Ken,

The manual is NOT wrote to accommodate the industry accepted protocol for fans. 
 Labels are not an accepted standard for direction of air flow.  The industry 
standard is arrows embedded in the case of the fan indicating the direction of 
rotation and air movement.  The manual doesn't tell me which way the air should 
flow.  My K2 has the fan label on the outside but airflow is inward.  Yes, it 
is assembled per the manual and verified at least twice.

Perhaps I should have been more clear on my description of my conception of the 
instructions in the KPA3 assembly manual.

On the contrary, the ASSEMBLY manual is very clear on
how they should be installed.



They should blow out . . . as stated in the manual:



Assembling the Fan Panel

Locate the fan panel and mount the fans as shown in Figures 12 and 13
using 4-40 7/8” black flat head

screws and acorn nuts. Note that the appearance of the fans in your kit
may differ slightly from those shown.

1. Orient the fans with the side with the manufacturer’s label facing
away from the panel.

  Hi Folks,

Which way is the air flow supposed to be through the fans on the K3?  Mine 
blows out, pulling air in from the slots in the top above the KPA3.  (My K2 
blows in.)  The manual doesn't seem real clear on which way to install them in 
the K3.
