Uncertain if system was still working or had been isolated. Broken glass is lying inside and at bottom end of ICS unit body. Inner Teflon film is still intact.
Exterior insulation is developing large cracks due to long term deterioration.
Butted ends of insulation have separated and piping is exposed.
Excellent collector mounting. Still secure and sealant is flexible.
Stopped again later that month. No one home. Left note and card on door.
