Commissioning • Use Service form 1A • Proof of performance • Speeds up Tech support • Reduces recalls
Balancing Orifices • Works with all plenums • 15, 35, 50% • Easy to re-balance system
Airflow Checks • U tube or Slope Gauge – best way • Delta T in cooling 25-28 deg. • Electric Heat Delta T check • Motor Amperage
Electric Heat Airflow • Convert KW to BTU (3413 X KW = BTU) • DeRate for 208 (.8) • Cfm’s x1.08 x’s Temp. Diff. = BTU • Compare to unit data
Winterizing Cooling Only Units • Winter supply shut-offs • Seal the return • Winterize condensate • Shut off breaker
