4.5 Installation
4.5.1
Decalcifi cator resin washing where it is installed as
accessory
First of all fi ll the distributor’s water circuit, it is advisable effect
the water softener resin regeneration (if installed)
operating in the following manner:
– insert the pipe of the bottom faucet in a container suitable for
this use
– open the faucet (Fig.4.13)
– insert the key in the door switch (Fig.4.12)
– Let the water fl ow until it is clear (Fig. 4.14).
– Take out the key and close the faucet.
BMV972 assembles as standard the Brita fi lter with Acquaquell
cartridge 1.5 and does not provide for the above mentioned
procedure application. In this case, just link DA to the mains and
proceed with the hydraulic circuit fi lling.
4.5.2 Filling of water circuit
INSTALLATION PROCEDURE
The installation procedure is valid only for the single boiler distri-
butors. In particular, expresso boiler and polisulphone boiler fi tted
with level probes.
EXPRESSO SINGLE BOILER
At the line output, the distributor will be put in condition of FIRST
INSTALLATION. As soon as it reaches the location, the operator
will link only water (both in case of water supply connection and
autonomous tank) and the mains.
The distributor will automatically require water until micro lack of
water reaches N.C. for at least 15 seconds. In this condition D.A.
switches on the pump and, with resistance OFF, will supply 200
cc of water (measured through the fan). Following this procedure
the distributor installation date is stored. Once the date has been
confi rmed, D.A. waits 10 seconds and soon after it will start to
heat water in the boiler.
POLISULPHONE BOILER with LEVEL PROBES
At the output of BV lines the distributor will be put in condition of
FIRST INSTALLATION. As soon it reaches the location the operator
will link only water (both in case of water supply connection and
autonomous tank) and the mains.
The distributor will automatically require water until the maximum
level probes detect the presence of water. After this procedure
the distributor installation date is stored. Once the date has been
confi rmed, D.A. waits 10 sec and soon after it will start to heat
up water in the boiler.
SINGLE STAINLESS STEEL BOILER FOR SOUPS
At the output of BV lines, the distributor will be put in condition
of FIRST INSTALLATION.
As soon it reaches the location the operator will link only water
(both in case of water supply connection and autonomous tank)
and the mains.
The distributor , in condition of OFF resistance, will automatically
require water and will open the electrovalve 2 to vent air which
is in the boiler.
This condition will last 200 seconds. At the end of this timeout,
the distributor will close the electrovalve 2 and the input water
ev for 20 sec. After this period, the water loading will last until
the micro lack of water is N.C. for a time exceeding 5 sec (this
operation is linked to a second timeout of 200 seconds). In this
condition D.A. automatically activates the electrovalve 2 which
will supply 20 s of water.
At the end of the supply, the micro lack of water returns become
N.C. After this procedure the distributor installation date is stored.
When the date is confi rmed, D.A. waits 10 seconds and soon after
it will start to heat up water in boilers.
DOUBLE BOILER
At the output of the lines, the distributor will be put in condition
of FIRST INSTALLATION. As it reaches the location the operator
will link only water (both in the case of linking to the mains and
autonomous tanker) and the mains.
The distributor, in condition of resistances OFF, will automatically
require water and will open the electrovalve 2 to vent the air which
is in the stainless boiler.
This condition will last 200 seconds. At the end of this timeout,
the distributor will close the electrovalve 2 and the water input
ev for 20 sec.
After this time water loading will continue until the micro lack of
water is N.C. for a time exceeding 5 sec (this operation is linked
to a second timeout of 200 seconds). In this condition the D.A.
activates the electrovalve 2 and will supply 20 sec of water.
At the end of the supply, the micro lack shall return to N.C. After
10 sec D.A. activates the expresso pump, and, on condition of
resistance OFF, it will supply 20 cc of water through the coffee ev
(measured through the fan).
After this procedure, the distributor installation date is stored.
When the date is confi rmed, D.A. waits 10 seconds and soon after
it will start to heat up water in the 2 boilers.
