Installation
Requirements
General
Prior to installation the Zip Aquapoint should be kept upright in its original packaging and
handled with care always lifting from underneath.
The Zip Aquapoint should be stored in a covered, dry area protected at all times 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 0845 6024533.
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 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 and its safety devices using the 15mm
or22mmcompressionttings,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ttedbetweentheexpansionreliefvalveandthestoragecylinder.
Anisolatingvalvemustbettedtothecoldwatersupplytotheinletmanifold.

AP3/30_AP3/50_AP3/80_AP3/100_Instructions. V1.01 Page 8 August / 2012
The Zip Aquapoint 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
bettedinthecoldwatersupplytotheunit.
Secondary Circulation
The Zip Aquapoint is not recommended for use with secondary circulation systems.
Discharge
Discharge arrangement
The expansion relief and temperature and pressure relief valves should drain via a tundish
which should be installed in a visible location and away from any electrical devices.
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owresistance.
See diagram of typical discharge pipe arrangement and table for sizing copper discharge pipe
on page 9.
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nalpointofdischargebutwhere
 thisisnotpossibleoritispracticallydifcultthereshouldbeclearvisibilityatoneorother
of these locations. Examples of acceptable discharge arrangements are:
1. Ideallybelowaxedgratingandabovethewatersealinatrappedgully.
2. Downward discharges at a low level: i.e. up to 100mm above external surfaces such as
car parks, hard standings, grassed areas etc. are acceptable providing that where children
may play or otherwise come into contact with discharges, a wire cage or similar guard is
positioned to prevent contact, whilst maintaining visibility.
3. 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).
4. Whereasinglepipeservesanumberofdischarges,suchasinblocksofats,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,inrmordisabledpeople,consideration
should be given to the installation of an electronically operated device to warn when
discharge takes place.

AP3/30_AP3/50_AP3/80_AP3/100_Instructions. V1.01 Page 9 August / 2012
Note:Thedischargewillconsistofscaldingwaterandsteam.Asphalt,roongfeltand
non-metallic rainwater goods may be damaged by such discharges.
Note: It is not acceptable to discharge straight into a soil pipe. See G3 3.60 for guidance.

mains cold water supply. Partly drain
the unit. Recharge the expansion
vessel to the specied pressure and
re-commission.
Fault Finding
Note: All servicing and repairs must be undertaken by a competent person, familiar with
unvented systems.
11.TheZipAquapointisttedwithasacricialanodetoprovideadditionalprotectionagainst
 corrosion.Gradualerosionofthesacricial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 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.
Schedule
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efcient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.
7. Checkconditionofthesacricial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.
