Smart Connect Technology – Security Under Pressure
Locating unpressed connections is an important step in the pressure-testing process. Viega MegaPress CuNi includes Smart Connect technology, providing quick and easy identification of unpressed connections during a pressure test.
Smart Connect technology is a design of the fitting, providing a path for liquids and/ or gases from inside the system past the sealing element of an unpressed connection. When pressed according to our Product Instructions, the fluid path is altered, creating a reliable, leakproof connection.
Unpressed connections are located by pressurizing the system with air or water.
When testing with water, the proper pressure range is 15 to 85 psi. Pressure testing with air can be dangerous at high pressures. When testing with compressed air, the proper pressure range is ½ to 45 psi. Following a successful Smart Connect test, the system may be pressure tested up to 600 psi maximum for water and 200 psi maximum for air if required by local code requirements.

2½ to 4| 64 to 102| 12| 305| 1¼| 32

No-Stop Couplings
No-stop couplings are often used to conduct repairs. Without a stop, these couplings can slide completely onto a pipe and allow a connection to be made in tighter spaces. Unlike fittings with an integrated stop that have a minimum insertion depth, no-stop  couplings have minimum and maximum allowable insertion depths. The minimum and the maximum insertion depths should be marked and a line should connect the two marks.

Welding
The following requirements must be considered when welding in the same vicinity as Viega MegaPress CuNi fittings.

Welding Requirements
The installer should take precautions to keep the MegaPress CuNi connection cool:
■ Wrap the connection with a cold, wet rag.
■ Protect the connection with a weld blanket.
■ Prefabricate solder connections/welded fittings prior to installing the press fitting. (Ensure pipe has cooled before installing the press fitting.)
■ Apply heat sink gel or spray or spot freezing.

Welding Adjacent to a Press Fitting
To prevent damage to the sealing element, maintain proper welding distances from the fitting. If welding adjacent to the connection, weld a minimum of four inches away.

Welding in Line With a Press Fitting
To prevent damage to the sealing element, maintain proper welding distances from the fitting. If welding in line with the connection, weld a minimum of three feet away from the connection to protect the sealing element.

General Installation Notes
Expansion
Thermal expansion in installed systems generates stress on pipes and appliance connectors. Compensation must be allowed for expansion and contraction that may occur within the piping system. Expansion joints or mechanical expansion compensators may be used to alleviate these stresses.
Electrical Bonding
When properly installed, MegaPress CuNi fittings comply with Section 1211.15
Electrical Bonding and Grounding of the Uniform Plumbing Code.
The mechanical press provides continuous metal-to-metal contact between fitting and pipe. The press ensures the continuity of the bonding through this contact.

DANGER!
Electric Shock
An electric shock can cause burns, serious injury, and even death.
■ Because all metallic piping can conduct electricity, unintentional contact with a live wire can lead to the entire system and components connected to it to become energized. Metal piping is not meant to conduct electricity.
■ A properly bonded system creates a safe path for electricity to travel so that the system can’t be energized.
■ An unbonded or improperly bonded system can be a shock hazard.
■ Always ensure bonding is in accordance with local codes.

Exposure to Freezing Temperatures
In the Viega MegaPress CuNi system, the FKM sealing element can be installed in ambient temperatures down to 23°F (-5°C). Piping systems exposed to freezing temperatures must be protected per acceptable engineering practices, rules, and as required by the governing authority.

Underground Installations
Viega MegaPress CuNi fitting systems with copper pipe are approved for underground installations. However, installations must meet all state and local codes, including those for underground.
Proper authorization must be obtained from the Authority Having Jurisdiction prior to installation.
Concealed Spaces
The Viega MegaPress CuNi fitting system has been approved for use in concealed spaces. Specific performance tests were conducted to evaluate the fittings for use in concealed spaces. Concealed pipe and fittings shall be protected from puncture threats.

Corrosion Protection
Viega MegaPress CuNi fittings exposed to corrosive conditions must be protected in an approved manner in accordance with NACE Standard RP0169-2002 Section 5, and in a manner satisfactory to the governing official.
Transition Fittings – Threaded
Viega MegaPress CuNi systems can be joined with off-the-shelf threaded fittings made of non-ferrous metals. In this regard:
■ The threaded connection is made first.
■ The press connection is made second.
This process avoids unnecessary torsion on the press fitting.
Transition Fittings – Flange
When using Viega flanges, bolt the flange end in place prior to pressing the fitting to the pipe.

