Hi Guys,

I recieved a couple of weeks ago a service bulletin which no doubt some of you will have seen. It relates to the positioning of a TEV and say's that they can maulfunction if not vertical. Now as far as i am aware TEV's are operated using pressure against an internal spring so what difference does it's location make. Here is the Bullentin apart from the manufacturer blanked out.

Problem:-
######## is now aware that a small number of these units were manufactured with the TEV Valve in a horizontal attitude. This may result in the vale operating in a partially closed manner. This will cause the evap and the TEV to become iced up.

Solution:-
The TEV needs to be orientated so the head is above the body, and the valve should be made as vertical as possible.

Any Comments

Regards

Hi Raymond,

I have raised the subject a while ago and with the help of Prof. Sporlan , the conclusions was the same.

But..... other opinions and experience will be most welcome.

My first thought would be with oil/liquid accumulating around one (lower) of the guide pins and slowing/blocking the valve action; but what do I know ;)
