Advice
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.
Pipe Work – the pipe runs should be
executed as short as possible, unused
pipe work should be removed and all
remaining pipe work 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.
4.1 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 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, in particular when adjusting
the temperature and timer settings.
4.2 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 pipe work
- access to water mains supply, hot
and cold water distribution pipe
work
- 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 pipe work
must be correctly insulated to avoid
frost damage.
CLEANING INSTRUCTIONS:
Clean outer cladding of
cylinder with a soft cloth
dampened with warm water
only. Do not use abrasive or
aggressive cleaning
materials, such as alcohol or
petroleum based solvents, as
this may damage the surface
of the product.
4.3 Cold Water Supply
For satisfactory and safe performance
of the unvented cylinder the water
supply must meet the following
criteria:
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 pipe work
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 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
Installation and User Instructions R02889-3 04/14
Page 10
Pre-Installation
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.
4.4 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.
4.4.1 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 18 and 27m at
least 3 sizes larger, and so on; bends
must be taken into account in
calculating the flow resistance. See
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).
Installation and User Instructions R02889-3 04/14
Page 11
Pre-Installation
Figure 2: Typical discharge pipe arrangement
Table 2: Sizing of copper discharge pipe “D2” for common temperature relief valve outlet sizes
4.4.2 Worked Example
This example is for a G½ temperature
relief valve with a discharge pipe (D2)
(as fitted on 125 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.
Installation and User Instructions R02889-3 04/14
Page 12
Pre-Installation
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 crosslinked polyethylene (PE-X)
complying with national
standards.
- be continuously marked with a
warning that no sanitary
appliances should be connected
to the pipe.
4.4.3 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.”
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.

Installation
4.5 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.
5 Installation
5.1 Cold Water Inlet with
Inlet Control Group
5.1.1 Correctly Site the
Cylinder
Install the cylinder in an appropriate
location, ensuring all of the
recommendations have been
considered (see chapter 4.2).
5.1.2 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.
Note: 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!
5.1.3 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 3: 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 4.

5.1.4 Balanced Cold Water
Supply
If a balanced cold water supply is
required a connection can be taken
from the bottom of the inlet group.
5.1.5 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.
5.2 Hot Water Outlet
The hot water pipe work is to be
directly connected to the hot water
outlet connection on the cylinder, see
Figure 1.
5.2.1 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).
5.2.2 Pipe Insulation
It is recommended to insulate the hot
water pipe work 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.
5.3 Discharge Pipes from
Safety Devices
5.3.1 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.
Installation and User Instructions R02889-3 04/14
Page 15
Installation
- 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 pipe work 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).
5.3.2 Discharge Pipe D2
For a detailed description of the
discharge pipework D2 see chapter
4.4.1.
5.3.3 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 (see Figure 2).
- 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.
5.4 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 5.5 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. A
torque of 40 Nm is recommended
when tightening up the immersion
after it has been removed and
refitted. The immersion heater
Installation and User Instructions R02889-3 04/14

Installation
thermostat must not be opened under
any circumstances.
Figure 5: Correct Operation of Immersion
Heater
Note: 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.
5.5 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.
To access the electrical connection
panel, remove the enclosure hood by
removing the 4 retaining screws on
the sides, as shown in Figure 6. 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 7.
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 8.

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 pipe
work to be insulated
- the secondary return pump to be of
suitable material and specification

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.

10 User Instructions
10.1 General
“This appliance can be used by children aged from 8
years and above and persons with reduced physical
sensory or mental capabilities or lack of experience and
knowledge if they have been given supervision or
instruction concerning use of the appliance in a safe way
and understanding the hazards involved. Children shall
not play with the appliance. Cleaning and user
maintenance shall not be made by children without
supervision.”
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.
10.2 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.
