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 SPU 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 SPU 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 SPU 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 technical section 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 SPU
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.
