The evaporator on R-600a models is of the Fin and Tube type with the expansion and suction inlet/outlet on
the left hand side. The defrost element is fitted to the right hand end plate of the evaporator and clamped
into position. The R-600a evaporator does not have an accumulator fitted. This is to reduce the risk of oil
slugging with the type of refrigerant used.

Condensate Disposal
During the defrost cycle, which is electronically timed and controlled, live frost is melted off the evaporator by
means of heat from the defrost element. Condensate from the evaporator defrosting drops into a collection
trough, which has an outlet hole in the centre of the liner. A tube then allows the condensate to flow into a
water evaporation tray above the compressor.

Filter Drier
Diagram 4.7
The filter drier or molecular sieve, as the name suggests, is both a filter and a drier. Whenever a system is
opened it is essential that the filter drier is replaced. ALWAYS ensure that replacement filter driers are kept
well sealed and airtight prior to being fitted to a system.
NOTE:
When filter driers are replaced on systems being serviced,
it is important that the filter drier is
either cut from the system or the desiccant is removed before heat is applied to the old filter drier.
Failure to do so will drive any moisture held in the desiccant back into the system.
ALWAYS
mount vertically or as near to vertical as possible and use the correct desiccant to suit the
refrigerant being used.
XH7 or XH9 suits R-600a.
