Digital electronic water heater
3.5. Location
The unit is designed to be vertically wall mounted, indoors, in a frost-free environment. When choosing
a suitable location for the cylinder, consideration should be given to the routing of the discharge
pipe to a convenient point and also the availability of an adequate power supply for connecting the
sheathed heating elements.
The wall onto which the cylinder is mounted should be of good sound masonry construction capable
of holding the weight of the cylinder when full of water (see Technical Specifications on page 36 for
weights).
The position of the cylinder should provide easy access for servicing the controls and replacing the
sheathed heating element should the need arise.
Pipe runs should be made as short as possible and lagged to prevent heat loss.
To allow for servicing and repairs, the product must be mounted at least 540 mm above any surface
or object, so that access can be gained to electric connectors and the heating elements may be
removed (see Figure 1).
Figure 1 - Mounting
The unit should be mounted close to an external wall so that the discharge pipe D2 (see Figure 2,
page 7) can be routed to a safe visible place.
The tundish should be mounted in a visible location so that it may easily be inspected.
