5 Pre-Installation

Please read the following section carefully before commencing installation. If in any doubt, please call the appropriate help desk. Disregarding the instructions given in this manual in its entirety and any relevant regulations, standards and codes of practice will void the guarantee of this product.

Handling – depending on the size of the unit and access to its installation location, consideration must be given to the handling of the unit. Please note that handling, installation and use of this product is subject to the Health and Safety at Work Act. If the unit is not installed immediately, it should remain in its protective packaging with all pipe protectors/end caps applied to prevent damage and dirt deposit inside the cylinder.

Pipework – the pipe runs should be executed as short as possible, unused pipework should be removed and all remaining pipework should be lagged in accordance with regulatory requirements to prevent heat loss and the formation of condensation.

Taps and Fittings – all taps and fittings incorporated in the unvented system should have a rated operating pressure of 0.6 MPa (6 bar) or above.

5.1 Risk Assessment

The compilation of a risk assessment is strongly recommended before installing the product. The following areas require particular consideration in addition to the information required by the Health and Safety at Work Act.

Scalding - where appropriate or required by law a thermostatic mixing valve is to be fitted to the hot water outlet of the cylinder (see also water borne organisms).

Explosion - the unit is fully equipped with all relevant safety equipment to comply with current regulations. The correct design and function has been verified by independent third party testing. The correct application thereof is the responsibility of the installer.

Water Borne Organisms (i.e. Legionella) - if applicable a risk assessment should be carried out following the recommendations outlined in the Approved Code of Practice L8.

The user preference must be considered when commissioning the system, in particular when adjusting the temperature and timer settings.

5.2 Siting Considerations

When choosing a suitable location for the cylinder the following aspects should be considered:

• structural integrity
• access for installation, operation, maintenance and replacement
• routing of discharge pipework
• access to water mains supply, hot and cold water distribution pipes
• access to suitable electricity supply
• location in relation to remaining system components
• frost protection

The Quantum direct electric cylinders are designed to be floor standing, vertically mounted, indoors and in a frost free environment. The cylinder may be located on any flat and level surface, provided it is sufficiently robust to support the weight of the cylinder when full of water (please see technical data) and suitably accessible for replacement/maintenance without specialist tools or lifting equipment as this will void the warranty conditions.

The position and orientation of the cylinder should be such that easy access is provided for servicing the controls. A minimum distance of 400mm in front of the immersion is recommended, to allow the replacement of the immersion heater should the need arise. When installing the cylinder all labels should be clearly visible and ensure that no pipework hinders any work to be carried out on the various cylinder components.

Particular care must be taken when placing the cylinder in a garage or outbuilding. All exposed pipework must be correctly insulated to avoid frost damage.

5.3 Cold Water Supply

For satisfactory and safe performance of the unvented cylinder the water supply must meet the following criteria:

Minimum dynamic pressure	150 kPa (1.5 bar)
Maximum inlet supply pressure	1200 kPa (12 bar)
Minimum flow rate	15 l/min
Max. chlorine content	250mg/L
Max. water hardness	200mg/L

The following instructions have to be followed when installing the cold water mains supply to the cylinder:

• The cold water supply to the cylinder must come directly from the cold water mains after the mains stop valve to the property.
• The cold water inlet pipework should have at least an inside diameter of 19mm and should meet the requirements of the water regulations for the supply of wholesome water.

We recommend an annual maintenance inspection is carried out on the domestic hot water cylinder. In hard water areas this should include inspection of the immersion heater, [above 120ppm or 120mg/l]. A local water treatment company should be able to offer free water quality testing. The heating elements may require periodic de-scaling. The installer should do this as part of a maintenance agreement.

If required, precautions can be taken to minimise effects of water hardness, i.e. installation of a water conditioner or water softener. These devices should be installed in hard water areas where high water storage temperatures are required, i.e. greater than 60^ C storage temperatures, particularly when water hardness exceeds 200ppm. Should the water cylinder require de-scaling, this must be performed by a qualified technician.

