Abstract
A refrigerant recovery/loading manifold for air-conditioning equipment has a manifold body and valves for opening and closing a passage inside the manifold body, the passages including a high-pressure-side passage, a low-pressure-side passage, a recovery-side passage, a vacuum-suction-side passage, a purging passage, and a common passage via which these passages communicate, at least a high-pressure-side valve being provided to the high-pressure-side valve being provided to the high-pressure-side passage, and at least a low-pressure-side valve being provided to the low-pressure-side passage; wherein a high-pressure connection means is provided to the low-pressure-side passage, the high-pressure connection means having a valve mechanism and being able to connect with a high-pressure-side quick joint.
