In Windows 10, the F3 key is normally Find|Next. If you wish for the F3 key to delete lines, go to Options|Edit Options|Operations Options and turn on F3 Deletes instead of Find|Next (next to the red star).

The PRV calculations use the diameter of the downstream pipe to calculate the size of the angle or gate valve that is the friction loss of the PRV when the pressure in the pipe is already below the setting. The angle and gate valve equivalent fitting length is kept in the Options|Edit PRV Fitting Loss menu option. Sometimes the values in this table don’t get loaded correctly. To fix this, open the dialog using the menu option and push the reset button and click OK. This will load values into the table.

The error message for this is:

Unable to find the downstream pipe. The downstream pipe size at the PRV must be described in the data entry with a nominal diameter number.

HRS Systems is now using a licensing method that validates the license on each computer. This is checked during startup and at other times during program execution. To do this, the software needs to check the software and computer information against what is stored on the server. Your computer information is not directly stored on the internet. It is encoded so that your computer can be verified, but your computer information cannot be retrieved. This check must occur at least every two weeks. The software checks this every time you startup so that you have a full two weeks between connections.

Since each computer is licensed individually when you no longer need HASS on a specific computer, it should be deactivated and removed. To Deactivate a license from a computer, go to Help|Deactivate License.

When installing HASS, especially HASS2020, it is best to let HASS do all the work and change the values later unless you know exactly where all of your directories should go and have them set up.

This is the location of the HASS system files. At times HASS needs to access these files and needs to know where the latest ones are kept. The default location is

c:\program files (x86)\hrs systems\hass2020

or

c:\program files\hrs systems\hass88

The data directory stores files that need to be altered during program execution. Over the years, Windows has changed the security protocols so that most programs cannot modify files in the program directory without increased permissions. So, HASS stores the files in the data directory. It works best to place the data directory under the Documents directory. The data directories have three types – Data Directory, Pipe Table Directory, and Lock Box Directory.

The Data Directory holds most of the support files and is the first place to store the system definition files and others.

The Pipe Table Directory holds the pipe table files. This is separate so that a company can store their pipe table files on a server, and everyone can access them.

The Lock Box Directory contains backups of the system data files.

If you don’t have specific targets for these directories, let HASS suggest them.

In HASS2020, there are both English and Metric sets of data directories. These should be different directories. The most direct values are hassdata and hassdatm for these directories under the documents directory.

When a new version of HASS is installed, it tries to use the previous data directory. Sometimes this is not possible, or it is in a place that HASS can’t write to because of security protocols. To find your files go to File Explorer, which is the icon that looks like a manila folder in a metal stand at the bottom of the windows screen. Go to the c: drive and then search for the files that your software uses. For HASS, this is .sdf, and for HASSHouse, this is .rdf. For .sdf files put in *.sdf.

Sometimes the security software on a computer will quarantine HASS and put everything in a location under the AppData directory. The full path is usually c:\Users\(User Name)\AppData\Local\etc. Sometimes it is under AppData\Roaming, and even other times, it is under a temp directory. The search process will show the directory that has the files. The files can then be copied to the desired directory.

Pipe Tables are made to be modified. To avoid problems moving files from computer to computer, a standard pipe table is included when HASS is shipped, and it can’t be modified. But it is easy to make a copy and edit that. The steps are as follows:

1. Make sure that the pipe table directory is set to a directory that HASS can edit.
2. Go to Utilities|View Standard.pip
3. Go to File|Save as and save the pipe table with a new name. Be sure to keep the .pip extension. It is also best to keep the name relatively short – 8 or fewer characters is best, but it can be longer.
4. Make any changes you want to the pipe table.
5. Save your changes.
6. Go to File|Close to stop editing the pipe table.
7. When you have an open sdf use the Calc|Calc Information menu item to select your new pipe table and set the pipe table page.

You can set the initial pipe table and pipe table page when a new sdf is created. For HASS2020 this is set in Options|Edit Options|Initial Values Options. For HASS 8.8, this is set in Options|Edit System Parameters.

If the desired pipe table is not present, check your pipe table directory. Sometimes it helps to exit HASS and start it up again.

HASS 2020 gives the user some extra flexibility. If it doesn’t come up automatically, go to the Options|Edit Options|Display Options menu item and check “Display the Cover Sheet Dialog when opening an sdf”

This means that the master cover sheets are not in the data directories. In HASS2020, first, try Help|Extract Support Files. This will copy them if all is well. If that doesn’t work, copy the .mcs files from the HASS program directory to the HASS data directory, and that should resolve the problem.

HASS calculates the number of pages required to print your document and suggests all those pages. Sometimes the count is incorrect because the printer is changed after the calculation is made or there is a quirk from the font or paper size. Improving this is on our “To Do” list. Until it is fixed, there is an option to increase or decrease the number of pages required. In HASS2020, this in the Options|Edit Options|Print Options menu item. In HASS 8.8, this is the Options|System Parameters menu item. HASS will add the number of extra pages to the output that are entered.
