Water System Preparation
• Water connection options:
–
Sweat, Threaded, Push Connect.
• Before connecting beams to the water system,
flush and drain the water main piping to remove
contaminants from the construction process.
• Pressure test the water system for
leaks. Isolate and fix leaks.
Water Balancing - Manual
• Adjust balancing valves based on fluid flow rates
scheduled on Price performance data.
Water Balancing - Auto/Pressure Independent
• Ensure correct pressure independent valves are
installed based on design drawings. Confirm the
correct flow rate is on the correct branch. (i.e. hot
waterflow rate going through hot water coil.)
Air System Preparation
• Ensure an air tight connection between the supply duct
and the active beam. Duct connections are recommended
to meet SMACNA class B standard up to 2 in. w.g.
• Air connections will ideally have straight duct sections
upstream of the air inlet. Although bends in the duct
are permitted close to the air inlet, there should be
3 duct diameters straight leading into inlet to ensure
laminar flow only straight ductwork connections
will yield a reliable pressure port measurement.
Air Balancing
• Measure static pressure in the plenum of the
active beam by connecting a static pressure
measurement device to the port included on the
beam. The pressure port is located inside the
discharge slot, near the end of the beam.
• Adjust balancing damper to match the Price project
schedule static pressure to the measured result.
• Damper should be used for trimming only.
• Contact the Price Application Engineering
department for high altitude locations.
• See Air flow calibration charts on pg 9. Chilled
beams should be balanced based on active
length of water coil, not casing size.
NOTE:
Traversing the duct work before a beam will not
guarantee that the beam is properly balanced because
performance is based on internal plenum pressure.
