Do not tamper with any of the safety valves fitted to the system. If a fault is suspected contact a competent Installer. DO NOT bypass the thermal cut-out(s) in any circumstances. Where the inlet supply to the Pressure Reducing Valve (PRV) is routed through a heated space and is fitted with a check valve or other fitting that would prevent backflow, high pressures can be experienced in the inlet pipe due to warming that can cause damage to the PRV or other fittings on the inlet supply.

Notes: 1. Indirect cylinders tested in accordance with BS EN 12897:2016. 2. Heat up time from cold through 45°C, based on a flow temperature of 80°C +/- 2°C & normal volume. 3. Although the primary coil pressure rating is 1.0MPa (10bar) the 2 port zone valve and coil compression nuts supplied with the cylinder is only rated 0.86MPa (8.6 bar).

Figure 5: Direct wiring schematic page 9 4. Description of the product 4.1 General description This product is a purpose designed unvented water heater. The unit has a stainless steel inner vessel, which ensures an excellent standard of corrosion resistance. The outer casing is a combination of resilient thermoplastic mouldings and pre-coated steel.
# It is advantageous in many mixer showers to have a balanced hot and cold water supply, in these instances a balanced cold water connection is available on the combination inlet valve. page 10 Limitations The cylinder should not be used in association with any of the following: # Solid fuel boilers or any other boiler in which the energy input is not under effective thermostatic control, unless additional and appropriate safety measures are installed.
Figure 6: Access schematic (not to scale) page 11 NOTE: A backflow prevention Device may include check valves, a water meter or an additional PRV Figure 7: Typical installation schematic (not to scale) 6.2 Water connections WARNING Under no circumstances should the factory fitted temperature/pressure relief valve be removed other than by a competent person.

WARNING: IF THERE IS AN UPSTREAM CHECK VALVE OR FITTING WHICH MAY PREVENT BACKFLOW THEN HIGH PRESSURES CAN BE EXPERIENCED DUE TO AMBIENT TEMPERATURES WHICH CAN CAUSE DAMAGE TO THE VALVES AND FITTINGS. Figure 8: Combination inlet valve page 13 Expansion vessel The expansion vessel accommodates expansion that results from heating the water inside the unit.

All electrical wiring should be carried out by a competent electrician and be in accordance with the latest I.E.E Wiring Regulations. Each circuit must be protected by a suitable fuse and double pole isolating switch with a contact separation of at least 3mm in both poles. DO NOT operate the immersion heaters until the cylinder has been filled with water.
# If necessary the temperature can be adjusted by inserting a flat bladed screwdriver in the adjustment spindle on front of the immersion heater thermostat and rotating. The adjustment represents a temperature range of 12°C to 72°C. # Check the operation of thermostat(s) and that no water has discharged from the expansion relief valve or temperature/pressure relief valve during the heating cycle.

Benchmark The cylinder is covered by the Benchmark Scheme which aims to improve the standards of installation and commissioning of domestic heating and hot water systems in the UK and to encourage regular servicing to optimise safety, efficiency and performance. Benchmark is managed and promoted by the Heating and Hotwater Industry Council.
Operational faults and their possible causes are detailed in the Fault Finding section (p.22) of this book. It is recommended that faults should be checked by a competent Installer. The air volume within the expansion vessel will periodically require recharging to ensure expanded water is accommodated within the system.
# Attach a hosepipe to the drain cock having sufficient length to take water to a suitable discharge point below the level of the unit. # Open a hot tap close to the unit and open drain cock to drain unit. If water fails to drain vent the unit manually by opening the temperature and pressure relief valve.
Page 29
# NEVER bypass any thermal controls or operate system without the necessary safety valves. # Water contained in the cylinder may be very hot, especially following a thermal control failure. Caution must be taken when drawing water from the unit. The fault finding chart (table 6, below) will enable operational faults to be identified and their possible causes rectified.
11. Decommissioning 11.1 Decommissioning procedure # Isolate electrical supplies and make safe # Isolate the water supply # Drain the cylinder # Drain the primary circuit (indirect only) # Remove cylinder # Cap pipework Environmental information Products are manufactured from many recyclable materials. At the end of their useful life they should be disposed of at a Local Authority Recycling Centre in order to realise the full environmental benefits.
