Hmmmm. Now how do we figure out if we have one of those? When I deflate, it seems like it is a two step process. First, for several seconds, the air is expelled from the bladder...then something happens and the bladder really flattens out.....then the slide comes in. It acts like it has a vacuum pump, but I don't know. Any idea on when they started putting them in? My coach was one of the first ones with the Valid electric slides.

Bill,

It sounds like you already have the vacuum pumps installed. You can check with Newell and I'm sure they can verify it.

tuga, do you have a regular part number for the vacuum pump? i know they use a regular f350 vacuum pump on the dash up front for the louvers because i put one in my 90 to replace the air powered one that leaked.

i am also curious as to how that is plumbed in. i assume right where the regulator is for the slide seal.

tom,

i am out of town now, so i don't have access to my maintenance records. it is plumbed (i think) after the solenoid under the bed. it works great

the operator has to be careful to wait until the vacuum pump stops pumping before they extend/retract the slideroom. you can't go by the yellow light anymore. it takes an additional 45 seconds for the vacuum pump to completely deflate the bladder.

when i return home i will post the vacuum pump number. for $100 it is a bargin.
