codes and regulations. Incorrect installation could cause leaks, electric shock, fire, or an explosion. In areas
where Seismic Performance requirements are specified, the appropriate measures should be taken during
installation to guard against possible damage or injury that might occur in an earthquake. If the unit is not

way, a serious accident can occur. Never bypass, wire around, or jump-out any safety device or switch.
