2.3
Placement Considerations
Placement of the outdoor unit should take account of the following considerations:
Outdoor units should not be exposed to direct radiation from a high-temperature heat source.
Outdoor units should not be installed in positions where dust or dirt may affect heat exchangers.
Outdoor units should not be installed in locations where exposure to oil or to corrosive or harmful gases, such as
acidic or alkaline gases, may occur.
Outdoor units should not be installed in locations where exposure to salinity may occur.
Outdoor units should be installed in well-drained, well-ventilated positions.
Outdoor units should be installed in positions that are as close as possible to the heat emitters.
Outdoor units should be installed in positions that are sufficiently close to the desired position of the wired controller
that the controller’s wiring length limitation will not be exceeded.
In systems that are configured to heat domestic hot water and/or include an external backup electric heater, outdoor
units should be installed in positions that are sufficiently close to the domestic hot water tank and/or backup electric
heater that the temperature sensor wiring length limitations will not be exceeded.
Outdoor units should be installed in locations where the noise from the unit will not disturb neighbors.
2.4
Strong Wind Installation
Wind of 5m/s or more blowing against an outdoor unit’s air outlet blocks the flow of air through the unit, leading to
deterioration in unit capacity, accelerated frost accumulation
when in heating mode or domestic hot water mode, and potential
disruption to operation due to increased pressure in the
refrigerant circuit. Exposure to very strong wind can also cause the
fan to rotate excessively fast, potentially leading to damage to the
fan. In locations where exposure to high winds may occur should
take account of the following considerations:
For installation of the outdoor unit in a place where the wind
direction can be foreseen. Set the outlet side at a right angle
to the direction of the wind, refer to Figure 3-2.2.
If turn the air outlet side toward the building's wall, fence or screen. Make sure there is enough room to do the
installation
