5.5 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
water outlet of the cylinder.
- Explosion: the unit is fully equipped with all relevant
safety equipment to comply with current regulations.
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.
5.6 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)
weight of the water heater 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.
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.
Figure 1: Correct siting of Water Heater
5.7 Cold Water Supply
For satisfactory and safe performance of the water
heater the water supply must meet the following
criteria:
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 quality testing. The heating elements may require
periodic de-scaling. The installer should do this as part
of a maintenance agreement.

Pre-Installation
5.8 Building Regulation G3 Discharge
Requirements
As part of the requirements of Building Regulation G3
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
Building Regulation approved document G3, (England
and Wales), Part P of Northern Ireland and Standard
4.9 of Scotland.
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
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
Figure 2, 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).
This example is for a G½ 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 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 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.
Figure 2: Typical discharge pipe arrangement
If required, precautions can be taken to minimise
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

Installation
5.8.3 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
- 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
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).
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
safety devices could be isolated!
6.2.2 Expansion Vessel
The expansion vessel is mandatory on the Dimplex
water heater and can be connected directly to the cold
with the vessel. The expansion vessel should always be
instructions, see Figure 3. No isolating device should be
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
The pre-charge should be greater than or equal to 3
bar.
Figure 3: Connection of the expansion vessel
to the inlet group
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 4.
6.2 Cold Water Inlet with Inlet Group
- 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.

If balanced cold water supply is required a connection
can be taken from the bottom of the inlet group.
6.2.3 Balanced Cold Water Supply
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.
6.2.4 Drain Valve
6.3 Hot Water Outlet
The hot water pipework is to be directly connected to
the hot water outlet connection on the water heater.
A thermostatic mixing valve may be required to limit
the outlet temperature. In this case, the valve should
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).
6.3.1 Thermostatic Mixing Valve
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.
6.4.2 Discharge Pipe D2
For a detailed description of the discharge pipework D2
(see Section 5.8.1).
6.4.3 Tundish
The tundish should be vertical, located in the same
space as the unvented hot water storage system and be
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
before switching on the immersion heater. Failure
to do so will damage the element and void any
guarantee on the product.
It is recommended 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,
and the cold water inlet pipes.
6.3.2 Pipe Insulation

6.7 Ducting Design
The heat pump operates over a large air temperature
range (from -7°C to 35°C) using energy from outdoor
air. 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 di-
rectly from the outside or from another source outside
the thermal envelop of the living space.

- 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
7.10.2.4).
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 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

Set-Up and Use
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.
6.9.1.2 Connecting the PV Function
- 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 9).
- 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.

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
There is also a setting 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 8.5).
