1 IMPORTANT FACTS: READ BEFORE COMMENCING PUMP INSTALLATION
A Water storage capacity.
1.11 The Matrix Maxi has a usable water volume of approximately 18 litres; the length of time
the Matrix Maxi 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 shaft seal. See Section 6.26 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 Maxi 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 Maxi, this will cause damage and possible leakage.
1.17 Flux: Solder joints must be completed and flux residues removed prior to Matrix Maxi
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 4.15.
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.
