PLUMBING
LIMESCALE
Permissible mains inlet water pressure:
Minimum 20kPa / 0.02MPa / 0.2bar / 8psi
Maximum 1000kPa / 1MPa / 10bar / 145psi
The inlet water must be potable and free of contaminants.
Inlet water should be 5-30°C, pH 6.5-8.5, maximum chlorine
content of 100 mg per litre, total hardness of 60-180ppm. Do
not connect the machine to pure reverse osmosis water or other
aggressive types of water. Ensure that the equipment is installed
according to local plumbing & water regulations.
In common with all water boiler manufacturers, service calls
resulting from lime scale are not covered by warranty. Fitting
a scale reducer is recommended, especially in hard water areas. This can reduce the build-up of scale but may not stop it
altogether. The frequency that descaling is required depends on
the local water supply; hard water areas need more attention.
Machines typically need descaling every 3-6 months. Descaling
of the machine requires removal of panels and must only be carried out by qualified service personnel who must read the full
warnings contained in this manual, and must contact the manufacturer for detailed descaling instructions. Aggressive descaling
agents can damage the stainless steel tank. Citric acid based
descaling agents are recommended, the tank must be fully
flushed through at least twice to remove all residues.
Installation procedure:
• Fit a stop valve and suitable fitting on a cold water line (e.g. 3/4”
x 1/2” 311 or washing machine type stop valve).
• The boiler requires a suitable food grade inlet hose with 3/4”
BSP female elbow fitting which will attach to the underside of
the machine.
• Make sure that the pre-attached sealing washer is fitted on
both ends.
• Turn on the water to flush any impurities, dust etc. from the inlet
hose and water pipe. Allow several gallons through.
• Connect right-angled tailpiece of the hose to the inlet valve of
the boiler (again 3/4” BSP). Make sure the sealing washer is
fitted here again.
• Turn on water and check for leaks.
NOTE: Using a non-food grade hose (e.g. a washing machine hose) will usually result in off-tastes & smells in the
water, and can possibly be toxic.
It is recommended to de-scale the machine every 3 months in
hard water areas and every 6 months in soft water areas. Descaling should be carried out by a service agent. It is also recommended to clean the urn after each days brewing using a proprietary urn-cleansing compound.
CLEANING
The exterior of these machines may be cleaned with a damp
cloth and a light detergent. Do not use abrasive cloths or creams,
as this will spoil the finish of the machine. Do not use a water jet
or spray. Beware of accidentally operating the draw off tap when
cleaning the front of the machine.
ACCESSORIES
The following accessories can be used with the brewer.
• Grinder p/n.1000890
• Urn p/n.1700169
• Filter Paper p/n.8000151
Electrical Installation Procedure
1000650# - 5.6kW/230V ac
This device must be connected to a suitable 30A single phase power supply. This should be done by a qualified electrician. If the device is installed
by fixed wiring means the addition of an isolation device is required in
close proximity to the equipment. If the device is intended to be powered
via an industrial plug the plug/socket outlet should be easily accessible.
Fixed wiring insulation must be protected by the insulating sleeving having the appropriate temperature rating.
1000856# - 5.6kW/400V ac
This device must be connected to a suitable 15A three phase (with
neutral) power supply. This should be done by a qualified electrician. If
the device is installed by fixed wiring means the addition of an isolation
device is required in close proximity to the equipment. If the device is intended to be powered via an industrial plug the plug/socket outlet should
be easily accessible. Fixed wiring insulation must be protected by the
insulating sleeving having the appropriate temperature rating.
This appliance must be earthed
