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.
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 out-
let size of the safety device; between 18m and 27m at
least 3 sizes larger, and so on; bends must be taken into
Figure 2, Table 2 and the worked example.
If required, precautions can be taken to minimise
-
ditioner or water softener. These devices should be in-
stalled 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 re-
quire de-scaling, this must be performed by a

Dimplex recommend an annual maintenance
inspection is carried out on the water heater. In hard wa-
ter 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.
- 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.
Note: An alternative approach for sizing discharge pipes
would be to follow Annex D, section D.2 of BS 6700:2006
+ A1:2009).
- The cold water supply to the water heater must come
directly from the cold water mains after the mains
stop valve to the property.
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.
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 following instructions have to be followed when
installing the cold water mains supply to the water
heater:
Minimum dynamic pressure 150Kpa (1.5 bar)
Maximum inlet supply pressure 1200Kpa (12 bar)
Minimum ow rate 15l/min
Max. chlorine content 250mg/L
Max. water hardness 200mg/L
For satisfactory and safe performance of the water
heater the water supply must meet the following
criteria:
5.7 Cold Water Supply
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
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 re-
sistance for 4 No. 22mm elbows at 0.8m each = 3.2m.

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.”
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.
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.
5.9 Product Disposal
This product has been manufactured from
mostly recyclable materials. At the end of the
product’s life, it should be disposed of at a Local
Authority Recycling Centre.
Materials:
• Inner Cylinder - Stainless Steel
• Outer Cladding - HIPS/ABS (Polypropylene BE 50)
• Inlet/Outlet Pipe - Plastic (Polypropylene BE 50)
• Insulation - 50mm PU Foam (GWP =1, ODP =0)
Connections & Fasteners:
• Inlet/Oulet - stainless steel
• T&P Valve - ½”F BSP
• Immersion Heater - 1 ¼”F BSP
!
!
Safety & Control:
• Cold water inlet group - brass
• Tundish - acetal co-polymer
• T&P Valve - brass
- 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.
As the discharge would consist of high
felt and non-metallic rainwater goods may be
damaged by such discharges.
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.

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
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).
6.3.1 Thermostatic Mixing Valve
6.4 Discharge Pipes from Safety
Devices
6.4.1 Discharge Pipe D1
The temperature and pressure relief valve must be dis-
charged 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 down-
ward 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. tem-
perature 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 close as possible to, and lower than, the safety device,
with no more than 600mm of pipe between the valve out-
let and the tundish (see Figure 2).
Where discharge may not be apparent, e.g. in dwellings
occupied by people with impaired vision or mobility, con-
sideration should be given to the installation of a suita-
ble 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
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
The Edel Air Source Heat Pump Water Heater comes with
-
sion 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).

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 dis-
charge 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 re-
sealed with an appropriate sealant (Dimplex part number
R00836-1).
Installation
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.

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.

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
tank’s volume left at over 38°C (see Section 7.10.2.3).
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).

Any work on the refrigerant circuit
must be carried out by a qualied
professional with an F Gas Category 1
certicate of aptitude.
It is strictly prohibited to release refrig-
erant into the atmosphere. The refriger-
ant must be collected before any work is
carried out on the circuit.
1. Remove insulation from ducting as well as the duct-
ing itself and thus remove the hood from the unit 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 ap-
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

8.3 Air intake & Exhaust
1. Both the exhaust and air intake vents must be
inspected and cleared of any debris stuck in the
vents.
2. Ensure the evaporator is checked at least once a
year, more depending on the cleanliness of the air
8.4 Heat Pump Condensation
1. To check that condensation is draining correctly:
- Remove upper cover (see Section 6.9.1).
- Check for blockages in the drainage hole.
- Clean the condensate recovery container, were de-
posits from air intake may have gathered.
2. The pressure limiting device must be switched
on regularly to eliminate limescale and check for
blockages.
3. Check that all hydraulic connections on the heat
pump water heater are watertight.
4. The condensate drain should be inspected to en-
sure the red plug has been removed and unre-
stricted draining of condensation is allowed.

conductors, taken care to not damage the strands
of the conductor wire, which would reduce the
cross-sectional area of the conductor.
4. Ensured the conductors are tightly and securely
connected to the controls or immersion heater
5. Ensured the bared conductors are correctly insert-
ed into the terminals, to avoid bearing on the insu-
lation sleeving or only partially clamping the con-
ductors.
6. Securely anchored the supply cable using the
means provided to avoid exerting any external
strain to the cable and hence to the terminals.
7. Checked to ensure the product is earthed correctly;
the Live and Neutral connections are to the correct
terminals, and the Residual Current Device (RCD)
