8. Start-up
8.1 Safety instructions for start-up
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
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.
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
water 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 gauge
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 chapter 8.3.1.
9. Slowly close the shut-off valve of the output and use the pressure gauge
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 chapter 8.3.1.
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.
8.3.1 Change switch-on pressure
1. Click on the settings key indicated by as spanner symbol
2. Move up and down using the arrow keys to setting value 1-2-3-3
3. Press OK key
4. Move up and down using the arrow keys to desired setting value for the
discharge pressure in bars.
5. Press OK key confirm the set value
6. For any further information please Refer to instructions of frequency
inverter
8.4 Switching the system on
1. Secure the shut-off valves of the in and output against being closed.
2. Operate the main switch to supply the system with voltage.
- The green LED indicates that the unit is ready to use.
Performance of tasks only by qualified personnel (see section 1.12).
Warning
Danger from improper operation.
ª
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.
ª
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.
Caution
Dry running pump
ª
Damage to the pump/system!
Ensure that there is no water shortage.
The responsible authorities have to be informed before start-up and be-
fore testing.
Caution
The pipeline must be free of residue
ª
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
ª
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 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.
