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 |
| 5.3103.1b
Determine locations for balancing valves | Prior to installation of balancing devices, the distribution will be cleaned of any debris that can clog the new devices Available plans will be reviewed to assess system design and intent Balancing valve location and condition will be visually verified; valves should be located on all distribution loops and critical flow dependent devices (e.g., boilers, air handlers, heat exchangers, fan coils, etc.) | Determine current configuration |
| 5.3103.1c
Evaluate balancing options | Use of automatic vs. manual balancing valves will be evaluated in terms of life cycle cost (installation labor, hardware, labor to balance, and impact on energy consumption) | Determine a balancing strategy that ensures balancing throughout peak heating and shoulder seasons |
| 5.3103.1d
Isolate balance valve location | Nearest valves on either side of valve location will be closed | Eliminate water supply to valve location |
| 5.3103.1e
Repair and/or install balance valve | Functionality of balance valve will be assessed and repaired/replaced if necessary New balance valves will be installed on all distribution loops and critical flow dependent devices (e.g., boilers, air handlers, heat exchangers, fan coils) System will be refilled and air will be eliminated | Install valves in appropriate locations |
| 5.3103.1f
Set balance valve | Valve will be adjusted to match device specification Water flow will be measured in accordance with
