7.11 Standby indicator
The system standby mode has to be registered by the operator or their
contractors at the responsible authority (most commonly WVU or factory
inspectorate). Before starting the system, the author has to certify that the
prerequisites for connection are fulfilled.
Before the system is connected to the mains power supply, the operator has
to read the relevant VDE regulations.
The electrical supply lines must only be installed by companies that are
authorised to do such work.
8. Start-up
Performance of tasks only by qualified personnel (see section 1.11).
8.1
Safety instructions for start-up
Warning
Danger from improper operation.
Malfunctions
Before starting, the manual has to be read by the operator as
well as by the responsible technical/operating personnel and
has to be stored at the site of the compact booster unit at all
times.
Adhere to local safety and accident regulations when starting
the compact booster unit.
Damaged or improperly installed compact booster unit.
Malfunctions
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!
If water shortage occurs during start-up, in manual or testing
mode, the compact booster unit shuts off after approx. 10s. If
the dry running protection is deactivated, then the operator
takes responsibility in the case of dry running.
The responsible authorities have to be informed before start-up and be-
fore 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 Honeywell 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 the pressure switch due
to the lack of pressure on the output side. This is not even
prevented if the motor protection switch is also activated.
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.
The protection against dry running is only active in manual and testing
modes.
1. Connect electrical circuit on-site.
2. Main switch set to 0 and manual/automatic switch to automatic.
3. Connect water supply for refilling on-site.
4. Open or loosen the ventilation screws on the pump (refer to operating/
assembly instructions).
5. Slowly open the shut-off valves on the input side and fill the system until
pump medium runs out of every ventilation borehole.
- To do so, loosen the setting screw to open the refilling valve and fill the
tank after connecting the system to the water supply.
- Set the amount of refilling water with the throttle valve. (refer to
Chapter8.3.1.2).
6. Close the ventilation screws, tighten pump ventilation lightly.
7. Set main switch to I.
8. Set system with manual/automatic switch to manual operation and
check in which direction the pump is rotating.
- 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.
9. Set system with manual/automatic switch to automatic operation.
10. 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.).
- If the switch-on pressure is set to the wrong value, it has to be changed
as described in the pressure switch manual.
11.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-off pressure is set to the wrong value, it has to be changed
as described in the instructions of the pressure switch.
- The follow-up time has to be set on the relay to the maximum number of
operating cycles that are permissible for the motor by turning the setting
screw until it reaches a value between 3 and 10 minutes. Up to 7.5kW =
20 cycles/hour, from 11 to 22kW = 10 cycles /ho, from 30kW = 6 cycles/
hour)
12.Let the pump run again with the output shut-off valve open, loosen the
ventilation screw and let the rest of the air out.
13.Close the ventilation screw tightly.
14.Check if the pump runs smoothly.
15.By closing the shut-off valve on the output line, check if the pump
reaches its maximum pumping head in the zero point.
