Terms & Conditions
Building Regulations and Benchmark Commissioning
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.
CORGI operates a Self Certification Scheme for gas heating appliances.
These arrangements represent a change from the situation whereby compliance with
the Building Regulations was accepted if the Benchmark Logbook was completed and
this was then left on site with the customer).
With the introduction of a self certification scheme, the Benchmark Logbook is being
replaced by a similar document in the form of a commissioning check list and a service
interval record is included with all gas appliance manuals. However, the relevant
Benchmark Logbook is still being included with all Thermal Storage products and
unvented cylinders.
Gledhill fully supports the Benchmark aims to improve the standards of installation
and commissioning of central heating systems in the UK and to encourage the regular
servicing of all central heating systems to ensure safety and efficiency.
Building Regulations require that the heating installation should comply with the
manufacturer’s instructions. It is therefore important that the commissioning check
list is completed by the competent installer. This check list only applies to installations
in dwellings or some related structures.
Page The Gledhill PulsaCoil range is a WBS
listed product and complies with the
WMA Specification for hot water only
thermal storage products. The principle was
developed in conjunction with British Gas.
This product is manufactured under an ISO
9001:2000 Quality System audited by BSI.
The Gledhill Group’s first priority is to give a
high quality service to our customers.
Quality is built into every Gledhill product
and we hope you get satisfactory service
from Gledhill.
If not please let us know.
DESIGN
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
BS6700 and BS7671.
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 A-Class ECO 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 A-Class 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.

The PulsaCoil A-Class ECO shown schematically above is a very highly insulated version
of the standard PulsaCoil A-Class appliance. As such, the products will allow a pass to
be achieved in SAP2005 even in small apartment situations. However, the product
still retains the basic principles of the standard PulsaCoil A-Class product which is to
provide an improved method of supplying mains pressure hot water when using a
suitable off peak electric supply/tariff.
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. The
SAP calculator takes account of the type of store and various correction factors are
included to reflect the different ways that the hot water and heating operates.

The main 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.
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
Page 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,
scale 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 printed circuit board incorporates the
facility to automatically run the D.H.W.
primary pump for about 3 seconds every
30 hours to help prevent it sticking. For
this reason we would recommend that
once the appliance is installed it should be
commissioned and the on peak electricity
supply left on to the appliance.
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.

TECHNICAL DATA
1. 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. The SAP calculator takes account of the type of store and various correction
factors are included to reflect the different ways that the hot water and heating
operates.
2. The flow rates are based on a 35°C temperature rise and assume that recommended
pressures and adequate flow are available at the appliance. The flow rate will be
reduced if the available water pressure is below that recommended. The actual
flow rate from the appliance is automatically regulated to a maximum of 27 litres/
min.
3. The domestic hot water outlet temperature is automatically regulated to
approximately 52°C at the bath flow rate of 18 litres/min recommended by BS
6700. The temperature is not user adjustable.

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 A-Class ECO 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.
If the manifolds (available as an optional extra) are being used the inlet pressure to
the manifold must be a minimum of 2 bar. 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 A-Class ECO 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 the manifolds
(available as an optional extra) are being used 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 A-Class ECO.
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 AClass ECO 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 6700.
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 6700. This
could be up to 60ltr/min in some properties.
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”.
Note: The diagram below shows the Top up
cistern with ballvalve and warning/overflow
pipe. The ballvalve/overflow connector 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.
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).
The cistern must not be fitted more than
6 metres above the PulsaCoil A-Class ECO
appliance itself.

DESIGN
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 6700. 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 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.
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.
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. Please consult Gledhill
Technical Department for further details.
Note: If manifolds (available as an optional extra) are being used suitable flow
regulators are automatically provided in the manifold and do not need to be
provided at each outlet. See Appendix B for further details.
Note: A conventional pumped secondary
circulation system is NOT suitable for use with
this appliance.
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.
It is important that the cold water pipework
is adequately separated/protected from any
heating/hot water pipework to ensure that
the water remains cold and of drinking water
quality.
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.
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.
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.
SYSTEM DETAILS
The hot water supply to a shower-mixing valve
should be fed wherever practical directly from
the PulsaCoil A-Class ECO 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 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.

pressed the on-peak boost will remain active
until the next time the off-peak becomes
available (unless switched off again manually).
The size of the appliance and the need to use
the on peak boost facility is reduced if a better
off peak tariff can be agreed with the electrical
supply company - see Model Selection Guide

and the whole dwelling goes off-peak or onpeak when the tariff changes at the meter. In
this case a single channel clock will need to be
fitted in the off peak supply to the PulsaCoil AClass ECO. The off-peak time clock will need to
be synchronised with the tariff times set on the
meter and be rated for at least 3kW at 230V.

