6.2 Assembly
Step 1:
Mount the open system across the diameter of
the machine and provisionally fix in place with
side mounting braces. Close the heat-cool
segments and screw the clamping screws of the
cup spring caps on these segments to the lower
heat-cool segments.
CAUTION: Ensure a positive-locking construction and an
even clamping gap on the heat-cool segments!
Step 2:
Tighten the clamping screws to a torque of
8.5 Nm and the clamping screws with cup
springs to 20 Nm (when cold). The expansion
compensation required at operating state tem-
perature to maintain functionality must be ensu-
red. In the case of heater bands with clamping
screws, the heating systems must be retigh-
tened during the first heating-up period to ensu-
re that the heating systems are sitting correctly
in relation to the metal insert to be heated.
Step 3:
Place outer shell of cooling jacket in place and
screw down.
Ready for connection!
Heating systems may be destroyed by overheating if they
are not connected with a positive-locking fit.
It must be generally ensured that no mechanical damage
can be caused by external impacts, such as moving parts.
7. Operating conditions
7.1 Temperatures
The connecting lines must be protected against tempera-
ture effects or be designed to withstand them.
7.1.1 Temperature control
Heating systems can absorb moisture during storage or
storage in the wrong conditions, so they must be fitted with
temperature control with start-up circuitry.
7.2 Protection against accidental contact, dust and
moisture
The heating systems must be protected against contact,
dust and moisture according to the ambient conditions.
During operation, it is particularly important to prevent the
ingress of any foreign matter such as oil, water, plastic etc.
7.3 Storage
If storing for a prolonged period of time (several months), it
must be ensured through measures within the system that
the insulation resistance will drop.
Heating systems must not be commissioned until it has
been ensured that the insulation resistance is
≥
1 MOhm.
Note:
We recommend that heating systems are stored in a dry
environment and that a suitable desiccant is added as
appropriate.
7.4 Disposal
Disposal must be carried out in accordance with statutory
regulations.