5.4 Building Regulation G3 Discharge Requirements

As part of the requirements of Building Regulation G3 any discharge from an unvented system should be conveyed to where it is visible, but will not cause danger to persons in or about the building. The tundish and the discharge pipes should be fitted in accordance with the requirements of Building Regulation approved document G3, (England and Wales), Part P of Northern Ireland and Standard 4.9 of Scotland.

5.4.1 Discharge Pipe D2

According to the Building Regulations the discharge pipe (D2) from the Tundish should:

"have a vertical section of pipe at least 300mm long below the tundish before any elbows or bends in the pipework and be installed with a continuous fall of at least 1 in 200 thereafter."

The discharge pipe (D2) should be made of:

"metal; or other material that has been demonstrated to be capable of safely withstanding temperatures of the water discharged and is clearly and permanently marked to identify the product and performance standard".

It is strongly recommended that only metal pipe-work should be used. No responsibility will be taken for any damage caused from discharges.

The discharge pipe D2 should be at least one pipe size larger than the nominal outlet size of the safety device unless its total equivalent hydraulic resistance exceeds that of a straight pipe 9m long, i.e. for discharge pipes between 9m and 18m the equivalent resistance length should be at least two sizes larger than the nominal outlet size of the safety device; between 18 and 27m at least 3 sizes larger than the nominal outlet size of the safety device; between 18 and 27m at least 3 sizes larger, and so on; bends must be taken into account in calculating the flow resistance. See Figure 1, Table 2 and the worked example.

Note: An alternative approach for sizing discharge pipes would be to follow Annex D, section D.2 of BS 6700:2006 + A1:2009).

Table 2: Sizing of copper discharge pipe "D2" for common temperature relief valve outlet sizes

5.4.2 Worked Example

This example is for a G ^1/2 temperature relief valve with a discharge pipe (D2) (as fitted on 125l to 300l cylinders) having 4 No. 22mm elbows and length of 7m from the tundish to the point of discharge.

From Table 2, the maximum resistance allowed for a straight length of 22mm copper discharge pipe (D2) from a G½ temperature relief valve is 9.0m. Subtract the resistance for 4 No. 22mm elbows at 0.8m each = 3.2m.

Therefore the maximum permitted length equates to 5.8m, which is less than the actual length of 7m, therefore calculate the next largest size.

Maximum resistance allowed for a straight length of 28mm copper discharge pipe (D2) from a G ^1/2 temperature relief valve equates to 18m.

Subtract the resistance for 4 No. 28m.m elbows at 1.0m each = 4m.

Therefore the maximum permitted length equates to 14m.

As the actual length is 7m, a 28mm (D2) copper pipe will be satisfactory.

• Where a single common discharge pipe serves more than one system, it should be at least one pipe size larger than the largest individual discharge pipe (D2) to be connected.
• The discharge pipe should not be connected to a soil discharge stack unless the soil discharge stack is capable of safely withstanding temperatures of the water discharged, in which case, it should:

- contain a mechanical seal, which allows water into the branch pipe without allowing foul air from the drain to be ventilated through the tundish.

- there should be a separate branch pipe with no sanitary appliances connected to it.

- if plastic pipes are used as branch pipes carrying discharge from a safety device, they should be either polybutalene (PB) or cross-linked polyethylene (PE-X) complying with national standards.

- be continuously marked with a warning that no sanitary appliances should be connected to the pipe.

5.4.3 Termination of Discharge Pipe

The Building Regulations state that "The discharge pipe (D2) from the tundish should terminate in a safe place where there is no risk to persons in the vicinity of the discharge."

Examples of acceptable discharge arrangements are:

• "to a trapped gully with the end of the pipe below a fixed grating and above the water seal;
• downward discharges at low level; i.e. up to 100mm above external surfaces such as car parks, hard standings, grassed areas etc. are acceptable providing that a wire cage or similar guard is positioned to prevent contact, whilst maintaining visibility; and,

- discharges at high level: e.g. into a metal hopper and metal downpipe with the end of the discharge pipe clearly visible or onto a roof capable of withstanding high temperature discharges of water and 3m from any plastic guttering system that would collect such discharges."

Note: As the discharge would consist of high temperature water and steam, asphalt, roofing felt and non-metallic rainwater goods may be damaged by such discharges.

