SITING OF THE SHOWER

SITING OF THE SHOWER

The installation must be in accordance with 

Water Regulations/Bylaws - 

see page 7 and 

below for water specifications.

•  To ensure activation of the heating elements, 

the shower must be connected to a cold 
water supply which is gravity fed from a 
static cold water storage cistern with a 
minimum capacity of 114 litres (25 gallons) 
that will deliver a 

MINIMUM

 of 8 litres per 

minute to the shower water inlet.

•  There must be a maximum head of water of 

10 metres and a minimum head of 8 cm as 
measured between the bottom of the cistern 
and the top of the shower unit. There must 
be no other cold water draw-offs between 
the cistern and the unit and the pipe must 
not supply water to any other tap or fitting 
at a lower level.

•  Pipework to the shower unit 

MUST

 be 

routed where it remains below the level of 
the water cistern.

•  If it is intended to operate the shower at 

pressures above the maximum or below the 
minimum stated, contact Customer Service 
for advice.

•  If the stated flow rates are not available,  

it may not be possible to achieve optimum 
performance from the unit throughout  
the year. 

•  During periods of high ambient temperatures 

it may be necessary to select the economy 
power setting to achieve your preferred 
shower temperature.

Fig.5

 shows a typical system layout.

•  Refer to 

fig.6

 for the correct siting of the 

shower. Position the unit where it will 

NOT

 be in direct contact with water from 

the showerhead. Position the shower unit 
vertically.

•  Allow enough room between the ceiling and 

the shower to access the cover top screws.

•  Mark out entry points and routing of the 

water and electric supplies into the shower.

ADVISORY NOTE

The supply pipe from the cistern should be 

on the opposite side to the float operated 

valve to prevent air being drawn into the 

pipe when the cistern is filling.

If it is intended to operate the shower in 

hard water areas (above 200 ppm temporary 

hardness) a scale inhibitor should be fitted.
