- Before inserting evaporator, clean evaporator housing and evaporator if necessary.

- When inserting evaporator - A - into lower section of evaporator housing and when assembling both housing halves, ensure foam seal - F - is not damaged.
- Check seal - F - (it must be glued all around) before inserting evaporator.
- Place bracket - C - and seal / insulation - B - onto connecting pipes of evaporator - D - and - E -.
