Maintenance
The Spectra IV dome systems do not require any special maintenance.
Occasionally, dust may build up on the inside or the outside of the dome. If this occurs, turn power off to the unit and remove the lower dome
from the back box. Remove the dust from the lower dome using compressed air from a spray can. Replace the lower dome following the
installation instructions that were shipped with it.
Warning: Proper eye protection should be worn when using compressed air cans.
