Any water distribution system/installation must comply with the relevant
recommendations of the current version of the Regulations and British Standards
listed below:Building Regulations
Requirements for Electrical Installations
Water Regulations
Manual Handling Operations Regulations
British Standards
BS EN 806:1-5: BS EN 8558:2011
The Building Regulations (England & Wales) require that the installation of a heating
appliance be notified to the relevant Local Authority Building Control Department.
From 1st April 2005 this can be achieved via a Competent Person Self Certification
Scheme as an option to notifying the Local Authority directly. Similar arrangements
will follow for Scotland and will apply in Northern Ireland from 1st January 06.
A suitably competent trades person must install the PulsaCoil and carry out any
subsequent maintenance/repairs. In fact the appliance front cover is secured by
2 screws and this should only be removed by a competent trades person. The
manufacturer’s notes must not be taken as overriding statutory obligations.
The PulsaCoil Stainless is not covered by section G3 of the current Building Regulations
and is therefore only notifiable to Building Control as part of the domestic water
installations.
The PulsaCoil Stainless is not intended for use by persons (including children) with
reduced physical, sensory or mental capabilities, or lack of experience or knowledge,
unless they have been given supervision or instruction concerning use of the appliance
by a person responsible for their safety.
Children should be supervised to ensure that they do not play with the appliance.
The information in this manual is provided to assist generally in the selection of
equipment. The responsibility for the selection and specification of the equipment
must however remain that of the customer and any Designers or Consultants
concerned with the design and installation.
Please Note: We do not therefore accept any responsibility for matters of design,
selection or specification or for the effectiveness of an installation containing one of
our products unless we have been specifically requested to do so.
All goods are sold subject to our Conditions of Sale, which are set out at the rear of
this manual.
In the interest of continuously improving the PulsaCoil range, Gledhill Building
Products Ltd reserve the right to modify the product without notice, and in these
circumstances this document, which is accurate at the time of printing, should be
disregarded. It will however be updated as soon as possible after the change has

The PulsaCoil Stainless shown schematically above is designed to provide an improved
method of supplying mains pressure hot water when used with a suitable off peak
electric supply/tariff.
An important feature of the concept is that hot water can be supplied directly from
the mains at conventional flow rates without the need for temperature and pressure
relief safety valves or expansion vessels. This is achieved by passing the mains water
through a plate heat exchanger. The outlet temperature of the domestic hot water
is maintained by a printed circuit control board, which controls the speed of the
pump circulating the primary water from the store through the plate heat exchanger.
Because this product does not require a safety discharge from a temperature and
pressure relief valve, any installations will be easy to incorporate into the building
and will not suffer from the problems associated with using PVCu soil stacks to take
the discharge from unvented cylinders.
The heat losses from thermal stores should not be directly compared with heat losses
from unvented or vented cylinders because they are treated differently in SAP. This
is because the unvented and vented cylinders are tested at 65°C and the thermal
store at 75°C.

The PulsaCoil Stainless units are supplied on
an installation base to allow the pipe runs to
connect to the appliance from any direction.
It is easier if all pipes protrude vertically in the
cut out area shown. Compression or push fit
connections can be used. All pipe positions
are approximate and subject to a tolerance of
+/- 10mm in any direction. Space will also be
required for a 15mm cold water supply and a
22mm warning / overflow pipe (if the optional
extra ball valve and overflow connector have
been specified. If a warning/overflow pipe
is NOT provided the F&E Cistern should be
filled from a temporary hose connection
incorporating a double check valve. This can
be from a temporary hose connection supplied
from a cold water tap or a permanent cold
branch provided adjacent to the Top up Cistern.
The temporary connection must be removed
once the appliance is filled.

