Notes:
1.
Supply fan performance table includes internal resistance of rooftop. For total static pressure determination, system external static must be added to
appropriate component static pressure drops, (evaporator coil, filters, optional economizer, optional heating system, optional roof curb).
2.
The pressure drop from the supply fan to the space cannot exceed 2.25”.
3.
Maximum air flow for 27½ ton — 12,100 cfm, 30 ton — 13,200 cfm, 35 ton — 14,400 cfm.
4.
Maximum motor horsepower for 27½ ton — 10 hp, 30 ton — 10 hp, 35 ton — 15 hp.
