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.
4.5 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.
Classeq Under Counter Range - User Manual
26
Minimum supply flow rate:
Without Water Softener: 11 litre/minute.
With Water Softener: 4 litre/minute.
Water hardness:
Caution
Damage to the warewasher d caused by limescale will NOT be covered
by the manufacturer’s warranty (►12).
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).
Your water supply to the warewasher is from a suitable external water softener unit.
4.5.2 Water hardness explained
Water hardness occurs because certain chemicals in the rocks through which the water
passes on its way to the consumer slowly leach out into the water.
The problem shows itself in two forms:
1. When hard water is heated the chemicals come out of solution and appear as solid
particles (limescale) that are carried round the warewasher. These particles are formed
most quickly at the hottest part of the warewasher – typically, the rinse element and the
Rinse Tank. This is why the Rinse Tank is the best place to look to judge if limescale is
being formed in a warewasher.
2. Most commercial washing chemicals operate much less efficiently in hard water, and
this will often show as poor results, failure to remove tannin stains or condensation on
glasses. Tannin stains appear to cling to the hard water film in the drink, which then
clings to the surface of the cup or saucer. With soft water this is not the case.
Some types of hard water do not produce limescale when heated, but still reduce the
performance of washing chemicals, as mentioned above. This is known as permanent
hardness. Temporary hardness is when the hardness can be largely removed by conversion
into limescale by boiling.
Classeq Under Counter Range - User Manual
27
If limescale is produced inside a warewasher it will cause a
number of maintenance problems, for example:
Coating of heating elements leading to slow heating
and eventually, element failure.
Blockage of rinse jets, showing as poor results.
Wear of bushes in the centre boss, showing as poor
results and possibly wash water passing backwards
into the rinse system.
Blockage of the rinse aid injection point in the boiler.
White marks appearing on glasses, dishes and cutlery.
Dishes or cups may appear dirty even after a wash.
Especially coffee or tea cups.
Discolouration of the inside of the warewasher,
making cleaning difficult.
Blockage of hoses due to limescale deposits “furring
up” the inside of the hoses.
When limescale is found, it must be removed with commercial de-scaling chemicals, used
with care in accordance with the instructions on the product.
The descaling instructions in this manual should always be followed.
The Rinse Tank is difficult to de-scale and a service engineer may be required to carry this
out.
Your local water board / water supply company should be able to tell you if the water in your
area is hard or soft.
Alternatively you can establish the hardness of your water supply yourself using a simple
water hardness testing kit.

4.5.3 Water supply hose connection
Classeq recommend installing a shut off valve in the mains water supply line near the
warewasher such that it is easily accessible.
Your warewasher is supplied with a new UK Water Regulations Advisory Scheme (WRAS)
approved water inlet hose, requiring a G¾” (¾” BSP) male threaded connection at the mains
water outlet.
Warning!
Use only the hose supplied with your warewasher to connect it to the
water supply. Old existing, defective or damaged water supply hoses
MUST NOT be used.
Connect the 90 degree bend connector of the water supply hose to the inlet on the back of
your warewasher and the straight connector to the mains water supply.

Ensure the rubber seals are in place in the connectors.
Hand tighten the connectors only.
Ensure all connections are watertight before using your warewasher.
4.6 Waste Water and Connection
4.6.1 Waste water system type
The waste system of your warewasher will vary depending on the variant. You can identify
the type of drain your warewasher has by checking whether there is a Drain Plug, as shown,
present in the Wash Sump.
Warewashers with a Drain Plug are gravity drain type and warewashers without a Drain Plug
are pumped drain type.
Classeq Under Counter Range - User Manual
31
4.6.2 Waste water connection
Gravity drain warewashers:
If your warewasher has a Drain Plug fitted in the Wash Sump the waste hose will fit into
Ø40mm plumbing or over a Ø20mm spigot.
The waste hose for this type of warewasher has to lead away below the base of the
warewasher.
Pumped drain warewashers:
The outlet end of the waste hose of a pumped drain type warewasher can be trimmed to fit a
variety of sizes of pipes / spigots.
The waste plumbing for this type of warewasher can be up to a maximum of the following
heights from the base of the warewasher:
Warewasher size
Max waste height (mm)
470mm (D400/G400)
540
570mm (D500/G500)

9. Decommissioning
If for any reason you need to remove or decommission your warewasher, do so in
accordance with local and national regulations.
Classeq recommends the following procedures are followed.
9.1 Flush Out Chemical Dosing Systems
Prior to removing any chemicals refer to all safety statements on the chemical bottles for
dealing with any spillage.
Warning!
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.
1. Remove the chemical tubes from the chemical bottles.
2. Place the ends of the tubes into a container of water.
3. Use the commissioning menu to prime the Rinse Aid and Detergent Pumps to draw
water all the way into the warewasher.
4. Fill and drain the warewasher to remove any chemical residue.
5. Ensure the bottles are then capped to prevent any spillage.
9.2 Drain the Warewasher
6. Ensure the warewasher is fully drained (►6.9).
7. Remove the Waste Hose from the drain standpipe; ensure any spilt liquid is dried
prior to advancing to the next stage.
9.3 Disconnect the Warewasher
8. Turn off the mains electrical supply at the socket / isolator / junction box.
When disconnecting the warewasher from the mains electrical supply:
o Warewashers with an electrical plug, always pull the plug. Never pull the cord
itself.
Classeq Under Counter Range - User Manual

o Warewashers that are hardwired (i.e. no plug), must be disconnected in
accordance with local and national regulations. Classeq recommends this is
performed by a qualified electrician.
9. Once the electrical supply has been disconnected, disconnect the equipotential wire
from the stud at the rear of the warewasher.
10. Turn off the water supply to the warewasher and disconnect the Water Supply Hose
from the mains water supply, ensuring any spillage is cleared up.
9.4 Drain the Rinse Tank / Boiler
11. Remove the lower Front Panel from the warewasher using a 3mm hex key.
12. Locate the Boiler Drainage Hose. Ensure the Hose protrudes from the front of the
warewasher.
13. Position a container large enough to hold eight litres of water so that the Hose will
drain into it.
Classeq Under Counter Range - User Manual

Warning!
If the warewasher is being drained immediately after use, the water
draining from the Boiler Drainage Hose may be as hot as 95°C.
14. Loosen the Jubilee Clip and remove the Drain Plug, ensuring the water flows into
the container. Once fully drained replace the Drain Plug and retighten the Jubilee
Clip.
15. Replace the Front Panel, and ensure all cables and hoses are secured to the
warewasher to prevent tripping hazards. The warewasher is now ready to be
removed.
