Rail Mounting
Split Rooftop Units can be installed on rails provided and installed by others. Ensure that rails are designed to handle the weight of the unit
and provide proper load distribution on building supports.
• Make sure that rail positioning does not interfere with the openings on the unit.
• Rails should run the width of the unit and extend beyond the unit a minimum of 12 inches on each side.
• Set unit on rails.
See Figure below for example of a typical RTU installed on rails supplied by others.
Figure 13: RTU - Installed on Rails.
• Ensure that the rails are designed to handle the weight of the unit. If the rails don't have sufficient strength, the unit will fall and cause
physical injury or death.
• Ensure that the chosen location has enough strength to support the weight of the unit(s). If it does not have sufficient strength, the unit(s)
will fall and cause physical injury or death.
• Install the Split Rooftop Unit to protect against extremely high winds and earthquakes. Any deficiency in installation will cause unit to fall,
resulting in physical injury or death.
