These instrucons describe the installaon, assembly, operaon, maintenance and fault nding of the Hiper Heat

Interface Unit (HIU). For operaon of the enre plant, the technical documentaon 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.

Installaon should only be carried out by a qualied and competent plumbing installer and a qualied and

competent electrical installer in accordance with the current Building, Water and Electrical Regulaons, Legislaon

and Standards. Do not start installaon unl you have thoroughly read and understood these Assembly and Oper-

ang Instrucons and have complied with all safety provisions.

SECTION 1 - Important informaon and introducon

Heat Interface Units (HIU) deliver heat generated from a centralised heang plant to mulple 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 heang (HTG) to the

dwelling. The Inta Hiper HIU has been developed to this concept with unique control

features to opmise its performance and operaon.

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 heang circuit (CH).

This can be by either radiators or underoor heang, the installer has the opon 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

sucient ow rate and temperature to do so.

Accessories - ‘First Fix Jig’

The installaon plan may require pipe work to be made up to the

posion 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

posion 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 isolaon valves

to be posioned. Then the Jig is removed, and the installer moves to

the next installaon and so on, unl 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

isolaon valves at a planned later date.

5.1 Before installaon read and comply with the following

Comply with all safety provisions.

The Installer’s Responsibility -in accordance with Part L of the Building Regulaons, all hot and

cold water pipes should be labelled and insulated to the current standards.

Installaon should only be carried out by a qualied and competent plumbing installer and a qualied and

competent electrical installer in accordance with the current document Building Regulaons, Legislaon

and Standards.

It is the installer’s responsibility to ensure that the place of installaon and wall is suitable.

An unsuitable locaon or provision of adequate supplies (Primary Heang and Cold Water mains) will not

jusfy any warranty or fault claim;

• The wall must be capable of bearing the weight of the HIU lled with water permanently

• Locaons where access is restricted for maintenance, see page 3.

• The HIU is only for WALL MOUNTING in the orientaon shown in this manual.

• Locaons where criminal damage or illegal tampering cannot be reasonably preventable.

• Locaons 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 Regulaons

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 posion of the HIU should be where the pipe run lengths to DHW outlets are kept to a minimum.

SECTION 5 - Installaon

05/20 E&OE

5.2 Consider which installaon 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 installaon notes

• Ensure all hot and cold water pipes are labelled and insulated in accordance with Part L of the build-

ing regulaons.

• The HIU can only be installed in one orientaon, with the heat network connecons at the top, and

in a vercal posion.

SECTION 5 - Installaon

05/20 E&OE

5.4 Ensure the chosen installaon 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 connecons will be

Required, and pay aenon to where the safety valve discharge pipe will terminate, and ensure this meets all cur-

rent building regulaons and has a connuous fall. All pipe runs for domesc 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 posion for the wall bracket. The

posion of the HIU is to be on a true vercal 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 Heang Circuit for the radiators or UFH, the lling

valves and connecng pipes are integral to the HIU.

This may be removed while pipe work and isolaon valves are made

good. Ret when commissioning.

On compleon of lling the heang the temporary connecon pipe

between cold Water supply should be removed, and le for later use

inside the HIU.

The stand o brackets are 40mm o the wall allow-

ing for 13mm pipe insulaon thickness.

First aach 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

Use outer bracket hooks.

5.11 Safety valve discharge pipe.

The safety valve has a 1/2” F threaded connecon 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 connuous fall and conform to

BS6798.

Where the pipe empes into a drain then that area must be frost free,

and consideraon as to a trap being include as well as a tundish to

maintain any discharge is fully visible. Discharge connecon
