1 IMPORTANT FACTS: READ BEFORE COMMENCING PUMP INSTALLATION
A Water storage capacity.
1.11 The Matrix Mini has a usable water volume of approximately 2 litres; the length of time
the Matrix Mini takes to pressurise a system will be dependent on:-
The pressure differential between the cold fill and set pressures and also the refill rate of
the tank
1.12 Ensure the pumps are primed as described in the priming section before starting, to
avoid causing damage to the pump. See Section 6.20 Hydraulic 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 10).
1.14 The minimum allowable water temperature is 4 oC.
C Pipework - General
1.15 Do not drill holes or put fastenings into the Matrix Mini tank, this will cause leakage.
1.16 Secure pipework: Ensure pipework to and from pump is independently supported &
clipped to prevent forces being transferred to inlet and outlet branches of the unit. Do
not secure pipework to the Matrix Mini, this will cause damage and possible leakage.
1.17 Flux: Solder joints must be completed and flux residues removed prior to Matrix Mini
installation (flux damage will void any warranty).
1.18 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.
1.19 DO NOT introduce solder flux to flexible hose, tank, pump or any parts
manufactured from plastic.
1.20 DO NOT allow contact with oil or cellulose based paints, paint thinners or
strippers, acid based descalents or aggressive cleaning agents.
1.21 DO NOT bend the flexible hose beyond 90o. It must be installed as detailed,
DO NOT kink. See Installation Section 4.14.
D Plumbing Installation Regulations
1.22 The plumbing installation must comply with the current water and building regulations.
1.23 The plumbing installation must be installed by a qualified person.
E System Filling
1.24 The Matrix Mini is NOT DESIGNED TO FILL THE SYSTEM FROM EMPTY. It is only
intended to top up the system after occassional water leakage. Systems should be filled
via a dedicated filling loop.

2 LOCATION-GENERAL
2.11 Location: The Matrix Mini must be located on a solid wall of sufficient
strength to support the filled weight of the Matrix Mini, close to the water
source and a suitable overflow position (see Section 10 - Technical
Specification for filled weight). The Matrix Mini must not be installed in a
loft space. It must also be considered that the noise and vibration from
the Matrix Mini may be transmitted through the structure it is sited on.
Ensure the minimum clearance requirements are followed to allow servicing
of the unit.
2.12 Access and minimum clearance requirements: For emergencies and
maintenance the Matrix Mini must be easily accessible and have the
minimum clearance around it as laid out in Fig. 2.
Additional access to the front of the unit will be required to operate the
keypad and view the display.
2.13 Protection: The Matrix Mini must be located in a dry, frost free area.
2.14 Ventilation: Ensure an adequate air flow to cool the Matrix Mini. Separate
the Matrix Mini from other appliances that generate heat. Do not block the
vent holes on the front cover.
2.15 Water retention: Site the Matrix Mini 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. As part of the AB airgap (CAT 5 fluid
isolation) the Matrix Mini has a weir type overflow on the front, water will
be discharged from this area in the event of the failure of the inlet valve or
non-return valve.
2.16 Supply inlet pressure: The water supply inlet pressure must not exceed 7 bar.
2.17 Ambient temperature: The Matrix Mini must be sited in a location where the ambient
temperature does not drop below 4 °C or exceed 40 °C.

2.19 Static outlet pressure: The static outlet head must be 3 metres below pump maximum
cold fill pressure (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 Matrix Mini pump to the pipework connected to the
appliance outlet. However, care must be taken when mounting the Matrix Mini that any
noise is not amplified through loose panels or pipework.
2.21 Flexible hose: Only use the Altecnic Ltd hose supplied with the Matrix Mini.
2.22 Isolating valves: Separate system isolating valves (non-restrictive) must be fitted to allow
easy service of the Matrix Mini. Isolating valves must be mounted where specified to

