DESCRIPTION: The Remote Arming Valve is designed to quickly turn the supply of nitrous oxide "on" or "off" without having to turn the bottle
valve on/off every time. When the nitrous system will not be used in the immediate future (such as overnight non-usage) , both the remote arming
valve, as well as the main bottle valve, should be turned to the "off" position.
1. Be sure the nitrous bottle is turned to the "off" position. Also
make sure the ignition key is in the "off" position, and the
negative cable on the vehicle's battery has been disconnected.
2. Relieve any pressure in the existing nitrous line by slowly
loosening the main line fitting from the bottle.
IMPORTANT NOTE: Nitrous Oxide can be lethal and must be
respected. Be sure you are located in a well ventilated
area. Remove your hands from the fitting while the
nitrous oxide is venting, and avoid breathing the escaping
nitrous.
