Where generators are not used throughout the entire year always remove
all water and gas and clean thoroughly at the end of the season during
which they are in service.
It is usually necessary to take the bell portion out and invert it so as
to allow all gas to escape. This should never be done in the presence of
artificial light or fire of any kind.
Always observe a regular time, during daylight hours only, for attending
to and charging the apparatus.
In charging the generating chambers of water-feed machines clean all
residuum carefully from the containers and remove it at once from the
building. Separate from the mass any unslacked carbide remaining and
return it to the containers, adding now carbide as required. Be careful
never to fill the containers over the specified mark, as it is important
to allow for the swelling of the carbide when it comes in contact with
water. The proper action and economy of the machine are dependent on the
arrangement and amount of carbide placed in the generator. Carefully
guard against the escape of gas.
Whenever recharging with carbide always replenish the water-supply.
Never deposit residuum or exhausted material from water-feed machines in
sewer-pipes or near inflammable material.