Although the PulsaCoil A-Class ECO appliance is
primarily designed to operate with an off peak
supply it will also operate quite successfully
if it is only supplied with an on peak supply.
However, this will substantially increase the

only be considered if an off peak supply is not
available.

Page 12
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, 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 A-Class ECO. The dimensions and
clearances are provided in the Technical Data section of this manual. If the top up
cistern is sited remotely, the location will need to provide a suitable route for the cold
feed expansion pipe as well as the open safety vent pipe. If the ballvalve/overflow
connector have been ordered (available as optional extras), 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.
Note: The standard appliance is supplied with a cistern without a ballvalve/
overflow for filling manually.
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.

INSTALLATION
Preparation/placing the appliance in
position.
The ‘first fix’ pipework positions should be
checked using the template provided with
each appliance. If these have been followed
installation is very simple and much quicker
than any other system.
The appliance is supplied shrink wrapped on a
timber installation base. Carrying handles are
also provided in the back of the casing.
The feed and expansion cistern complete with
ballvalve, cold feed/expansion and overflow/
warning pipe fittings are provided in a separate
box.
The appliance should be handled carefully to
avoid damage and the recommended method
is shown above.
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 D
at the rear of this manual.
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. - further details are provided
in Appendix D.
The appliance can be moved using a sack truck
on the rear face although care should be taken
and the route should be even.
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.
INSTALLATION
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
It is normally envisaged that the top up cistern will be located in the same cupboard
as the PulsaCoil A-Class ECO appliance itself to maintain a dry roof space.
Electrical Connection - Standard Appliance
If it is necessary to locate the cistern in any other location, the cold feed/open vent
pipework (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.
The PulsaCoil A-Class ECO is pre-wired internally,
strictly in accordance with the IEE Requirements
for Electrical Installations BS 7671. The external
wiring/connections should be carried out by a
competent person to the same standard. The
arrangement of the internal wiring is shown on
the previous page.
Obviously, any pipework in the roof space and the feed and expansion cistern will
need to be adequately insulated to protect against frost damage.
Details of the incoming power supplies are
shown below.
Combined feed and open pipe arrangements must not be used.
All the terminals are suitably labelled.
No valves should be fitted in the safety open vent which must be a minimum of 22mm
copper pipe or equivalent throughout its length.
Note: Do not attempt the electrical work unless
you are competent to carry it out to the above
standards.
The cold feed/open vent pipework (as supplied) should be used to install the top up
cistern directly on top of the appliance.
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 and top up if necessary.
Before commencing check that the power source
is in accordance with the Site Requirements
section of this manual and ensure that it is
isolated.
Run the external wiring from the adjacent
isolator through the service slot provided in the
base of the appliance.
Because of the exposed nature of the electrical
connections to the relays, a metal panel is fitted
over part of the electric panel. This will need to
be removed to make the connections, but MUST
be replaced prior to the electrical supply being
switched on and left in position.
Make the connections as shown below.

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 A-Class ECO appliance.
Check the water level in the top up cistern and if a ballvalve is fitted adjust if
necessary.
Put the on/off switch on the front control panel
to the on position to activate the appliance
control board. The switch will glow green when
in the on position.
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 6700.
If an off peak supply is not available the onpeak boost immersion heater will need to be
switched on by pressing the black button. The
red light will change to permanently on.
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 A-Class ECO
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.
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.
It is most important to check that the top up tank is filled up to the water level shown
on the label, if it is a manual fill model. If the optional level gauge has been provided,
the level will be shown by the red float.
The sensor control set points are shown on
page 25 and can be checked on the 2 digit
ACB display.
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.
The boost immersion heater can be switched
off by pressing again the black button.
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.
If an off peak supply is available at the time
the appliance is switched on the appliance will
automatically switch on the off peak immersion
heater. Its operation can be checked in the
same way as described above for the on peak
immersion heater. When the off peak supply
is available the on peak immersion heater
operation can still be checked as described
above by switching off the off peak supply.

