SAFETY PRECAUTIONS
5.1
CALORIMETER (3K-F)
•
Connect the safety earth to the EARTH STUD on the back of the instrument. This is required
when the external power supply fails
•
Do not open the CAL3K for any reason whatsoever! There are no serviceable parts inside the
unit.
DO NOT TAMPER WITH THE EARTHING - CONSULT A QUALIFIED ELECTRICIAN SO THAT THE
EARTHING CAN BE CHECKED.
5.2
FILLING STATION (3K-3)
•
Install the flexible high-pressure pipe supplied without any sharp bends.
•
Check the nylon high-pressure pipe supplied for any mechanical damage before putting it under
pressure.
•
Secure the pipe into the quick connector and screw the connector to the pressure regulator side.
Secure the pipe nuts to the pressure regulator side, then clamp the ferrule to the high pressure
pipe on the gauge block side.
•
If the oxygen bottle is not situated close to the Filling Station or if it is in another room or perhaps
outside, then a solid, permanent installation of pressure piping should be installed, as well as a
shut off valve and pressure gauge within easy reach of the 3K-3 Filling Station.
•
If bottled oxygen is used, a suitable High Pressure oxygen regulator must be supplied by your
Agent, or sourced locally. Ordering this item from the factory ensures that the necessary
modifications have been made to fit the 3K-3 Filling Station.
•
The oxygen bottle should be secured according to regulations.
•
Secure the pipe to the side of the filling through the supplied device
•
Do not use any oil or grease on any of the oxygen fittings or the O-rings. A very small amount of
high-pressure (vacuum) grease is allowed on the O-ring to make them pliable. Wipe them clean
afterwards.
•
•
DO NOT USE ANY OTHER PIPE OTHER THAN THE HIGH PRESSURE PIPE SUPPLIED FOR OXYGEN
FILLING.
•
DO NOT USE THE HIGH PRESSURE PIPE IF IT HAS A SHARP BEND OR KINK, DISCARD
IMMEDIATELY
•
ALWAYS FILL THE VESSEL WITH OXYGEN TO A MAXIMUM PRESSURE OF 3000KPA (30
bar).