5.5 Limitations

Due to the operating temperatures of direct electric cylinders the water hardness can considerably influence the longevity of the immersion heater element. Please consult local water board for advice on maintenance intervals.

6 Installation

6.1 Cold Water Inlet with Inlet Group

6.1.1 Correctly Site the Cylinder

Install the cylinder in an appropriate location, ensuring all of the recommendations have been considered (see chapter 5.2).

6.1.2 Install the Inlet Group

The inlet group regulates the pressure of the incoming mains water supply to the cylinder and removes any debris that might be water borne.

Between the inlet group and the cold water inlet on the cylinder NO isolating device may be fitted, as by doing so important safety devices could be isolated!

6.1.3 Expansion Vessel

The expansion vessel is mandatory on all Quantum cylinders and can be connected directly to the cold water inlet group, utilising the flexible hose supplied with the vessel. The expansion vessel should always be fitted in accordance with the manufacturer's instructions. No isolating device must be fitted between the water cylinder and the cold water inlet group. Furthermore, it is recommended to mount the vessel higher than the cylinder to avoid having to drain the cylinder when maintaining and replacing the expansion vessel.

Figure 2: Connection of the expansion vessel to the inlet group

It is important to check the pre-charge pressure of the expansion vessel membrane before filling the cylinder. This has been factory set to 3 bar. The pre-charge should be greater than or equal to 3bar.

Note: The expansion vessel must be installed to the side of the expansion relief valve on the inlet group. To do this, the blanking plug must be removed and the expansion vessel connected, as shown in Figure 3.

Figure 3: Detail Showing the Connection of the Expansion Vessel to the Inlet Group

6.1.4 Balanced Cold Water Supply

If a balanced cold water supply is required a connection can be taken from the bottom of the inlet group.

6.1.5 Drain Valve

It is also recommended to install a drain valve (not supplied) in the lowest point of the cold water feed to the cylinder. This allows the cylinder to be drained in a controlled manner should this become necessary.

6.2 Hot Water Outlet

The hot water pipework is to be directly connected to the hot water outlet connection on the cylinder.

6.2.1 Thermostatic Mixing Valve

A thermostatic mixing valve may be required to limit the outlet temperature. In this case, the valve should be installed following the manufacturer's instructions, ensuring none of the safety equipment has been isolated, (i.e. make sure the connection to the thermostatic mixing valve is taken after the safety equipment of the inlet group).

6.2.2 Pipe Insulation

It is recommended to insulate the hot water pipework from the cylinder to the outlets, to reduce the energy requirements for providing hot water. It is also recommended to insulate all other exposed pipework, such as the T&P to the tundish, the coil flow and return and the cold water inlet pipes.

6.3 Discharge Pipes from Safety Devices 6.3.1 Discharge Pipe D1

The temperature and pressure relief valve must be discharged directly or by way of a manifold via a short length of metal pipe (D1) into a tundish; and the discharge pipe must be installed in a continuously downward direction and in a frost free environment. Water may drip from the discharge pipe of the pressure relief device and this pipe must be left open to the atmosphere.

The diameter of discharge pipe (D1) should not be less than the nominal outlet size of the safety device, e.g. temperature relief valve. Where a manifold is used it should be sized to accept and discharge the total discharge from all the D1 discharge pipes connected to it.

The discharge pipework from the expansion relief valve must be installed constantly falling to an open point of discharge. It is recommended to combine it with the discharge of the temperature and pressure relief valve.

Note: The T&P valve is pre-sealed and if moved the seal will be broken, should this occur, it will need to be resealed with an appropriate sealant (Part number R00836-1)

6.3.2 Discharge Pipe D2

For a detailed description of the discharge pipework D2 see chapter 6.3.1.

6.3.3 Tundish

The tundish should be vertical, located in the same space as the unvented hot water storage system and be fitted as close as possible to, and lower than, the safety device, with no more than 600mm of pipe between the valve outlet and the tundish.

Discharge should be visible at the tundish, where discharges may not be apparent, e.g. in dwellings occupied by people with impaired vision or mobility, consideration should be given to the installation of a suitable safety device to warn when discharge takes place, e.g. electronically operated.

Note: To comply with the Water Supply (Water Fittings) Regulations, the tundish should incorporate a suitable air gap.

