LEGEND
No./TR
— Charge to unit capacity ratio, lb per ton (at 45°F SST, 95°F OAT)
Cap Red
— Capacity reduction caused by suction line pressure drop > 2°F
Liquid PD (F)
— Liquid line pressure drop, saturated temperature, °F
Max Lift
— Maximum liquid lift (Indoor unit ABOVE outdoor unit only), at maximum permitted pressure drop.
Max Lift PD (F)
— Pressure drop including Maximum liquid lift value
SC
— Sub-cooling, °F (at liquid line valve)
Suction Line PD (F) — Suction line pressure drop, saturated temperature, °F
TC
— Total Capacity, MBH (at 45°F Saturated suction, 95°F outdoor air temperature)
