3INSTALLATION OF A PLUS+CONTROLLER STOOL
3.1 Installation of a Plus+ Cabinet Stool Frame
1. Refer to Figure 2 for the general method of installation and dimensions.
2. Excavate a pit in the ground approximately 100cm long x 70cm wide x 450cm deep.
3. Locate and prepare the ducting to enter the controller base in a suitable position, Figure 3.
4. Create a flat level base layer either with concrete or a flagstone of at least 900mm x 600mm
embedded securely at the bottom of the pit.
5. Remove the Sealed Base Kit, Step 1 Figure 2 from the top of the stool and set to one side
being careful not to damage any studs or lose any fixings and keeping the kit in the protective
bag provided.
6. Place stool into the centre of the level base layer. Note - It is essential that the stool is fitted
at the correct height and that the access door can be accessed. Make sure that the stool
door is facing the same way as the cabinet door will open. Adjustment may be required
to ensure that the outer case sides are vertical; this should be checked using a spirit
level on the stool surfaces.
7. Mix up a stiff mixture of concrete (mix: 1 cement, 3 sand, 4 coarse aggregate (20mm) with
no excess water) and cover the base layer/ flagstone and stool legs to a height approximately
100mm (4") above the bottom of the stool. Note - Cables already entering the pit must be
held away from the wet concrete. Where there is a risk of freezing, then a suitable
antifreeze additive shall be incorporated in the concrete mix to ensure proper curing.
8. Using suitable sized cut paving slabs or similar, shutter all around the stool to prevent
concrete from entering the area within the stool, Figure 4.
9. Backfill around the stool with more concrete or other suitable material substrate, Figure 5.
10. Make good up to the surface level with asphalt or other material to match original surface.
11. If the cabinet is not going to be installed to the stool at the same time then the stool must be
capped to ensure it is safe to leave by bolting the Sealed Base Kit back to the stool, Step 3
Figure 2. Note - Ensure that the studs are facing downwards. If the Sealed Base Kit
