2. Make sure the nut sits in the bracket of the SBOX with a washer either side.
Then tighten the nut to the bracket to secure the SBOX.
3. Note: Make sure before fastening the nuts, the SBOX is level. See Fig. 4-3.

5. ARRANGEMENTS FOR DRAINAGE PIPE
5.1. SBOX drain pipes installation
1. Please use the flexible drainage pipe to connect the SBOX drainage
port and the PVC pipes, and use the snap ring for fastening.
2. Then connect PVC with solvent weld to complete the drainage.
3. To avoid water flowing back into the SBOX, ensure the drain has a
fall of 1/100 away from the SBOX.
4. While connecting drains, make sure the gravity drain doesn't exceed
20m. If drain termination cannot be done within 20m, install an
external pump. Make sure the drain is supported every 800mm
(dependant on quality of drain pipe). Ensure no dips are in the drain.
5. Follow fig 5-2 for connecting multiple units on one drain.
6. The termination of the drain pipe should be terminated 50mm
above the ground. When installing make sure a dry trap or U bend
is installed. This will prevent smells and water returning back up the
drain.

to make sure there are no dips in the drain. Make sure all drain
have been sealed.
1. Use a water main to fill the water tank with 500~1000ml water.
2. Check to see if the water has drained away. If not repeat the process or
re-install.
