INSTALLATION OF AIR HOSES AND EXTERNAL CONTROLLER
* Must be installed within 18m of tank. (Air hoses are 20m in length)
Selecting the location
• The location must be protected from direct sunlight
during the summer.
• The rear side of the cabinet must be installed with at
least 10cm clearance from the nearest wall to allow for
sufficient ventillation.
• The air hoses must be no longer than 20m.
• The cabinet must not be installed in ground water.
This also applies to groundwater or backwater that
occurs only occasionally.
1
Installing the cabinet in the ground and
connecting the service duct
Excavate a hole of sufficient size for the cabinet (installation
depth 50cm). Only coarse excavated soil that is free from
stones may be used as backfill material is unsuitable, round
gravel should be used (size 8-16mm). Make sure the cabinet
is stable and is installed vertically in the excavation.
Push the 110mm pipe through the seal in the bottom of the
cabinet. Fit a 45 degree bend to the end of the pipe inside
the cabinet with the open end facing upwards.
2
Inserting the underground power supply cable
Drill a 20mm diameter hole in the side of the base section
of the cabinet at a suitable position for the armoured power
cable to feed through. Fit the M10 x 1.5mm cable gland
(suitable for a cable diameter of 8-13mm).
3
Electrical connection
The electrical connection must only be carried out by a
qualified electrician. An underground armoured cable must
be laid to supply power to the cabinet. This cable must be
protected by a 13 amp fuse from the building installation
and must be fitted with an isolated switch for repair and
maintenance. The underground cable is connected to the
pre-assembled power socket in the cabinet. This power
socket can be removed for easy assembly by unscrewing the
two nuts from the holding plate.
