Clear any build up of clay from around the hole to allow the truck to reverse to within one metre of the hole. © In very wet conditions, it is best to leave the last few bucketfuls to be dug when the truck arrives. If the ground is rocky, it is advisable to dig the hole ahead of time to minimise delays on -site. 0 Ensure there are no power lines or other hazards above the excavation site. © Ensure that there is solid ground for the stabilising "jacks" to stand on. Do not dig trenches where a jack will need to stand. 0 We recommend an inspection chamber (AJ) be fitted just before the BAF Unit for maintenance.

If in doubt, we can hold off on commissioning the system until the landscaping is finished and fit extra risers if required. 0 Our driver will leave sufficient 7 -Core Cable to reach the house. Our technician will commission the system by installing the air blower, water pump and electronic controls and wiring them at the system. He will leave the "internal panel" for connection by your electrician to the mains with the most senior person on site.
