 IX. Trouble-Shooting 

 

Each Kooltronic Air Conditioner is engineered for performance and built for reliability. They are designed to 
require no routine maintenance other than the cleaning of ambient air filters. If your air conditioner 
should require warranty service, please contact Kooltronic. If you require service out of warranty, 
we have compiled a trouble-shooting chart to assist your service personnel. If additional assistance 
is required contact Kooltronic at (609) 466-3400
