General Cleaning
Bristan products are made from premium materials, with hand polished, PVD, EPD
or electroplated finishes.
Your shower should be regularly cleaned with warm water, a mild pH-neutral
liquid soap, and polished with a soft cloth. Any residues from soap,
toothpaste, shampoos and shower gels can cause blemishes if not 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.
Operation
Maintenance – Cartridge Cleaning
Unscrew the shrouds. Remove the cartridges and piston.
Remove any O-rings and soak all components in de-scaler and wash off in clean water. Examine all seals and replace if needed. Use WRAS approved silicon based grease on all seals.
Reverse the installation steps, ensuring the temperature stop is aligned correctly
Follow the Temperature Adjustment steps if required.
Troubleshooting
Symptom
|
Cause
|
Remedy
---|---|---
No flow or low flow rate| Partially closed isolation valve.| Open isolation
valve.
Instantaneous water heater cycles on and off as flow rate or pressure is too
low.| Increase water flow rate or pressure through system.
Head of water is below the minimum distance required.| Refer to the
specification for the minimum distance required.
Are the water supply pressures balanced?| If pressures are unbalanced, a
pressure reducing valve should be used for optimum performance.
Hot or cold water being drawn off elsewhere causing pressure changes or
instantaneous boiler temperature changes.| Do not use other water outlets when
using the shower.
Airlock or partial blockage in the supply pipework.| Flush through pipework
and filters to ensure removal of debris and any airlocks.
Hot/Cold water supply has failed| Check the hot and cold feeds. The shower
will not work if either fails.
Maximum Water Temperature too Hot/Cold| Maximum Water Temperature needs
adjusting.| Refer to the Temperature Setting section to set your desired
maximum temperature.
Outlet Water Temperature too Hot/Cold| Filter/pipe blockage| Flush through
pipework and filters to ensure removal of debris and any airlocks.
Installation conditions outside operating parameters.| Refer to the
specification for the minimum distance required.
Hot water temperature is less than 10°C above the required blend temperature|
Adjust hot water temperature or wait for water to reheat if a stored water
system is used.
Instantaneous water not igniting because the water flow rate is too low.|
Increase water flow rate through the system. Refer to the Maintenance section
to clean/check the cartridge and filters for any damage. Contact your boiler
manufacturer.
Instantaneous water not igniting because the water pressure is too low.| Refer
to the specification for system requirements.
