• Supply the electrical power to the system for approximately 12
hours before start-up after long shutdown. Do not start the system
immediately after the power supply, it may cause a compressor
failure, because the compressor is not heated well. Do NOT turn OFF
the power supply during the seasons. • Make sure that the outdoor unit is not covered with snow or ice. If
covered, remove it by using hot water (less than 50ºC).
• If the water temperature is higher than 50ºC, it will cause damage to
plastic parts.
