Assembling the sandbox
If the sandbox is already assembled then skip to Chapter 5.
All of the tubes are connected and tested for leakage before delivery.
Take care not to break the tube connections while unpacking.
Construct the sandbox using the following instructions (numbers refer to Figure 1).

Before setting up the sandbox
Before the sandbox is assembled, the plastic drainage pipe (4) inside the box (1) must be covered with filter
cloth. The supplied filter cloth has two layers, and is 6 cm wide. The plastic drainage pipe needs to be covered
by 3 layers of cloth to disperse the suction, and to stop sand from blocking the pipe’s holes when this suction
is applied.
To apply the filter cloth to the pipe, the following steps should be followed:
1. Cut a 3.5 m long section from the supplied roll of filter cloth.
2. Cut down one side the filter cloth to make a single 12 cm
wide layer (Fig. 2).
3. To knot the cloth to the pipe, a 10 cm long section is cut into
the end of the strip to form two ties (Fig. 3)
