1 IMPORTANT FACTS: READ BEFORE COMMENCING PUMP INSTALLATION
A Water storage capacity.
1.11 The iBoost has a usable water volume of approximately 200 litres; the length
of time the iBoost delivers water will be dependent on the usage and refill
rates.
1.12 Ensure the pump is primed as described in the priming section before
starting, to avoid causing damage to the pump shaft seal. See Section 6 –
Commissioning.
B Water temperature
This unit is designed to pump cold water only which should not exceed the
following values:
1.13 The maximum allowable water temperature is 23 oC (see Section 7.13).
1.14 The minimum allowable water temperature is 4 oC.
C Pipework – General
1.15 Do not drill holes or put fastenings into the iBoost tank, this will cause
leakage.
1.16 System leaks: Ensure the system to be boosted is able to hold pressure and
is leak free before installing iBoost. Failure to do so will cause abnormal
operation and damage to the unit.
1.17 Secure pipework: Ensure pipework to and from pump is independently
supported & clipped to prevent forces being transferred to inlet and outlet
branches of pump. Do not secure pipework to the iBoost, this will cause
damage and possible leakage.
1.18 Flux: Solder joints must be completed and flux residues removed prior to
iBoost installation (flux damage will void any warranty).
1.19 Pipework design: Care should be taken in the design of pipework runs to
minimize the risk of air locks e.g. use drawn bends rather than 90obends.
1.20 DO NOT introduce solder flux to flexible hose, tank, pump or any parts
manufactured from plastic.
1.21 DO NOT allow contact with oil or cellulose based paints, paint thinners
or strippers, acid based descalents or aggressive cleaning agents.
1.22 DO NOT bend the flexible hose beyond 30o. It must be installed as
straight as possible.
1.23 DO NOT feed other header or gravity tanks with iBoost. It is
acceptable to feed toilet cisterns provided the toilet fill valve operates
correctly and is leak free.
D Plumbing Installation Regulations
1.24 The plumbing installation must comply with the current water and building
regulations.
1.25 The plumbing installation must be installed by a qualified person.
E Pressure vessel
1.26 The iBoost F200 Pressure vessel is charged at the factory see Section 7 –
Maintenance for details.
1.27 The iBoost V200 pressure vessel pre-charge must be set correctly during
installation, see section 6.12 for details.

2 LOCATION  GENERAL
2.11 Access: For emergencies and maintenance the pump must be
easily accessible.
2.12 Protection: The iBoost must be located in a dry, frost free area. The
iBoost must not be installed in a loft space.
2.13 Ventilation: Ensure an adequate air flow to cool the iBoost.
Separate the iBoost from other appliances that generate heat. Do
not block the vent holes on the front panel.
2.14 Safety: Motor is not accessable in normal operating mode. Unit
must only be operated with the front cover in place.
2.15 Water retention: Site the iBoost in a location where in the unlikely
event of overflow, water leak, any spillage is contained or routed to
avoid electrics or areas sensitive to water damage.
The iBoost has a weir type overflow at the rear of the tank, in the
event of overflow, the water will drain from the weir area.
A minimum gap of 50 mm must be allowed at the rear of the tank to
allow any possible overflow water to exit the weir area. The weir
area must not be blocked or covered.
2.16 Supply inlet pressure: The water supply inlet pressure must be lower than
7 bar; lower supply inlet pressures will reduce the tank fill rate and reduce the
time the iBoost will run at higher flow rates before running out of stored water.
2.17 Ambient temperature: The iBoost must be sited in a location where the
ambient temperature does not exceed 30 oC (see Section 7.13 – Water
Quality).
2.18 Pipework: For optimum performance outlet pipework must be 22 mm pipe.
Pipework should only reduce to 15 mm when entering terminal fittings.
2.19 Static outlet pressure: The static outlet head must also be within the
maximum requirement of 15 metres (vertically above the appliance).
2.20 Noise: A flexible hose is supplied as standard which will minimise the
transmission of noise and vibration from the iBoost pump to the pipework
connected to the appliance outlet. However, care must be taken when
mounting the iBoost that any noise is not amplified through loose panels or
pipework.
2.21 Direction of flow: Ensure the water flow is in the direction of the arrow
marked on the flow switch reed clamp (vertically upwards).
2.22 Flexible hose: Only use the Stuart Turner hose supplied with the pump.
2.23 Isolating valves: Separate system isolating valves (non restrictive) must be
fitted to allow easy pump service. Isolating valves must be mounted where
specified to allow the system isolation and removal of the iBoost if needed.
See Section 4 for installation details.
2.24 Preferred iBoost location: The preferred iBoost location is on a smooth level
floor of sufficient strength to support the filled weight of the iBoost close to
the water source and a suitable overflow position (see Section 8 – Technical
Specification for filled weight).
The iBoost must not be installed in a loft space.
It must also be considered that the noise and vibration from the iBoost may
be transmitted through the structure the iBoost is sited on.
Ensure there is sufficient room above the iBoost to allow the removal and
servicing of the internal float valve if needed, typically 350 mm.

