Product Overview
Lennox 603364-36, Blower Proving Switch Kit For LG/LC/LH/LD 024-300 Series Units
The Blower Proving Switch Kit is used on LG/LC/LH/LD 024-300(S) (3 to 25 ton) units.
The normally open S52 air flow (blower proving) switch will close with an increase in static pressure when the blower is started.
Units which contain a Unit Controller will keep the heating and cooling functions locked out and also show an alarm in the system if the blower is not sensed. S52 is found on the “C” or control wiring diagram section in the unit.
Includes:
- Air flow switch (S52)
- Air flow fitting
- Air flow tubing
- 2- Screws
