Maintenance

Very little maintenance is required to keep the invert-
er 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. Be sure
vents and fans are free of dust or debris.
