Indoor Unit Installation - Rinnai Pro Series Installation Manual

Indoor unit installation

Before installing the indoor unit, ensure the location is suitable:
• There needs to be enough room for installation, maintenance and service (refer diagram
below), and for connecting the pipe and drain pipe.
• The unit is installed level and the structure can support the weight of the indoor unit.
• The air inlet and outlet are unobstructed.
• The airflow rates and heating / cooling capacity are suitable.
• There is no direct radiation from a heat source.
DO NOT install in the following locations:
• Beneath a deck or other outdoor area
• In enclosed spaces such as cabinets
• Areas where power fluctuations are frequent
• Kitchens that use natural gas or LPG
• Areas with strong electromagnetic waves
• Areas that store flammable materials or gas
• Rooms with high humidity, such as bathrooms or laundry rooms
Where possible avoid installing the outdoor unit where it will be exposed to sea wind and salt
spray, this will significantly reduce the durability of the unit.
In severe environments (geothermal areas or areas with caustic gases) take precautions such as
applying additional corrosion protection to exposed components.
