Installation Air Testing Refer to installation man ua Is for instructions. Hydrostatic test should be used instead of air or compressed NOTE:It is highly recommended that assembly training be conducted gas if possible. When air or compressed gas is used for testing, by a factory representative priorto installation start up, tremendous amounts of energy can be stored in the system. If a failure occurs, the energy may be released catastrophically, which When connecting containment pipeand fittings,plain ends ofthe can result in property damage and personal injury.