Hot and Cold Water System
General
A schematic layout of the hot and cold water services in a typical small dwelling is
shown below. PulsaCoil Stainless will operate at mains pressures as low as 1 bar
and as high as 5 bar although the recommended range is 2-3 bar dynamic at the
appliance. It is also important to check that all other equipment and components in
the hot and cold water system are capable of accepting the mains pressure available
to the property. If the mains pressure can rise above 5 bar or the maximum working
pressure of any item of equipment or component to be fitted in the system, a pressure
limiting (reducing) valve set to 3 bar will be required.
If you encounter a situation where the water pressure is adequate but flow rates are
poor please contact our technical helpline for details of an effective solution.
Note : Each Pulsacoil Stainless is fitted with a strainer and flow regulator on the cold
mains supply connection. If the supply pressure is less than 2 bar or if all taps are
provided with flow regulators the flow regulator on the cold inlet should be removed.
No check valve or similar device should be fitted on the cold water supply branch to
the PulsaCoil Stainless.
The Building Regulations L1A: New dwellings/L1B: Existing dwellings and the
requirements set out in the Domestic Heating Compliance Guide specify that “where
the mains water hardness exceeds 200ppm provision should be made to treat the feed
water to water heaters and the hot water circuit of combination boilers to reduce the
rate of accumulation of lime scale”.
To comply with this requirement the hardness of the mains water should be checked
by the installer and if necessary the optional factory fitted in-line scale inhibitor should
be specified at the time of order for hardness levels between 200 and 300 ppm (mg/l).
Where the water is very hard ie 300ppm (mg/l)
and above the optional polyphosphate type,
inhibitor should be specified at the time of
order. However, this will need to be fitted by
the installer at a suitable point in the cold water
supply to the appliance.
The hot water flow rate from the PulsaCoil
Stainless is directly related to the adequacy
of the cold water supply to the dwelling.
This must be capable of providing for those
services, which could be required to be supplied
simultaneously, and this maximum demand
should be calculated using procedures defined
in BS EN 806:1-5: BS EN 8558:2011.
If a water meter is fitted in the service pipe,
it should have a nominal rating to match the
maximum hot and cold water peak demands
calculated in accordance with BS EN 806:1-5:
BS EN 8558:2011. This could be up to 60ltr/min
in some properties.
Note: The diagram below shows the top up
cistern with ballvalve and warning/overflow
pipe which can be supplied as an optional extra
if required. However, the standard preferred
arrangement is for the cistern to be manually
filled from a temporary hose connection fitted
with a double check valve.
The cistern must not be fitted more than 10
metres above the PulsaCoil Stainless appliance
itself.

Hot and Cold Water System
Pipe Sizing / Materials
To achieve even distribution of the available supply of hot and cold water, it is
important in any mains pressure system, that the piping in a dwelling should be sized
in accordance with BS EN 806:1-5: BS EN 8558:2011. This is particularly important in
a large property with more than one bathroom.
However, the following rule of thumb guide lines should be adequate for most smaller
property types as long as water pressures are within the recommended range.
1. A 15mm copper or equivalent external service may be sufficient for a small 1
bathroom dwelling (depending upon the flow rate available), but the minimum
recommended size for new dwellings is 22mm (25mm MDPE).
2. The internal cold feed from the main incoming stop tap to the PulsaCoil Stainless
should be run in 22mm pipe. The cold main and hot draw-off should also be run
in 22mm as far as the branch to the bath tap.
3. The final branches to the hand basins and sinks should be in 10mm and to the
baths and showers in 15mm (1 metre minimum).
4. We would recommend that best results for a balanced system are achieved
by fitting appropriate flow regulators to each hot and cold outlet. This is
particularly relevant where the water pressures are above the recommended
water pressure range. Details of suitable flow regulators are provided in
Appendix A.
All the recommendations with regard to pipework systems in this manual are generally
based on the use of BS/EN Standard copper pipework and fittings.
However, we are happy that plastic pipework systems can be used in place of copper
internally as long as the chosen system is recommended for use on domestic hot
and cold water systems by the manufacturer and is installed fully in accordance with
their recommendations.
This is particularly important in relation to use of push fit connections when using the
optional flexible hose kits - see installation section of this manual.
It is also essential that if an alternative pipework material/system is chosen the
manufacturer confirms that the design criteria of the new system is at least equivalent
to the use of BS/EN Standard copper pipework and fittings.
Hot and Cold Water System
If the length of the hot water draw-off pipework is excessive and the delivery time
will be more than 60 seconds before hot water is available at the tap, you may wish to
consider using trace heating to the hot water pipework such as the Raychem HWAT
system. Also a conventional pumped secondary circulation system (shown below)
can be used with any model of the PulsaCoil.

