Additional refrigerant charging = 250g + 450g = 700g
3) The total amount of additional refrigerant charging = the amount of refrigerant charging for pipe + the amount of
refrigerant for each indoor unit.

Connecting the drain hose to the outdoor unit
When using the air conditioner in the heating mode, ice may accumulate . During de-icing (defrost operation), the
condensed water must be drained off safely. Consequently, you must install a drain hose on the outdoor unit,
following the instructions below.
Leave space of more than 50mm (1.97 inch) between the bottom of the outdoor unit and the ground for installation of
the drain hose, as shown in figure.
Insert the drain plug into the hole on the underside of the outdoor unit.
Connect the drain hose to the drain plug.
Ensure that the drained water runs off correctly and safely.
50mm (1.97 inch)
Be sure to plug the rest of drain holes not connected with drain plugs using drain caps.