Commissioning the PulsaCoil A-Class ECO Control System
Once the PulsaCoil A-Class ECO is filled with water, check the on/off switch on the
front is in the off position. The electrical supplies can then be switched on and the
switches on the two isolating terminal connectors can be pushed home.
WARNING - Pushing home these switches will complete the electrical circuit to the
immersion heaters. DO NOT PUSH HOME THESE SWITCHES AND SWITCH ON THE
ELECTRICITY SUPPLY UNTIL YOU HAVE CHECKED THAT THERE IS WATER IN THE F
& E CISTERN. Failure to do this can result in dry firing and premature failure of the
immersion heaters, which will invalidate the warranty.
Page 19
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 6-25l/min are being
drawn.
This product is covered by the ‘Benchmark’
scheme and a separate commissioning/
service log book is included with this
product. This must be completed during
commissioning and left with the product
to meet the Warranty conditions offered
by Gledhill.
COMMISSIONING
See the Fault Finding section of the manual for
further details.
SERVICING
Important Do’s and Don’ts
Annual Service
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 NOT push home the 2 switches on the isolating terminal connectors and
switch on the electricity supply until you have checked that the appliance is full
of water i.e. there is water in the top up cistern.
5. DO check the water level is correctly set in the top up cistern when cold and (if
fitted) that there is no discharge from the overflow when the appliance is up to
temperature.
6. DO check that the sensors switch the immersion heaters off at the correct set
point i.e. approx 70°C.
7. DO insulate any exposed hot water pipework in the PulsaCoil A-Class ECO
cupboard.
8. 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).
9. DO ensure the green light ‘on/off’ switch glows.
10. 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.
11. DO ensure that the functioning and control of the system is explained to the
occupant.
12.DON’T place any clothing or other combustible materials against or on top of this
appliance.
No annual servicing of the PulsaCoil A-Class
ECO is necessary.
These instructions should be placed along with the component manufacturers
instructions in the pocket provided on the top of the appliance. The appliance
should be left with the front panel fitted and screwed in position.
ANNUAL SERVICE/CHANGING COMPONENTS
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 using the ‘Speed Spares’ service, or
through any of the larger plumbers merchants/
specialist heating spares suppliers.
Help and advice is also available from the
Technical Helpline on 08449 310000.
However, all components are readily accessible
and can be changed quickly and easily by the
installer using common plumbing/electrical
practice.
However all maintenance work on the PulsaCoil
A-Class ECO appliance must be carried out by a
competent trades person.
Note: The pump is a Grundfos UPR 15-50
4 wire pattern and any replacement must
be the same model obtained from Gledhill.
Failure to do this will affect the hot water
performance.

SHORT PARTS LIST
Description
SERVICING
The PulsaCoil A-Class ECO appliance control panel and printed circuit control board/
display have been designed to be fully automatic whilst able to provide functional
and diagnostic information to the householder/installer.
The panel/board work in conjunction with a number of sensors (thermistors) located
as shown in the diagram below.
S1/S2
Automatic Control Operation
S6
Heating of the store is controlled by sensors S1/S2 and S5 and S6. The control set
points are shown in the table on page 25.
On peak IH
During normal charging cycle sensor S5 will control the bottom off peak I.H. in the
same way S6 will control the top on peak I.H. when manually activated.
S4
In the event of either of these sensors failing, control will be taken over by sensors
S1/S2.
S5
Normally, sensors S1/S2 are used to detect an overheat condition (over 95°C) which
will cause the red LED on the front control panel to flash (rapid).
This condition should not normally be reached as sensors S1/S2 will also switch off
the supplies to the I.H’s if a temperature above 85°C is detected. Normal operation will
automatically resume when the temperature at the sensors drops below 78°C.
The hot water temperature is controlled by sensors S3 and S4.
S3 checks for a drop in temperature every second and if the drop is more than 2°C,
it switches on the hot water pump to raise the domestic hot water temperature to
52°C (± 2°C).
The control of the hot water temperature is carried out by sensor S4 adjusting the
speed of the hot water pump.

