Pressure Switches
Figure 10 displays the proper routing
of pressure switch tubing for *TA & *TK
furnaces. On both furnaces, the tubing
connects at one end of the pressure
switch and is routed directly to the
static tap on the inducer assembly.
NOTE:
The control board in the *TA
illustration has been omitted for clarity
of tubing installation. There is no need
to remove the control board to install
your pressure switch tube.
