Contact your distributor, a qualified electrician, or
Classeq
if you
are unsure how to check this.
The electrical supply must incorporate a disconnection device
(circuit breaker / fuse) that complies with local and national
regulations.
Your warewasher must be connected directly to the mains
electricity using the mains electrical cable provided. DO NOT use
electrical extension lead(s) to supply power to your warewasher.
DANGER!
All mains electrical work
must
be carried out in
accordance with local and national regulations
by a qualified electrician.
4.4.2
Electrical connection specification
Depending on the specification of your warewasher it may be
supplied with or without a moulded mains electrical plug.
When hard wiring the warewasher into the mains outlet, use a
multimeter or voltmeter to ensure that the connection point is
electrically isolated before attempting to make the connections.
4.4.3
Electrical cable specification
If the mains electrical supply cable is damaged or has
deteriorated, it MUST be replaced by a cable or cord assembly
supplied by
Classeq
, its service agents or suitably qualified
persons in order to avoid hazards, and be to the following
minimum specifications.

Equipotential bonding
DANGER!
For safety reasons your
warewasher
MUST be
bonded to adjacent metalwork or earthed so
that it is at the same potential
(i.e. voltage).
Consult your distributor,
Classeq
or a qualified electrician if you
are unsure how to do this.
The equipotential
bonding stud is
located at the rear of
the warewasher and
is fitted with an M5
nut. Use the 8mm
spanner to connect
the bonding wire
terminal to this
location and ensure the nut is securely fastened.

Water Supply and Connection
4.5.1
Water supply restrictions
Commercial warewasher wash results may be affected by
external conditions such as incoming water temperature,
pressure, hardness and choice of chemicals.
Supply water temperature:
4°C minimum
55°C maximum
Supply water dynamic pressure:
The dynamic pressure of the water supply will determine
whether your warewasher needs additional equipment to be
installed in the water supply system, as follows:
Measured water pressure
Consequence
0 to 2 bar (0 to 200 kPa)
An external rinse booster pump
must be installed to increase the
pressure of the water supply to the
warewasher.
2 to 4 bar (200 to 400 kPa)
No modifications required -
warewasher can be installed with a
direct hose connection to the
existing water supply.
>4 bar (400 kPa)
A pressure reducing valve must be
installed to reduce the pressure of
the water supply to the
warewasher - maximum allowable
pressure is 4 bar.
Minimum supply flow rate:
Without Water Softener: 11 litre/minute.
With Water Softener: 4 litre/minute.
Water hardness:
Caution
Damage to the
warewasher
caused by limescale
will
NOT
be covered by the manufacturer’s
warranty (
For the longevity of your warewasher, and to ensure you get
consistently good washing results, your warewasher must wash
with soft water, ie water that contains a low concentration of
ions, in particular ions of calcium and magnesium. There are
three ways to achieve this:
The supply water must be naturally soft.
Your warewasher is specified to be fitted with an internal
Water Softener (models
D400DUOWS
and
D500DUOWS
).
