TROUBLESHOOTING

cleaner may be used on external surfaces of the handset. Rub-clean showerheads may be rubbed lightly to remove scale as required. Over time build-up of limescale requires the showerhead to be cleaned more thoroughly, as follows.

1)Use a liquid non-abrasive bathroom cleaner on external surfaces of the handset.

2)Engage the key into the spray cartridge recesses and turn anti-clockwise to unscrew.

3)Remove the two small black ‘O’ rings from the rear of the spray cartridge, and rinse the ‘O’ rings clean.

4)Brush the spray plate with a stiff bristled brush, if necessary immerse and soak the spray plate for several hours in a proprietary limescale remover. Rinse off all traces of limescale and limescale remover from the showerhead.

5)Replace the two black ‘O’ rings on the rear of the spray cartridge and refit the cartridge to the showerhead tightening with the key.'

SECTION 6

Trouble shooting

Before calling our customer service department please use the table to determine likely causes of the problem:

NOTE Under normal operation the shower heats the water as it passes through the unit. The temperature of the water is affected by the temperature of the water in the mains cold water supply and the

speed with which the water flows through the unit. It is therefore normal for the water coming out of the shower to change temperature through summer and winter months where the mains water temperature changes. It is also normal for the water temperature to vary when other water appliances are being use in the home as these vary the water flow to the shower unit. Do not under any circumstances cover the showerhead

or prevent or restrict water leaving the showerhead or unit. It is important to keep the showerhead clean, removing all lime scale and any other dirt blocking the holes of the showerhead. The showerhead must be cleaned as described in section 5 ‘looking after your shower’.

SECTION 7

Maintenance

Disconnect from mains electricity supply before removing front cover.

All maintenance should only be carried out by a qualified service engineer.