2 DIGIT ACB BOARD DISPLAY FLOW CHART
Appliance Control Board
APPLIANCE CONTROL BOARD (A.C.B)
and setting the appliance code on the controller
is described below.
The appliance control board (shown above) has a 2 digit display and 2 push buttons
which are used to check the status of the appliance, check and set its identity and
interrogate it for the current faults and the fault history.
The 2 digit display is controlled by 2 buttons S1 and S2. The flow chart of display modes
is shown above. Generally, each press of button S2 cycles the display from top to bottom
and each press of button S1 cycles the display functions from left to right.
The button S2 is also used to reset the appliance i.e. clear the lockout errors and reset
the appliance.
Note: The board is used on a range of products and not all terminals are used on
every appliance.
Display in Normal (Standby) Mode
In the standard/normal mode the 2 digit display indicates the status of the appliance
inputs and outputs by switching on the appropriate segments of the display - see
page 25 for details.
Appliance Type Selection
The PulsaCoil A-Class ECO is fitted with an identity (ID) resistor which is read by the
controller for comparison with the appliance type (code) set on the controller. The two
must match for the controller/appliance to function. Therefore if either the appliance
code setting or the ID resistor is wrong, the appliance will shut down safely and flag
the error code until the fault is rectified. The controller codes and the ID resistor values
for the PulsaCoil A-Class ECO are 03 and 3K3 respectively. The procedure for checking
Page 23
• The appliance selection menu (A0 ... A9) on
the controller is hidden. It is only possible
to get to the appliance selection using the
reset button (Left hand, S2) on the main
board.
• When going from the show ‘ locking error’ to
show ‘blocking error’ menu (see opposite),
do not release the button but hold it for 10
seconds. The display will change from ‘c’ to
‘A’. At this stage the push button (S2) can be
released.
• The appliance type can now be selected by
using right hand push button, S1, e.g. for this
appliance A01.
Press the reset button, S2, to accept the
setting.
If the selected appliance code does not match
with the ID resistor fitted to the appliance, then,
an error ‘33’ will be displayed.

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 &

APPENDIX
The pressure loss through a flow regulator at the
designated flow rate is about 1.8 bar. Therefore
for the flow regulator to control the flow rate at
pre-set level, the inlet pressure must be greater
than 1.8 bar. If the inlet pressure is lower, the
flow rate will be correspondingly less than the
pre-set values.
The maximum equivalent pipe lengths from
the manifold to the terminal fittings can be
estimated from the above information and
the resistance characteristics of the pipes.
The examples presented below are for 15mm
copper pipe in table 1 and for plastic pipework
in table 2.
The preferred solution where
space will allow
The size of the distribution pipes supplying
the manifold should be calculated using
the method set out in BS 6700. A typical
diagrammatic arrangement of a system using
Manifold Type 1 is shown below.

Description
Individual capability
Balance
Position of back
Positioning of the arms and body
The hold
Taking the lead for team lifts
a.
Balance - Since balance depends essentially upon the position of the feet,
they should be apart about hip breadth with one foot advanced giving full
balance sideways and forward without tension.In taking up this position,
lifting is done by bending at the knees instead of the hips and the muscles
that are brought into use are those of the thigh and not the back.
b.
Position of back - Straight - not necessary vertical. The spine must be
kept rigid, this coupled with a bent knee position, allows the centre line of
gravity of the body to be over the weight so reducing strain.
c.
Positioning of arms and body - The further arms are away from the side,
the greater the strain on the shoulders, chest and back. Keep elbows close
to the body arms should be straight.
d.
The hold - Before lifting ensure you have a good hold.Two handles are
provided on Appliance products at the top rear side, these allow one or
two persons to have a purposely-designed hold at the top of the appliance
to ensure easy lifting at the top of the product.Each appliance is supplied
with a pallet, which has been attached to the unit via the packaging.The
pallet will also allow for one or two persons to get a good hold.
Page 29
Individual capability plays an important
part in handling these products.Persons
above average build and strength will
find it easier and should be in good
health.Persons below average build and
strength may require more rest periods
during the handling process.
Pregnant women should not carry out
this operation.
Persons who are not in good health
should seek medical advice prior to
commencing any lifting or manual
handling operation.
Residual risk
Following the guidelines given above will
reduce any risk to injury.
All persons carrying out this operation
must be fully trained and copies of the
specific risk assessment made available
for inspection and use in their training
process.
