5.6 Risk Assessment

It is strongly recommended to complete a risk assessment 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.
• 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 hereafter is the responsibility of the competent 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.

5.7 Siting Considerations

When choosing the place where the appliance is to be installed the following points should be taken into consideration:

• Structural integrity.
• Access for installation, operation, maintenance and replacement.
• Routing of discharge pipework.
• Access to water mains supply, hot and cold water distribution pipework.
• Access to suitable electricity supply.

It is PROHIBITED:

• To let the appliance operate using air intake which contains solvents or explosive matter.
• To use air intake which contains grease, dust or aerosol particles.
• To connect vented exhaust hoods to the ventilation system.

It is PROHIBITED to install the appliance

• Outdoors
• In rooms which are exposed to frost
• In humid rooms which have a lot of steam or vapour (for example, a bathroom)
• To install product directly onto floor, tripod MUST be used

The water heater may be located on any flat and level surface, provided it is sufficiently robust to support the weight of the water heater when full of water (please see technical data) and suitably accessible for replacement/maintenance without specialist tools or lift-

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

The position and orientation of the water heater 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 water heater all labels should be clearly visible and ensure that no pipework hinders any work to be carried out on the various components.

To facilitate the condensates flow, adjust the feet so that the appliance is vertical, see Figure 1.

Figure 1: Correct siting of Water Heater

Once the heat pump water heater is installed in its definitive place, it is important to wait 15 minutes before turning the appliance on

5.8 Installation

5.8.1 On-ground Installation

A tripod, makes it able to install the heat pump water heater on the ground. The height of the tripod is adjustable from 300mm to 500mm. To adjust the tripod horizontally, each foot is equipped with an adjustment screw to be used for this purpose.

Figure 2: Correct siting of Water Heater on tripod

5.9 Cold Water Supply

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

Minimum dynamic pressure 150Kpa (1.5 bar)

Maximum inlet supply pressure 1200Kpa (12 bar)

Minimum flow rate 15l/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 water heater:

• The cold water supply to the water heater 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.

Dimplex recommend an annual maintenance inspection is carried out on the water heater. 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 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 heater require de-scaling, this must be performed by a qualified technician.

Do not install the air intake nozzle near a vapour exhaust (minimum distance 0.6m).

5.10 Building Regulation G3 Discharge Requirements

As part of the requirements of Building Regulation G3 this product is factory fitted with a T&P valve, which complies with BS EN 1490. Any discharge from a water heater 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.

5.10.1 Discharge Pipe D2

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".

Dimplex strongly recommends the use of metal pipework only and Dimplex does not take responsibility 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 18m and 27m at least 3 sizes larger, and so on; bends must be taken into account in calculating the flow resistance.

See Figure 3, 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).

Figure 3: Typical discharge pipe arrangement

Value outlet size	Minimum size of discharge pipe before tundish (mm)	Minimum size of discharge pipe after tundish (mm)	Maximum allowed length of pipe after tundish (m)	Length to be subtracted for each elbow or bend (m)
G1/2 15 22 9 0.8
	28 18 1	0
	35 27 1	4
G3/4 22 28 9 1.0
	35 18 1	4
	42 27 1	7
G1 28 35 9 1.4
	42 18 1	7
	54 27 2	3

Table 2: Discharge

5.10.2 Worked Example

This example is for a G ^1/2 temperature relief valve with a discharge pipe (D2) 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 G1/2 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 G½ temperature relief valve is: 18m.

Subtract the resistance for 4 No. 28mm 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.

5.10.3 Termination of discharge pipe

- "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."

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.

6 Installation

6.1 Correctly Siting the Water Heater

Install the water heater in an appropriate location, ensuring all of the recommendations have been considered (see Section 5.6 and 5.7).

6.2 Cold Water Inlet with Inlet Group

6.2.1 Install the Inlet Group

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

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

Figure 4: Inlet Connections

6.2.2 Expansion Vessel

The expansion vessel is mandatory on the Dimplex water heater 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, see Figure 5. No isolating device should be fitted between the water heater and the cold water inlet group.

Furthermore, it is recommended to mount the vessel higher than the water heater to avoid having to drain the water heater when maintaining and replacing the expansion vessel.

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

Figure 5: Connection of the expansion vessel

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 5.

Figure 6: Cold water inlet group

NOTE: The drain valve must be installed lower than the appliance to ensure all of the water is drained away should the immersion heater need to be serviced.

6.2.3 Balanced Cold Water Supply

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

6.2.4 Drain Valve

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

6.3 Hot Water Outlet

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

6.3.1 Thermostatic Mixing Valve

Should a thermostatic mixing valve be required to limit the temperature delivered to the how water taps, a risk assessment for the prevention of Legionella must be carried out. The mixing valve must be installed according to the manufacturers 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).

6.3.2 Pipe Insulation

To comply with Part L requirements it is necessary to insulate the hot water pipework from the water heater 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.

