5.1.2. Outdoor unit
J6: facility setting jumper and switch (cooling at low outdoor temperature)
Outline: this function is limited only for facilities (the target of air conditioning is equipment such as computer). Never use it in spaces occupied by humans such as a residence or office.
Detail you can expand the operation range to -10°C by cutting the jumper or turning on switch on the outdoor unit PCB. If the outdoor temperature falls to -15°C or lower, the operation
stops. If the outdoor temperature rises, the operation starts again.
J8: facility setting jumper for improving defrost performance
Improves defrosting performance by enabling the onsite setting of this function in the event frost remains when the equipment is used for heating operation under extremely low temperatures
and severe environmental conditions, such as in Europe.
J12: snow accumulation prevention fan for cold areas
In heavy snow areas, snow may cover the outdoor unit, a snowdrift pile may be formed near the outdoor unit, or icicles may reach the outdoor unit during the night. If such conditions are
left uncorrected, operating the air conditioner in the next morning can cause damage to the outdoor unit fan or result in a fan lock error, disallowing proper heating operation in some cases.
If cut jumper, outdoor unit fan operates intermittently at low ambient.
