INSTALLATION INSTRUCTIONS
These instructions are intended for the installer of this pressure booster set. Please follow them
carefully.
The unit should only be installed by a competent person;
A competent person is someone who is

1.1
ADDITIONAL WARNINGS
READ GENERAL SAFETY INFORMATION 0.0, WARNINGS 0.1 and CAUTIONS 0.2, 0.3 & 0.4
1.2
ADDITIONAL CAUTIONS
1.2.1
READ GENERAL SAFETY INFORMATION 0.0, WARNINGS 0.1 and CAUTIONS 0.2, 0.3 & 0.4.
1.2.2
Ensure the Y strainer (100um) and isolation valve (supplied as loose item) is installed on the inlet to
the breaktank (see fig 1.3), failure to install these will cause the solenoid to jamb and overflow the
break tank.
1.2.3
Ensure the quick release filter (supplied as loose item) is installed in the breaktank overflow warning
pipe (see fig 1.3)
1.2.4
Mains water pressure to unit should be between 1.0 and 3.0Bar. Ensure a pressure reducing valve set
at a maximum of 3.0Bar is installed on the inlet to the breaktank if the mains water supply pressure
exceeds 3.0Bar.
1.2.5
Ensure the pump is primed before starting otherwise the pump seal will be damaged and cause a leak
(see fig 1.1a).
1.2.6
The maximum static outlet pressure is 12 metres for AB5‐45 (height from the pump discharge to the
highest point of the system pipework), or 8 metres for AB5‐35.
1.2.7
Ensure the control vessel air charge is set correctly (1.3Bar) otherwise erratic operation will occur
(pump will not start/stop correctly).
1.2.8
We recommend system pipework should be 22mm only reducing to 15mm at the terminal fitting.
1.2.9
Ensure the pressure vessel that is factory fitted to the pump assembly is still tight after transit, it
should be hand tight only, DO NOT over tighten the pressure vessel, this will lead to damage to the
vessel/fitting and subsequent leakage (see Fig 1.1b).
