6.11 Oil in evaporators - SWEP

The oil will thus flow out of the evaporator due to the force of gravity. It is then important to remeer that for dedied evaporator models the refrigerant must still enter through the F3 port because the distribution system is loed there. The force of gravity also increases the risk of liquid carry-over.
