Thanks for the basics. That's already taken care of. I work at an Embassy in the middle east which doesn't have any factory assistance or tech support. Our units were installed by some Turkish contractors and then removed from the job when it was discovered these" mechanics' were not licensed nor certified for the install. Needless to say I've inherited quite the mess and with a staff of just two. the Units are also under EN-81 European code and holy hell.

Thanks.
