These instructions will guide you through the installation, maintenance and use of the
Zip Aquapoint III Eco, however, if you require any further information please call Zip
customer service on 0345 6 005 005.
• The Zip Aquapoint III Eco is an unvented water heater designed for connection directly
to incoming mains water supply and can serve one or more outlets using conventional
taps.
• Care should be taken that the unit being chosen can meet the demands of the outlets
being supplied.
• The casing is constructed of powder coated steel and heat losses are minimised by the
high efficiency polyurethane foam insulation.
• The inner vessel is constructed from glass enamelled steel sheet and pressure tested to
1.2 MPa (12 bar).
• A manually resettable safety cut out automatically cuts off the electrical supply to the
heating element in the event of a malfunction.
• A sacrificial magnesium anode is fitted to the vessel to provide anti-corrosion protection
for the vessel and the heating element.
Gradual erosion of the anode will occur depending on local conditions and in extreme
cases, conditions may cause rapid erosion resulting in particles being deposited as a
residue or emitted from the heater.
The Aquapoint III Eco should not therefore, be used in applications where the quality
of the water is paramount. Regular preventative maintenance inspections are vital to
achieve optimum performance and durability of the appliance.
The condition of the anode should be checked regularly by an authorised Zip service
provider as part of the preventative maintenance programme.
If the hot water system is not used for two weeks or more, it is recommended
that a hot tap be turned on for several minutes at a sink, basin or bath, it is not
recommended that either a dishwasher, clothes washer or other appliance be used
before the heater is returned to service.
The Zip Aquapoint III Eco must be installed in accordance with these instructions and
all current legislation, codes of practice and regulations governing the installation of
unvented hot water cylinders in force at the time of installation.
Please contact Zip Customer Service for advice on 0345 6 005 005.
Approvals
Zip Aquapoint III Eco complies with LVD and EMC directives and is CE endorsed.
Zip Aquapoint III Eco has been examined, tested and found, when correctly fitted,
to comply with the requirements of the United Kingdom Water Regulations/Byelaws
(Scotland). The product, therefore, is listed under the WRAS (Water Regulations Advisory
Scheme) Water Fitting and Materials Directory.

Zip recommend expansion vessels to be installed in line with the current HSE
guidelines. Expansion vessels should be installed, in cool areas on cold flowing pipes,
mounted as close to the incoming water supply to the water heater as possible, mounted
vertically on pipework to minimise any trapping of debris and to minimise the volume retained
within them, with an isolation and drain valve to aid flushing and sampling and designed to
stimulate flow within the vessel.

Requirements
Prior to installation the Zip Aquapoint III Eco should be kept upright in its original packaging
and handled with care always lifting from underneath.
The Zip Aquapoint III Eco should be stored in a covered, dry area protected from the weather.
These instructions must be read and fully understood before commencing the installation. If in
doubt, or in need of further guidance please ring Zip on 0345 6 005 005.
Installation must only be undertaken by a competent person holding a current Registered
Operative Identity card for the installation of unvented domestic hot water storage systems
issued by an accredited body.
The Zip Aquapoint III Eco must be installed in accordance with these instructions and all
current legislation, codes of practice and regulations governing the installation of unvented
hot water cylinders in force at the time of installation.
All connections should be made to the Zip Aquapoint III Eco and its safety devices using the
15mm or 22mm compression fittings, nuts and olives supplied.
The electrical installation including earthing and cross bonding must comply with the current
IEE regulations and any Local Authority requirements.
The cold water inlet set assembly comprises a pressure reducing valve with integral strainer,
expansion relief, check valve and expansion vessel. All of these components must be included
in the installation. The pressure settings on these components are factory set and indicated
on the top of the valve. Do not break any seals or attempt to adjust any safety valve; to do so
may impair the safety of the installation and will invalidate the warranty.
It is recommended that the unit is installed according to these instructions.
Under no circumstances should the expansion relief valve be installed in an inverted position
as fouling of the seat caused by deposits may prevent it from operating correctly.
Safety relief valve connections should not be used for any other purpose and no valve should
be fitted between the expansion relief valve and the storage cylinder.
An isolating valve must be fitted to the cold water supply to the inlet manifold.
The Zip Aquapoint III Eco is designed for use with a supply pressure up to 1.2 MPa (12 bar).
For supply pressures exceeding 1.2 MPa (12 bar) an additional pressure reducing valve must

