2. Safety
Protective gloves
Based on the gas properties, it is possible that the gas, due to the quick
expansion, gets very cold if the cylinder is opened very quickly.
Wear protective gloves to protect from freezing.
If, with an operator risk analysis, contaminated gases should be detected, for
any subsequent maintenance operations, protective measures appropriate to the
contamination should be taken.
Respirator
For maintenance work, the respirator must correspond to the protection
level specified for the corresponding gas in the material safety data sheet.
Protective suit
For maintenance operations, specific protective clothing must be worn

General safety instructions
Contents of the general safety instructions
This chapter deals with the general safety in the handling of SF
6
gas and the SF6 gas
lling cart. The safety instructions relevant for the task can be found at the start of the
respective chapters (e.g. transport, commissioning, ...) and must be followed.
Handling SF₆ gas
SF₆ gas is a greenhouse gas which is listed in the Kyoto Protocol. SF6 gas must not be
released into the atmosphere, but must be collected in suitable containers.
Properties of SF6 gas
■
Colourless and odourless
■
Chemically neutral
■
Inert
■
Not flammable
■
Five times heavier than air
■
Non-toxic
■
No damage to the ozone layer
Detailed information is given in IEC 60376 and IEC 61634.
Risk of asphyxiation through SF6 gas
High concentrations of SF₆ gas can lead to asphyxiation, since breathable air is
displaced from the lungs with the inhalation of SF₆ gas.Since SF₆ gas is heavier than air,
it collects, especially, at ground level or lower-lying rooms below the reference level (e.g.
cellars). This is particularly dangerous since SF6 gas is colourless and odourless and
thus may be imperceptable to people.

It is recommended to use original accessories and original spare parts from WIKA.
Using accessories and spare parts from third parties can lead to damage to the
instrument or accidents, due to quality defects or other reasons.WIKA assumes no
liability for damage or accidents caused by a malfunction or unsuitability of accessories
and spare parts which do not originate from WIKA (e.g. unsealed connecting parts). No
guarantee claims can be made which arise due to a malfunction or unsuitability of any
accessory or spare part from a third party.
Danger of tripping due to improper installation of connections
Improperly installed connections such as cables, hoses or pipelines can create tripping
hazards, and can cause serious injury.
Route the connections so that no tripping sources are present. Mark unavoidable
tripping sources with yellow and black marker tape.
2.8 Residual risks
What are residual risks?
The instrument has been designed so that no personnel are exposed to preventable
risks. Particular hazard points are protected through specific protective systems.

4. Design and function
4. Design and function
4.1 Description
The GFU08 series of robust and modular gas cylinder transport carts are used for
the lling and relling of SF
6
gas in the required gas compartment. The modular
design enables worldwide application through the various mechanical and electrical
connections.
The model range is split into 4 versions:
■
Model GFU08-B: Filling cart
■
Model GFU08-W: Filling cart with scales
■
Model GFU08-E: Filling cart with vacuum pump
■
Model GFU08-C: Filling cart with scales and vacuum pump
Models GFU08-E and GFU08-C are tted with vacuum pumps. With these, the air is
extracted from the SF
6
gas compartments so that, afterwards, a professional SF6 gas
lling can be made. The 10 m³/h vacuum pump, built into the models GFU08-E and
GFU08-C as standard, enables a fast evacuation down to < 0.02 mbar (0.015 Torr).
For larger volumes, suction of up to 40 m³/h is available as an option. With 2-stage
pumps, the nal pressure can be reduced as far as 2 x 10
-3
mbar. The risk of either
too high humidity or air concentration in the SF
6
gas compartment is therefore not a
consideration.With the models GFU08-W and GFU08-C, gas cylinder scales are built
in, which enable the exact determination of the amount of SF
6
gas lled. Thus, the SF6
gas lling cart is an ideal tool for using the mass-balance method in accordance with the
IPCC directive for the preparation of emission reports.The special, at design of the load
cell under the gas cylinder allows easy loading and unloading of the heavy cylinder by
only one person.

