These instrucons describe the installaon, assembly, operaon, maintenance and fault nding of the Hiper Heat
Interface Unit (HIU). For operaon of the enre plant, the technical documentaon of all the components used
such as, boiler, tank, pumps, pipework and valves must be complied with. Inta does not accept any responsibility for
the design and performance of the heat network or components outside of the HIU.
Installaon should only be carried out by a qualied and competent plumbing installer and a qualied and
competent electrical installer in accordance with the current Building, Water and Electrical Regulaons, Legislaon
and Standards. Do not start installaon unl you have thoroughly read and understood these Assembly and Oper-
ang Instrucons and have complied with all safety provisions.

SECTION 1 - Important informaon and introducon
Heat Interface Units (HIU) deliver heat generated from a centralised heang plant to mulple homes,
apartments or ats. The Inta Hiper HIU interfaces the heat network and dwellings systems through plate heat
exchangers and a control valve regulates the supply of heat to provide hot water (DHWS) and room heang (HTG) to the
dwelling. The Inta Hiper HIU has been developed to this concept with unique control
features to opmise its performance and operaon.
Heat from the main boiler plant is transferred to the home by two plate heat exchangers. One plate heat exchanger (PHE)
provides the hot water supply (DHWS) and the other plate heat exchanger supplies the central heang circuit (CH).
This can be by either radiators or underoor heang, the installer has the opon to commission for either.
HIUs do not generate their own heat so to deliver DHW and CH most suitable for the requirement of the home or apartment it
is the responsibility of the installer and or system designer that the heat network delivers heat at
sucient ow rate and temperature to do so.

Accessories - ‘First Fix Jig’
The installaon plan may require pipe work to be made up to the
posion where the HIU is to be installed, but at this stage not involve
installing the HIU itself. At this ‘rst x’ stage not having the HIU in
posion eliminates risk of damage or even vandalism while the
property is not secure.
Using the Jig allows pipe work to be installed without the HIU and
saves the cost of the purchase of a ‘rst x rail’ for every HIU.
This simple method allows the wall bracket, pipes and isolaon valves
to be posioned. Then the Jig is removed, and the installer moves to
the next installaon and so on, unl all rst x pipe work is in place,
and allowing other trades on site to carry out their work. The HIUs
can be installed simply on to the wall bracket and connect to the
isolaon valves at a planned later date.
5.1 Before installaon read and comply with the following
Comply with all safety provisions.
The Installer’s Responsibility -in accordance with Part L of the Building Regulaons, all hot and
cold water pipes should be labelled and insulated to the current standards.
Installaon should only be carried out by a qualied and competent plumbing installer and a qualied and
competent electrical installer in accordance with the current document Building Regulaons, Legislaon
and Standards.
It is the installer’s responsibility to ensure that the place of installaon and wall is suitable.
An unsuitable locaon or provision of adequate supplies (Primary Heang and Cold Water mains) will not
jusfy any warranty or fault claim;
• The wall must be capable of bearing the weight of the HIU lled with water permanently
• Locaons where access is restricted for maintenance, see page 3.
• The HIU is only for WALL MOUNTING in the orientaon shown in this manual.
• Locaons where criminal damage or illegal tampering cannot be reasonably preventable.
• Locaons where discharge pipe is not able to be safely or legally installed and connected
• Supplies which are not suitably clean, and free from contaminants.
• Supplies which contain chemical contaminants.
• Supplies with inadequate ow or pressure (less than 1.5 bar)
• All cold and hot water pipes must be labelled and insulated in line with Part L of the
Building Regulaons
Cold water mains supply should be protected from excessive high pressures.
A Pressure Reducing Valve is recommended and pre-set to 3 bar.
• Wall xing bolts are to be provided by the installer and be suitable to bear the weight of the HIU perma-
nently when full of water.
• The posion of the HIU should be where the pipe run lengths to DHW outlets are kept to a minimum.
SECTION 5 - Installaon

5.2 Consider which installaon method is to be used.
1. HIU as delivered to site.
2. HIU and stand o brackets as delivered to site
3. HIU JIG at First Fix Pipe work stage, with the HIU to follow later.
4. HIU JIG and stand o brackets, with the HIU to follow later.

5.3 General installaon notes
• Ensure all hot and cold water pipes are labelled and insulated in accordance with Part L of the build-
ing regulaons.
• The HIU can only be installed in one orientaon, with the heat network connecons at the top, and
in a vercal posion.
SECTION 5 - Installaon
05/20 E&OE

5.4 Ensure the chosen installaon site is inside the building, weather proofed and provides good access for mainte-
nance, minimum requirements as on page 3. Note where and which pipe connecons will be
Required, and pay aenon to where the safety valve discharge pipe will terminate, and ensure this meets all cur-
rent building regulaons and has a connuous fall. All pipe runs for domesc hot water services (DHWS) should be
at a minimum to prevent water wastage and maximise DHWS delivery mes.
5.5 Making sure the wall the HIU is to be mounted on complies with 5.1, mark up the posion for the wall bracket. The
posion of the HIU is to be on a true vercal plane as in 5.3. Drill and plug the wall, and secure the HIU with suitable
wall xings (not provided with the HIU).

5.9 For lling the Heang Circuit for the radiators or UFH, the lling
valves and connecng pipes are integral to the HIU.
This may be removed while pipe work and isolaon valves are made
good. Ret when commissioning.
On compleon of lling the heang the temporary connecon pipe
between cold Water supply should be removed, and le for later use

5.10 Stand o brackets create a space behind the
HIU that can be used to run pipes in.
The stand o brackets are 40mm o the wall allow-
ing for 13mm pipe insulaon thickness.
First aach the brackets using 4 x xing screws to
the back of the HIU in the matching xing holes pro-
vided.
Fit the wall bracket as in 5.6 and per 5.1
Then hang the HIU as in diagram 5.6, but this me
using the outer wall bracket hooks.
Use outer bracket hooks.
5.11 Safety valve discharge pipe.
The safety valve has a 1/2” F threaded connecon for 15mm pipe to
be connected to (15mm x 1/2” M compression coupling to be provid-
ed by the installer).
The discharge pipe should have a connuous fall and conform to
BS6798.
Where the pipe empes into a drain then that area must be frost free,
and consideraon as to a trap being include as well as a tundish to
maintain any discharge is fully visible. Discharge connecon