It is important that the tundish is positioned away from any electrical components.

6.4 Immersion Heaters

The main immersion heater and boost immersion heater supplied with this cylinder come pre-wired. A supply cable shall be connected to the unit through the entry in the electrical enclosure, at the bottom of the cylinder. Details are given on how to do this in section 6.5 of this manual. The electrical wiring diagram for the product is shown in Figure 9.

The immersion heater incorporates an independent non self-resetting over temperature cut-out. Should the over temperature cut-out operate, the reset pin will be pushed upwards, and become level or slightly proud of the cover at the position marked "Safety", and the water in the cylinder will fail to heat. This denotes a fault somewhere in the system and an appropriate investigation shall be carried out before the cut-out is reset. Use a suitable sized implement to reset the pin by pushing it hard into its original position.

Should it be necessary to remove the thermostat from the immersion element, ensure that the contacts are re-fitted correctly into the positions on the element. Failure to do so carries the risk of overheating the contacts and thus damaging the appliance.

The immersion heater thermostat must not be opened under any circumstances.

Full tank

No water X

Never operate cylinder without water or element can burn out

Figure 4: Correct Operation of Immersion Heater

The cylinder must be filled with water before switching on the immersion heater. Failure to do so will damage the element and void any guarantee on the product.

6.5 Electrical Connection

The water cylinder has to be connected in accordance with IEE Wiring Regulations and the installer carrying out the work has to be suitably qualified. Before connecting the cylinder, verify that all the wiring connections on each of the elements and thermostats have been installed correctly, that they are secure and that none of the wires are damaged.

The electrical installation of this cylinder can be set-up for permanent supply or switched supply (peak and off-peak). For information on how to correctly wire either set-up please see Figures 7 or 8 in Section 6.5.2.

6.5.1 Access Connections

To access the electrical connection panel, remove the enclosure hood by removing the retaining screws on the sides, as shown in Figure 5. Please take care when removing the hood, as it is connected to the cylinder via an earth cable and a cable to the UI. The water cylinder requires two supply cables. Where an off-peak supply circuit is available this can be used and connected to the 'switched' supply connections marked on the terminal block. Where only one wiring circuit is available two supplies from this circuit are required. Both supplies must be connected through a separate double pole isolating switch which must have a contact separation of at least 3mm in all poles. The cables shall be connected to the unit through the entry in the electrical enclosure, at the bottom of the cylinder and should be connected to the cylinder as shown in Figure 6.

The cables should be cable-tied securely to the strain relief provided and if required cable-tied to the existing cabling on the right-hand side. The protective tape should be removed from the contact area between the hood and the cylinder cladding before commissioning as per Figure 6.

Close-up of a black cylindrical object with a red arrow pointing to a small circular feature, no visible text or symbols.

Figure 5: Retaining Screw Positions

Remove protective tape before commissioning. The two supply cables must be fed through the bottom of the enclosure. Cable ties [supplied] must be used to secure the supply cables into position along the cable clamp

Note:

The Boost connections must be connected in series with a toggle switch which allows the external boost function to be utilised.

The external boost connection on the Quantum cylinder is a contact wire which must not be connected to the mains power supply.

If an electronic timer switch from a previous installation is in place it must be replaced with a single pole toggle switch which is wired from the B1 and B2 connections as shown in Figure 7.

The water temperature required from the boost function can then be set from the UI and the boost element will automatically turn off once this temperature is achieved in 55 litres of the water stored.

When connected to a permanent supply, the charge period must be programmed on the cylinder user interface, see Section 7.

Figure 9: Wiring Schematic

6.6 Connection of Secondary Return

For cylinders that do not have a dedicated secondary return connection, it is possible to install a secondary return by connecting a swept - T to the cold water inlet of the cylinder (see Figure 10).

The secondary return pipe should incorporate a check valve and a WRAS approved circulation pump; timer and thermostat to be provided separately. Where secondary return circuits are used, then an additional expansion vessel may be required.

