Just got my Heldor Rejuvenator brand tub up and running in a house I just moved into. Tub is about 15 years old, has not been run for at least 5 years, and no manual/directions were left from previous owner. Had someone install new pump and blower and got my chemicals from local supplier. Looking for some way to get information on the tub for general maintainence, tub size for proper chem applications, etc. Anyone out there have same or similar tub that can help? The local suppliers are of suprisingly little help...