It is important that the cold water pipework is
adequately separated and protected from any
heating from the hot water pipework to ensure
that the water remains cold and of drinking
water quality.
If secondary circulation is used, there is a
possibility that excessively hot temperatures
may be experienced in the hot water supply
pipework due to the blending valve not being
able to mix with cold water because the water
is always supplied hot. A pipe thermostat is
incorporated in the circuitry which cuts the
supply to the pump when the water in the
return pipe reaches the set temperature of the
blending valve.
Secondary circulation pipework must be
insulated to prevent energy loss in both heated
and unheated areas.
Taps/Shower Fittings
Aerated taps are recommended to prevent
splashing.
Any type of shower mixing valve can be used
as long as both the hot and cold supplies
are mains fed. However all mains pressure
systems are subject to dynamic changes
particularly when other hot and cold taps/
showers are opened and closed, which will
cause changes in the water temperature at
mixed water outlets such as showers. For this
reason and because these are now no more
expensive than a manual shower we strongly
recommend the use of thermostatic showers
with this appliance.
The shower head provided must also be
suitable for mains pressure supplies.
However, if it is proposed to use a ‘whole body’
or similar shower with a number of high flow/
pressure outlets please discuss with the Gledhill
technical department.
The hot water supply to a shower-mixing valve
should be fed wherever practical directly from
the PulsaCoil Stainless or be the first drawoff point on the hot circuit. The cold supply
to a shower-mixing valve should wherever
practical be fed directly from the rising mains
via an independent branch. The shower must
incorporate or be fitted with the necessary check
valves to provide back-syphonage protection in
accordance with the Water Regulations.
The supply of hot and cold mains water directly
to a bidet is permitted provided that it is of the
over-rim flushing type and that a type ‘A’ air gap
is incorporated.

To allow the appliance to operate successfully
with on peak only supplies, two separate 16A
230V 50Hz supplies MUST be provided with
one wired into the on peak connections in the
normal way and the other wired into the off
peak connections.
In all cases the two switches/isolators must be
clearly labelled for the householders use.
INSTALLATION
The appliance is designed to be installed in an airing/cylinder cupboard and the
relevant minimum dimensions are provided in the Technical Data section of this
manual.
Because of the ease of installation we recommend that the cupboard construction is
completed and painted before installation of the appliance. The cupboard door can
be fitted after installation.
If the unit needs to be stored prior to installation it should be stored upright in a dry
environment and on a level base/floor.
Installation and maintenance access is needed to the front of the appliance and above
the Top up cistern. See the Technical Data section of this manual for further details.
The minimum dimensions contained in the Technical Data section of this manual
allow for the passage/connection of pipes to the appliance from any direction as long
as the appliance is installed on the installation base provided. If the installation base
is not used extra space may be needed to allow connection to the pipework and the
whole of the base area should be continuously supported on a material which will
not easily deteriorate if exposed to moisture.
The floor of the cupboard needs to be level and even and capable of supporting the
weight of the appliance when full. Details of the weight when full is provided in the
Technical Data section of this manual.
The appliance is designed to operate as quietly as practicable. However, some
noise (from pumps etc) is inevitable when hot water is being used. This will be most
noticeable if the cupboards are located adjacent to bedrooms, on bulkheads, or at
the mid span of a suspended floor. Some noise may also be experienced from the
immersion heaters as the store approaches its design temperature.
Cupboard temperatures will normally be slightly higher than in a conventional system
and the design of the cupboard and door will need to take this into account. No
ventilation is normally required to the cupboard.
The separate Top up cistern will need to be located on top of the appliance or at high
level in the cupboard housing the PulsaCoil Stainless. The dimensions and clearances
are provided in the Technical Data section of this manual. The location will need to
provide a suitable route for the cold feed expansion pipe as well as the open safety
vent pipe. The location will also need to provide a suitable route and discharge position
for the warning/overflow pipe and the ballvalve supply from the mains cold water
system (if provided) if these have been ordered as an optional extra.
Note: The standard appliance is supplied with a cistern without a ballvalve/
overflow for filling manually.
An electrical supply must be available which is correctly earthed, polarized and in
accordance with the latest edition of the IEE requirements for electrical Installations
BS 7671.
The electrical mains supply needs to be 230V/50Hz.
The sizes/types of electrical supplies must be as detailed in System Details section
of this manual. A means for disconnection from the supply mains having a contact
separation in all poles that provides full disconnection under over voltage category
III conditions must be incorporated in the fixed wiring in accordance with the wiring
rules. This shall be located within 1m of the appliance and only serve the appliance.
The hot and cold water ‘first fix’ pipework should be terminated 50mm above the
finished floor level in accordance with the dimensions provided in the Technical Data
section of this manual.

