General Cleaning

Bristan products are made from premium materials, with hand polishing and electroplated finishes.
Your taps or shower should be regularly cleaned with warm water, a mild pH- neutral liquid soap, and polished with a soft cloth. Any residues from soap, toiletries, etc. should be rinsed off straight after use.
Household bleaches and cleaners contain harsh chemicals and may damage the surface finish. Avoid using abrasive cloths, scouring pads, scrub sponges, steel wool, or anything similar.
Some surfaces such as nickel and pewter may be affected by the dye found in some cloths, so it is also important to avoid hanging cloths on spouts.

Operation

Wall Outlet Installation

Choose the location for the wall outlet and create a 25-30mm hole in the wall.
Ensure your shower accessories have enough reach from that position.
Finish the wall surface.

With rear access
Fit the wall outlet, ensuring the washers have fitted either side of the wall.
Go to Step 6 in the Installation Steps.

Servicing Intervals
To reduce the build-up of lime scale and to ensure this shower works to its maximum performance we recommend this shower is serviced every 6-12 months depending on the hardness of your water.

Without rear access

Follow Step 6 in the Installation Steps, fitting a 1/2” female connection at the hole in the wall (not supplied).
Screw the wall outlet into the 1/2” female connection, using a suitable thread sealant ensuring the rubber seal is fitted to the back of the wall outlet.

Maintenance – Cartridge Cleaning

1. 

2. Gently remove the concealing plate from the wall.

3. Unscrew the shrouds.
   Remove the cartridges and pistons.

4. Remove any O-rings and soak all components in de-scaler and wash off clean water. Examine all seals and replace them if needed. Use WRAS-approved silicon-based grease on all seals.

5. Reverse the installation steps, ensuring the temperature stop is aligned correctly.

6. Follow the Temperature Adjustment Steps if required.
