Cautions in winter especially for seasonal wind
• Sufficient measures are required at a snow area or severe cold area in winter so that product can be operated
well.
• Get ready for seasonal wind or snow in winter even in other area.
• Install a suction and discharge duct not to let in snow or rain.
• Install the outdoor unit not to come in contact with snow directly. If snow piles up and freezes on the air suction
hole, the system may malfunction. If it is installed at snowy area, attach the hood to the system.
• Install the outdoor unit at the higher installation console by 50cm than the average snowfall (annual average
snowfall) if it is installed at the area with much snowfall.
• Where snow accumulated on the upper part of the outdoor unit by more than 10cm, always remove snow for
operation.
1. The height of H frame must be more than 2 times the snowfall and its width shall not exceed the width of the
product. (If width of the frame is wider than that of the product, snow may accumulate)
2. Don't install the suction hole and discharge hole of the outdoor unit facing to the seasonal wind.
CAUTION
• Always apply main power of the outdoor unit during use of product
(cooling season/heating season).
• Always apply power before 6 hours to heat the crank case heater where performing test run after instal-
lation of product or where operating the product after cutting the main power of the outdoor unit (for
example, power failure). It may result in burning out of the compressor if not preheating the crank case
with the electrical heater for more than 6 hours.(In case of the outdoor temperature below 10°C)
