Contractors are to adhere to the same guidelines as DNS.
Actually thats not necessarily true, each dns office had the authority to bend and or remove the rules for any of the subs that they farm out work to. For the better part of two years the DNS Wixom office cleared one of its subcontractors ( Don Lors ) to not ground apartment installs because there were so many of them coming through and the majority could not be grounded normaly.
Bottom line, nothing is set in stone with dish now or has it ever. Corporate has always had an issue with communicating with its own lower level employee's and all sales partner / subs. The pdf you listed is out of date wich is no surprise as many of dish's policies are vague and lacking in common sense points ( ask me about the MVR policy ). The management at the offices are given to much autonomy as well wich lends to the problem of chiefs and indians dilema and the result is further miscommunication and or a lack of.
