Cautions for Installation
■ Install at a stable place of sufficient strength.
Please note that there might be some places not
strong enough to install due the structure of
building.
■Do not install in locations where harmful or
corrosive gasses may be present (i.e. acidic,
alkali, organic solvent, paint gasses etc. from
machinery or factories)
Installation in such a location could cause a
gas-poisoning and a fire.
Prohibited
