1. Plumbing Connections

appliances and services in the room in

which the shower is to be installed, to

conform to current IEE regulations.

11. All exposed metallic parts in the

bathroom must be bonded together

using a cable of at least 4mm2 cross

sectional area. These parts include

metal baths, radiators, water pipes,

taps and waste fittings.

12. For close circuit protection DO NOT

use a rewireable fuse. Instead use a

suitably rated miniature circuit breaker

(MCB) or cartridge fuse (See table A).

13. In the interest of electrical safety a

30mA residual current device (RCD)

should be installed in all UK electric

and pumped shower circuits.This may

be part of the consumer unit or a

separate unit.

14. A 45 amp double pole isolating switch

with a minimum contact gap of 3mm

in both poles must be incorporated in

the circuit.

15. It must have a mechanical indicator

showing when the switch is in the OFF

position, and the wiring must be

connected to the switch without the

use of a plug or socket outlet.

16. The switch must be accessible and

clearly identifiable, but out of reach of

a person using a fixed bath or shower,

except for the cord of a cord operated

switch, and should be placed so that it

is not possible to touch the switch

body while standing in a bath or

shower cubicle. It should be readily

accessible to switch off after using the

shower.

17. Where shower cubicles are located in

any rooms other than bathrooms, all

socket outlets in those rooms must be

Protected by a 30mA RCD.

18. The current carrying capacity of the

cable must be at least that of the

shower circuit protection (See table

B).

Note: Cable selection is dependent on de-rating factors

.19. To obtain full advantage of the power

provided by the shower, use the

shortest cable route possible from the

consumer unit to the shower.

20. It is also necessary to satisfy the

disconnection time and thermal

constraints which mean that for any

given combination of current demand,

voltage drop and cable size, there is a

maximum permissible circuit length.

21. The shower circuit should be

separated from other circuits by at

least twice the diameter of the cable

or conduit.

22. The current rating will be reduced if

the cabling is bunched with others,

surrounded by thermal loft or wall

insulation or placed in areas where the

ambient temperature is above 30°C.

Under these conditions, de-rating

factors apply and it is necessary to

1. To start the shower

Pressing the start/stop button (Fig.19)

switches on the pump allowing water to

immediately flow through the unit.

2. To stop the shower

Press the start/stop button. This initiate

the Phased (Safety) Shutdown feature.

The Phased (Safety) Shutdown feature

lasts for approx 8 seconds, during which,

the indicator light will flash ON & OFF, the

flow of water will be reduced and the

power to the heating elements cut. This

allows the unit to safely flush out any

residual heat. After which the pump

switches off and the water flow will cease

WARNING: If re-starting immediately

after stopping, be aware that a slug of

HOT water will be expelled for the first

few seconds.

3. To use the power selector

The power selector (Fig.19a) has four

settings – Cold, Low, Medium and Full

power.

'Cold' setting (Solid Blue Symbol):

Is Cold water only. Adjustment at

the temperature control at this

setting will only increase or

decrease the force of the water

from the sprayhead. It will not alter

The water temperature.

'Low' setting (Outline Red Symbol):

Is the low setting for extra economy

during hot months. Temperature

adjustment at this setting is via the

temperature control.

'Medium' setting (Solid Red Symbol):

Is the medium setting for economy

during warmer months and any

temperature adjustment at this

setting is via the temperature
