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.

2.18 Pipework: For optimum performance inlet and outlet pipework must be a minimum of

15 mm pipe.

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

allow the system isolation and removal of the Matrix Mini if needed. See Section 4.14 for

installation details.

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.
