5. Installation of the valve

Requirements for the placement of valves in accordance with the Building Technology Regulations

In Norway, there have been requirements for the installation of automatic leak stoppers in new buildings and installations since TEK10 (Byggteknisk forskrift). Section 15-5, point (4) of the Regulations on Technical Requirements for Buildings (TEK17) under the Planning and Building Act (PBL) stipulates that leaks must be easily detected and not cause damage to water installations and building components.

The scope of coverage for automatic leak stoppers is described in the Building Code Regulations (TEK 17) with associated guidance, see Section 15-5, point (4), and is reproduced as an excerpt below:

Preconceived performances

1. Leaks from built-in cisterns or similar must be made visible. In rooms other than wet rooms, the
   In rooms other than wet rooms, the leak must also cause the water to be shut off automatically.
2. If the building's fixed water installation has an indoor tapping point where the leakage water will not
   flow to a drain or overflow, an automatic leak stopper must be installed. The same applies to
   applies to connection points for products and equipment that use water, such as washing machines and dishwashers. An automatic leak stopper is a moisture sensor that sends a signal to a valve that shuts off the water supply.

Waterguard+ is type-approved by Sintef (TG20834), which makes it possible to get the installation FG-approved. This may result in a discount on your insurance.

ATTENTION! In order to obtain FG approval for the installation of Waterguard+ automatic leak stoppers, an FG certificate must be completed.

The FG certificate template is available on Finance Norway's website under FG certificate leak stopper.

The FG certificate is the customer's proof that the installation, including the products, complies with the Norwegian requirements set out in the FG rules for automatic leak stoppers (FG-600:3).

The installation of Waterguard+ must be carried out by an authorized plumber with a valid professional certificate, central approval for liability law and mandatory liability insurance. Failure to do so will invalidate the warranty and FG approval, as well as make the installer liable for damages or faults.

Based on the description of the scope of coverage in TEK17 above, we recommend that Waterguard+ is installed so that the following areas are secured:

• Kitchen worktop with associated pipe connections
• Dishwasher with associated connections
• Washing machine with associated connections
• Water filters with associated connections
• Refrigerator with water connection and associated water pipes
• Drinks dispensers with associated connections
• Water heaters (boilers) with connection pipes
• Flueless rooms with sanitary equipment without overflow
• Rooms without a drain with a manifold cabinet for a pipe-in-pipe system with a drain into the room. Leakage from the pipe-in-pipe system is led to the distribution cabinet, where a detector or similar can be placed, which leads to
  shutting off the water. In distribution cabinets where the leakage water is led out of the wall and does not lead to a drain
  be equipped with a water sensor connected to an automatic leak stopper that shuts off the water.
• Concealed and open water pipes that are not secured with drained pipes or located in rooms with
  watertight floor and drain, must have an approved leak stop where sensors are installed that
  system detects, alerts and shuts off water leaks before damage occurs to the building.
  the building.
• Built-in cisterns, tap fittings or similar

If the dishwasher is installed in the kitchen worktop, leak stoppers are not required for both the
machine and worktop. Corresponding water installations that are not mentioned above must also be secured.

Important information regarding installation of valves

• The valves must be installed in a dry and frost-free environment and must be accessible for service/inspection at a later date.
• Filters must be installed before the valve if there is a possibility of larger particles in the water.
• Ensure that pipe sealing material does not end up in the valve during installation. This can prevent the valve from closing properly.
• The dimension of the valve must always be the same as or equivalent to the dimension of the pipe going in/out of the valve. Valves in size DN15 (1/2") are normally used for installation in kitchens, bathrooms and other wet rooms, while valves in size DN20 (3/4") are used for installation on main inlets to detached houses or larger residential units.

• Valves must be installed AFTER:

  • Manual stopcocks
  • Water meters
  • Pressure reducing valves
  • Outlet to sprinkler system
  • Fire hoses
  • Outlets for cooling of heating systems
  • Pressure tank or similar equipment
  • Water filtration systems

Room requirements for installation

Largest ball valve (3/4" - DN20) is 68 mm long and largest diameter is 38 mm. Valve actuator is 97 mm long and 57 mm wide, in addition there is a fixed cable of 100 mm with RJ45 connector at the end.

The total height of the valve and actuator is 92 mm from the bottom of the valve to the top of the actuator (77 mm from the center of the valve to the top of the actuator).

Linkbox+ covers an area of 119 mm x 119 mm and is approx. 30 mm thick (depending on the type of mounting bracket used).