The secondary return loop must avoid:

• stagnant water in long pipe runs
• long waiting times at draw off point for hot water
• undue water wastage

To minimise the energy consumption of the secondary return circuit and to ensure reliable operation it is important to consider:

• the control of the circulation pump to be time and temperature controlled.
• the secondary return circuit pipework to be insulated.
• the secondary return pump to be of suitable material and specification.

7 Commissioning

At the time of commissioning, complete all relevant sections of the Benchmark Checklist located on the inside back pages of this document.

The following commissioning procedures only detail the required steps to be taken for the potable water loop:

1) Before making any mains connections to the inlet control group, flush the mains pipework out to ensure all debris has been removed so as not to damage the strainer within the combination valve.

2) Make final mains connection on combination valve and check all connections and joints to ensure they have been tightened and secured correctly.

3) Before turning on the mains supply to the cylinder a hot water tap should be opened, preferably on the same floor or the floor below where the cylinder is located.

4) Check the pre-charge in the expansion vessel and ensure it is at least 3 bar. Note actual pressure on label on expansion vessel.

5) Turn on the supply to the cylinder and fill until water runs from the open hot water tap. Continue to flush the system until all debris has been removed.

6) Close the hot water tap.

7) Check all joints for leaks, even those not having been altered especially when replacing a vented cylinder.

8) Open temperature and pressure relief valve to ensure proper discharge and check after closing that valve is not dripping.

9) Open expansion relief valve to ensure proper discharge and check after closing that valve is not dripping.

10) Check all shower outlets, toilet cisterns and other draw off points for leaks or dripping (especially when replacing a vented unit). Open all water outlets to purge air from pipework and ensure proper operation.

11) Instruct user in the operation of the unit and hand over this manual advising the owner of annual service requirements.

12) Complete the technical data label on the cylinder with legible and permanent writing.

11 User Instructions

11.1 General

Please read the following statements carefully as it affects your warranty.

Please ensure that the installer has fully completed the Benchmark Checklist on the inside back pages of this document and that you have signed it to say that you have received a full and clear explanation of its operation. The installer is legally required to complete a commissioning checklist as a means of complying with the appropriate Building Regulations Part G3 (England and Wales), Part P of Northern Ireland and Section 6 of Scotland.

All installations must be notified to Local Area Building Control either directly or through a Competent Persons Scheme. A Building Regulations Compliance Certificate will then be issued to the customer who should, on receipt, write the Notification Number on the Benchmark Checklist.

This product should be serviced annually to optimise its safety, efficiency and performance. The service engineer should complete the relevant Service Record on the Benchmark Checklist after each service.

The Benchmark Checklist will be required in the event of any warranty work.

The permanent supply to the cylinder must be maintained at all times. The cylinder will ensure that heating only occurs during off-peak periods. If hot water is not required for a number of days Holiday mode should be activated. Failure to maintain the permanent supply can lead to cylinder malfunction.

11.2 Operation

The hot water temperature can be set to various requirements. It is recommended to set the hot water temperature to between 45^ C and 55^ C. Higher temperatures can introduce more heat loss from the unit and increase the risk of scalding significantly. A thermostatic mixing valve should be considered.

When turning on a hot tap for the first time after a heat up period there might be a short surge of water. This is normal in unvented systems and does not constitute a fault. Sometimes the water may appear milky – this is due to very fine air bubbles in the water which will clear quickly.

11.2.1 User Interface

The user interface consists of the following components as shown in Figure 15.

Quantum 1 25°C 3 4 5

Access to the main menu is by pressing the menu button on the User interface (labelled 2 in Figure 15).

The following parameters can then be set and changed by the user:

• setting of date and time, primary and boost immersion heater set temperature (see Figure 17)
• setting of functions (see Figure 20)
• display settings (see Figure 18)

11.2.2 Home Screen

The Home screen displays live information on the current status of the hot water cylinder.

1. Current outlet water temperature
2. Charge status of the cylinder section. E.g. shaded when the temperature is greater than or equal to 40^ C.
3. Software version on the Charge Controller and User Interface.

The colour of the display will turn red once 48 °C is exceeded.

Above this temperature is generally considered to be unsafe and could cause a serious scald. The user should always run the cold tap first when filling a bath and test the water before getting into a bath or shower. The recommended temperature for bathing is 37^ C.
