GENERAL PREPARATION
1. Prepare an opening in the wall approximately 1 metre above the ground.
The opening requirements are Height 1030 mm, Width 390 mm and a
minimum Depth of 160mm (see dimension diagrams page 3). Ensure the
location complies with the requirements of AS/NZS 5601 Fig. 6.2.
2. Remove the transport tab (1) from the pipe entry point of the Insert.
3. Determine the appropriate electrical access point and remove either the
left or right the knock out plug (2)located near the bottom of the side
walls of the Insert.
SECURING OPTIONS
The Smart Box Insert is designed to be surface mounted and may be
secured using one of the following methods:
(A) Securing the Smart Box Insert externally
Secure to the wall surface via the 8 screw holes provided in the ange of the
Insert using suitable fasteners.
(B) Securing the Smart Box Insert internally, through the side wall
Secure the Insert into a solid xture such as brickwork, timber studs etc,
through the side walls using suitable fasteners.
At least two fasteners should be used through each side wall approximately
125 mm from the inside top and bottom horizontal faces of the Insert.
Excess space between the side walls of the Insert and the
solid xture may require packing to prevent distortion of the
Insert.
(C) Securing the Smart Box Insert internally, through the rear wall
Install two noggins (E) between wall studs (F), these are to be centred at
130 mm from the top and bottom of the opening. Secure the Insert into the
noggins (E) through the rear wall using suitable fasteners.
(D) Securing the Smart Box Insert with the use of a brick tie
Secure a brick tie to the side walls of the Insert with pop-rivets or screws.
As the brickwork is being laid use the attached brick ties to secure the Insert
into the brick courses. Use two brick ties per side, one near the top and
bottom of the Insert.
(G) Installing the Smart Box to rendered surfaces
Use spacers (G) (not provided) to install the Smart Box Insert, with sucient
clearance for rendering.
When the render is applied ensure that the gap provided by the stand-o spacers is NOT exceeded as
this will prevent the Smart Box Cover from being tted!
