Installation Instruction
General Instructions:
- This product must be installed by a licensed plumber. Ensure that your plumbing installation conforms to the Australian/New Zealand Standard AS/NZS 3500.
- All pipework must be thoroughly flushed prior to the installation of the shower. In-line filters must be fitted on both hot and cold supplies to prevent foreign particles from damaging the shower components.
- Ensure that all outlets used for personal hygiene deliver water at a safe temperature in accordance with regional regulations.
- Verify that the water pressure is within the recommended range for the shower to function properly.
Bottom Divertor Installation
1. Ensure that the G1/2 outlet thread is at the correct length, trim the outlet if necessary to achieve the desired fit.
The recommended height for the water inlet is 700mm from the finished floor surface.
Apply the G1/2 water outlet connection with Teflon tape to ensure a watertight seal.
2. Locate the wall studs and ensure that at least one bracket is anchored into a stud for secure installation.
Position the wall seal or mounting bracket at the specified height, centered over the stud.
Mark the hole positions on the wall using the diagram above as a reference.
3. Drill pilot holes into the wall stud to a depth of approximately 60mm, ensuring the holes are suitable for the mounting screws (and wall plugs if necessary).
Tip: Use a 3mm drill bit for screws into timber, or an 8mm drill bit if using wall plugs.
4. Apply a small amount of silicone to the back of the mounting bracket, focusing on the area around the screw holes.
5. Install the mounting brackets by securing them to the wall with screws.
Tip: Ensure you use the appropriate mounting screws for the specific wall stud material. The provided screws are designed for timber wall studs.
6. Insert shower arm into shower rail, firm it with grub screw, do not over tighten the screws.
7. Screw the adapter onto the prepared outlet thread.Slide the backplate onto the divertor and attach the divertor to the water inlet and secure it in place.
Mount the shower brackets onto the wall at the desired height along the shower rail.
Once both brackets are securely mounted, tighten all
the grub screws on the shower rail and the diverter to ensure everything is firmly in place.
Attach the hand shower to the hose and connect the
hose to the shower rail, ensuring that rubber washers
are in place at both connection points to prevent
leaks.
8. Verify that each connection is securely tightened.
Turn on the drainage system and water supply, and
inspect all connections for any signs of leakage.