Preparation/placing The Appliance In
Position.
The appliance is supplied shrink wrapped on
a timber installation base with the F&E cistern
on top of the unit. Carrying handles are also
provided in the back of the casing.
The appliance should be handled carefully to
avoid damage and the recommended method
is shown above.
Note: Although the above guidance is provided
any manual handling/lifting operations will
need to comply with the requirements of the
Manual Handling Operations Regulations issued
by the H.S.E.
The appliance can be moved using a sack truck
on the rear face although care should be taken
and the route should be even.
HANDLING
When lifting the unit work with someone of similar build and height if possible.
Choose one person to call the signals.
Lift from the hips at the same time, then raise the unit to the desired level.
Move smoothly in unison.
Larger units may require a team lift.
A specific manual handling assessment is shown in Appendix C
at the rear of this manual.
In apartment buildings containing a number
of storeys we would recommend that the
appliances are moved vertically in a mechanical
lift.
If it is proposed to use a crane expert advice
should be obtained regarding the need for
slings, lifting beams etc.
Before installation the site requirements should
be checked and confirmed as acceptable.
The plastic cover and protective wrapping
should be removed from the appliance and the
installation base (provided) placed in position.
The appliance can then be lifted into position in
the cupboard on top of the base and the front
panel removed by unscrewing the 2 screws and
lifting the door up and out, ready for connection
of the pipework and electrical supplies.
The feed and expansion cistern support shall
be installed ensuring that the base is fully
supported, the working head of the appliance
is not exceeded and the recommended access
is provided for maintenance - see the Technical
Data section of this manual for details.

INSTALLATION
Feed And Open Vent Pipe
Electrical Connection - Standard Appliance
It is normally envisaged that the top up cistern will be located in the same cupboard
as the PulsaCoil Stainless appliance itself to maintain a dry roof space.
The external wiring/connections should be
carried out by a competent person to BS7671.
The arrangement of the internal wiring is shown
on page 14.
The cold feed/open vent pipework assembly (as supplied) should be used to install
the top up cistern directly on top of the appliance.
If it is necessary to locate the cistern in the roof space (or on a higher floor) the cold
feed/open vent pipework assembly (as supplied) should be used to connect to the
top up cistern and pipework site run by the installler to connect this to the appliance.
Obviously, any pipework in the roof space and the feed and expansion cistern will
need to be adequately insulated to protect against frost damage.
Combined Feed And Open Pipe Arrangements Must Not Be Used.
No valves should be fitted in the safety open vent which must be a minimum of 22mm
copper pipe or equivalent throughout its length.
The mains cold water supply to the ballvalve (if provided) shall be provided with a
suitable servicing valve.
The overflow/warning pipe (if provided) shall have a continuous fall, be fitted to
discharge clear of the building and be sited so that any overflow can be easily observed.
It shall also be installed in a size and material suitable for use with heating feed and
expansion cisterns in accordance with BS 5449 (e.g 22mm copper) and should not
have any other connections to it.
Note: If a warning/overflow pipe is NOT provided the top up cistern should be
filled from a temporary hose connection supplied from any cold water tap or
from a permanent cold branch provided adjacent to the top up cistern. The
temporary hose must be fitted with a double check valve and removed once
the appliance is filled.
The store may fill more slowly than the feed tank. It is important to check the
water level again in the cistern after commissioning.
All the terminals are suitably labelled.
Note: Do not attempt the electrical work unless
you are competent to carry it out to the above
standards.
Before commencing check that the power source
is in accordance with the Site Requirements
section of this manual and ensure that it is
isolated as shown in the System Details section.
Run the external wiring from the adjacent
isolator through the service slot provided in the
base of the appliance.
Clamp the cables in the grips provided and
ensure all cables are routed to avoid hot
surfaces.
Note: The appliance pipework should be
bonded to earth to comply with the IEE
Requirements for Electrical Installations BS
7671.
Before switching on the electrical supply check
all the factory made terminal connections to
ensure they have not become loose during
transit.

