Airfl Ow Performance - Bosch BVA 2.0 Series Installation Instructions Manual

Installation Instructions
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

Table 7
Bold 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).
