3.3 Electrical connection :
All electrical connections MUST be carried out by an authorised
technician and in accordance with local and national wiring regulations.
As a minimum ‘Classeq’ recommends that the following standards are
maintained :
• All appliances are connected via a residual current device (R.C.D.)
or earth leakage protection device.
• EN 60204
Supply isolator switch must have all pole separation of more than 3mm.
• EN 60335
The appliance must be connected to a equi-potential conductor , the
connection stud is located at the rear of the appliance (a suitable ring
terminal shall be required), this is in addition to the earthed electrical supply.
Prior to connecting the appliance, ensure that the voltage and the supply
fuse complies with the rating plate on the appliance.
If the supply cable is damaged, it must be replaced by a cable or cord
assembly supplied by Classeq, or its service agents, or to the following
minimum specification.

3.4 Water connection :
The appliance comes with a water supply hose requiring a G¾” (¾” BSP) male
threaded connection at the mains water supply, upon installation and
commissioning all water joints must be checked for leaks.
New hoses supplied are to be used. Old existing, defective or damaged water
supply hoses are NOT to be used when installing the appliance.
Commercial appliance wash results will be effected by external conditions such
as incoming water temperature, pressure, harness and choice of chemicals.
For the longevity of any water related devices and to ensure you get consistently
good results it is essential your machine is either fed from a soft water supply , or
your Classeq appliance is connected to an appropriate water softener.
IMPORTANT - All supplier warranties are void if lime scale is present within
an appliance.
Page 4
3.3.1 Electrical rating :
Within the ‘Classeq’ range several of the 500mm² basket appliances can
be either down rated or up rated electrically, such a procedure MUST be
carried out by a ‘Classeq’ approved technician.
The down / up rating of the machine is carried out by configuring the
terminal block within the appliance to the following
13 Amp – Single phase
• Links removed between L1, L2 and L3
• Ensure link remains between neutrals (N)
30 Amp – Single phase
• Ensure all link remains between lives
terminals (L1, L2 and L3)
• Ensure link remains between neutrals (N)
Three phase
Only Eco3 and H750 appliances can be converted to three phase, this is performed
by removing electrical links at the terminal between L1 L2 & L3, then installing a new
5 core supply cable, i.e. L1, L2, L3, N and Earth (PE).

prior to removing any panels all electrical supplies MUST be
isolated. An Allen key is required for this operation.
A coil of PVC hose is attached to each chemical pump, un-
coil PVC hose and feed through either the slots just behind
the chemical pumps, or out through the rear of the base.
After to feeding the PVC hose into the chemical bottle, push
the bottle weight supplied onto the end of each PVC hose.
Ensure the correct chemical tubes now go to the corresponding chemical
bottles. (i.e. rinse aid hose into rinse aid bottle).
WARNING : Only rinse aids and detergents developed for commercial
glass and dishwashers are to be used, rinse aids must be suitable for water
temperatures down to 40°C.

5.3 Switch the machine on :
Ensure that both the water and electrical supply are connected and switched on,
then depress the ‘ON/OFF’ switch located on the fascia of the machine.
The machine will now automatically fill and heat, during this process the door
should remain closed, allowing the process to be completed quickly.
5.4 Machine ready to operate :
It is IMPORTANT after switching the appliance on each day, to allow 25 minutes
before starting the first wash cycle; regardless of the fact that the green Ready
light will already be illuminated.
The appliance is designed to only start a cycle when the correct temperatures
are achieved, so there may be a pause between a cycle being selected and the
cycle starting
5.5 Starting a cycle :
To start a cycle, open the door, load the first basket, ensuring that
bottom and top arms rotate freely.
Close the door, then depress the ‘Cycle’ switch , the cycle will now start once
the appliance has achieved its correct temperatures, during the cycle the ‘Cycle’
lamp will be illuminated.
Once the ‘Cycle’ lamp has gone out (at the end of the cycle)
open the door and remove the basket, then reload the machine and
repeat as required
5.6 Draining :
During normal operation your appliance will automatically drain away any
excess water.
It is very important the machine is drained down at the end of each working
day and the door is left open to allow drying.
The machine should never be left full of water if you are switching the
machine off.

8.0 De
8.0 De- -commissioning commissioning
If for any reason you require to remove or, de-commission your appliance, then
do so in accordance with local and national regulations. As a minimum
‘Classeq’ recommends the following procedure is followed.
• Remove chemical tubes from the chemical bottles, ensuring bottles
are then capped to prevent any further spillage; refer to safety
statement on chemical bottles prior to and for dealing with any spillage.
• Ensure the appliance is fully drained in accordance with section 5.6 of
this manual, once completed remove the waste hose from the drain
standpipe; ensure any spilt liquid is dried prior to advancing to the next
step.
• Switch off mains electrical supply at wall / isolator / junction box.
• If the appliance is connected via an electrical plug, disconnect this from
the socket.
• If the appliance is hardwired into the mains, then this must be
disconnected by a qualified electrician in accordance with local and
national wiring regulations.
• Once the electrical supply has been disconnected, ensure the
equi-potential / earth bonding wire is removed from the stud at the rear
of the appliance.
• Turn off the water supply to the machine; and disconnect water supply
hose from mains water supply; ensuring any spillage is dried prior to
moving onto next step.
• Remove the front lower panel, using an Allen key
• Now locate the ‘Boiler drainage hose’, as shown,
ensure this protrudes from the front of the appliance,
and you have a container large enough to hold 8
litres of water.
CAUTION If the appliance is being drain
immediately after use, water draining from the
‘Boiler drainage hose’ may be up to 80°c.
• Loosen the jubilee / hose clip and remove the
stainless steel drain plug, ensuring the water flows
into the container mentioned above. Once fully
drained replace the stainless steel plug and
retighten the jubilee / hose clip.
• Replace the front panel, and ensure all cables and hoses are secured
to the appliance to prevent tripping hazards. The appliance is now
ready to be removed.