Discharge arrangement
1. Must conform to current regulations.
2. The expansion relief, temperature and pressure relief valves should drain via a tundish
which should be installed in a visible location and away from any electrical devices.
3. The discharge pipe from the tundish should terminate in a safe place where there is no risk
to persons in the vicinity of the discharge, be of metal and:
a) 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. Discharge
pipes between 9m and 18m equivalent resistance length should be at least 2 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 diagram of typical discharge pipe arrangement and table for sizing copper discharge pipe
on page 13.
b) Have a vertical section of pipe at least 300mm long, below the tundish before any elbows
or bends in the pipework.
c) Be installed with a continuous fall.
d) Have discharges visible at both the tundish and the final point of discharge but where
this is not possible or it is practically difficult there should be clear visibility at one or other
of these locations. Examples of acceptable discharge arrangements are:
e) Ideally below a fixed grating and above the water seal in a trapped gully.
f)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.
g) Discharges at high level: e.g. into metal hopper and metal down-pipe with the end of the
discharge pipe clearly visible (tundish visible or not) or onto a roof capable of withstanding
high temperature discharges of water and 3m from any plastic guttering system that
would collect such discharges (tundish visible).
h) Where a single pipe serves a number of discharges, such as in blocks of flats, the number
served should be limited to not more than 6 systems so that any installation can be traced
reasonably easily. The single common discharge pipe should be at least one pipe
size larger than the largest individual discharge pipe to be connected. If unvented hot
water storage systems are installed where discharges from safety devices may not be
apparent e.g. in dwellings occupied by blind, infirm or disabled people, consideration
should be given to the installation of an electronically operated device to warn when
discharge takes place.
Note: The discharge would consist of high temperature water and steam. Asphalt, roofing
felt and non-metallic rainwater goods may be damaged by such discharges.
Note: It is not acceptable to discharge straight into a soil pipe. For guidance See G3 3.60.

water connections underneath.
The unit is designed to be wall mounted using the wall fixings supplied with the product.
Ensure that the wall where the unit is to be located is sufficiently strong to support the full
weight of the unit (see Technical data table, page 4) and capable of accepting suitable fixings.
Position the Zip Aquapoint III Eco to allow for provision of the cold water supply, discharge
fittings and pipework as well as access for future maintenance, repair of the unit or its
replacement.
Reasonable clearance will be required to give access to pressure controls, element assembly,
draining facility, pipe connections and expansion vessel.
A gap of 250mm should be left between the top of the unit and the ceiling. A gap of 350mm
should be left between the bottom of the unit and any floor or work surface.
Do not install in a location where the unit or connecting pipework can freeze.
Fix the Zip Aquapoint III Eco hot water cylinder locating bracket to the wall with suitable
fixings as shown in the diagram and table of dimensions on page 4 & 5.
Position the Zip Aquapoint III Eco securely on the locating bracket.
The expansion vessel should be securely fitted to a suitable and convenient wall using the
fittings supplied and positioned to enable its connection to the cold inlet set.
When deciding the final location of the heater consideration should be given to the safe and
visible disposal of any water resulting from leaks or seepage.
This is particularly relevant when the heater is located in a roof space, cupboard or any
concealed location.
For guidance please call Zip Water UK on 0345 6 005 005.
Plumbing
1. The unit should be provided with a continuous cold water supply via 22mm pipework.
2. The water connections are 1/2” BSP at the bottom of the appliance. When viewed from
the front, the cold feed connection is to the right and colour coded blue, the hot outlet
from the heater is to the left and colour coded red.
3. The inlet and outlet pipes to the heater should be sealed using fibre washers. Complete
the seal by applying PTFE tape to the threads, but do not over apply or extend beyond the
limits of the thread as this will lessen the effectiveness of the joint.
4. An isolating valve (not supplied) should be fitted in the cold water supply pipework to the
inlet manifold assembly to enable isolation of the water supply to the unit for servicing or
replacement.