6. Commissioning, operation
6.2 Commissioning the vacuum pump (models GFU08-E and GFU08-C)
The vacuum pump is delivered ex works without oil lling. Thus, before the rst start-up
of the vacuum pump, it should be lled with the accompanying oil. By unscrewing the oil
mist separator, the accompanying oil can be lled up to the height of the “middle sight
glass” in the vacuum pump which must be standing on the level.
The oil level must not lled beyond the “middle sight glass”. After lling the
oil, screw the oil mist separator back in.
To start the pump, the suction pipe must be opened. For this, remove the
cap (in addition, turn the stopcock to the setting “Flow”).
6.3 Evacuation of a gas compartment before filling it with SF
6
gas (models
GFU08-E and GFU08-C with vacuum pump)
■
Before switching on the vacuum pump, connect the vacuum suction hose to the
gas compartment and make sure that the connection is gas-tight and without leaks.
The gas compartment, lled with air, must not have a higher pressure than the
atmosphere.
■
In accordance with the operating instructions included from the manufacturer, the
vacuum pump must be operationally safe (oil level, power supply).
■
After switching on the vacuum pump, the pressure display will show the negative
pressure range smaller than 0 bar after a few seconds. If the pressure does not drop
below 0 bar, the vacuum pump must be switched o immediately.
→ See chapter 10 “Faults” for this.
■
Seal the gas compartment after the required nal pressure has been reached or after
the required pump-o time and make sure that it is gas-tight. Afterwards, switch the
vacuum pump o.
■
After switching o the vacuum pump, there should be no vacuum over a longer
period at the suction joint of the vacuum pump. Dismount the vacuum hose and
ventilate it.
6.4 Preparation of the SF
6
gas filling
6.4.1 Mounting the gas cylinder
CAUTION!
Use only appropriate adapters for the cylinder types to be connected! Risk
of accidents if unsuitable adapters are used.
■
After a successful evacuation, the gas outlet on the SF6 gas cylinder can be
connected properly and without leakage to the connecting hose of the gas cylinder
on the SF
6
gas lling cart by means of an adapter.

6. Commissioning, operation
■
Protect the gas cylinder valve by an appropriate valve protection.
■
To test the leak tightness, a model GIR-10 leak detector or a comparable leak
detector must be used.
■
Close the outlet valve at the pressure reducer.
■
After opening the gas cylinder valve, the initial pressure is available at the pressure
reducer.
6.5 Filling and refilling of SF

gas
6.5.1 Connecting the filling hose
Establish a gas-tight connection between the SF
6
gas lling cart and the gas
compartment to be lled using the lling hose included.
6.5.2 Adjusting the pressure reducer
Use the pressure setting handle to set the pressure reducer to the desired output
pressure. For this, read the pressure on the output pressure gauge.
6.5.3 Weighing the quantity of the filled SF
6
gas (models GFU08-W and GFU08-C
with scales)
CAUTION!
Place the gas cylinder without the shunt forces of the fastening elements
(ratchet strap or chain) on the scale plate.
Secure the gas cylinder against falling over!
Place the SF

6.5.4 SF6 gas flows into the gas compartment
CAUTION!
Wear suitable gloves to protect your hands against frostbite.
■
Slowly open the outlet valve on the pressure reducer so that the SF6 gas can ow into
the gas compartment provided for this. Based on the gas properties, it is possible
that the gas, due to the quick expansion, gets very cold if the cylinder is opened very
quickly.
■
Fill the gas compartment according to the lling parameters indicated by the
manufacturer. Use suitable measuring devices.
■
Remove the lling hose from the gas compartment after having reached the lling
parameters.
6.5.5 Reading the filled gas quantity (models GFU08-W and GFU08-C with scales)
After the lling process, the quantity lled into the gas compartment is displayed with
negative sign on the digital display of the scales.
The MODE button can be used to switch between the complete weight and the TARE
weight (GROSS/NET).
