How do I know the Perma needs to be changed out?
Answer
You will be able to see the red nylon piston through the unit's clear nylon cap in the Perma Classic & Frost units. The Futura and Star have plastic housings so the status of the lubricant is always apparent. Also, adding the Perma's installation and changeout dates to your customer’s preventative maintenance program will take the guesswork out of the changeouts. And, we offer a Windows-based Tracking Program.
