Installation options
There are two methods of installing the Inground 200:
1. Installation sleeve
2. Direct burial
1. Installation sleeve
Use of an installation sleeve is recommended for hardscape locations (tarmac, stone paving, etc.)
and in landscape locations where the Inground 200 groundwork may be subjected to loads from
pedestrians or vehicles (including grasscutting or gardening equipment, motorcycles, emergency
services, etc.). Use of an installation sleeve will also allow work to be carried out in two stages:
1. Pre-installation (excavation, conduit-laying and groundwork preparation). This can be carried out
by construction personnel.
2. Installation (cable pulling and connection, fixture installation and adjustment). This must be
carried out by qualified electrical personnel only.
A steel installation sleeve for the Inground 200 is available (contact your Martin Architectural dealer
or see the Martin Architectural website at http://www.martin-architectural.com for full details). The
Inground 200 in a correctly installed drive-over installation sleeve will support a weight of 5000kg
from a vehicle tire.
Sleeve installation: example
The example installation below shows how adequate support and drainage can be achieved, but the
installer must make allowance for local conditions:
Temporary installation sleeve cover
To avoid rainwater and dirt gathering in empty installation sleeves while waiting for the Inground 200
to be installed in them, a temporary cover is supplied with each sleeve.
Important! The temporary installation sleeve cover is not designed to support weight, so ensure
that pedestrians and vehicles are kept away from the sleeve by using warning
notices and barriers.
2. Direct burial
Burying the Inground 200 directly in sand, gravel or shale, etc. is suitable in landscape installations
only. While the fixture itself will bear up to 5000kg (11,023lb), groundwork in direct burial
installations is unlikely to remain stable if loads are applied to the fixture. Therefore, in all hardscape
