4.Installation Instructions
The site:
Ensure that there is sufficient space for the installation, servicing and easy access to
all mains isolator switches / valves (i.e. electricity and water).
Ensure that the surface the appliance is going to be installed onto is adequately stable
and capable of supporting the appliance during normal operation (see site
requirements).
Once installed ensure the appliance is stable, with its weight being distributed equally
and does not tilt more than 3° in any direction.
Adjuster feet:
After removing the machine from the transport pallet ensure all the feet are adjusted to suit the
surface where the appliance is being installed.
For further instructions see installation and operation manual.

6.Warning and safety information
The machine should only be operated at or within the voltage specified on the rating plate (►5). The
installer and user are responsible for ensuring the installation and operation of this machine are in
accordance with local and national regulations.
The machine is not fitted with a heat interlock but should be allowed to fully heat to the correct
temperatures before use.
Only use commercial grade detergents and rinse-aids within your machine.
DO NOT use electrical extension lead(s) to supply power to your machine.
Damage to the machine caused by lime scale, or poor water quality will NOT be covered by the
Manufacturer’s Warranty.
Children should be supervised to ensure that they do not play with, or operate the machine.
When disconnecting your machine from the mains electrical supply:
Machines hard wired (i.e. no plug), this must be disconnected in accordance with local and national
regulations; Classeq recommends this is performed by a qualified electrician.
Always remove excess food from the dishes before loading.
Caution
DO NOT use the machine
as a waste disposal unit.
Do not insert any items or parts of your body between moving components, as this could cause injury.
Beware of touching or placing items onto the wash tunnel of the machine, as this can get hot during use.
The drive motor and gearbox assembly weighs over 15kg. When removing these items care must be
taken to ensure that the weight is supported correctly.
The dryer unit weighs more than 50kg and should be handled with care. When installing the unit a lifting
trolley should be used.

Electric Supply:
Electrical connection:
Electrical connections MUST be carried out by an authorized technician and in accordance with local
and national regulations.
As a minimum Classeq recommends the following standards are maintained:
All appliances are connected via a residual current device (R.C.D.) or earth leakage protection device.
EN60204:
Supply isolator switch has all pole separation of more than 3mm.
EN60335:
Connect to an equi-potential conductor, connection stud located at bottom of the appliance to the rear;
this is in addition to the earthed electrical supply.
Prior to connecting the appliance, ensure voltage and supply fuse comply with rating plate.
Electrical rating: Note: Electrical supply can be
either side of the appliance. The
appliance not supplied with the
electrical plugs.
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.

Water Inlet and Waste out let:
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.
Old existing, defective or damaged water supply hoses
are NOT to be used when installing the appliance.
Commercial appliance wash results will be affected 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.
Note: Water supply can be either side of the machine.
IMPORTANT:
All supplier warranties are void if lime scale is present within an appliance
If the above requirements are not adhered to, the performance of the appliance will be impaired

Waste outlet:
The CST is a gravity drain machine, upon installation the
waste must be configured as stated in this manual.
All installations should be fitted with a running ‘P’ trap to
ensure hygiene.
Ø40mm (1 ½”) standpipe required, must be lower than
the baseline of the wash tank.
Drain hose must be a close / tight fit into the drain pipe
to reduce odours from the drain system.
To ensure correct drainage, the height the sites drain is from the floor / surface the machine sits
upon MUST be within the following
Waste hose must flow down from the waste outlet to the drain.
Joint between standpipe and waste hose must be water tight.
If you have any doubts about the drainage system on the machine, please contact either Classeq or
your dealer/agent.

8.Commissioning Instructions
Rinse aid & Detergent:
The CST is not fitted with internal chemical dosing pumps, these will need to be fitted during the
installation.
A terminal block is provided on right hand side of the wash tank for connecting the electrics of the
chemical pumps.
Note: Isolate the machine prior to the access and connection of the chemical pump terminal block.
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.

(ST4)
60ºC
The manual reset safety thermal trips on the machine are set to the following values and cannot be
adjusted:
Wash tank –85°C
Rinse boiler –95°C
Air blower –85°C
Table end limit switch
It is very important that the table end limit switch be installed at the end of the exit table and the arm
adjusted so that it is activated by the basket before it reaches the end of the table. The cable should
be routed through the small cable gland at the rear of the machine and plugged into the harness at the
connector near the small terminal block. The switch should be wired on the normally closed circuit.

Electrical supply setup
If the machine is fitted to a hot water supply (maximum temperature of 55°C) then the electrical supply
to the machine can be changed (►7). This is done by turning off CB2, this turns off one of the banks
of elements used in the rinse boiler and reduces the current required.
Cold fill (45A per phase)
Hot fill (32A per phase)
Installing the splash guard (only if not dryer fitted)
Once the machine has been installed and all tabling has been aligned the splash guards should be
fitted to the exit of the machine.
Remove the 3x M5 screws on either side of the exit and use these to fasten the splash guard in place.
Align the splash guard to the front of the machine and the side of the exit as best as possible. Once
fitted the splash guards should be sealed against the tabling.

11. Changing orientation
CST is designed to allow adaption to a change in direction of travel during the commissioning of the
machine.
Ensure the machine is fully drained prior to commencing any changes.
Remove all the curtains and the cassette assembly from the machine.
Danger
For safety reason turn
off all electrical
supplies to your
machine before
following these steps.
Remove rear top and rear bottom panels in order to get access to wash and rinse hoses.
When changing the direction of the CST care must be taken not to misplace or damage the sealing O-
rings.
11.1 Changing wash and rinse arms system.
Remove the wash arms and cassette from the machine.
Remove wash arm brackets and fixing tubes. Take note shorter fixing tubes used at bottom and
longer fixing tube used at top.
Remove rinse arm hose from rinse bush.
Remove rinse arms and associated brackets.
Loosen and remove the top wash manifold.
Remove the blanking covers from the remaining holes
Loosen the jubilee clips for the bottom wash manifold.
Rotate the bottom wash manifold 180° to the new position and fasten using long fixing tubes.
