Zanussi DI 720 Instructions For The Use And Care page 7

Water supply connections
This Zanussi dishwasher may be
connected to either a hot or cold water
supply, and for convenience, it is well
worth having it permanently «plumbed
in». Just make sure that the water
pressure is within the limits given in the
technical data, and, in the case of a hot
water supply, that the temperature never
exceeds 60°C (140 °F).
Your local Water Authority will advise you
on the average mains pressure in your
area. Where the water is supplied via a
cold water storage cistern, or hot water
cylinder, you can work out the pressure
yourself in both cases by measuring the
vertical distance (or «head») between the
machine's inlet hose, and the outlet from
the cold water storage cistern; allowing
roughly 1 psi for every 2 feet.
As to the making of the connection itself,
the coupling nut fitted to the machine's
supply hose is designed to screw onto
either a 3/4 inch gas thread spout, or to a
purpose made quick-coupling tap such as
the Press-Block.
To make this easier, the hose itself may be
turned to the right or left. In either case,
be sure to incorporate the strainer
supplied with the machine onto the joint
(fig. 2).
