An MCB from the client’s fuse board will supply the power to the Septech 2000 Control
Panel. If an RCBO is installed in the fuse board the MCB should receive the power from
the Primary side of the RCBO, not power from the secondary side of the RCBO.

Installation:
1. The excavator must be on site on morning of
delivery. The client must indicate the level
of the inlet pipe at the hole. If ground
conditions are dry, the hole can be dug
before our installation personnel arrive.
Where the conditions are wet, the hole
should only be excavated through the dry
material and not below until the installer
arrives. The level of rock on the site (if any)
should be noted during the percolation test
trial hole excavation. The client must have
adequately sized rock breaking equipment
where required. All excavation is the
responsibility of the client.
2. The installer will explain the levels for the
bottom of the hole as per Fig. 2
3. The truck arrives and the installer places the
tanks in the hole with the truck mounted
crane. The installer will assemble the interconnecting pipework and carry out the
wiring of the tanks. The excavator may be
required for backfilling at this stage. The
excavation must be backfilled on the day of
installation.
4. The installer will leave the required amount
of cable to run back into the house/garage.
The control panel will be left with the most
senior person on site and this should be kept
for the electrician for fixing and wiring.
When the lids are on the tanks and the
backfilling is complete, the installer is
finished.
Note :
Please have a mobile number for the excavator
driver the evening before the installation.
Please indicate before the day of installation
the level from the top of the finished
ground to the invert of the inlet pipe. This is
important to allow enough risers to be
placed on the tanks.
Percolation Area:
1. For the percolation the following items are
required.
Approx. 50m of
normal gauge hydradare pipe
Minimum 1 no. 1_” Philmac Tee.
Minimum 20 tonnes 20-30mm clean round
stone.
2. Check the planning guidelines for the
required length of percolation pipe and
whether the percolation is sub-surface or a
raised bed.
3. The outlet pipe of the Septech ends in a
connector for the 1_” pipe. The percolation
installer joins onto this pipe but only starts
the stone when the percolation area is
reached. Do not start the stone at the outlet
from the Septech.
4.
The percolation trenches should be
constructed similar to Fig. 1 & Figure 3. The
two inspection pots at the end of the pipe
will arrive with the Septech.
Notes:
The inlet pipe into the Septech must be
connected by the builder/owner.
Commissioning:
Normal use in a house will take 1-2 weeks for
the tanks to fill up. When the tanks are nearly
full the system is ready to be commissioned.
This involves the Service Engineer checking the
installation and turning on the power. The
Septech warranty commences at the time of
commissioning.
