Check for presence of asbestos-containing materials (ACMs) | Potential ACMs will be handled in accordance with SWS 2.0110.2 Potential Asbestos-Containing Materials | Ensure a safe work environment |
| 5.3103.7b
Location of pressure gauges | Available plans will be reviewed to assess system design and intent Pressure gauge locations and conditions will be visually verified; pressure gauges should be located on the inlet and outlet of all flow dependent devices (e.g., boilers, pumps, strainers, heat exchangers, coils, control valves) | Determine minimum pressure gauge placement |
| 5.3103.7c
Select appropriate pressure gauges | Pressure gauge range will be selected to ensure accurate readings over system operating range For high-rise applications where pressure differential is a small percentage of gauge pressure range, differential pressure gauges will be used | Ensure selected pressure gauge provides accurate pressure measurement |
| 5.3103.7d
Install pressure gauge | Nearest valves on either side of pressure gauge location will be closed Pressure gauge will be installed in accordance with manufacturer specifications Measurement accuracy of differential pressure applications (e.g., pumps, strainers, heat exchangers, valves) will be improved when a single-pressure gauge is connected to both inlet and outlet of device with appropriate valving System will be refilled and air will be eliminated | Properly install pressure gauge |
