ColorTech fixtures are furnished with standard size inlet shanks which penetrate the deck or wall surface. Minimum acceptable hole sizes for these shanks are listed below. We recommend using the minimum acceptable hole size to accommodate the mounting shank. This will minimize the possibility of lateral movement of the fixture and provide as large a surface as possible for the locknut and lockwasher to secure against.

Requirements for the size and material of supply piping are generally covered by local plumbing codes. Reference should be made to such codes when laying out piping for service fixtures and safety equipment. Pipe sizing is also affected by the number of fixtures or outlets installed on a run. However, typical piping standards for single fixtures and outlets are as follows:

Installing WaterSaver laboratory faucets, valves and safety equipment requires the use of common plumbing installation techniques. Observing the following guidelines will help to assure trouble-free installation:

1. Thoroughly clean and flush supply lines prior to installing faucets and valves. Pipe shavings, scale, tape and other debris can be carried through a pipe and into a faucet or valve when the system is activated. This debris can damage valve components and interfere with the proper operation of the faucet or valve.
2. When placing a faucet or valve on a laboratory countertop or wall, secure the fixture using the lockwasher and locknut. Tighten the locknut sufficiently to secure the fixture to the counter or wall. Do not overtighten.
3. In order to function properly, vacuum breakers must be installed in a vertical position, perpendicular to the finished floor. When installing a remote vacuum breaker (such as the L102 or L112), we recommend using a level to make sure that the vacuum breaker is installed in a plumb and level position.
4. Generally, WaterSaver fixtures have American National standard taper pipe threads (NPT) on the inlet. Use Teflon tape or other pipe sealant to seal these threads. Do not apply the sealant in a way that will permit it to enter into the faucet or valve.
5. Observe the maximum test and working pressures for faucets and valves. Testing or using a valve at pressures for which it is not designed can result in leakage or failure. Refer to the Valve Selection Guide for information on maximum test and working pressures.
6. Do not use valves for services and applications for which they are not intended. In particular:
   • Valves for oxygen service and high purity gases must be specially cleaned, lubricated and packed. Ball valves and needle valves which have not been specially cleaned are not acceptable.
   • Needle valves should be used for gas services only. They are generally not suitable for use with water or steam.
7. To prevent surface damage, use caution when applying a wrench or other tool to the exter­ior of a faucet or valve.
8. Every WaterSaver faucet is fully assembled at the factory. This includes installing the gooseneck into the faucet body and the outlet fitting into the gooseneck. Mounting shanks are furnished either loose (designated by the suffix “WS”) or assembled (designated by the suffix “WSA”), as ordered.
9. WaterSaver valve assemblies (such as needle valve or ball valve assemblies) are factory assembled, inspected and tested. Mounting shanks are furnished either loose (designated by the suffix “WS”) or assembled (designated by the suffix “WSA”), as ordered. Factory assembly permits us to test the connections between the valve, the mounting fitting (turret or flange) and the mounting shank. Factory assembly also minimizes the field labor required to install the fixture and minimizes the possibility of damaging the fixture’s finish during installation.
10. Clean faucets and valves using a soft cloth and soapy water. Do not use abrasives, detergents or other cleaners which can damage the finish on the fixture. In particular, do not use any solvent in or near a faucet or valve. Solvents can dissolve the lubricants used in the valve mechanism.
