Installation
1. Before starting installation the WARNINGS (page 3) and CAUTIONS (page
4) should be read and fully understood. If in doubt , or in need of further guidance,
please call Zip Customer Service on 0845 6 005 005.
2. Installations must comply fully with UK Water Regulations, Building regulations part G3
and any Local Authority requirements.
3. The electrical installation including earthing and cross bonding should comply with the
current IEE regulations and any local authority requirements.
4. The Zip Aquapoint III is designed for connection direct to the incoming mains water
supply and accommodation must be made for the expanded water that will occur
with each heating cycle. Regulations permit expanded hot water to be accommodated
within the supply pipe work provided that no check valve, stop valve with loose jumper
or other tting can prevent reverse ow. [See diagram 1, (g.2) on page 10].
5. Where the expanded water cannot be accommodated in the pipe work and the static
water supply pressure is under 3.5 bar, t accessory pack AQ2 (expansion vessel and
check valve). Where static water pressures are likely to exceed 3.5 bar t accessory
pack AQ2 and AQ3(pressure reducing valve and line strainer).[ see diagrams 2&3 (g2)
page 10]
6. If required a temperature and pressure relief valve (accessory AQ1) can be used with any
installation by tting securely into the locating point provided.
7. The 6 bar expansion relief valve must be tted on the cold water supply.
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.
The 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.
8. The drain connection from the expansion relief valve and the T&P valve, if fitted,
must be in accordance with the water supply regulations. The point of discharge
must be in a safe and visible position. The connection should be made using 15mm
pipe having a continuous fall to a maximum length of 3 metres. It shall not have
more than 3 right-angled bends. If a waste connection in excess of 3 metres is
necessary, the pipe diameter should be 22mm with continuous fall and no more
than 4 right-angled bends with a maximum resistance to flow equivalent to 9 metres
of straight pipe.
9. An isolating valve must be tted to the cold water supply.
10. Valves and ttings must be of a type required by the Water Supply Regulations.
Requirements
Instructions. V1.01 Page 8 JULY / 2013
1. The Zip Aquapoint III must be installed vertically. The connections should be at the rear
of the unit. When facing the heater the hot supply (red) is to the left and the cold supply
(blue) is to the right.
2. The heater may be mounted above or below the intended outlets providing the
water connections for the undersink models are at the top and for the oversink
models underneath.
NB. Undersink and oversink models are not interchangeable.
The xings must be capable of supporting the heater when full of water (see Technical
data page 5).
3. The undersink unit can be placed unsupported on the floor or cupboard base, but if
additional support is required, securing screws are supplied that locate to the rear

Positioning
Instructions. V1.01 Page 9 JULY / 2013
1. Check the incoming water supply pressure with reference to the table and diagrams on
the following page to determine the layout required bearing in mind that mains water
supply pressure can increase considerably at night.
2. Refer to the diagrams in (g.2) to determine the accessories required to suit your layout
3. Position the heater and controls to allow for future maintenance.
4. All control and safety valves are marked with the direction of ow and will not function if
incorrectly orientated. 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.
5. To ensure a watertight seal use bre washers for connecting the inlet and outlet pipes to
the heater. Complete the seal by using PTFE tape to the threads but do not over apply or
extend beyond the thread limits as this will lessen the effectiveness of the joints. Do not
use plumbers paste to secure the joints as this can impair the operation of any valves
connected to the heater.
6. An isolating service valve (not supplied) should be tted in the cold water supply pipe
work as shown in all 3 diagrams in (g.2).
7. Flush all pipe work thoroughly before making the nal connections to the valves,
accessories and cold feed to the heater to ensure that any debris is removed. Failure to
do this may result in irreparable damage to the controls and will invalidate the warranty.
Plumbing and safety control arrangement
The unit will be supported by being hung on a bracket xed to a support wall, using
the xings provided, as shown (g.1). Therefore it is important to ensure that the wall
is strong and solid enough to fully support the unit when the tank is full.
It is important to ensure when drilling the wall, that the selected position avoids any
pipe work or electrical cabling. To mount the heater, the bracket ‘hooks’ locate into
the slots provided in the back of the unit, allowing the unit to hang at against the
wall.

(electrician or plumber), familiar with unvented systems, should carry out any servicing
and maintenance work on this unit.
2. DO NOT Remove the cover whilst the unit is connected to the electrical supply.
WARNING When the neon indicator light is extinguished the unit is still connected
to the electrical supply, only by operating the ‘double pole isolating switch’ can the unit
be disconnected from the supply.
3. The over temperature safety cut-out reset is located inside the cover. DO NOT reset the
over temperature cut-out until the cause of it’s operation has been correctly diagnosed
and corrected.
4. DO NOT use the water heater if it is suspected of being frozen. Switch off the electrical
supply if water ceases to ow and do not switch it back on until a competent person
(electrician or plumber), has checked that it is safe to do so.
5. The heater should be visually inspected regularly. This is particularly important if the
heater is located in a cupboard, roof space or any other concealed location. If there are
any signs of leaks or seepage the heater should be isolated from the water supply and
switched off from the electrical supply until a competent person (electrician or plumber),
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 (electrician or plumber)
familiar with unvented systems.
9. Please note that limescale forms more readily at higher temperatures. Damage or
failures caused by the formation of limescale are specically excluded under the
terms of the warranty. To reduce limescale formation to a minimum the unit should
always be operated at the lowest convenient temperature. The ‘E’ temperature setting
is recommended.
Instructions. V1.01 Page 14 JULY / 2013
Schedule
It is recommended that all key components of the heater should be inspected on a
regular basis, no greater than 12 monthly intervals, for the continued safe and efcient
operation of the unit. The inspection should be carried out by a competent person
(electrician or plumber) familiar with unvented systems and the components to be
inspected should include the following:
1. Sacricial anode. The condition of the anode should be checked regularly by an