Deflection
The pressing process can cause deflection (angular misalignment) to occur. When pressing Viega MegaPress CuNi fittings in a system, the deformation of the fitting is constant. This allows for a consistent leak-free joint every time and is a result of the pressing technique.
Deflection occurs in the same way for every fitting. The fitting being pressed will move in the direction of the jaw or ring opening.

■ Since the fitting will deflect toward the opening of the jaw or ring, the pipe end will deflect in the opposite direction.
■ By counteracting the fitting movement, one can minimize the deflection of the fitting and ultimately the pipe.
■ When using strut and clamps, deflection is minimized and nearly eliminated, depending on clamp spacing.

Controlling Deflection
Deflection while pressing can be minimized by utilizing the following installation practices.

Alternate Press Directions
■ Press one end of fitting.
■ Make second press on other end of fitting from the opposite side.

Push-Pull Method
■ Rings = Push on press tool.
■ Jaws = Pull on press tool.
The press tool can be feathered using the trigger as needed to apply pulling or pushing force to control deflection.

Re-Press
■ Press the fitting, once on each side (that is, re-press the fitting a second time on the opposite side).
■ Pressing the same connection from the opposite side will usually straighten misalignment between the pipe and fitting.

■ When pressing overhead piping, it may be inconvenient to alternate sides for each press.
■ The natural weight of the piping plus pressing on opposite sides at a 45-degree angle should adequately eliminate deflection.
■ This technique can also be used for any horizontal piping and when working above the piping.

Tool Clearances
Minimum distances should be taken into consideration during planning in order to avoid space constraints during installation.
Ensure that the space required for pressing tools is available if Viega MegaPress CuNi fittings will be installed immediately upstream or downstream from wall or floor penetrations.

Frequently Asked Questions

Q What is Smart Connect technology?

A Smart Connect technology provides a quick and easy way to identify unpressed connections during the pressure-testing process. Unpressed connections are located by pressurizing the system with air or water. When testing with water, the pressure range is 15 psi to 85 psi maximum. When testing with air, the pressure range is ½ psi to 45 psi maximum. The flow path is removed during the pressing process, creating a leakproof, reliable connection. Guaranteed.

Q Why is Smart Connect technology so valuable?

A Smart Connect technology gives the user strong peace of mind. It allows for faster testing procedures since you do not have to shut down and drain the system. Costly damages and possible insurance claims and premiums can be avoided because it identifies unpressed connections before they can become a problem. Because of the time savings, projects stay on track.

Q Do I need additional equipment to install Viega MegaPress CuNi Systems?

A No. Viega designed Viega MegaPress CuNi fittings to be compatible with the same jaws, rings, and press tools that are used for the Viega MegaPress Carbon Steel and Viega MegaPress Stainless systems.

Q If a leak is discovered, is it necessary to drain the system prior to pressing the connection?

A No. It is not necessary to drain the system when making a repair.

Q How would an inspector know they are looking at a good connection?

A Good connections can be proven by performing a pressure test, using the same procedure for a fitting system.

Q What is the lubrication used on the sealing elements?

A The sealing elements are lubricated with a USDA approved H1 lubricant, meeting the requirement of FDA 21CFR. If it is necessary to lubricate the seals in the field, use water only. Do not use petroleum-based lubricants.

Q How long will the FKM seal last?

A When properly installed, the FKM seal and connection will last as long as the piping system.

Q How do I fabricate a system in tight places when using Viega MegaPress?

A If necessary, prefabricate connections that are in tight places and then install.

Q What is the warranty for Viega MegaPress CuNi fittings?

A Viega MegaPress CuNi fittings carry a two-year warranty against defects in material and workmanship from Viega.

Q How do Viega MegaPress connections hold up to freezing temperatures?

A Precautions should be taken for any piping system to protect the system from below-freezing temperatures.

Q What level of turbulence occurs in Viega MegaPress CuNi fittings and will it cause premature wear in the piping?

A The long radius of Viega MegaPress CuNi elbows reduces turbulence typically experienced with traditional short-radius fittings. Not reaming the ID of the pipe is the largest contributing factor to turbulence and premature wear of any piping system.
