Installation Guide

Safety Information

Please read all instructions carefully before attempting to install or operate.

Do not remove the top or bottom covers of the unit.
Do not install the unit in a spot exposed to direct sunlight or excessive heat or the possibility of water splashing.
Do not subject the unit to excessive shock.
When replacing a fuse, only use a new one with the correct rating. Using a fuse with the wrong rating may cause the unit to malfunction.
