slowly close the shut-off valve of the output and use
the pressure guage to check if the system shuts off
when the switch-off pressure is reached (refer to
Chapter 5 ).
• If the switch-on pressure is set to the wrong value,
it has to be changed as described in the frequncy
inverter manual.
10. Let the pump run again with the output shut-off valve
open, loosen the ventilation screw and let the rest of
the air out.
11. Close the ventilation screw tightly.
12. Check if the pump runs smoothly.
13. By closing the shut-off valve on the output line, check
if the pump reaches its maximum pumping head in the
zero point.
