1. Safety precaution Warning・Caution Warning Never operate the unit in an atmosphere containing flammable or explosive gas Never operate the unit in an atmosphere containing flammable or explosive gas. Otherwise, an explosion or a fire may result since the unit is not explosion-proof. See section “13. - Page 7 1. Safety precautions Warning・Cautions Warning Do not adjust the reducing valve. The reducing valve has been set to the water sampling rate of about 1.0L/min(raw water pressure：3×100kPa, reducing valve pressure：0.6×100kPa)at the factory. Never attempt to readjust the reducing valve. If the factory setting of the valve is lost, water leak or reduction of flow may result. Be sure to release the pressure before exchanging consumable parts.
