b) Product description
• The Shower is a remote controlled thermostatic mixer shower for use in domestic properties on a
220 – 240V supply. The mixer (base unit) can be installed in most locations in a house, remote
from the shower cubicle with a single mixed outlet feed.
• The base unit is supplied with cold water and hot water. (Gravity fed on Pumped model, Unvented
on Non Pumped model). The mixed outlet is controlled by a remote control used to adjust the
flow and temperature.
• The remote control is fitted in the shower cubicle along with the shower hose and handset fittings.
• Additional remote controls are available as an accessory if required. (See Page 19).

Installation
a) Introduction
• The remote control thermostatic mixer shower is designed for use as a mixer unit that is sited
remote from the shower cubicle. The shower is controlled using a remote control handset sited
inside the cubicle.
• If the installation involves working at height, ensure that the "Working at Height Regulations
2005" are followed.
(This includes ensuring there is "Proper ladder access", that loft areas are "Boarded down on
joists to and from the installation" and that there is "Adequate lighting", etc).
• The recommended installation sequence is
1. Fix the base unit in its designated location
2. Fix the shower outlet and remote control bracket and all accessories into the cubicle
3. Plumb in the cold and hot water feeds to the base unit
4. Plumb in the mixed outlet from the base to the shower outlet in the cubicle
5. Connect the base unit mains lead to the electrical supply
6. Commission the installation

• The start / stop button on the remote control communicates to the base unit PCB and switches the
unit on and off using the cold and hot and outlet water valves.
(Outlet valve is not fitted on the non-pumped version)
• The warmer and cooler buttons alter the temperature by turning the mixer valve using the stepper
motor.
• The outlet temperature is measured using a sensor and displayed as a digit on the remote control
display.
• The flow buttons change the flow rate by speeding up and slowing down the rotation of the pump.
(On the non pumped version the flow is altered by turning a flow valve using a motor)
• Presets can be used to store favourite settings.
• The remote control display is used to show water temperature, flow rate and battery charge.
