Installation
Pre-Installation
Please be aware of the following before mounting and installing
the remote user interface.
Location Considerations
Placement of the remote user interface is necessary to
ensure proper operation. When selecting a location, avoid the
following:
• Locations that are outside the operating temperature and
humidity range (see
Environmental Conditions.
)
• Mounting on rooftop without a careful site evaluation and
confirmation
• Walls that are subject to high vibration
• Areas with high humidity exterior walls and other walls
that have a temperature differential between the two
sides
• Areas that are close to heat sources such as sunlight,
appliances, concealed pipes, chimneys, or other heat-
generating equipment
Mounting Surfaces
For surface installation, mount the remote user interface to a
flat surface such as sheet rock or plaster, control panel, or an
electrical junction box.
• If mounting onto sheet rock or plaster, use anchors, if
necessary
• For mounting in the unit controller panel, electrical
junction box, or other metal enclosure, use the supplied
magnets.
