GENERAL PRODUCT DESCRIPTION

These instructions will guide you through the installation, maintenance, and use of the Zip Aquapoint III, however, if you require any further information please call Zip customer service on 0345 6 005 005.

• The Zip Aquapoint III 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 impact-resistant plastic and heat losses are minimized by the high-efficiency polyurethane foam insulation.
• The inner vessel is constructed from a glass-enameled 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 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 as part of the preventative maintenance program.

If the hot water system has not been 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, clotheswasher, or other appliance be used before the heater is returned to service.

APPROVALS
The Aquapoint III models are approved to the LVD and EMC directives and CE endorsed. The Aquapoint III models have been examined, tested, and found when correctly fitted to comply with the requirements of the United Kingdom Water Regulations / Byelaws (Scotland). The products are listed under the WRAS (Water Regulations Advisory Scheme) Water Fittings and Materials Directory.

INSTALLATION

Requirements

• Before starting installation the WARNINGS and CAUTIONS should be read and fully understood. If in doubt, or need of further guidance, please call Zip Customer Service on 0345 6 005 005
• Installations must comply fully with UK Water Regulations, Building regulations part G3, and any Local Authority requirements.
• The electrical installation including earthing and cross-bonding should comply with the current IEE regulations and any Local Authority requirements.
• The Zip Aquapoint III is designed for connection directly 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 pipework provided that no check valve, stop valve with a loose jumper or another fitting can prevent reverse flow. [See diagram 1, (Fig.2) on page 12].
• Where the expanded water cannot be accommodated in the pipe work and the static water supply pressure is under 3.5 bar, fit accessory pack AQ2 (expansion vessel and check valve). Where static water pressures are likely to exceed 3.5 bar fit accessory pack AQ2 and AQ3 (pressure reducing valve and line strainer).[See diagrams 2&3 (Fig.2) page 12].
• If required a temperature and pressure relief valve (accessory AQ1) can be used with any installation by fitting securely into the locating point provided.
• The 6-bar expansion relief valve must be fitted 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 fitted between the expansion relief valve and the storage cylinder.
• The installations must comply fully with UK Water Regulations, Building regulations part 3, and any Local Authority requirements. The point of discharge must be in a safe and visible position. The connection should be made using a 15mm pipe having a continuous fall to a maximum length of 3 meters. It shall not have more than 3 right-angled bends. If a waste connection over 3 meters is necessary, the pipe diameter should be 22mm with continuous fall and no more than 4 right-angled bends with maximum resistance to flow equivalent to 9 meters of straight pipe.
• An isolating valve must be fitted to the cold water supply.
• Valves and fittings must be of a type required by the Water Supply Regulations.

Positioning

• The 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.

• 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.
  Note: Undersink and oversink models are not interchangeable. The fixings must be capable of supporting the heater when full of water (see Technical data page 4).

• 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 at the rear of the casing. As shown in Fig.1 below.

• Always position the Aquapoint III to allow for its removal for future inspection and maintenance.

• The Aquapoint III is not recommended for installation above false ceilings.

• Do not install in a location where this unit or connecting pipelines can freeze.

• When considering the location of the heater, consideration should be given to the safe and visible disposal of any water resulting from leaks and seepage. This is particularly relevant when the heater is located in a roof space, cupboard or any concealed location. For guidance please call Zip Customer Service on 0345 6 005 005.

Wall Mounting

The unit will be supported by being hung on a bracket fixed to a support wall, using the fixings provided, as shown in Fig.1, page 10. Therefore it is important to ensure that the wall is 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’ are located into the slots provided in the back of the unit, allowing the unit to hang flat against the wall.

Note: It is not necessary to remove the casing to mount the water heater on the wall bracket.

Plumbing and safety control arrangement

• Check the incoming water supply pressure concerning the table and diagrams in Fig.2, page 12 to determine the layout required, bearing in mind that mains water supply pressure can increase considerably at night.
• Refer to the diagrams in Fig.2, page 12 to determine the accessories required to suit your layout
• Position the heater and controls to allow for future maintenance.
• All control and safety valves are marked with the direction of flow 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.
• To ensure a watertight seal use fifiberashers 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 plumber paste to secure the joints as this can impair the operation of any valves connected to the heater.
• An isolating service valve (not supplied) should be fitted in the cold water supply pipework as shown in all 3 diagrams in Fig.2, page 12.
• Flush all pipe work thoroughly before making the final 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.
• Drain valves should be fitted in both hot and cold water lines.

PLUMBING INSTALLATION DIAGRAM

Zip recommends 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, and mounted vertically on pipework to minimize any trapping of debris and to minimize the volume retained within them, with an isolation and drain valve to aid flushing and sampling and designed to stimulate flow within the vessel.

ELECTRICAL INSTALLATION

It is recommended that the electrical installation is carried out by a qualified electrician. The electrical installation including earthing and cross-bonding must be carried out to comply with the current IEE regulations and Local Authority requirements.

• Switch off the mains electrical supply before carrying out any work involving a live circuit 230V AC supply only, this appliance must be earthed.

