INTRODUCTION

Description

The Thermostatic Power Shower is an all-in-one power shower with

an integral mains voltage pump, with separate controls for flow and

temperature. It features a 15mm dual entry push-fit manifold to

enable the appliance to support various inlet supply configurations.

The manifold includes inlet filters and check valves. The

thermostatic mixer incorporates a wax capsule sensing unit and

ceramic disc technology for flow control.

Designed to be surface mounted the Thermostatic Power Shower

comes complete with an adjustable spray handset with three

settings, flexible hose, adjustable slider, soap dish, sliding rail and

bracket.

WARNING!

This appliance must be earthed.

The shower unit must not be connected to a Mains Cold water

supply, Unvented High Pressure systems or Multi-Point/

Combination Gas Water Heaters.

The function of a thermostatic mixing valve is to deliver water

consistently at a safe temperature. In keeping with every other

mechanism, it cannot be considered as functionally infallible and

as such, cannot totally replace a supervisor’s vigilance where that

is necessary. Provided it is installed, commissioned, operated and

maintained within manufacturers recommendations, the risk of

failure, if not eliminated, is reduced to the minimum achievable.

SPECIFICATION

General

Shower unit duty cycle: 15 minutes on, 60 minutes off.

Exceeding the units duty cycle

The motor is fitted with a thermal cut out device, if temperatures

become too high the device will cut the power to the motor but will

self-reset once temperatures have normalised.

Noise Level

The acoustic noise from the pump motor has been reduced with

integral foam/rubber mountings. The type of wall can affect noise

levels. Solid walls will provide quieter operation. At full flow this unit

will produce in the region of 55 dBA measured from a distance of

1m.
