5. Operation
5.1 On / Off - Flow Control
There are two control handles on the shower. Turn the flow control handle (left) anti-clockwise to turn on and increase the flow, and clockwise to decrease and turn off. There is a stop point at the half way point, this is a water saving device to over ride this press in the button and turn the handle past the stop point. When turning off the shower the handle will click when it passes the stop position this is quite normal. The temperature control handle (right) is turned anti-clockwise for hot, clockwise for cold. The maximum temperature is factory set to 48oC.
6. Setting
6.1 The maximum temperature can be adjusted to suit site conditions or user preference. To adjust this, follow this procedure:
6.2 Position the temperature control handle to the maximum temperature point and turn on the flow handle control handle letting the water run long enough to ensure that the hot water supply is at its maximum temperature.
6.3 The shower has been factory set to 38oC at the first stop position with balanced supply pressures of 0.5 Bar.
6.4 Whilst the water is flowing remove the temperature control handle (15), by removing the head cap (17) and unscrew the head screw (16).
6.5 Turn the cartridge spindle (a) until the required maximum temperature is achieved (the spindle many need to be reposition to allow the head to line backup with the stop ring (14) on the shower), anti-clockwise to increase the temperature and clockwise to reduce it.
6.6 Important: Refit the handle so that the stop pin in the handle (15) fits inside the rim of the nylon stop ring (14).
6.7 Push the handle back on and turn clockwise.
6.8 Turn off the flow at the flow control handle.
7. General Fault Diagnosis
7.1 If your valve fails to function correctly, the following should be checked:
7.1.1 Check that the hot and cold connections are the correct way around. Hot on the left, cold on the right when viewed from the front.
7.1.2 Ensure that the hot water temperature is adequate. The recommended minimum temperature is 60°C.
7.2 If your shower will not turn off:
7.2.1 Check ceramic disc valve (12) is free of debris.
7.3 If your shower has a low flow rate.
7.3.1 Check that the filters (6) are not blocked.
8. Cleaning & Maintenance
8.1 Cleaning
Your fitting has a high quality finish and should be treated with care to preserve the visible surfaces. All surface finishes will wear if not cleaned correctly, the only safe way to clean your mixer is to wipe with a soft damp cloth. Stains can be removed using washing up liquid. All bath cleaning powders and liquids will damage the surface of your fitting, even the non-scratch cleaners.
8.2 Regular Maintenance
We advise that the valve is regularly serviced, particularly in hard water areas. It is also important to clean the handset regularly in hard water areas to maintain an even spray/flow of water.
NOTE: ISOLATE THE WATER SUPPLY TO THE SHOWER VALVE.
8.3 Cartridge Removal (See Fig. 1b)
8.3.1 Remove the temperature control handle (15), by removing the head cap (17) and unscrew the head screw (16).
8.3.2 Unscrew the cartridge (13) anticlockwise out of the body.
8.4 Cartridge Maintenance
8.4.1 Place the cartridge in a bowl and carefully add some hot water (just off the boil) and vinegar to de-scale the cartridge. Leave until the water has cooled.
8.4.2 Then remove the cartridge and rinse with clean water.
8.5 Refitting the Cartridge
8.5.1 Grease the seals with suitable silicon grease and carefully refit the cartridge into the body.
8.5.2 Reset the maximum temperature and refit temperature handle
