There are two ways to replace the transducer tank:
Replacement by a complete transducer tank with mounted
transducer system (and heating, if required). We recommend to
use a complete tank if the transducer system is damaged and if
you do not have the necessary know-how for a replacement of
piezoceramics.
Replacement by a preassembled tank with coupling piece(s)
and the support for the heating element(s), but without
transducer system. We recommend to use the preassembled
tank if the transducer system on the old tank is without fault and
can be mounted on the new tank. For this you need a torque
wrench. We recommend to carry out this repair only if you have
the required know-how for replacing piezoceramics.
For instructions on the replacement of the transducer system
and / or of the piezoceramics please
see section 14
.
See spare parts list for the required unit type and voltage.
1. Place the unit upside down on a solid workplace.
2. Open the unit as described in
section 6
.
3. On units with heating: Interrupt the electric supply cables to
the heating(s) and separate the temperature sensor from
the unit.
Caution! Mark all electric cables to avoid interchanging
when you assemble the unit: risk of damage.
4.
On units with drain duct: Loosen the screw connections of
the drain duct. Note: The screw connections are secured
with Loctite 586. The screw connections can be loosened
more easily after heating the duct in the threaded area with
a hot air fan (
see section 16
)
.
5. Remove the transducer tank from the housing:
Carefully heat the tank edge around the sealing e.g. with a
hot air fan to make the sealing material flexible (
see
illustration 15.3.A
).
Caution!
The handles can be damaged
by hot temperatures.
6. Cut the sealing between the tank edge and the housing with
a narrow and flexible knife (
see illustration 15.4.A.
).
7. Carefully lever the tank out of the housing; cut the sealing
further with the knife if necessary; use the knife to loosen
the tank from the housing (
see illustration 15.4.B
).
8. Remove the remains of the sealing at the transducer tank
and the housing edge with a knife.
9. Degrease and clean the glueing surfaces of the housing
edge of the (new) tank with alcohol.
10. Fill new sealing material (e.g.Teroson) evenly elong the
edge of the transducer tank.
