Maintaining Your
Inverter
Your CPI 150 requires very little maintenance to keep it operating properly. The exterior of the unit should be cleaned periodically with a damp cloth to prevent accumulation of dust and dirt. At the same time, tighten the screws on the DC input terminals. Keep vents and fans free from dust or debris.
