Connecting your Heatpump UFH kit to your underfloor heating manifolds involves a few key steps. Before you begin, gather the necessary tools and ensure you have all the components of the kit. Here's a step-by-step guide:
-
Secure the Manifolds: Begin by securely mounting the distribution manifolds to the wall. Ensure you have adequate space around the manifold to accommodate the Heatpump UFH kit. Check the kit's manual for specific dimension requirements.
-
Inventory Check: Confirm that you have all the components listed in the Heatpump UFH kit's pack contents. This usually includes the Heatpump UFH Connection Block, a Grundfos UPM3 Pump, various connectors, washers, and any required tools.
-
Determine Orientation: The Heatpump UFH kit is designed with flexibility. It has two return ports, so decide on the orientation that best suits your existing setup and the location of your heating system's return pipes.
-
Connect Straight Connector: Screw the straight connector, which is provided with the kit, into the return port. Use the appropriate tool to tighten the connector firmly.
-
Connect Angled Connector: Depending on the layout of your supply pipework, connect the angled connector to either the flow or the return port on the Heatpump UFH kit.
-
Attach the Pump: Attach the body of the Heatpump UFH kit to the pump, using the pre-assembled pump nut. Make sure the pump washer is correctly inserted. Also, pay close attention to the directional arrow that is marked on the pump body.
-
Fit Pump Nut: Ensure the 1 ½” pump nut is placed on the flow connection elbow. If it isn't, slide it over the flanged connection face.
-
Connect Elbow to Pump: Use the 1 ½” pump nut to connect the nickel-plated elbow to the pump. Tighten the pump union connections to secure it.
-
Connect Elbow to Manifold: Connect the elbow to the flow manifold. Use the 1” MBSP connection onto the flat-faced union connection. Remember to use the 1” fibre washer.
-
Complete the Connection: Connect the Heatpump UFH kit body to the return manifold. Use the 1” MBSP connection onto the flat-faced union connection, and verify that the 1” fibre washer is in place.
-
Wiring: Provide a fused spur close to the manifold to power the pump and any zone valves. The pump usually comes with a plug-in cable for simplified installation. Always have all wiring performed by a qualified installer in compliance with the latest IEE regulations. Always refer to the installation guide that came with your specific Heatpump UFH kit for any specific details or variations based on your model. If you run into any difficulties, don't hesitate to seek professional assistance to guarantee a secure and correct installation.