6.4 Discharge Pipes from Safety Devices

6.4.1 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 (Dimplex part number R00836-1).

6.4.2 Discharge Pipe D2

For a detailed description of the discharge pipework D2 (see Section 5.10.1).

6.4.3 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 (see Figure 2).

Where discharge 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.

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

6.5 Immersion Heater

The Edel Air Source Heat Pump Water Heater comes with the immersion heater factory fitted and wired. The immersion heater incorporates an independent non-self resetting over temperature cut-out. Should this operate, please investigate the cause of the cut out before resetting (See Troubleshooting).

The water heater must be filled with water before applying power to the appliance or energizing the element. Failure to do so will damage the element and void any guarantee on the product.

Figure 7: Wiring diagram for Immersion Heater

6.6 Air Connection

The Edel 170 uses a concentric air ducting system (duct-induct) which supplies outside air to the appliances and discharges exhaust air outdoors. The heat pump operates over a large air temperature range (from -7°C to 35°C) using energy from outdoor air to produce domestic hot water. It is essential to correctly design and install the air ducting system to ensure the product operates properly and complies with regulations.

The air supply to and from the Edel heat pump water heater must NOT extract air from the living space of the dwelling. The air must be supplied to the appliance directly from the outside or from another source outside the thermal envelope of the living space.

The ducting used to connect the air intake and exhaust must be sufficiently insulated to prevent condensation forming. Condensation may result in damage to the appliance and/or building fabric.

Dimplex does not take any responsibility for issues caused by poor ducting design or installation.

Figure 9 provides an example of how the ducting inlet and outlet connections should be installed.

Figure 9: Examples of air connection to the water

Dimplex does not take responsibility for installation and the operating efficiency of the appliance when installed outside the scope of the guidelines provided in this document.

Failure to use the concentric ducting supplied will prevent the product working properly. Dimplex only recommend using the ducting supplied and maintaining the shortest possible duct runs.

6.7 Ducting Design

It is essential to maintain a minimum air flow rate through the ducting for correct operation of the appliance. The minimum mass flow rate must not drop below 90m3/hr

NOTE: The system reliability and efficiency will be compromised should the mass air flow rate drop below 90m^3/hr .

Actual Air Flow Rate Maxi mum Pressure Drop
90 m3/hr 90 Pa
100 m3/hr 75 Pa
110 m3/hr 50 Pa
120 m3/hr 40 Pa

During the product specification stage, it is essential that the system designer calculated the required total quantity of ducting connections, lengths, bends and terminations to establish an accurate value for total system pressure drop based on the system air flow rate requirements.

6.7.1 Worked Example

Each ducting component produces a pressure drop that changes with air flow rate. Table 3 illustrates the pressure drop for each ducting component at various system air flow rates.

Accessories Schema Pressure drop/ typical air flow

		9 Pa/m	12 Pa/m	23 Pa/m
Accessible Concentric Elbow 90°∅80/125		90m^3/h	100m^3/h	140m^3/h

Elbow 45°∅80/125		90m^3/h	100m^3/h	140m^3/h
		19 Pa	23 Pa	47 Pa

Table 3: Ducting accessories

For a typical installation, the calculation as presented in Table 3 is applicable

Accessories	Number	ΔP at nominal air flow 140m3/h
Extension insulated ø80/125	4,5	104 Pa
Accessible 90° elbow	1	65 Pa
Terminal horizontal	1	65 Pa
ΔP total		234 Pa

Accessories	Number	ΔP at nominal air flow 90 m3/h
Extension insulated ø80/125	4,5	41 Pa
Accessible 90° elbow	1	24 Pa
Terminal horizontal	1	25 Pa
ΔP total		90 Pa

NOTE: The calculated worked example includes all the necessary ducting components to complete the installation and has resulted in a total system pressure drop of 90Pa at 90m3/hr mass air flow rate. This is acceptable as the pressure drop is below the maximum permissible allowed. Only use ducting components that have available pressure drop values.

6.8 Ducting Installation

When installing the air ducting ensure the Edel is situated on the tripod provided and note the correct positions for installing the air connections as illustrated in Figure 9. Dimplex offer a basic vent kit is provided with the product to accommodate installations as per 6.8.1 and 6.8.2. Should it be necessary to install the product further away from the nearest outside wall the vent extension kit is required. The extension vent kit part number is noted on Section 8.7.

NOTE: For installations with longer air duct runs, the total pressure drop must be considered and the ducting components sourced and installed correctly by the installer.

6.10 Draining the Condensate

The condensates tube should not be directly connected to a drain. It must terminate into open air through a U-bend which has been added and contains water.

- Do not use an elbow on the flexible hose

Figure 14: Detailing the correct connection of condensate draining

6.11 Electrical Connections

The power supply should comply with the regulations in the country of installation, as well as the IEE Wiring Regulations.

A means of disconnection which ensures an electrical isolation in Category III conditions should be installed in fixed cabling in compliance with the installation rules.

