Two of these air handlers mounted up about 20 feet in a open gym area.
We have to rent a high lift about every 3 months to service.
The blower belt usually is loose and squealing by the time we can get to it.
We have aligned the pulleys and replaced the worn motor sheaves.
I do not like the A50 belt! I wish to change the pulleys to a B size, hoping to get longer belt life.
Has anyone out their had this problem and a good solution?
Has anyone tried to put a spring loaded auto tension setup on these air handlers.? I saw a few auto belt tensioners in the Grainger catalog I thought about attempting to customize to fit.
