1.2 Danger Warnings
For safety reasons your warewasher MUST be bonded to adjacent metalwork or
earthed so that it is the same potential (i.e. voltage).
A means for disconnection that has all poles separation of more than 3mm must
be incorporated in the fixed wiring in accordance with wiring rules (►4.3).
If a mains supply cable is damaged, it must be replaced by a cable supplied by
Classeq, its service agents or similar qualified persons, in order to avoid hazards.
All mains electrical work must be carried out in accordance with local and
national regulations, and by a qualified electrician (►4.4.1).
The warewasher MUST be disconnected from its power source during cleaning,

the rating plate (►2.3).
If Classeq warewashers are used outside the designation for the appliance, you
invalidate your warranty and make the appliance unsafe.
Maximum inlet water pressure is 400 kPA and minimum inlet water pressure is

Before cleaning the Wash Chamber, ensure all sharp items, such as broken glass
or other items which could cause injury, are removed carefully.
DO NOT use cleaning agents that contain CHLORINE, BLEACH or
HYPOCHLORITE.
Wear the correct Personal Protective Equipment, e.g., gloves and goggles, when
handling chemicals and observe all safety notes and dosing recommendations
printed on the packaging. (►4.7) (►7.5) (►9.1).

1.4 Cautions
Damage to the warewasher caused by limescale or poor water quality will NOT
be covered by the Manufacturer’s Warranty (►7.3).
In hard water areas (>3°dH), DO NOT run the warewasher without the use of

the warewasher. Failure to observe this warning will invalidate the warranty.
Warewashers with WS in the model type are fitted with an internal water
softener.
DO NOT run the warewasher without salt in the Salt Reservoir as this will allow
limescale to build up. Limescale deposits in the warewasher will invalidate the
warranty (►5.5) (►7.4.1).
Only use granulated salt (max. grain size 5 –7 mm). Salt tablets are not suitable
(►5.5) (►7.4.1).
DO NOT add any chemicals, such as detergent or rinse aid to the Salt Reservoir.
These will cause damage to the warewasher (►5.5) (►7.4.1).
Only use commercial grade detergents and rinse aids in your warewasher
(►4.7).
If the Salt Reservoir Cap is not properly secured, water and/or chemicals can