The Zip Aquapoint III is pre-wired with a length of 3-core cable suitable for connection to a mains 230V AC supply. The cable is to be wired to a double pole fused spur, with a minimum break rating of 13 amps. If the cable length is insufficient it is recommended that the entire length of cable is replaced with no joins to the original. To replace the cable:

• Prise the temperature control knob off the spindle and remove the screw underneath. Release the two fixing screws at the top of the cover assembly.
• Remove the cover by lifting forwards and upwards.
• Release the locknut on the cable grommet assembly.
• Remove the existing cable and pass the new cable through the grommet assembly
• Remake the cable connections and tighten the grommet locknut to ensure the cable is securely clamped
• Re-assemble the cover.

All internal wiring is factory mounted and should not be altered or modified.

• This appliance must be earthed. Do not switch on the electrical supply until the water heater is full of water.

Wiring Diagram

Safety cut-out
In the event of a malfunction that leads to an over temperature situation, a Safety cut-out will automatically cut off the electrical supply to the element. This is a manually resettable cut-out that may be reset by a qualified electrician once the fault has been corrected.

COMMISSIONING AND OPERATION

• Check that all Installation requirements have been met.
• Check that all water and electrical connections are correct and tight.
• Open a hot water tap.
• Open the water mains isolating valve and allow the heater to fill.
• Close the hot water tap when water starts to flow from it.(The heater vessel should now be full).
• Check for leaks and rectify as necessary.
• Manually operate the Expansion Relief Valve and T&P Valve if fitted to ensure free water flow through the discharge pipe by turning the knob to the left and holding it in the open position.
• Set the temperature control knob to the required position. The economy ‘e’ setting will maintain the most economical stored water temperature at approx. 41°C for models AP/05/OB, AP3/05 or 35°C for models AP3/10/OB, AP3/10, AP3/15/OB, AP3/15. 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 75°C.

Note

• Rotating the temperature control knob varies the temperature over the range of 9°C to 75°C.
• To protect the water heater from freezing, the temperature control knob may be set to when a stored water temperature of approximately 9°C will be maintained while the heater is connected to the power supply. This protection does not extend to the pipework and fittings.
• The maximum stored water temperature can be limited as follows.
• Insert screwdriver in slot ‘1’ and remove cover ‘2’.
• Set knob limiter ‘3’ to any desired temperature value.
  • C – 35°C
  • B – 45°C
  • A – 55°C
  • – 75°C
• Replace cover ‘2’.

COMMISSIONING AND OPERATION

• Switch on the electrical supply to the unit. The red neon light will glow during the heating cycle and will extinguish when the selected temperature is reached re-lighting again for the next heating cycle.
• During the heating cycle, no water should escape to waste from either the expansion relief or T&P valves.
• Allow the heater to reach the selected temperature and when the indicator light has extinguished, check the water temperature and re-check the water connections adjusting as necessary.
• Please pass these instructions on to the person responsible for the building and ititsanagement.

MAINTENANCE

Precautions

• The Zip Aquapoint III is an unvented electric water heater and only a competent person (electrician or plumber), familiar with unvented systems, should carry out any servicing and maintenance work on this unit.
• DO NOT Remove the cover whilst the unit is connected to the electrical supply.
  • 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.
• The over-temperature safety cut-out reset is located inside the cover. DO NOT reset the over-temperature cut-out until the cause of its operation has been correctly diagnosed and corrected.
• 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 it back on until a competent person (electrician or plumber), has checked that it is safe to do so.
• 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.
• DO NOT block or restrict the discharge from any safety valve.
• DO NOT tamper with any safety valve.
• 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.
• Please note that limescale forms more readily at higher temperatures. Damage or failures caused by the formation of limescale are specifically 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.

Schedule
It is recommended that all key components of the heater should be inspected regularly, no greater than 12 monthly intervals, for the continued safe and efficient 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:

• Sacrificial anode. The condition of the anode should be checked regularly as part of the preventative maintenance program, to ensure its effectiveness in protecting the vessel and element from corrosion.
  To check the condition of the anode visually through the flange opening, first, remove the thermostat temperature probe and disconnect the electrical wires to the element before unscrewing the element assembly and removing it.
  To check the condition of the anode electrically, disconnect the wire between the anode and the vessel and check that the current between the anode and vessel exceeds 0.4mA. Ensure that the wire is reconnected afterward.
  If the current between the anode and the vessel does not exceed 0.4mA it should be checked visually and if badly corroded, it should be replaced.
  To replace the anode, grasp it with long tongs or another suitable tool through the flange opening and unscrew the securing nut whilst, at the same time supporting the anode from inside the vessel.

• Expansion relief valve. Check correct operation.

• T&P relief valve, if fitted. Check correct operation.

• Expansion vessel, if fitted. Check pressure-referring to the label on the side of the vessel.

• Integral line strainer, if a pressure-reducing valve is fitted. Inspect and clean as necessary.

• Check the discharge pipe is free of obstructions.

• Check that all the electrical connections are tight.

De-Installation

• Switch off and disconnect the electrical supply.
• Close the mains water supply isolating valve.
• Disconnect the inlet and outlet connections on the heater.
• Remove the heater.
• Drain the unit through the hot water supply connection
