4 IMPORTANT - READ BEFORE COMMENCING INSTALLATION
4.1 Water Storage Capacity
The iMatic usable water volume can be found in the technical specification table
(Section 8); the length of time the iMatic delivers water will be dependent on the
usage and refill rates
4.2 Water Temperature
This unit is designed to pump cold water only which should not exceed the
following values:
The maximum allowable water temperature is 23 °C.
The minimum allowable water temperature is 4 °C.
4.3
Pipework - General
Do not drill holes or put fastenings into the iMatic tank, this will cause leakage.
System leaks: Ensure the system to be boosted is able to hold pressure and is leak
free before installing iMatic. Failure to do so will cause abnormal operation and
damage to the unit.
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 iMatic, this will cause damage and possible
leakage.
Flux: Solder joints must be completed and flux residues removed prior to iMatic
installation (flux damage will void any warranty).
Pipework design: Care should be taken in the design of pipework runsto minimize
the risk of air locks e.g. use drawn bends rather than 90o bends.
DO NOT introduce solder flux to flexible hose, tank, pump or any parts
manufactured from plastic.
DO NOT allow contact with oil or cellulose based paints, paintthinners or
strippers, acid based descalents or aggressive cleaning agents.
DO NOT feed other header or gravity tanks with iMatic. It is acceptable to feed
toilet cisterns provided the toilet fill valve operates correctly and is leak free.
4.4 Plumbing Installation Regulations
The plumbing installation must comply with the current water andbuilding
regulations.
The plumbing installation must be installed by a qualified person.
4.5 Pressure Vessel
The iMatic pressure vessel is pre-charged at the factory and must be set correctly
during installation see Section 10 for details.

5 LOCATION - GENERAL
• Access: For emergencies and maintenance the pump must be
easily accessible.
• Protection: The iMatic must be located in a dry, frost free area.
The iMatic must not be installed in a loft space.
• Ventilation: Ensure an adequate air flow to cool the iMatic.
Separate the iMatic from other appliances that generate heat.
• Water retention: Site the unit in a location where in the unlikely
event of a water leak, any spillage is contained or routed to avoid
electrics or areas sensitive to water damage.
• 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 iMatic will run at higher flow rates
before running out of stored water.
• Ambient temperature: The iMatic must be sited in a location
where the ambient temperature does not exceed 30
o
C.
• Pipework: For optimum performance outlet pipework must be 22
mm pipe. Pipework should only reduce to 15 mm when entering
terminal fittings.
• Static outlet pressure: The static outlet head must also be within
the maximum requirement of 15 metres (vertically above the
appliance).
• 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 iMatic if needed.
• Preferred iMatic location: The preferred iMatic location is on a
smooth level floor of sufficient strength to support the filled
weight of the iMatic close to the water source and a suitable
overflow position (see Section 11
- Technical Specification for
filled weight).
The iMatic must not be installed in a loft space.
It must also be considered that the noise and vibration from the
iMatic may be transmitted through the structure the iMatic is
sited on.

7 INSTALLATION & CONNECTIONS
7.1 Mains Water Connection
The iMatic 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 90o elbow 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 iMatic if
needed.
7.2 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 (Figure 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.
7.3 Connection to Overflow/Warning Pipe
The overflow fitting is designed to use G 1 ¼ (35 mm OD) plastic waste pipe.
Ensure there is a demountable joint in the pipe to allow the removal of the iMatic if
needed (Figure 8). The overflow must be free to vent to atmosphere either via a
tundish or a dedicated external pipe.

11
7.4 Unit Location
The iMatic is intended to be installed as a freestanding unit with its back to a wall.
1.
Slide the iMatic into position in front of the services leaving
approximately 20 mm gap between the iMatic and the wall behind.
2. Connect the services using isolation valves and demountable fittings
(push-fit or compression). The positioning of these fittings should allow
the iMatic to be removed without cutting pipes or draining the system.
7.5 Drinking Water Tap
It is recommended that at least one drinking water tap is connected into the un-
pumped mains water supply (typically a kitchen sink), so the water supply is
maintained in the event of a failure of the pumped supply.
