1. Selecting the installation location and restrictions on
installation
1-1 Selecting the installation location
Select a location which will ensure that the restrictions on installation described in 1-2 will be complied with.
Also, make the selection while giving due consideration to providing enough space (for removing the front
panel, etc.) for subsequent servicing and repairs.
• Install the unit on a flat, level surface.
• Provide the openings required for replacing parts (and even the unit) and the space required for the
inspections.
• Do not install the unit in an area where the minimum temperature may drop to –25°C or below since the
unit may not run properly under these conditions.
• Do not install the heat pump unit indoors.
• Do not install the unit in a very humid or damp place such as a bathroom.
• Do not install the unit where water will pool and flood the unit when rain or snow has fallen.
• Do not install the unit onboard a ship or in a vehicle since the shaking and vibration may cause the unit to
fail.
• Take steps to prevent snow from entering the air intake and outlet by, for example, installing the heat
pump unit on a stand. Also, put a roof over the unit to keep the snow off.
• Do not install the unit near sources of inflammable gases or objects which may ignite or catch fire.
• Install the heat pump unit in a location where the air blown out and operating noise will not inconvenience
the neighboring homes, where there are adequate clearances from the walls, where servicing can be
performed, etc.
• Install the area with the thermistor at the back of the outdoor unit in a location where it will not be
exposed to direct sunlight, reflected light, etc.
the unit may be relocated (or dismantled and discarded) at a future point in time, ensure that the
• Ifsurrounding
environment (buildings, water drainage ditches and gutters, etc.) will not be adversely
affected.
