Construction job
• The aperture prepared for the strongbox must be at least 10 cms wider all round
than the box. The security of the box depends on the strength of the installation
works.
• Dampen the hole created for the box.
• Having previously removed the door, now leave the sealing assembly in place
(parts 1 and 3). This is to avoid dust and dirty entering the strongbox and the
opening system.
• Screw the 4 security fixing arms (6) into the security fixing ring (Fig.1)
• Place the strongbox into the prepared hole and check the position is is stable
EN both vertically and horizontally.
• Prepare a 3 of sand to 1 of cement mortar mix (we do not recommend the use of
quick-dry cement). Carefully fill the hole around the strongbox, ensuring the box is
completely embedded in the mortar. Make good the work leaving the waterproof
lid in place . The lid can be easily cleaned on completion of the installation.
• Once the filling is complete tamp or vibrate the mortar to eliminate any air
pockets.
• Leave the strongbox open until the mortar is completely dry. This is to avoid any
condensation inside the box.
• Use the box when the work is completely dry.
