5) DuctworkPreparation
1) Duct ESP:
To determine your system's indoorexternal static pressure
(ESE in inches of water) use a duct calculator (as provided
by your duct supplier). Include all flex duct transitions and
discharge grille(s). If flex duct is used, be sure all the slack
is pulled out of the flex duct. Flex duct ESP can increase
considerably when not fully extended. DO NOT EXCEED a
total of .30 ESP,as this isthe MAXIMUM design limit for the
VERT-I-PAK A-Series unit.
2) Determining the Indoor CFM: Chart A - CFM
18000 12000/9000
.00 520 420
.10 510 410
.20 500 370
30 490 330
3) Correct CFM (if needed):
Chart B- Correction Multipliers
230V 1.00
208V 0.97
Heating 1.00
Cooling 0.95
6) ChassisInstallation
