Bosch 15 SEER2 Inverter Ducted Packaged Heat Pump - BTC 761701319 A (12.2022)
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 (Table 6) 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.

Table 7
Bold outlined areas represent airfl ow outside of the required 300-450
cfm/ton range.
1 Silent Mode --- low stage speed.
2 Factory Default --- low stage speed.
3 Silent Mode --- high stage speed. Or High Static Pressure Mode --- low stage speed.
4 Factory Default --- high stage speed.
5 High Static Pressure Mode --- high stage speed.
NOTES:
1. This table is only used to select the highest blower speed.
2. The rated airfl ow of systems without electric heater kits requires between
300 and 450 cubic feet of air per minute (CFM).The rated airfl ow of
systems with electric heater kits requires between 350 and 450 cubic feet
of air per minute (CFM).
3. The air distribution system has the greatest eff ect on airfl ow. Therefore, the
contractor should use only industry-recognized procedures.
4. Duct design and construction should be carefully done. System
performance can be lowered dramatically through poor design or
workmanship.
5. 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.
6. 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).
7. Factory Default maximum static pressure 0.6 inches W.C.. If static pressure
exceeds 0.6 inches W.C. please dial code to Tap(5)
For instructions on how to select fan speeds, refer to Section 6
of this manual.