4 INSTALLATION & PUMP CONNECTIONS
4.11 Mains water connection to iBoost 200 CAT 5: The iBoost is to be
permanently connected to the mains water supply using rigid pipe or
suitably sized and rated flexible hose to comply with current building and
plumbing regulations.
The water tank fill valve has a G ½ male threaded fitting; a suitable 90oelbow
type fitting must be used. When tightening ensure the fill valve within the
tank is not rotated. If the valve is rotated it may not function correctly with
the risk of flooding.
Ensure there is a demountable joint in the pipe to allow the removal of the
iBoost if needed (see Fig. 8).
4.12 Water outlet pipework:
1. The pump has a G ¾ threaded connection to accept the supplied hose.
The hose is made water tight with a sealing washer on assembly, nip
tight to 4 to 5 Nm for water tight seal. (Do not overtighten). The supplied
hose must only be connected to 22 mm pipework.
Ensure the pipe is free from all score marks and deformities in the area of
the insertion depth (Fig. 4) and cut the pipe square removing all burrs and
sharp edges to prevent damage to the sealing ‘O’-ring.
2. Prior to inserting the pipe into the fitting mark the insertion depth on the
wall of the pipe with a soft pencil at a distance of 33 mm from the end to
be inserted.
3. Check in the mouth of the fitting that the ‘O’-ring, nylon washer and collet
are in position.

4. Push pipe firmly into fitting, until pencil mark is level with the top of the
collet and the pipe stop resistance is felt. Pull on the pipe to check it is
secure and correctly fitted.
5. To break the joint, push pipe firmly into fitting, hold collet down and
gently remove pipe. If the system has been fitted with water care should
be taken to isolate pump and towels used to absorb spilled water.
4.13 Connection to warning pipe: The overflow fitting is designed to use
G ¾ (21.5 mm OD) plastic waste pipe. Ensure there is a demountable joint in
the pipe to allow the removal of the iBoost if needed (see Fig. 8). The
warning pipe must be free to vent to atmosphere either via a tundish or a
dedicated external pipe.
4.14 The iBoost is intended to be either installed as a freestanding unit with its
back to a wall (minimum gap 50 mm) or into a 600 mm wide, 2 m high
cupboard. If installed into a 600 mm cupboard the floor and back panel will
need to be removed and the cupboard spaced forward to allow the 50 mm
clearance at the rear to allow for the weir overflow discharge. The carcass of
the cupboard will need to be screwed to the adjacent units and the wall for
support (also see section 2.15).
All the services are connected to the iBoost via a plumbing access window at
the back of the unit, the installation is conducted in 4 simple steps.
Prior to installation remove the screw on the top of the unit and pull the
corner of the front cover to remove it and retain them in a safe place.
Step 1
Position the paper installation template on the wall where the iBoost is to be
installed, ensuring the ‘floor level’ of the template is level and resting on the

pressurise the system then stop.
b) Open and close all outlets in turn associated with the pump, (including
w/c systems) allowing water to flow from each outlet until all air is
purged. As each outlet is opened and closed, the pump will start and stop
respectively.
Note: After closing the outlet there will be a small time delay before the
pump stops, which is normal.
c) Any tap or control valve within the system when opened and closed will
now turn the iBoost on/off, there will be a delayed start due to the water
stored in the pressure vessel. Providing this is the case the system is now
operating correctly.
d) Carefully check pump and pipework for leaks whilst pump running and
stationary before leaving the installation unattended.

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 oC. The
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.

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).
