10.0 - MAINTENANCE
The boiler should be periodically checked for scale build-up. The frequency depends upon
hardness of the water and whether or not an effective scale reducer is fitted.
Apart from scale removal no regular maintenance should be required. Spare parts and accessories
are available from Instanta Limited

DE-SCALING:
To de-scale your machine, first disconnect from power supply and allow to cool down.
Disconnect water tube and electrical plug/lead from water font, and slide under-counter unit
forward to allow easier access to lid/tank.
Remove rear-lid (NOT front-lid). There are four clips holding the lid to the case. These are situated
25mm from each corner. To remove the rear-lid, insert the tip of a screwdriver or round ended
knife into the gap between the case and the lid and twist on each corner. After removing the lid,
the tank is accessible.
Remove the tank lid by taking out the four fixing screws (six on UCD47 models). Lift out the baffle
plates on the inside of the tank. Empty the water from the tank.
Remove as much scale as possible by hand. Any scale which is difficult to remove can be dissolved
by using a solution of Renegite de-scaler. Wipe clean the level sensing probes.
Ensure all traces of de-scaler are removed before replacing tank-lid and using the boiler again.
Rather than frequently de-scaling the machine it may be preferable to install an effective scale
reducer or WRAS approved water softener. This will reduce the frequency of de-scaling but will not
remove scale completely in some areas.
