BLOCK SALT SOFTENER
INSTALLATION INSTRUCTIONS
Plumbing Regulations
This water softener should be installed in accordance
with the plumbing regulations. Copies are
available from your water softener dealer. Ask for.
WRAS Information for Installation of Ion exchange
Water Softeners for Systems Supplying Water
for Domestic Purposes. June 2007 No 9-07-01.
Water pressure
The recommended operating pressure is between
1.5 and 6 bar (20 and 90psi), but the pressure should
not be below 1 bar (15psi) when water is flowing, or
exceed 8 bar (120psi). To check the water pressure you
need to connect a pressure gauge to the garden tap,
kitchen tap, or any other tap connected directly to the
mains water supply. Alternatively you may contact
the local water supplier who will tell you the water
pressure in your area. If the water pressure is above
6 bar we recommend installing a pressure limiting
valve which is available from your softener supplier.
