Replacing The Elastomeric Adapter - aquatechnik BBR 90 Instrucciones De Uso

3) Insert the pipe into the mechanical expander (G) pushing it up to the stop.
Warning: The pipe must be in axis and parallel to the expander.
4) Press the starting button (B-2) for 2-3 seconds: the cycle will automatically continue.
The belling time varies from 6 to 8 seconds. When the cycle has finished, the pipe
will be automatically released from the tool once such operation is over.
NB: The mechanical expander (G) has anti-slide teeth. When performing belling (expansion of
pipe), a minimum shortening of bell occurs. This does not alter the proper bell length.
Warning: Once the coupling cycle is over, the equipment goes back to its initial position,
ready to perform the next working cycle. Otherwise, press the emergency stop button
(B-1).
5) Clutch the
NB: All
using aquatechnik grease is recommended (Item# 71391).
6) Screw the cap up to the anti-unscrewing safety notch (use the special wrench series
50600).
NB: The connection may be disassembled by unlocking the cap by means of the special
wrench. DO NOT RE-USE caps already locked.
7) In order to change pipe diameter, unscrew the mechanical expander (G) and set the
one with the desired diameter, following the steps described in section 1.
8) When you put the coupling tool BBR 90 in its case, be sure that the conical pin is
back into return position.

Replacing the elastomeric adapter

The elastomeric adapter (H) must be replaced only when it has evident signs of tearing (cuts or
breaks).To replace it, just follow the specified instructions and use the suitable tools.
8.1 Replacing the elastomeric adapter from ø 14 to 32 mm:
use of the splitting wrench (art. 50830)
1) Completely introduce the elastomeric adapter into
the tips of the splitting wrench following its coning
(picture 8).
2) Open the splitting wrench slowly and press hard and
repeatedly pausing a few seconds at each opening.
Repeat the operation several times rotating the elasto-
meric adapter (picture 9) in order to obtain a uniform
expansion.
3) Set the splitting wrench at rest. Take the expanded
elastomeric adapter and introduce it - rapidly and
following its coning- into the mechanical expander by
pushing it flush with the same expander. In order to
make this operation easier, use a plastic-head ham-
mer.
NB: Make sure that the elastomeric adapter and the
mechanical expander have the same diameter (see the
diameter-colour correspondence in the table).
connection into the coupling obtained by pushing it up to the stop.
connections are prelubricated. If lubricant is lacking or connection is re-used,
