Commissioning/decommissioning
To guarantee maximum operational reliability at the lowest
possible operating cost, we recommend inspecting and
maintaining the Wilo-WiBooster regularly. It is advisable to
have a maintenance agreement with a specialist company
or with our after-sales service department. The following
inspections should be made regularly:
• Check that the Wilo-WiBooster is ready to operate.
• Check the mechanical seal of the pump. The mechanical
seal needs water for lubrication and small quantities
of it can leak out of the seal. If the volume increases,
change the mechanical seal.
Check the
diaphragm pressure vessel
(every 3 months is
recommended) to make sure that the
supply pressure
is
set correctly, please refer to the diaphragm pressure vessel
recommended charge section in this document for guidance
(Section 6.2.5.1).
CAUTION! Risk of damage!
The function of the diaphragm vessel is compromised and
can lead to system faults.
Set the tank pressure to the correct level. Isolate (see step 1
of figure 5d) the pumps and system from the discharge side
and upstream piping of the manifold. Drain the water from
the discharge manifold. Check the gas pressure at the valve
(see step 2 figure 5d) of the diaphragm pressure vessel. Use
an air pressure gauge and correct the pressure as required.
To assure proper air flow to the control panel, inlet
and outlet air filters for the panel fan must be cleaned
periodically. If the system is out of service for a long period
drain all the pumps by opening the drainage plug on the
bottom of the pump base.

Faults, causes and remedies
Faults, particularly those affecting the pumps or control
system, should only be remedied by Wilo USA’s after-sales
service or a specialist company.
NOTE!
The general safety instructions must be observed when
doing any maintenance or repair work. Also reference the
Installation and Operating Instructions for the Scot Pump.

Spare parts
Spare parts or repairs may be ordered from local service
