MAINTENANCE:
This machine has been designed to give many years of trouble free service.
The only regular maintenance required is occasional de-scaling.
Descaling Procedure:
 Isolate machine from power supply.
 Isolate machine from water supply.
 ALLOW TO COOL COMPLETELY!
 Drain water from machine.
 Remove all lids.
 Remove as much scale as possible by hand, paying particular attention to level probes
(White plastic with steel tab). Be very careful not to damage any attachments.
 Use ScaleKleen, Marco part No. 8000270 or similar. Follow instructions carefully.
 Thoroughly clean and flush the machine before re-use.
 Follow installation and first time operation instructions.
CLE ANING:
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.
NB: Beware of accidentally operating the draw off tap or push button when cleaning the front of the
machine.
LIMESCALE:
In common with all water boiler manufacturers, service calls resulting from limescale 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. Descaling of the machine
should ideally be carried out by qualified service personnel.
