11 Maintenance

11.1 Routine Maintenance

The HTK 1200N represents a mechanical precision 
instrument and thus has to be handled with particu-
lar care. The chamber is virtually maintenance-free. 
Always keep the chamber with the sample holder 
flange installed.

To guarantee trouble-free and reliable operation, 
please follow the hints below:

Remove the protective cap of the vacuum feed-
through only shortly before fitting the appropri-
ate connector.

Periodically remove residual sample material 
and clean the chamber.

Periodically check cooling water circuit.

Periodically check the thermocouple for proper 
functioning. If required, validate the temperature 
readout with an appropriate standard sample.

Make sure that the O-ring of the sample holder 
flange is always slightly coated with vacuum 
grease.
Periodically clean the O-Ring, the groove and 
the sealing surface with alcohol.

11.2 Check the Functioning of the Flow 
Controller

Check the proper functioning of the flow control-
ler once a week as described in chapter 5.7.

11.3 Exchanging of Parts

11.3.1 Switching off the Instrument

1. Switch off the CCU 1000 by using the power 

switch on the front side of the instrument.

2. Unplug all cables from the rear side of the 

instrument.

Perform the recommended maintenance work regu-
larly to ensure the smooth long-term operation of the 
instrument.

11.3.2 Replacing the Window Foil

The window in the housing is covered by either of 
the following foils:

When operating the HTK 1200N at tempera-
tures 

up to 1000 °C 

an aluminium-coated Kap-

ton foil of 125 µm thickness is used to cover the 
housing window. This foil guarantees minimum 
absorption.

For temperatures 

above 1000 °C

 a combination 

of a graphite foil and a non-coated Kapton foil of 
125 µm thickness is used.

To seal the window, the foil is pressed towards an 
O-ring using two clamps.

The combination of graphite foil and non-coated 
Kapton foil is mounted upon delivery.

To mount or exchange the window foil, proceed as 
follows:

1. Loosen the screws of the two clamps with the 

screw driver contained in the accessory box.

NOTICE

Risk of damage.

After long-term operation, we recommend clean-
ing both the O-ring and the groove using a lint-
free paper towel wetted with a suitable solvent, 
e.g. alcohol. After this, slightly cover the O-ring 
with vacuum grease (contained in the accessory 
box).

NOTICE

Risk of damage.

Do not operate the HTK 1200N chamber if the 
water flow controller does not work properly. 

NOTICE

Risk of damage

Above 1000 °C it is crucial to mount the combi-
nation of a graphite foil and a non-coated Kapton 
foil! The graphite foil protects the Kapton foil 
from any damage due to high temperature!

NOTICE

Risk of damage

Check the window foil regularly and exchange it, 
if it is leaky or foggy!
