R407C must be charged as liquid. Usually R407C cylinder is equipped with a dip-pipe for liquid

withdrawal. If there is no dip-pipe, the cylinder should be inverted so as to withdraw liquid R407C

from the valve.

Do not top-up when servicing leak, as this will reduce the unit performance. Vacuum the unit

thoroughly and then charge the unit with fresh R407C according to the amount recommended in

the specification.

• The refrigerant gas has already been pre-charged into the outdoor unit. For the piping length of 5m and
