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 piping and temperature sensor wiring length come within the allowable ranges.
Outdoor units should be installed in locations where the noise from the unit will not disturb neighbors.
Outdoor units should be installed in safe places which can bear the unit's weight and vibration and where the unit
can be installed at an even level.
Outdoor units should be installed in positions that there is no possibility of flammable gas or product leak.
Outdoor units should be installed in positions where servicing space can be well ensured.
Outdoor units should be installed in positions where rain can be avoided as much as possible.
Outdoor units should be installed in clean area in case of small animals making contact with electrical parts, which can
cause malfunction, smoke or fire.
There is flammable refrigerant in the unit and it should be installed in a well-ventilated site. If the unit is installed inside,
an additional refrigerant detection device and ventilation equipment must be added in accordance with the standard
EN378.
Adequate measures should be adopted to prevent the unit from being used as a shelter by small animals.
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:
Set the outlet side at a right angle to the direction of the wind, refer to Figure 3-2.2. For installation of the outdoor
unit in a place where the wind direction can be foreseen, refer to Figure 3-2.3 for installation of the unit.
If turn the air outlet side toward the building's wall, fence or screen. Make sure there is enough room to do the
installation