5. Open hot water taps.
6. Open the cold water supply valve and permit the heater to fill.
7. Leave hot taps open until all air has been purged from the system and water is flowing
freely from all outlets.
8. Check for leaks and rectify as necessary.
9. Check the operation of both the T&P relief valve and the Expansion Relief Valve to ensure
free water flow through the discharge pipe by turning the knob to the left and holding in
the open position.
10. Set the temperature control to the desired setting. The economy ‘e’ setting will maintain
the economical stored water temperature at approx. 55ºC. Lime-scale formation and
heat loss are minimised at the economy ‘e’ setting, however the operating temperature
may be increased as required to a maximum of 75ºC.
11. Switch on the electrical supply to the unit. The pilot light will illuminate to indicate that
the elements are operating.
12. During the heating cycle no water should escape to waste from either the expansion
relief or T&P relief valves.
13. Allow the heater to reach the selected temperature when the pilot light will extinguish.
Check the water temperature and re-check water connections adjusting as necessary.
14. Pass these instructions to the person responsible for the building management.

1. The Zip Aquapoint III Eco is an unvented electric water heater and a competent person,
familiar with unvented systems, should carry out all of the servicing and maintenance.
2. Do not remove the electrical cover panel whilst the unit is connected to the electrical
supply.
3. Do not reset the over temperature cut-out until the cause of its operation has been
diagnosed and necessary repairs have been undertaken.
4. Do not use the water heater if it is suspected of being frozen. Switch off the electrical
supply if water ceases to flow and do not switch on again until a competent person has
checked that it is safe to do so.
5. The heater should be visually inspected regularly in line with local regulations. This is
particularly important if the heater is located in a cupboard, roof space or any other
concealed location. If there is any sign of leaks or seepage the heater should be isolated
from the water supply and switched off from the electrical supply until a competent
person has investigated the cause.
6. Do not block or restrict the discharge from any safety valve.
7. Do not tamper with any safety valve.
8. If water discharges from any safety valve switch off the electrical supply to the unit,
isolate the water supply and contact a competent person familiar with unvented
systems.
9. Please note that lime-scale deposits form more readily at higher temperatures. Damage
or failures caused by the formation of lime-scale are specifically excluded under
the terms of the warranty. To reduce lime-scale formation to a minimum the unit should
always be operated at the lowest convenient temperature.
10. If the unit has been commissioned and is to be unused for more than two weeks with
the power supply still connected the thermostat should be set to ‘ ’ to maintain a
temperature of approx. 9ºC and protect the unit from freezing. Note: this protection does
not extend to connecting pipework. It is recommended that the cold supply is turned off
and several litres of water drawn off through a hot tap. Note: The cold supply must be
re-opened prior to use. If power has been disconnected it is recommended that the unit
is drained (see draining).
11. The Zip Aquapoint III Eco is fitted with a sacrificial anode to provide additional protection
against corrosion. Gradual erosion of the sacrificial anode will occur depending upon
local conditions which in extreme cases may cause rapid erosion of the anode resulting
in particles being deposited as a residue. The Aquapoint III Eco should not, therefore,
be used in applications where water quality is critical. Regular preventive maintenance
inspections are vital to achieve optimum performance and durability of the appliance.
The condition of the anode should be checked regularly by an authorised Zip service
provider as part of the preventive maintenance programme.

It is recommended that all key components of the heater should be inspected on a regular
basis, no greater than twelve monthly intervals, for continued safe and efficient operation.
The inspection should be carried out by a competent person familiar with unvented systems
and the components to be inspected should include the following:
1. Expansion relief valve. Check for correct operation.
2. T&P relief valve. Check for correct operation.
3. Check expansion vessel pressure – refer to label on vessel for correct pressure.
4. Inspect integral line strainer and clean as necessary.
5. Check that the discharge pipework is free of any obstructions.
6. Check that all electrical connections are tight.

LIVE TESTING
7. Check condition of the sacrificial anode by disconnecting the wire between the anode
and vessel and verifying that the current between anode and vessel exceeds 0.1mA
ensuring that the wire is re-connected afterwards. If the current between anode and
vessel does not exceed 0.1mA the anode should be checked visually and replaced if
necessary.
Draining
To drain the unit:
1. Isolate the electrical supply.
2. Isolate the mains cold water supply to the unit.
3. Open a hot water tap.
4. Remove the plug from the drain point on the heater.