Protect the appliance with :

- A 13A fused spur or isolator must be installed adjacent to the appliance for mains supply connection.

-A 16A RCBO type C circuit breaker must be fitted the local consumer unit on the same supply.

If the power supply cable is damaged it must be replaced by a suitably qualified technician or electrician.

6.11.1 Accessing Electrical Connections

To access electrical connections:

• Isolate the electrical connections.
• Remove the cover from the top of the appliance by taking out the screws which fix the lid onto the lower base of the heater.
• Remove the black protective cover from the electronic board.

Only a voltage-free, external connection may be used, or the electronics board may be destroyed.

6.11.2 Electricity Provider Contact

To stop the electrical back-up immersion running during peak time, connect the voltage-free contact from your electricity meter to terminal n°1, please refer to Figure 15.

• Contact open = electrical back-up not authorised to run
• Contact closed = electrical back-up authorised to run

If you choose load shedding level 1, the electrical back-up is prevented from running. If you choose load shedding level 0, both the electrical back-up and the heat pump will be prevented from running (see Section 7.11.6).

To prevent electrical backup operating during peak hours, if a volt free output is not available from the meter, a timer switch should be used if:

- Switch off = backup not allowed

- Switch on = backup allowed

Only a zero-voltage, external control such as a timer switch should be used (if not, the electronic board could be destroyed).

• Pass a 0.75mm 2-wire cable with crimped ends through a cable gland at the back of the appliance and bring the end of the cable round to the electronic board. The other end of the cable should be connected to the timer switch.
• Insert the 2-wire cable through a grommet on the electronics board.
• Connect the 2-wire cable to "Entrée 1" indicated on the electronic board, having removed the existing red bridge beforehand.

Figure 15: Detailing the electricity provider contact on the electronic board

6.11.3 Connecting the PV Function

This function enables the appliance to operate in auto-production mode, which means that it will use the energy produced by the PV function to supply the heat pump as well as the electrical back-up, in order to heat the water in the tank.

The connection is made between the PV Inverter and connectors 1 and 2 on the electronics board.

• Remove the appliance lid.
• Remove the black cover from the electronic board.
• Connect the PV function cable to connector 1 on the electronic board.
• If the PV function regulator has two control contacts, connect them to Entrée 1 and 2 on the electronic board (see Figure 16).
• Terminal 1: a low level of electrical energy is produced by the PV function.
• Terminal 2: a high level of electrical energy is produced by the PV function.

7 Set-Up and Operation

7.1 Commissioning

Deterioration risk: The water tank must be filled before the appliance is switched on or connected to a power supply.

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

3) Before turning on the mains supply to the water heater a hot water tap should be opened, preferably on the same floor or the floor below where the water heater 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 water heater 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 water heater.
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 water heater with legible and permanent writing.
13) Please register the appliance on our website www.dimplex.co.uk/register

Figure 16: Diagram showing PV connections

7.2 Using your Hot Water Heat Pump

The hot water heat pump mainly operates with the heat pump, as long as the air intake temperature remains in the authorised - 7°C to + 35°C range. Outside of this range, electrical backup ensures that the domestic hot water is heated.

The domestic hot water temperature provided by the heat pump is adjustable up to 60^ C. In case of high domestic hot water consumption, the domestic hot water heater has a comfort function which increases the heating capacity when there is less than 1/3 of the tank's volume left at over 38^ C (see Section 7.11.5). There is also a setting (see section 7.11.7) to activate electrical backup if the heating time is too long.

If more domestic hot water is required from time to time, the heat pump water heater has a "Boost" function (activated by the user) which ensures that the water heats to the desired temperature (for example: 50°C) quickly with the help of the heat pump and electrical backup. This function is deactivated as soon as the required temperature is reached.

From time to time, check that there are no alerts (in case of an alert, please refer to Section 8.6).

11. Re-commission unit (see chapter 7.1).

8.2 Heat Pump

Any work on the refrigerant circuit must be carried out by a qualified professional with an F Gas Category 1 certificate of aptitude.

It is strictly prohibited to release refrigerant into the atmosphere. The refrigerant must be collected before any work is carried out on the circuit.

1. Remove insulation from ducting as well as the ducting itself and thus remove the hood from the unit as per figure 18 to expose the compressor, heat exchanger etc.
2. Check the compressor for ice formation.
3. Check the circuit for leak-tightness by carrying out a test of the refrigeration components with an appropriate R290 sniffer.
4. Check whether the components of the refrigerant circuit show any signs of rust or traces of oil.
5. Check the unit's components for wear or defective items.
6. Inspect for build-up of debris in ducting and hood, remove if necessary.
7. The heat exchanger should be examined for dirt and dust and cleaned with warm water carefully to avoid damaging the fins. Make sure that the air can circulate between the fins and around the product.
8. Check that the cables are securely seated on the connection terminals.
9. Check that the fan runs freely.

Figure 18: Hood removal
