8.5 Start-up checklist
Work steps
1
Read instructions.
2
Check the voltage supply and compare with the values
on the type label.
3
Check the grounding system (by measurment).
4
Check the mechanical connection to the water supply
system. Tighten the flanges and the screws.
5
Fill and ventilate the compact booster unit from the input
side.
6
Check the refilling.
7
Check the switching device to see if all electrical lines
are still securely plugged into the clamps.
8
Check the rotation direction.
9
Check the switch-on and switch-off pressure, correct if
necessary.
11
Venting the pump a second time, after it has been run-
ning for a few minutes (5 to 10).
12
Set the switch to automatic.
13
Check the precharge pressure (refer to Chapter 10.3.1).
14
Secure the shut-off valves of the in and output lines
against being closed
15
Circumstances regarding the system that are not the
same as stated in our documentation or ordering data,
have to be noted in the start-up protocol.
16
Fill out the start-up protocol with the operator and show
the operator how the machine functions.
9. Operation
9.1 Function of operating panel
Refer to instructions of frequency inverter
10. Maintenance
Maintenance should be performed by Honeywell technical staff.
• If necessary contact the service department at Honeywell.
Performance of tasks only by qualified personnel (see section 1.12).
10.1 Safety instructions for maintenance
Danger
Unintentionally switching on the compact booster unit
Danger to life!
The compact booster unit has to be voltage free for all repairs
and maintenance work. Turning off the system with the motor
protection switch does not securely shut off the motor inlet lines.
Only perform maintenance work on the compact booster unit if
you are sure that the compact booster unit is free of power.
Secure the compact booster unit against being switched on
unintentionally.
Danger
Danger of injury from electric voltage.
High shock currents and burns from direct and indirect contact with
live parts.
Turn off the power supply before maintaining the compact
booster unit and secure it from being turned on.
Warning
Components and lines under pressure
Personal and property damage!
Before work is done on pressure-retaining components, the
pump has to be depressurised!
Disconnect the pump from the power supply!

GB
Warning
finished
Inappropriate lifting/moving of heavy modules or components
Personal and property damage!
When moving heavy modules or components, use suitable
transport devices, lifting devices and lifting accessories.
Warning
Unqualified persons working on the compact booster unit
Danger of injury!
Only let specially qualified personnel perfom repair and mainte-
nance work.
Caution
Inappropriately maintained compact booster unit
The proper function of the compact booster unit can no longer be
ensured!
Maintain the compact booster unit regularly.
Set up a maintenance schedule for the compact booster unit
that focuses especially on the pump lubrication, shaft seal and
clutch.
Always observe the safety regualations and instructions.
Observe the instructions for working on the pumps.
In case of damage, please contact our service department.
By setting up a maintenance schedule, the required maintenance to
avoid expensive repairs and achieve fault-free and reliable functioning
of the compact buster unit is held to a minimum.
10.2 Inspection
To ensure that the compact booster unit can be operated reliably, the
required inspections have to be conducted on time.
10.2.1Buffer tank
Caution
Dirt in the system
Damage to the pumps!
Rinse the tank before filling it.
Rinse the tank and the integrated odour trap regularly.
1. Rinse the inlet to the buffer tank if necessary.
2. Rinse the tank and the integrated odour trap regularly.
3. Check if the overflow is sealed and clean.
10.2.2Monitoring Operation
Danger
Filling wrong gas in expansion vessel
Danger of poisoning!
Only fill the pressure pad with nitrogen.
Caution
Dry running causes increased wear
Damage to the pump unit!
Never operate the pump unit when it is empty.
Never close the shut-off valve in the suction line and/or supply
line during operation.
Caution
Exceeding the permissible temperature for the pumped medium
Damage to the pumps!
Operation is not permitted with closed shut-off valves over
longer periods of time (overheating of pump medium).
Observe the temperature values as stated in the data sheet and
under technical data.
During operation observe and check the following points:
1. Check the functional operation.
2. Check switch-on/off pressure when operating the pump and compare to
the values on the type label.
3. Compare the precharge pressure of the membrane pressure vessel to the
recommended values (refer to Chapter 10.3.1).
