step by step guide
7 Record and reportAmbiLowboard (SRB) is a high density, flexible cement based board solution for laying over a flat subfloor. It is particularly recommended for tiled floor areas because the high compression rating of the board and lap joint detail permits tiles to be laid directly over the top when using a decoupling matting. We recommend priming the boards before laying floor coverings in all cases.
The system uses an Ambiente five layer, 12mm PE-RT with EVOH oxygen barrier pipe. The pre-grooved channels provide installation flexibility as just two board designs can be used for all pipe run combinations. The panels can also be easily routered where required for added flexibility.

INSTALLATION METHOD
1 Refer to the design plan drawings and
prepare to lay the floor in accordance with the layout described.
2 Surface must be flat and clean before
laying AmbiLowboard (SRB) Start in the furthest corner of the room that is furthest from where the pipes enter the room.
3 Use one RX board cut in half for areas
where only one return loop is required.
4 Use full width RX boards in areas where
two return loops are required to accommodate both transit pipe for loop 1 and flow and return for loop 2. RX boards are also required in doorways where pipes enter and leave the room.
5 Spread AmbiLowboard (SRB) joint glue
along the bottom lap and lay the lap of adjacent board on top and secure with 16mm lap screws.
6 Starting at the manifold, lay the pipe
according to your design drawing, navigating the most efficient route between the manifold and the zone. Lay the pipe into the pre-grooved boards, as per your system design drawings.
7 On completion of the loop, connect
to the return bar (bottom bar with blue caps). Mark up the manifold tag with the loop length and the room name.
8 Once all loops are installed and
connected to the manifold, pressure test the system.
9 Lay final floor finish after the system
has been successfully pressure tested. We recommend priming the boards before laying floor covering in all cases.

Ambiente manifolds are supplied ready assembled and simply need mounting on brackets prior to installation.
Note that the two manifold bars are offset so that the pipes can pass behind the lower bar for connection to the top bar – we recommend using the top bar as the flow and the bottom bar as the return. The manifold comes left-handed as standard, but can be changed, see opposite for ‘how to change the handing of Ambiente manifolds’.
Manifolds should be positioned where they are easily accessible to allow for future servicing and commissioning. We recommend allowing at least 200mm between the finished floor level and the bottom of the manifold, with 75mm clearance above and at least 50mm at either side.

COMMISSIONING THE SYSTEM STEP BY STEP CHECKLIST
Filling and flushing the system
Sequence Checklist Completed
1 Close the isolating ball valves that are connected to the manifold on both bars.
2Isolate all zones by screwing down the blue caps on the bottom (return) bar and the flow meters on the top (flow) bar.
3Open the first flow meter (start furthest away from the filling valve) on the top (flow) bar (use the red collar to turn the black section fully anti-clockwise, do not use grips – hand tight only). Ensure that all other flow meters are closed, except the loop that you are flushing.
4Remove the black plastic blanking cap from the filling valve on the top (flow) bar and fit the hose connection/hose which should be connected to the mains water supply. Open the filling valve using the key on the reverse of the drain valve cap.
5 Fix a suitable hose to the drain valve on the bottom bar.
6 Fully loosen the blue protection cap on the bottom bar on the first zone to be filled.
7Open the tap on the mains water supply and open the drain valve on the bottom bar using the key on the reverse of the blanking cap.
8Run water through the loop until air is removed from the system, closing down the blue caps on each loop as it is purged.
9This can now be repeated for each zone by opening the next zone, closing the flushed zone and repeating steps 3-8.
10At this point the system can be pressure tested if required by closing the drain valve and unscrewing all the blue protection caps – the pressure should rise slowly – allow it to rise to 4 bar and then close the filling valve and close off the mains water. This should be left for 24 hours to check for any significant drops in pressure.
Pressure testing using an air compressor
Sequence Checklist Completed
1 Close the isolating ball valves that are connected to the manifold on both bars.
2 Open all zones by unscrewing the blue caps on the bottom (return) bar.
3 Open all flow meters on the top (flow) bar – use the red collar to turn the black section fully anti-clockwise.
4Open the filling valve using the key on the front of the blanking cap and connect the compressor hose up to it. Make sure the drain valve is closed.
5Turn on the air compressor and allow the pressure to rise to 4 bar. Once the desired level has been reached, close the filling valve using the key on the blanking cap. This should be left for 24hrs to check for any significant drops in pressure.
Change the handing of Ambiente manifolds
Sequence Checklist Completed
1 Reverse the handing of the two manifold bars on their brackets.
2 Remove the mixing valve from the base of the pumpset by undoing the nut that connects the two together.
3 Unscrew the blanking cap from the base of the mixing valve. Note: this has a left-handed thread.
4 Then unscrew the pump connection from the top of the mixing valve. Again, this has a left-handed thread.
5 Rotate the mixing valve through 180 degrees and swap the blanking cap and pump connection around.
6 Remount the mixing valve onto the pumpset, making sure you use the rubber washers provided.
