Water purification filters are available from Instanta to ensure fresh tasting water. In hard
water areas, scale can cause problems. Fitting a scale reducer will help minimise scale but will
not eliminate scale completely.
NOTE: To avoid damage to the appliance, do not use any solder connections whilst pipes are
connected to the boiler.
NOTE:
Water that has been treated by the Reverse Osmosis process can become aggressive (due to
lack of minerals or Ions), and in extreme cases can cause leaching and corrosion of pipes, fittings
and other metal parts within the appliance.
If the appliance is being fed by water treated by Reverse Osmosis, we strongly recommend that the
water is tested regularly.
If you have any queries in this respect, please contact our customer services team.
d) OVERFLOW / DRAIN
The fitting kit includes a 15mm, straight push-fit coupling with a small piece of 15mm copper pipe
pushed into it. This connector must be pushed onto the corresponding brass overflow connection on
the services-bracket (alongside the solenoid).
If the overflow is to be extended, remove the copper pipe (supplied) and replace with 15mm pipe of
your chosen length. The pipe must have a continuous fall and should not be longer than 300mm (if a
longer run is required, use 22mm pipe to avoid airlocks. The overflow pipe should have no more than
four right angle bends and should discharge to a safe, visible position.
Under certain conditions the overflow pipe could vent steam, hot water or cold water and the
manufacturers cannot be held responsible should damage occur from such discharge if the
overflow pipe has not been directed to a suitable position where overflowing water can run away
safely.
Failure to connect the overflow-outlet to a permanent waste or drain, could lead to property damage
from flooding.
If in all circumstances, it is absolutely not possible to direct the boiler overflow-outlet to a permanent
waste or drain, then the mains water supply to the boiler should be isolated and the unit switched
off whenever it is left unattended for long periods (e.g. overnight).
Whilst every reasonable precaution is taken to prevent an overflow, Instanta cannot be held
responsible for any damage caused as a result of incorrect installation or blockage of the overflow
or failure to direct the overflow to a safe outlet.
VENT PIPE:
A small silicone rubber tube connects the tank-lid to the back panel. Ensure this is connected (and
hasn’t come off in transit) and that th
e outlet fitting in the back-panel is not obstructed.
