Water connection

Water inlet connection

This appliance may be fed with either hot

(maximum 60 °C) or cold water. Nevertheless

we advise you use a cold water supply. A hot

water supply is not always efficient with heavily

soiled crockery as it shortens the washing

programmes a lot. For making the connection

itself, the coupling nut fitted to the appliance

inlet hose is designed to screw onto a 3/4" gas

thread spout or to a purpose made quick-

coupling tap such as the Press-block. The water

pressure must be within the limits given in the

‘Technical data’. Your local Water Authority will

advise you on the average mains pressure in

your area. The water inlet hose must not be

kinked, crushed, or entangled when it is being

connected. The appliance features inlet and

drain hoses which can be turned either to the

left or the right to suit the installation by means

of the locknut. The locknut must be correctly

fitted to avoid water leaks. If the appliance is

connected to new pipes or pipes which have not

been used for a long time, you should run the

water for a few minutes before connecting the

inlet hose. This appliance has been fitted with

safety features which will prevent the water

used in the appliance from returning back into

the drinking water system. This appliance

complies with the applicable plumbing

regulations.

Caution! Do not use inlet and

drain hoses which have

previously been used on

another appliance.

Water drain connection

The end of the drain hose can be connected in

the following ways:

• To the sink outlet spigot, securing it to the

underside of the work surface. This will prevent

waste water from the sink running into the

appliance.

• To a stand pipe provided with venthole,

minimum internal diameter 4 cm.

max.

4000 mm

min. 400 mm

max. 850 mm

The drain hose can face either to the right or left

of the appliance. Ensure the drain hose is not

bent or squashed as this could prevent or slow

down the discharge of water. The sink plug must

not be in place when the appliance is draining as

this could cause the water to syphon back into

the appliance. If you use a drain hose extension,

the internal diameter must be no smaller than

the diameter of the hose provided. Likewise the

internal diameter of the couplings used for

connections to the waste outlet must be no

smaller than the diameter of the hose provided.

Our appliances are supplied with a security

device to protect against the return of dirty

water back into the appliance. If the spigot of

your sink has a "no return valve" incorporated

this can prevent the correct draining of your

appliance. We therefore advise you to remove

it. When connecting the drain hose to an under

sink trap spigot, the entire plastic membrane (A)
