WARNING
To lower the pressure of the coffee dispensing
circuit close the pump input tap and depres-
surize the circuit activating the delivery from
the units for a few seconds.
WHEN TO INSPECT CONNECTIONS
Because of the hardness of the water it is possi-
ble that over time the limestone will stratify close
to the joint, so it is advisable to check that the
water flows freely.
1 To remove the connections remove the
back panel of the machine. To facilitate the
replacement it may be helpful to remove the
side walls as well. Using a Phillips screwdriv-
er, unscrew the screws and carefully remove
the panels.
2 Using a 12mm wrench to disconnect the
Teflon tubing.
In newer versions of the machine use a No. 17
key to unscrew the copper pipe.
The fitting is conical therefore it does not need
Teflon or sealants.