Installation of ball valve (1/2" and 3/4" dimensions)

Ball valves with adapted dimensions are mounted on water pipes (brass, copper, stainless steel, galvanized or hard steel) with the appropriate connection method. The valves have G1/2 (DN15) or G3/4 (DN20) ISO-228 threads (HUN) at both ends.

The valves are classified as DN10 (max. working pressure 10 bar) and are tested according to EN13828 to 25 bar. EN13828 to 25 bar.

The valve can be installed horizontally or vertically and allows water flow in both directions (bidirectional).

Make sure that the closing pin of the valve points upwards (on or above the horizontal line of the water pipe). This ensures that the actuator is not positioned at the lowest point and that water does not collect in it.

Standard union with external threads (½" or ¾" depending on valve size) should be used for valve installation. Use a suitable thread sealant (e.g. thread tape, hemp + hemp paste or Loctite). Ensure that the selected thread seal is not inserted into the valve, as this may result in the valve not sealing completely when the water is shut off. Maximum torque when tightening must not exceed 75 Nm.

NB! Always perform a pressure test after installation to verify tight connections

Installation of actuator for ball valves

The actuator has a quick coupling and requires no tools for mounting on the valve.

1. Attach the valve actuator in the desired direction by placing it down on the closing pin of the valve.

If the position of the pin is not centered in the direction of the pipe, you can use the actuator to turn the pin in place (alternatively a wrench etc. and then the actuator for final fine adjustment). When the actuator is in the correct position, push it all the way down.

2. Insert the safety pin to lock the actuator to the valve. A noticeable click confirms that the pin is properly attached. Attempt to pull the actuator off to confirm that it is locked in place.

3. Insert the communication cable (Cat.6) between the actuator and Linkbox+. Make sure the cable clicks into place and locks into the connector.

Installation of cable splitter (for control of 2 ball valves)

The RJ45 cable splitter is an additional product that allows control of up to 2 ball valves from the same Linkbox+ (e.g. cold and hot water inlets in apartments).

1. Screw the splitter to the wall at a suitable location between the Linkbox+ and the valves using 2 screws (not included). Avoid overtightening the screws.
   
   NB! The contacts in the splitter must always point downwards to prevent water ingress.

2. Adjust the cables to the correct connector

3. Secure the cables with a noticeable/audible "CLICK"

Installation of 230V solenoid valves (1" to 2")

Danfoss solenoid valves (DN15-DN50) must be used for pipe dimensions over 3/4" or when three (3) valves need to be connected in series. Solenoid valves with adapted dimensions are mounted on water pipes (brass, copper, stainless steel, galvanized or hard steel) with suitable connection method. The valves have G1/2" (DN15) to G2 (DN50) ISO-228 threads (female) at both ends.

The valves can be mounted horizontally or vertically. The valves are unidirectional and the water must flow in the direction indicated by the arrow on the valve body.

Make sure that the valve's armature points upwards (on or above the horizontal line of the water pipe). This ensures that the solenoid housing is not placed at the lowest point and that water collects in it.

If the solenoid coil is not already attached to the valve's armature, press it down until you hear a noticeable "CLICK":

Installation of power adapter for solenoid valves

NOTE! Solenoid valves use 230V AC and not 24V DC like ball valves. As a result, the Power adapter for Linkbox+ and solenoid valves 24V DC / 230V AC must be used instead of the adapter supplied with Linkbox+.

The adapter can also be used to upgrade older Waterguard systems to Waterguard+ (from 1/2" to 2" 230V solenoid valves).

NB: When using the power adapter for solenoid valves, only Normally Open valves can be used.

1. Connect Cat.6 cable and 24V power cable to Linkbox+. NOTE! The port marked "Valve" must be used for the Cat.6 cable.

2. Connect the 230V power cable to the valve's magnetic housing and secure it with the supplied screws.

3. Plug the power adapter into a 230V AC socket

Installation of split and extension cable (for control of 2 or more solenoid valves)

Split cable for solenoid valves - 0.65 m allows series connection of up to three (3) solenoid valves from one (1) Linkbox+.

Connect the split and extension cable (0.65 m or 3 m) to both valves (further connected in series if 3 valves are to be controlled in parallel). Connect the 230V AC power cable (from the power adapter for the solenoid valve and Linkbox+) to the opposite end of the connector (connected to the left valve as shown in the illustration below).

Replace the standard 20 mm screw in the 230V AC power cable with the supplied screw which is 38 mm long. Then tighten the central screws to secure both power cables.
