Page 9: Location
2 LOCATION - GENERAL 2.11 Location: The Flowpress Mini must be located on a solid wall of sufficient strength to support the filled weight of the Flowpress Mini, close to the water source and a suitable exclamat overflow position (see Section 10 - Technical Specification for filled weight). The Flowpress Mini must not be installed in a loft space. - Page 10 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 Flowpress Mini pump to the pipework connected to the appliance outlet. However, care must be taken when mounting the Flowpress Mini that any noise is not amplified through loose panels or pipework.
