Pre-Installation
5.2 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 pipes
- access to suitable electricity supply
- location in relation to remaining system
components
- frost protection
The Quantum direct electric cylinders are
designedtobeoorstanding,verticallymounted,
indoors and in a frost free environment. The
cylindermaybelocatedonanyatandlevel
surface,provideditissufcientlyrobustto
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.
5.3 Cold Water Supply
For satisfactory and safe performance of the
unvented cylinder the water supply must meet the
following criteria:
Minimum dynamic
pressure
150 kPa (1.5 bar)
Maximum inlet
supply pressure
1200 kPa (12 bar)
Minimumowrate 15 l/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
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.
We recommend an annual maintenance inspection
is carried out on the domestic hot water cylinder.
In hard water areas this should include inspec-
tion 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 devic-
es should be installed in hard water areas where
high water storage temperatures are required, i.e.
greater than 60°C storage temperatures, par-
ticularly when water hardness exceeds 200ppm.
Should the water cylinder require de-scaling, this
mustbeperformedbyaqualiedtechnician.
5.4 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
shouldbettedinaccordancewiththe
requirements of Building Regulation approved
document G3, (England and Wales), Part P of
Northern Ireland and Standard 4.9 of Scotland.
5.4.1 Discharge Pipe D2
According to the Building Regulations 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”.
7
We strongly recommends the use of metal pipe-
work only and GDC Group Ltd 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 than the nominal outlet
size of the safety device; between 18 and 27m at
least 3 sizes larger, and so on; bends must be
takenintoaccountincalculatingtheow
resistance. See Figure 1, 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).

Table 2: Sizing of copper discharge pipe “D2”
for common temperature relief valve outlet sizes
Pre-Installation
This example is for a G½ temperature relief valve
withadischargepipe(D2)(asttedon125Lto
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.
Maximum resistance allowed for a straight length
of 28mm copper discharge pipe (D2) from a G½
temperature relief valve equates to 18m.
Subtract the resistance for 4 No. 28m.m 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.
Notes:
1.) 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.
2.) 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.
5.4.2 Worked Example
8
Installation
The Building Regulations state that “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
belowaxedgratingandabovethewaterseal;
- 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,
roongfeltandnon-metallicrainwatergoods
may be damaged by such discharges.
5.4.3 Termination of Discharge Pipe
5.5 Limitations
Due to the operating temperatures of direct
electric cylinders the water hardness can
considerablyinuencethelongevityofthe
immersion heater element. Please consult local
water board for advice on maintenance intervals.

6 Installation
Install the cylinder in an appropriate location,
ensuring all of the recommendations have been
considered (see chapter 5.2).
6.1 Cold Water Inlet with Inlet Group
6.1.1 Correctly Site the Cylinder
The inlet group regulates the pressure of the
incoming mains water supply to the cylinder and
removes any debris that might be water borne.
Between the inlet group and the cold
water inlet on the cylinder NO isolating
devicemaybetted,asbydoingso
important safety devices could be isolated!
6.1.2 Install the Inlet Group
The expansion vessel is mandatory on all
Quantum cylinders and can be connected directly
tothecoldwaterinletgroup,utilisingtheexible
hose supplied with the vessel. The expansion
vesselshouldalwaysbettedinaccordancewith
the manufacturer’s instructions. No isolating
devicemustbettedbetweenthewatercylinder
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.
6.1.3 Expansion Vessel
Figure 2: Connection of the expansion vessel
to the inlet group
It is important to check the pre-charge pressure
oftheexpansionvesselmembranebeforelling
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 3.

inlet group.
6.1.4 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 cylinder. This allows the cylinder to be
drained in a controlled manner should this become
necessary.
6.1.5 Drain Valve
6.2 Hot Water Outlet
The hot water pipe work is to be directly
connected to the hot water outlet connection on
the cylinder.
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).
6.2.1 Thermostatic Mixing Valve
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,
thecoilowandreturnandthecoldwaterinlet
pipes.
6.2.2 Pipe Insulation
6.3 Discharge Pipes from Safety Devices
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 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 (see Figure 13)
6.3.1 Discharge Pipe D1
The tundish should be vertical, located in the
same space as the unvented hot water storage
systemandbettedascloseaspossibleto,and
lower than, the safety device, with no more than
600mm of pipe between the valve outlet and the
tundish.
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.
6.3.3 Tundish
For a detailed description of the discharge pipe-
work D2 see chapter 6.3.1.
6.3.2 Discharge Pipe D2
It is important that the tundish is positioned away
from any electrical components.
10
Installation
6.4 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 6.5 of this manual. The
electrical wiring diagram for the product is shown
in Figure 8.
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-ttedcorrectlyintothepositionson
the element. Failure to do so carries
the risk of overheating the contacts
and thus damaging the appliance.
The immersion heater thermostat must not be
opened under any circumstances.
Figure 4: Correct Operation of Immersion Heater
Thecylindermustbelledwith
water before switching on the
immersion heater. Failure to do so
will damage the element and void any
guarantee on the product.
6.5.1 Access Connections
To access the electrical connection panel, remove
the enclosure hood by removing the retaining
screws on the sides, as shown in Figure 5. 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 6.
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 6.
Figure 5: Retaining Screw Positions
6.5 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
qualied.Beforeconnectingthecylinder,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.
The electrical installation of this cylinder can be
set-up for permanent supply or switched supply
(peak and off-peak). For information on how to
correctly wire either set-up please see Figures 7
or 8 in Section 6.5.2.
Remove protective tape before
commossioning.
The two supply cables must be
fed through the bottom of the
enclosure.
Cable ties [supplied] must be
used to secure the supply
cables into position along the
cable clamp

Note:
The Boost connections must be connected in series with a toggle switch which allows the external boost function to be utilised.
The external boost connection on the Quantum cylinder is a contact wire which must not be connected to the mains power supply.
If an electronic timer switch from a previous installation is in place it must be replaced with a single pole toggle switch which is
wired from the B1 and B2 connections as shown in Figure 7.
The water temperature required from the boost function can then be set from the UI and the boost element will automatically turn
off once this temperature is achieved in 55 litres of the water stored.
When connected to a permanent supply, the charge period must be programmed on the cylinder user interface, see Section 7.

Commissioning
6.6 Connection of Secondary Return
For cylinders that do not have a dedicated
secondary return connection, it is possible to
install a secondary return by connecting a swept -
T to the cold water inlet of the cylinder (see Figure
10).
The secondary return pipe should incorporate
a check valve and a WRAS approved circula-
tion 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 sec-
ondary return circuit and to ensure reliable opera-
tion it is important to consider:
- the control of the circulation pump to be time
and temperature controlled

11.1 General
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
signicantly.Athermostaticmixingvalveshould
be considered.
Whenturningonahottapforthersttimeafter
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
