7 MAINTENANCE

7.11 Pressure vessel: The pressure vessel should be checked once every
12 months to have its pre-charge checked or replenished, this should be
carried out as follows:-
a) Isolate pump electrically.
b) Remove the front cover.
c) Isolate the water supply by closing the appropriate isolating valves.
d) Release system water pressure by opening an outlet on the system.
e) Check pre-charge at Schrader valve (Fig. 17) using a tyre pressure gauge.
f) Replenish pre-charge by injecting air into the vessel via the Schrader valve
using a car or bicycle pump (Fig. 17).
g) Close all system outlets, open inlet and outlet isolating valves.
h) After maintenance is completed refer to Section 6 – Commissioning for
instructions on re-starting pump.

7.12 Water scale: In areas of hard water, scale can cause the mechanical pump seal
to stick if left without use for long periods. The pump must be run for at least
5 minutes every four weeks to "exercise" all working parts. See Section 8 –
Technical Specification for note on water temperature.
7.13 Water quality: The iBoost has been manufactured to the highest standard
from WRAS approved materials.
As with any stored volume of water; in order to ensure that the water remains
fit for use the water temperature needs to remain below 20
quality of stored water will deteriorate with time and temperature. Bacterial
growth is dependent on the water temperature, growth rates will be higher
when the conditions are warm.
If the water remains unused for long periods of time, the tank should be
drained and flushed through. The tank should be cleaned on an annual basis
to protect against bacterial growth. The system must be maintained in line
with current Health & Safety regulations.
Model
iBoost F200
iBoost V200 The pressure vessel pre-charge
must be set to 90% of the
pump set pressure. I.e. If pump
pressure is set to 3 bar, then the
pre-charge value should be 3 x
0.9 = 2.7 bar (39 psi).
