This operation is simple and involves the remo-
val of the three lower panels and disassem-
bly of the condensate tray for reassembly
on the opposite side of the heat exchanger,
turning it through 180°.
The central panel has a pre-punched hole
which is to be opened for the condensate
drain fitting.
When not in use, the hole must be carefully
sealed with closed-cell insulation.
