5.3.4 Using an extension hose for a sniffer tip
To get into hard-to-reach areas, attach an extension hose to the sniffer tip, see "10.1 Ac-
cessories and spare parts", page 67 .
Fig. 7: Attach the extension hose
If it is necessary to shorten the extension hose, cut off the end of the extension hose that
you use to sniff the test object at an angle of about 45°.
1 To attach the extension hose to the sniffer tip, screw the adapter from the set with the
extension hose to the filter holder at the end of the sniffer tip.

Make sure that the short extension hose at the end of the adapter encloses the filter
holder.
2 Insert the extension hose into the rear opening of the adapter.

The extension hose is automatically locked into position.
3 To connect the extension hose to the calibration opening for internal calibration for the
COOL-Check, insert the centering ring into the calibration opening on the device to
make the COOL-Check opening smaller.
Disassembly ► To remove the extension hose press the release ring in the direction of the adapter so
that the locking device releases and thus enables the extension hose to be removed.
5.4 Insert or replace a COOL-Check calibration leak
A built-in calibration leak (COOL-Check) and various external calibration leak devices are
available as accessories for the device,
see "10.1 Accessories and spare parts", page 67 .
No COOL-Check is available for the R744 (CO
2
) and R600a/R290 gases. Solely calibrate the
sniffer line for the R744 and R600a/R290 gas using external calibration leaks.
