Complete Compiled Specification.pdf - Peck Ormsby Construction

Locations: Install thermometers and thermometer wells at the following locations, and elsewhere as
indicated.
1. At the inlet and the outlet of each hydronic zone.
2. At the inlet and the outlet of each hydronic boiler and chiller.
3. At the inlet and the outlet of each hydronic coil in air handling units, and built-up central systems.
4. At the inlet and the outlet of each hydronic heat exchanger.
5. At the inlet and the outlet of each hydronic heat recovery unit.
6. At the inlet and the outlet of each thermal storage tank.
7. Thermometer Wells: Drill and tap pipes 5-inch and larger for installation of wells. Provide tees or
reinforced welding fittings on pipes smaller than 5-inch for installation of wells. Provide oversize
tees or enlarge pipe smaller than 3-inch at points where wells are installed to avoid restriction of
flow.
INSTALLATION OF PRESSURE GAUGES:
General: Install pressure gauges at locations shown on the drawing and where specified.
Locations: Install pressure gauges in the following locations, and elsewhere as indicated.
1. At the suction and the discharge of each pump.
2. At the discharge of each pressure reducing valve.
3. At the water service outlet.
4. At the inlet and the outlet of water-cooled condensers and refrigerant cooled chillers.
Pressure Gauge Cocks: Provide stem mounted pressure gauges with T-handle cocks and pressure
snubbers.
INSTALLATION OF FLOW METERS:
General: Install flow meters at locations shown on the drawings and where specified. Install in accordance
with ASME recommendations for flow meters.
Locations: Install flow meters in the following locations, and elsewhere as indicated.
1. At the discharge of each pump.
2. At the inlet of each hydronic coil in built-up central systems.
Piping: Install piping in the exact locations and arrangement, both upstream and downstream of primary
elements, as required by the manufacturer's published literature. Provide any necessary piping changes
required for certification without additional cost.
Horizontal Pipe: Provide the connection nipples at, or slightly above, the horizontal centerline of the pipe to
minimize the entrance of gases and impurities when flow is measured in horizontal pipe.
Taps: Provide taps with shut-off valves and quick connecting hose fittings for portable meters or
double-ferrule compression fittings for connection to tubing for permanently located meters or recorders.
