Airfl Ow Performance - Bosch 19 SEER Series Operation Manual

Installation & Operation Manual
5 Airfl ow Performance
Airfl ow performance data is based on cooling performance with a coil and
no fi lter in place. Check the performance table for appropriate unit size
selection.
External static pressure should stay within the minimum and maximum
limits shown in the table below in order to ensure proper operation of
both cooling, heating, and electric heating operation.

B old outlined areas represent airfl ow outside of the required 300-450 cfm/ton
range.
NOTES:
1. The high stage airfl ow must be used as the rated airfl ow for the full load
operation of machine.
2. The rated airfl ow of systems without electric heater kits requires between
300 and 450 cubic feet of air per minute (CFM).
3. The rated airfl ow of systems with electric heater kits requires between 350
and 450 cubic feet of air per minute (CFM).
4. The air distribution system has the greatest eff ect on airfl ow. Therefore, the
contractor should use only industry-recognized procedures.
5. Duct design and construction should be carefully done. System
performance can be lowered dramatically through poor design or
workmanship.
6. Air supplier ducts should be located along the perimeter of the conditioned
space and properly sized. Improper location or insuffi cient air fl ow may
cause drafts or noise in the ductwork.
7. Installers should balance the air distribution system to ensure proper quiet
airfl ow to all rooms in the home. An air velocity meter or airfl ow hood can be
used to balance and verify branch and system airfl ow (CFM).
