User guide - Shower valve operation
Your Opto shower system has been designed to provide many years of trouble-free use when installed and operated correctly.
Concealed valve operation
1 Turn the front on/off knob FULLY anticlockwise into the open position to turn the shower on.
Turn the on/off knob fully clockwise into the closed position after use.
Please note the on/off control knob MUST NOT be used as a method of flow control .
2 When the temperature lever is in the vertical position the valve is in the mid-blend position.
The mid-blend temperature is dictated by the temperature of the incoming supplies.
To select a comfortable showering temperature, slowly rotate the temperature control lever clockwise to
increase the temperature and anti-clockwise to reduce the temperature, using the temperature markings
as a guide.
Exposed valve operation
1 Turn the shower on by turning the on/off knob on the LEFT of the valve when viewed from the front FULLY
on into the open position by rotating the knob in an upwards and over direction until a stop is reached.
Turn the on/off knob fully off into the closed position after use, again in an up and over direction until a
stop is reached.
Please note the on/off control knob MUST NOT be used as a method of flow control .
2 When the temperature lever knob on the RIGHT of the valve, when viewed from the front, is in the forward
facing position the valve is in the mid-blend position. The mid-blend temperature is dictated by the
temperature of the incoming supplies. To select a comfortable showering temperature, slowly rotate the
temperature control lever upwards to increase the temperature and downwards to reduce the temperature,
using the temperature markings as a guide.
Shower valve cleaning and maintenance
Your Opto shower valve should be cleaned using only a soft cloth and washing up liquid.
DO NOT USE ABRASIVE CLEANERS.
This Opto shower valve requires minimum maintenance, even in hard water areas. In order to ensure the internal working parts are
unaffected by any water borne deposits, the following procedure should be adopted regardless of whether the shower is in regular
use.
Once a week with the shower fully running, rotate the temperature control lever from full hot through to full cold 5 or 6 times to
activate the internal cleaning mechanisms.
