The following instructions have to be followed when install-
ing 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
-
ing elements may require periodic de-scaling. The installer
should do this as part of a maintenance agreement.

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 re-
quired, i.e. greater than 60°C storage temperatures, par-
ticularly when water hardness exceeds 200ppm. Should the
water heater require de-scaling, this must be performed by
5.10 Building Regulation G3 Discharge
Requirements
As part of the requirements of Building Regulation G3 this
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
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
Dimplex strongly recommends the use of metal pipework
only and Dimplex does not take responsibility for any dam-
age caused from discharges.
The discharge pipe D2 should be at least one pipe size larg-
er 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
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 2: Correct siting of Water Heater on tripod
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”
Figure 3: Typical discharge pipe arrangement
!
The heat pump water heater must be an-
chored to the wall to avoid any danger of
tipping or falling.
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.

Pre-Installation
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 tem-
perature 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 calcu-
late 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.
5.10.2 Worked Example
5.10.3 Termination of discharge pipe
- 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.

Installation
6 Installation
6.1 Correctly Siting the Water Heater
Install the water heater in an appropriate location, en-
suring all of the recommendations have been considered
(see Section 5.6 and 5.7).
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 water

-
ance with the manufacturer’s instructions, see Figure 5. No
and the cold water inlet group.
Furthermore, it is recommended to mount the vessel high-
er 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
pre-charge should be greater than or equal to 3 bar.

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.
6.3 Hot Water Outlet
The hot water pipework is to be directly connected to
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 accord-
ing 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).
6.3.1 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.
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
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 applying power to the appliance or
energizing the element. Failure to do so will
damage the element and void any guaran-
tee on the product.
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 insu-
late all other exposed pipework, such as the T&P to the
6.3.2 Pipe Insulation
The Edel Air Source Heat Pump Water Heater comes
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).
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).

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

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 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.
6.11.3 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 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.

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 do-
mestic hot water consumption, the domestic hot water
heater has a comfort function which increases the heat-
ing 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).