INSTALLATION
Open the incoming stop valve and fill the domestic mains cold and hot water systems
including the PulsaCoil Stainless appliance.
Check the water level in the top up cistern and if a ballvalve is fitted adjust if necessary.
Check the whole of the domestic hot and cold distribution systems for leaks. Fully
flush and if necessary chlorinate the hot and cold water system in accordance with
the recommendations in the Water Regulations and BS EN 806:1-5: BS EN 8558:2011.
Please note that the whole of the domestic hot and cold water systems including the
appliance must be adequately flushed after chlorination. Failure to do this can cause
damage to the plate heat exchanger/immersion heaters etc. If there are any doubts
regarding this or the quality of the water being used to fill the PulsaCoil appliance an
inhibitor such as Fernox MBI or Sentinel X100 should be added to the appliance when
filling in line with the manufacturers instruction for these products.
Check that the top up tank is filled up to the water level shown on the label. If it is a
manual fill model, this is most important.
If a ballvalve is provided, turn down the servicing valve once the system is finally
filled to the point where the warning/overflow pipe will cope with the discharge
arising from a ballvalve failure.
If an overflow is not provided ensure the temporary filling hose is isolated and
removed from its connection to the cold water supply.
It is essential that all systems function properly for optimum performance.
To achieve this the flow rate from each tap should be checked and a suitable number of
taps run simultaneously to check the impact of this on the flow rate at individual taps.
We recommend that flow regulators are provided for each tap/terminal fitting
to ensure that the available flow is shared evenly - See Appendix A for further
details.
Commissioning the PulsaCoil Control System
It can be checked that the boost immersion heater is drawing current by use of a
clamp meter on the live supply when boost is active or by interrogating the printed
circuit control board in accordance with the instructions in the fault finding section
of this manual.
If an off peak supply is available at the time the appliance is switched on. Its operation
can be checked with a clamp meter as described above.
If the appliance has been connected with the polarity incorrect it will not operate at all.
See the fault finding section of the manual for further details.
Run a tap and using a digital thermometer check that the temperature of the hot
water is about 52°C. This temperature is factory set and is independent of the store
temperature assuming the store is above 55°C and typical hot water flow rates of
6-15l/min are being drawn.
At the time of commissioning, complete all relevant sections of the Benchmark
Checklist located on the inside back pages of this document.
This must be completed during commissioning and left with the product to meet
the Warranty conditions offered by Gledhill.
COMMISSIONING
Page 18
Basic pump operation testing
In order to confirm that the pump is operational,
and that all air has been cleared from the pump
circuit pipe work, including the PHE. Perform the
following actions.
1. Ensure that the unit is full of water
2. Ensure that the primary pipework to the PHE
and the PHE itself are bled of air
3. Open hot water tap
4. The pump should then run and hot water
will be delivered through the tap
INSTALLATION
Circulating fluid in thermal store pipework
• The PulsaCoil Stainless and the thermal store pipework must have completed filling
prior to switching the electricity supply to the PWM controller PCB. If there is no
water in these pipes then there may be significant wear on the PWM pump.
• This can be confirmed by
- Checking the thermal store pipework servicing valves are open
- Loosening the connection points on the thermal store pipework in a systematic
manner and checking for water presence.
- Confirming that the feed and expansion tank has completed filling and the
servicing valve is open.
Cold mains water supply to plate heat exchanger and hot water taps
• Confirm that the CW mains stop valve is open
• Open all HW taps and confirm that the water runs freely and that any air is bled
from the DHW system
• Determine the maximum flow rate obtained and record
• 15l/min for all PulsaCoil products currently limited with a flow restrictor
• If flow rate not as expected determine the cause and rectify
- clean inline strainer
- check the flow restrictor is present and not blocked. It is located in the top of
the inline strainer
Power on
• Switch on the Local fuse spur and observe the PWM pump
• The green LED will flash showing the pump has a power supply and is in standby
mode.
• Open a HW tap and observe the PWM pump
• The green LED will be constantly lit showing the pump has a power supply and is
running to generate HW
NOTE: -The thermal store will only produce hot water when it is hot enough. A mid
40°C thermal store temperature will provide some hot water, higher thermal store
temperatures will provide more.
Inline scale inhibitor (if fitted)
• Check power supply
• PWM Controller PCB supplies a maximum of 12vDC/300mA to the Scale inhibition
board. (From J3)
• Check dip switches set correctly
• The correct settings for tube diameter 22mm is switch no. 3 on.
• Switch no. 4 can be either on or off.
• If the switch no. 4 is turned on the output electromagnetic field is generated
harmoniously otherwise the field is generated inharmoniously.

