Evaporator Water Drain Valve, Checking

Fig. 1:

- Fold cover -1- in bulkhead insulation mat -3- upwards.
- Remove drain valve -2- from opening in bulkhead -4-.

Check water drain valve as follows to ensure correct function:

- The water drain valve must not be stuck together.
- Insulation mat must not be deformed or damaged in the area of water drain valve.
- The opening in the sealing cap of the water drain valve must point downwards.

NOTE: When the cover cap -1- is closed it must be flush with the insulation matting. If the cover cap -1- is pushed in too far the water drain valve sealing cap -2- can become jammed.
