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 drops from the supply fan to the space should not exceed 2.25” (558.8 Pa) positive.
3.
Maximum air flow 23 ton (80 kW) is 4756 L/s, 25 ton is 5190 L/s, 29 ton is 5663 L/s
4.
Maximum motor kW for 23 ton unit is 7.5 (10 hp), 25 ton is 7.5 kW (10 hp), 29 ton is 11.2 kW (15 hp).