Important Do’s and Don’ts
Annual Servicing
1. DO check the incoming mains water pressure. The preferred range of mains
pressure is 2 -3 bar.
2. DO check the flow rate of the incoming cold water main is adequate to meet the
maximum hot and cold water simultaneous demands.
3. DO check that all connections are in accordance with the labelling on the thermal
store.
4. DO check the water level is correctly set in the top up cistern when cold and if
fitted that there is no overflow when the appliance is up to temperature.
5. DO check that the control thermostats switch the immersion heaters off at the
correct set point i.e. approx 73°C.
6. DO insulate any exposed hot water pipework in the PulsaCoil cupboard.
7. If the ballvalve in the F & E cistern is permanently connected to the mains cold
water supply DO plumb the overflow/warning pipe in a 20mm internal diameter
pipe and ensure it discharges in a conspicuous external position. Use a material
which is suitable for use with heating F & E cisterns in accordance with BS 5449
(such as copper).
8. Once the appliance is filled and commissioned DO leave the electricity switched
on to the appliance to ensure the automatic pump run facility can operate to
prevent the pump sticking.
9. DO ensure that the functioning and control of the system is explained to the
occupant.
10. DON’T place any clothing or other combustible materials against or on top of this
appliance.
No annual servicing of the PulsaCoil Stainless
is necessary.
Help and advice is also available from the
Technical Helpline on 01253 474584.
The front panel should then be refitted.
However, if required, the operation of the
controls and a hot water performance test can
be carried out to prove the appliance is working
satisfactorily and within its specification.
If it is decided to carry out the above tests the
water level in the top cistern should also be
checked and if necessary topped up.
Changing Components
Free of charge replacements for any faulty
components are available from Gledhill during
the in-warranty period on return of the faulty
part (normally 12 months).
After this, spares can be obtained direct from
Gledhill Spares or through any of the larger
plumbers merchants/specialist heating spares
suppliers.
However, all components are readily accessible
and can be changed quickly and easily by the
installer using common plumbing/electrical
practice.
Note: All maintenance work on the PulsaCoil
appliance must be carried out by a competent
trades person.
Note:
The pump is a PWM 2 pump. It has 2 cables,
one 3 core power cable and one 2 core signal
cable. These cables are part of the control
box.

Test Equipment
The initial assumption in this procedure is that the plumbing and water supply is
working effectively. If in doubt please confirm and refer to the end of this section for
advice on specific components.
A multi meter, a weir gauge and a thermometer will be required to confirm that all
the components are working effectively.
The PWM controller PCB manufacturer suggests “Fluke 87 TRUE RMS Multi meter” as
a suitable product. This will be able to measure;
- the frequency output form the Board to the pump
- the Duty cycle % output from the Board to the pump

SHOWERS
Vast quantities of water are needlessly run off to waste due to Taps, Mixers and Showers
discharging flow rates far in excess of the rates required for them to perform their
duties.
The contrasting flow rates shown on this leaflet clearly illustrate the savings that can
be made whilst still providing a good performance.
British made Aquaflow Regulators provide constant flow rates by automatically
compensating for supply pressure changes between 1 bar & 10 bars.
To facilitate installation into the wide range of plumbing equipment which is
encountered in the U.K, Four Fixing Options are available:-
2. MR05-T Range - Internal Regulators. Pushfit into Tap or Mixer seats. Produced in
three sizes - 12.5mm (BS1010), 12mm &
10mm, Flangeless models also available for
Taps with Low Lift washers.
3. MXF Standard Range - Screw on tail
models for Taps & Mixers. Fix onto the tails
before fitting the tap connectors. Available
in 3/8", 1/2", 3/4" and 1" BSP.
4. Compression Fitting Range - “In Line”
