1.
Models shown at 230/460 Volts with side duct connections.
2.
Includes allowances for a wet evaporator coil, 1” filters and the heat exchangers. Refer to Table 12 for resistance values on appli-
cations other than gas / electric units with side duct airflows.

1.
Deduct these resistance values from the available external static pressure shown in Tables 10 and 11.
2.
The pressure through the economizer is greater for 100% outdoor air than for 100% return air. If the resistance of the return air
duct system is less than 0.25 IWG, the unit will deliver less CFM during full economizer operation.
3.
Add these resistance values to the available static resistance values on Tables 10 and 11.
