New Preventative Maintenance Program

APLI is pleased to announce our new preventative maintenance program. Under this program, APLI will send a technician to your site to service your equipment on a semiannual, annual, or combination program. The semiannual procedure is basic preventative maintenance, the annual maintenance procedure is a complete inspection, cleaning and thorough check-out of your equipment and the combination agreement combines both the semiannual and annual trips and comes with a limited warranty.

This program includes the following procedures.