3 KEY FEATURES
3.11 The Matrix Mini comprises of the following main components:-
1. Moulded tank – Main body of the Matrix Mini, comprising of an integrated water
tank with warning pipe and weir overflow and mounting the solenoid piston pumps,
manifold and controller.
2. Pump assembly – One or two piston pump units mounted into the moulded tank
with vibration isolating rubber mounts.
3. Outlet manifold – Brass manifold with pressure transducer used to monitor system
pressure and connection to the pump(s)
4. Programmable controller – Custom designed, user set controller, allowing system set
up and easy alarm connection.
5. Wall mounting plate – Robust stainless steel wall mounting plate allowing quick, easy
installation and removal if needed.
6. Moulded cover – Moulded acrylic capped ABS cover retained to the moulded tanks
with Dual LockTM fastening system for quick and easy access
3.12 Principle of operation: The pressurisation unit consists of a break tank and one or two
piston pumps. The break tank is supplied with mains water from the left to a float valve
and includes an overflow and weir to maintain an AB air gap in the tank. The unit is
connected to the heating/chiller system via a flexible hose which can exit the unit on
either the left or right. The pumps are connected via a flexible hose to the tank via a
rubber connector.
A pressure transducer monitors system pressure and if a reduction in system pressure is
detected, the controller runs the pumps until the system is re-pressurised to the
required pre-set level. If the unit only has a single pump connected it will run on a
30 minutes on/30 minutes off basis until this level is reached, if the unit is a twin pump
model the pumps run in duty standby mode (the controller will alternate which pump
starts first to even the wear on the pumps). The manifold is fitted with a non-return valve
to ensure system pressure is maintained once pressurised.

4 INSTALLATION
4.11 Fill valve flow restrictor guidelines: Ensure side entry fill valve is fitted with the correct
filter and flow restrictor combination (dependant on the mains water pressure) into the
G ½ threaded tail as outlined below:
Coloured insert - To be used for water pressure between 1 and 4 bar
White insert - The Matrix Mini is pre fitted with the white high pressure insert.
Change if the unit is slow to fill or the water pressure is low (below 4 bar).
4.12 Cold mains feed connection: The connection to the cold water mains inlet is made
using a suitable fitting to the G ½ male thread on the left hand side of the Matrix Mini.
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. (Do not overtighten).
4.13 Wall plate fixing:
1. When installing the Matrix Mini on a wall ensure suitable fixings for the wall
structure are used and are suitable to support the unit when fully filled with water
(see Section 10 for filled weights). The holes in the wall plate are 6 mm in diameter,
the maximum permissible screw head height is 3 mm.
2. All holes in the wall mounting plate must have fixings used in them as per the image
below, do not leave out fastenings as this will compromise the integrity of the
wall plate.
3. Ensure you have sufficent room around the area you are mounting the Matrix Mini to
allow installation, servicing and operation. See section 2.12.
4. Ensure wall plate is fixed to a flat vertical wall and the top of the plate is horizontal.

4.14 Pipework connections & guidelines:
1. Before connecting the Matrix Mini to the system ensure that system flushing has
been performed correctly and all foreign matter, including pipe scale, has been
removed.
Note: Foreign material from the system coming into contact with the expansion
vessel bladder could cause premature failure of the expansion vessel.
2. Isolating valves MUST be installed on the unit inlet and outlet, before connection to
the flexible hoses to allow the unit to be isolated if required. The isolation valve on
the outlet should be of a lockshield type. See Fig. 10.
3. A drain valve must be fitted on the outlet of the Matrix Mini before the isolation
valve. See Fig. 10.
4. The connection to the heating/chilling system is also made with the supplied flexible
hose and a 15 mm compression fitting. 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).
5. The connection to the heating/chilling system can be made to the left or right hand
side by routing the flexible hose supplied as detailed below.

6. The flexible hose and any wiring can be retained in the desired position using cable
ties and the two metal cable retention points on the top left and right of the Matrix
Mini tank. See Figs. 8 & 9.
7. The warning pipe should be connected to a suitable drain via a tundish enabling
visual warning of an overflow condition. The overflow fitting is designed to
use 19 to 23 mm diameter plastic waste pipe or connect to G ¾ threaded pipe.
Ensure there is a demountable joint in the pipe to allow the removal of the Matrix
Mini if needed.
8. Non-return valves, pressure reducing valves and RPZ valves MUST NOT be installed
between the Matrix Mini and the heating/cooling system. These devices will
prevent the pressure sensor from reading the system pressure and will lead to
incorrect operation of the unit.
9. The Matrix Mini should be connected to the system return header along with the
expansion vessels as specified in BS 7074. See Fig. 10.
4.16 Typical installation diagram:
4.17 Vessel sizing & location:
1. System expansion vessel sizing should comply with the BS 7074 Expansion Vessel
sizing calculation.
2. The pressurisation unit and expansion vessels should be connected to the system at
