Diverter installation is completed for testing,

1. Open the water inlet and return valves, the main water into the manifold, remove the flowmeter red sheath spin up the flow adjustment (collector spool open).
2. Automatic exhaust loose small cap, let the exhaust be in the automatic state, discharge the air inside the manifold.
3. Test the system in the fully open state to see if there are any safety leaks, and test the system for 24 hours (the pressure is stabilized at 1.0~1.2MPa),
4. pressure test 24 hours, check whether there is water seepage or dripping phenomenon in each component connection point. If an urgent shutdown is found into the return valve, repair the pipeline, and re-test.
5. System test indicators can fully meet the user’s requirements, and the pressure system pressure is back to normal use pressure, according to the user’s requirements for the use of fixed.
Note: The highest pressure value of the system can not exceed 1.2MPa.

Central PEX (cross-linked polyethylene) heating manifold is a plumbing system that distributes heated water or other fluids throughout a building. The manifold connects to a boiler or other heat source and distributes the heated fluid through a network of PEX pipes that run through walls, floors, and ceilings to provide heat to different rooms or zones. Here’s more information about central PEX heating manifold applications, raw materials, installation, sizes, and tips:

What is a Manifold

A manifold is a device or system that is designed to distribute, control, or regulate the flow of fluids, gases, or electrical signals to multiple outlets or components. It serves as a central hub or junction point where the flow is divided or combined, allowing for efficient and organized distribution.

The term "manifold" can refer to different types of devices or systems depending on the specific application. Here are a few common types:

Fluid Manifold: In fluid systems, a manifold is a structure that distributes fluid flow from a single source to multiple outlets or channels. It can be used in various industries, such as plumbing, hydraulic systems, fuel systems, and process control. Fluid manifolds can be made of materials like metal, plastic, or composite materials, and they often include valves, fittings, and connections for controlling and directing the flow.

HVAC Manifold: In heating, ventilation, and air conditioning (HVAC) systems, a manifold is used to distribute and balance the flow of air or refrigerant to different zones or components. It helps ensure proper airflow and temperature control throughout a building or system.

Electrical Manifold: In electrical systems, a manifold is a device that allows for the distribution and organization of electrical signals or power to multiple components or circuits. It can include connectors, terminals, or printed circuit boards (PCBs) to facilitate the flow of electrical currents.

Exhaust Manifold: In automotive engines, an exhaust manifold collects and directs the exhaust gases from each cylinder into a single exhaust pipe. It serves as a central junction point for the exhaust gases and helps optimize engine performance.

A heating manifold, also known as a heating distribution manifold or heating circuit manifold, is a device used in hydronic heating systems to control and distribute hot water or heat-carrying fluid to different zones or circuits within a building. It serves as a central hub for the supply and return lines of the heating system, allowing for individual control and regulation of temperature in each heating zone.

Applications of Minifold

• Residential and commercial heating systems
• Radiant floor heating systems
• Baseboard heating systems
• Hydronic heating systems

Raw materials:

• PEX pipes
• Brass or stainless steel manifold
• Pipe fittings and adapters
• Insulation
• Mounting brackets

How to install the minifold

1. Determine the number of heating zones or rooms and calculate the required length of PEX pipe for each zone.
2. Install the manifold in a central location, usually near the heat source, and connect it to the supply and return lines.
3. Install the PEX pipes in each zone and connect them to the manifold using fittings and adapters.
4. Insulate the PEX pipes to minimize heat loss and improve efficiency.
5. Mount the manifold to the wall or floor using brackets.
6. Fill the system with water and purge the air from the pipes.

Sizes: Central PEX heating manifold systems are available in various sizes, depending on the number of zones or rooms they are designed to heat. Manifolds can have as few as two ports and as many as 24 or more. The PEX pipes’ size will also depend on the heating load and the length of the pipes.

Tips:

• Make sure to properly size the manifold and PEX pipes for the heating load and the length of the pipes.
• Use high-quality PEX pipes and fittings to ensure a long-lasting and leak-free installation.
• Insulate the PEX pipes to minimize heat loss and improve energy efficiency.
• Purge the air from the pipes to prevent noisy operation and air pockets that can cause damage to the system.
• Consider installing a mixing valve to control the temperature of the heated fluid and improve comfort and efficiency.
