When Using and Installing In Cold Areas
When the air conditioner is used in low temperature and in snowy conditions,
water from the heat ex changer may freeze on the base surface to cause
poor drainage. When using the air conditioner in such areas, do not install
the bushings. Keep a minimum of 250mm between the drain hole and the
ground. When using the drain pipe, consult your sales agent.
