Page 3: Introduction
INTRODUCTION The Mira Vigour Thermostatic Power Shower is an all-in-one power shower with an integral mains voltage pump and separate controls for flow and temperature. It features a 15 mm dual entry push-fit manifold which supports various inlet supply configurations. The manifold includes inlet filters and check valves. The thermostatic mixer incorporates a wax capsule sensing unit. -

Page 11: Installation
INSTALLATION General Do not take risks with plumbing or electrical equipment. Do not install the shower unit in a position where it could become frozen. Isolate electrical and water supplies before proceeding with the installation of the shower unit. The shower unit must be fed from a cold water storage cistern and hot water cylinder with equal pressures. -
Page 12: Plumbing
Plumbing A minimum storage capacity of cold water of 230 litres (50 gallons) is required to provide adequate showering time. Insufficient storage may result in the pump being run dry. Layout and sizing of pipework must be such that nominally equal inlet supply pressures are achieved and the effects on the shower performance of other draw-offs are minimised. - Page 13 Warning! Do not fix the shower unit to the wall until plumbing and electrical installations have been completed. Decide on a suitable location for the shower unit avoiding buried cables and pipes. The unit should be positioned at a height convenient for all the family (at least 200 mm below the ceiling to allow for the fitting and removal of the unit cover).
- Page 14 Make sure that the end of the supply Chamfer pipework is cut squarely and is free from burrs, which will damage the inlet manifold seals. Chamfer the end of the pipe to assist insertion into the fitting and prevent the ‘O’ seal tearing. Warning! Do not insert fingers into the push-fit connectors as this can result in injury.
- Page 15 Temporarily locate the shower unit. Position the shower unit on the wall and mark the three fixing points. Note! Installers may wish to obtain alternative proprietary cavity fixings for dry lined, stud partition or dry partition wall structures. Use the push-fit release tool to push the grey collars into the manifold to release the shower unit from the supply pipes.
- Page 16 12. Fit the three rubber feet into the Rubber Feet recesses in the rear of the case as shown. The feet will reduce the noise transmitted by the power shower through the wall. Warning! Blanking plates should be fitted to stop water ingress into the inside of the unit.
- Page 17 14. Locate the shower unit on the inlet supplies and push the inlet manifold onto the pipework until resistance is felt. DO NOT FORCE! Note! PTFE tape or liquid jointing compound must not be used and is not required to assist connection. 15.

Page 19: Commissioning
COMMISSIONING The unit must not be run dry. Before proceeding any further with the installation the shower unit must be commissioned. Connect the flexible hose to the outlet of the shower unit. Caution! Do not over tighten. Hose Washer Hose Turn on the water supplies and check for leaks. -
Page 20: Maximum Temperature Setting
Maximum Temperature Setting It may be necessary to adjust the maximum temperature for site conditions to make sure of safe showering from the unit. Make sure that the hot water temperature is at least 12 °C above the required temperature for correct operation of the thermostatic power shower. - Page 21 Caution! When resistance is felt DO NOT USE FORCE to turn the spindle any further as this is the maximum shower temperature obtainable with the available hot water storage temperature. FORCE will DAMAGE the internal components. Turn the temperature spindle until the maximum water temperature required Temperature Spindle is obtained.

Page 22: Disabling The Temperature Override Button
Disabling the Temperature Override Button The temperature override button allows the user to override the preset maximum temperature. The temperature override button should be disabled if the power shower is to be used by the young, the elderly, the infirm, or anyone inexperienced in the correct operation of the controls. -
Page 23: Operation
OPERATION For safety reasons this appliance is fitted with an adjustable maximum temperature setting. This must be checked and adjusted as necessary to suit both site conditions and user’s comfort.
