Electrical Installation

The Schematic arrangement of the wiring within

the PulsaCoil Stainless is shown above.

The whole of the electrical installation shall be

designed and installed by a competent person

fully in accordance with the latest edition of the

Requirements for Electrical installations BS 7671.

The PulsaCoil Stainless appliance is provided

with two side entry 3kW immersion heaters and

has been designed to generally operate with an

off peak supply.

The lower immersion heater heats the whole of

the contents and is normally connected to the

off peak supply.

The upper immersion heater is positioned at

a level on the PulsaCoil Stainless to heat the

top 66 - 111 litres of the store - see Technical

Data Table on page 5. This is connected to the

unrestricted on peak supply and is switched

manually by the householder using the button

provided on the front of the appliance. When

pressed the on-peak boost will remain active

until the next time the off-peak becomes

available (unless switched off again manually).

The size of the appliance and the need to use

the on peak boost facility is reduced if a better

off peak tariff can be agreed with the electrical

supply company - see Model Selection Guide

on page 5.

Wiring The PulsaCoil With A Split Consumer

Unit I.e. Separate On And Off Peak Supplies.

Historically this has been the typical supply

method and no special wiring arrangements

are required.
