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.
