6. Repeat this operation once again.
Following this, allow 2 boiler containerfuls

Before making your first pot of delicious
coffee, we recommend rinsing the coffee
maker by running one or two cycles with
water only, without ground coffee in the
filter basket. This will remove any possible
dust which may have settled during
shipping.
Be sure that the water chamber is empty.
Remove any literature, etc if found in the
water chamber.
■ The lid of the glass carafe must be
properly positioned during the brewing
process. The front hooks have to be inside
the carafe and the rectangular part of the
lid to be pushed down so that it engages
with the handle of the glass carafe.
■ To release the lid push the rectangular
part of the lid upwards.
■ Make sure that the swivel filter is closed
properly during the brewing process.
Push in firmly until the handle touches the
side of the coffee maker and filter “clicks“
into place.
■ Caution: If the swivel filter is not closed in
properly the “Stop ‘N Serve” can not
function. This may cause hot water or hot
coffee to overflow.
■ The “Stop ‘N Serve” mechanism is
opened as long as the glass carafe is
inserted into the machine and sits
properly on the warming plate and the
swivel filter is closed properly. When
brewing coffee make sure the glass carafe
is in place (see Stop ‘N Serve section).
