Please tell me where do I put the water in this unit. I would have thought underneath the mattress tray, however there is a hole which goes directly to the fan & electricals and if water is put underneath the mattress tray, this fan & electricals will get wet as you can shine a torch through from 1 side to other.
Could you please help me and tell me where to put the water in this unit.
Thanking you
Lyn
