Mira products are precision engineered to provide satisfactory performance provided

they are installed and operated in accordance with the recommendations contained in

this guide.

The shower control is designed for the minimum of maintenance in normal domestic

use. If a malfunction occurs then this will probably necessitate a complete cartridge

replacement.

Important! The cartridge contains no internally serviceable parts.

When installed in very hard water areas (above 200 p.p.m. temporary hardness) your

installer may advise the installation of a water treatment device to reduce the effects

of limescale formation in the heating appliance and spray plates.

Cleaning

Many household cleaners contain abrasives and chemical substances and should not

be used for cleaning plated or plastic fittings. These finishes should be cleaned using

a mild washing up detergent or soap solution, and then wiped dry using a soft cloth.

The light golden colour finish is softer than the chrome finish and its abrasive

resistance much less. When cleaning or using tools during maintenance extra care

must be taken.

Component Interchangeability

Some parts of the latest Mira CombiForce 415 are not interchangeable with earlier

models of the Mira range. Spare parts, where different, are available for earlier

models. Refer to the specific IO&M guide supplied with your shower or contact

customer services for further information (telephone and fax numbers can be found on

the back cover of this guide).

Cartridge Renewal

Should the cartridge require renewal then the following procedure should be followed:

Important! Use only silicone based lubricants when reassembling.

1. Turn off the water supplies and open the shower control to relieve the trapped water

pressure.

2. Prise off the concealing cap, remove the control knob retaining screw/plastic

override stop and the control knob.

3. Remove the two shroud retaining screws and the cover shroud. Note the position

of the adjustable temperature stop then remove. Remove the hub.

4. Undo the four cover retaining screws and remove the cover. (A quantity of water will

be discharged).
