10.0 Bottle Refill
To refill the bottles proceed as follows:
- Fit the hose connector (
a
) to the tank valve (
b
)
- Screw in the fixing knob (
c
) until it is completely
tightened
- Check that the bleed valve (
f
) is closed by
rotating it clockwise
- Open the valve (
d
) by rotating it counter clockwise
- Open the valve (
e
) by rotating it counter clockwise
- Start the compressor by pressing the on button (
g
)
- When the refill has been completed the compressor
shuts down automatically
- Close valves (
d
) and (
e
) by rotating them clockwise
- Open the bleed valve (
f
) by rotating it counter clockwise
until all the residual air in the fitting has been expelled
- Unscrew the fixing knob (
c
) by rotating it counter clockwise
- Disconnect the bottle coupling.
Options for this compressor that may or may not be installed are:
•
Pressure Switch: Shuts down the compressor at a set pressure
•
Dial-A-Pressure Switch: Allows the operator to dial in a pressure for the compressor to
automatically shut off at when the pressure is reached during the filling process.
During refill the operator must be in the work area. It is advisable, during the bottle refill
phase, to submerge the bottles in cold water so as to reduce the drop in pressure that
accompanies cooling of the bottle.
During bottle refill those not involved in the refill procedure must maintain a safety distance of
at least 9 feet (3 meters). Also, it is forbidden to disconnect the hoses from the fittings or the
refill tap while the machine is under pressure.
Should bottles show evident signs of internal or external corrosion, do not refill them even if
they have been tested.
Use only tested bottles (as proven by a test stamp and/or certificate). The working and bottle
refill pressures are shown on the bottles themselves. It is forbidden to refill them at a pressure
greater than that indicated.
