5. Before installation

5.1 Installation regulations

5.2 Installation requirements

The unit should not be used in association with any of 

the following:

 

`

Water supplies that have either inadequate 

pressure or where the supply may be intermittent. 

(Minimum dynamic pressure 0.5 bar).

 

`

In areas where the water consistently contains a 

high proportion of solids, e.g. suspended matter 

that could block the strainer,  unless adequate 

filtration can be ensured.

 

`

In areas where the water supply contains chloride 

levels that exceed 250mg/L.

For information or advice regarding any of the above 

contact Technical Enquiries on: 0344 871 1535.

 

The unit can be connected directly to the water 

supply source provided that a minimum dynamic pressure  

of 0.5 bar and maximum pressure of 10 bar. If the measured 

inlet pressure exceeds this value then a pressure reducing 

valve  must  be  fitted,  this  is  available  through  Heatrae 

Sadia's supply partners.

5.3 Transport and storage

If the unit has to be stored prior to installation, it must be 

in a secure area free from frost, excessive dampness 

and humidity.

5.4 Choice of location

The unit must be vertically wall mounted and the 

following points should be considered:

The unit should be sited to ensure minimum dead leg 

distances, particularly to the point of most frequent use. 

However there should be a minimum height between 

the hot water outlet and the highest draw off point, 

outlet tap, of 1.2 meters.

Avoid  installations  where  extreme  cold  temperatures 

will be experienced. All exposed pipe work should be 

insulated.

The breather pipe work from the top of the unit should 

have a continuous fall, and ideally vent to an outside 

wall in a safe manner via the tundish supplied. 

Access to associated controls must be available for the 

servicing and maintenance of the system, the heater 

requires access from the front and underside for this 

purpose, refer to figure 6 page 12. Ensure that the wall 

the unit is mounted on, is perpendicular and capable 

of permanently supporting the weight when it is full of 

water s

ee Table 1 on page 6 for the unit weights.

5.5 Positioning and access

It is important that as much access available is 

provided around the unit as is practical. In the event 

of a component failure, full access to the front and 

underside of the unit is required for servicing. A 

minimum of 150mm above the top of the unit must be 

kept clear for access, refer to figure 6, page 12. 

Access to all isolation valves and control valves in the 

water circuits, both hot and cold are also required for 

normal operation and servicing.

WARNING

Installation of the appliance must be carried 

out  by  a  qualified  engineer  in  accordance 

with prevailing and national regulations as 

listed below.

 

`

Building Regulations

 

`

The Building Standards (Scotland)

 

`

The Building Regulations (Northern 

Ireland)

 

`

I.E.E Electrical Regs

 

`

UK Water Regulations

WARNING

 

`

In the unlikely event that water from the 

unit should vent from this breather pipe 

then the water could be at an excessive 

temperature  exceeding  95  degrees. 

Therefore it is essential that the 

breather pipe work selected is capable 

of withstanding this temperature and 

must have no obstruction and allow free 

and safe passage for this hot water.

CAUTION

 

`

Ensure that the unit is correctly 

positioned. Consideration should 

be given to the access and space 

requirements for operating and 

servicing the unit.

 

The breather pipe assembly at the top can be 

positioned on either the left or right.
