I purchased a new home with an older CL17 (over 20 years)...which still works well. However...the previous owner did not have an owner’s manual. I contacted Schulz Heating and Cooling and Jon interceded with the manufacturer for me...and an owner’s manual was mailed to my address within a couple of days. In addition...there was no charge for that service. It doesn’t get much better than that. Thanks for great customer service...I would definitely rate this company as an A+ V. Kirby Bahr
