Electrical Installation

The upper immersion heater is positioned at a level on the PulsaCoil

approximately 50 litres of hot water - seeTechnical DataTable 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.

A-CLASS

Although the PulsaCoil

peak supply it will also operate quite successfully if it is only supplied with an on peak

supply. However, this will substantially increase the running costs of the appliance and

should only be considered if an off peak supply is not available.

To allow the appliance to operate successfully with on peak only supplies, two separate

16A 230V 50Hz supplies MUST be provided with one wired into the on peak connections

in the normal way and the other wired into the off peak connections.

A typical method of providing a typical arrangement of on and off peak electrical supplies

is shown below for information. - if unsure please consult Gledhill Technical Department

for further assistance.

The two switches must be clearly labelled for the householders use.
