16 MTU Installation Guidelines
Interior
Moving the MTU several feet away from the duct and the refrigerator will
eliminate the interference and increase system performance considerably.
Summary
• Mount the MTU as high as possible near an exterior wall. The MTU must be
mounted at or above grade (ground level).
• Mount the MTU perpendicular to the ground with the Aclara logo facing the
installer.
• Mount the MTU at least six inches away from pipes and conduit.
• Mount the MTU so that the top is several inches below the ceiling.
• Mount the MTU at least five feet away from any large metal objects. (e.g.
refrigerators, HVAC ducts, furnaces, and hot water heaters)
• Do not mount the MTU in a basement with a metal ceiling.
• Do not
mount the MTU directly under AC power wires, circuit breaker
panels, or telecommunications wires.
