MANUAL HANDLING INSTRUCTIONS

ENGLISH FRANCAIS NEDERLANDS español ITALIANO deutsch 664Y4700 • D Description of the specifications: This wall hung electric boiler is available in 7 models: • The models Single phase 09 and 15 are supplied with 230 V. • The models Tri phase 09, 15 , 22, 28 and 36 are supplied with 400 V. The maximum power can be adjusted for all models by acting on the switches on the control panel. The maximum power can be adjusted for this models by acting on the terminals bridges. Models Adjustable power Min Max 09 single phase 5.6 kW 8.4 kW 15 single phase 9.6 kW 14.4 kW 22 tri phase 14.4 kW 21.6 kW 28 tri phase 14.4 kW 28.8 kW 36 tri phase 18 kW 36 kW Lining The boiler is protected by a steel lining that first of all undergoes a degreasing and phosphation process before being lacquered and burnt at 220°C. Heating body The boiler heat exchanger is constructed from mild steel with welded joints. It is hydraulic tested under a pressure of 4.5 bar (maximum working pressure = 3 bar). Heating elements Immersion heaters, constructed from stainless steel Incoloy 800 and mounted in the top of the boiler, provide the power source for the Boiler. Equipment The boiler is equipped with all the necessary components to allow direct connection to a heating system without the need for a feed and expansion cistern. These components include; primary 10 litre expansion vessel (suitable for a system water content of up to 160 litres), pressure and temperature gauge, safety valve, circulating pump, low water pressure switch, control and high limit thermostats, on/off and power level switches. CONNECTION The boiler is suitable for connection to most heating and hot water systems, with a maximum working pressure of 3 bar and a maximum temperature of 85°C. It can also be used in multiple boiler installations allowing greater outputs to be achieved. The boiler, and connection glands for both the main power supply and optional external controls are provided, suitable for single or three phase electrical supply depending upon boiler output required. An internal 3 amp MCB is provided to protect the internal control circuit, from which optional controls can be connected e.g. internal or external timeclock, room thermostat or Honeywell Sundial controls. DUAL STAGE THERMOSTAT The temperature of the boiler is controlled by a dual stage thermostat which is set by the user to give the desired boiler temperature. When the boiler has heated up to within 7°C of the set temperature, the thermostat switches off one power stage and therefore reduces the heat input. Thanks to this simple but effective form of modulation, the boiler has longer working cycles and requires less stops and starts, thus resulting in a more even temperature across the boiler. It also means less wear and tear on components and, importantly it uses less power once it has reached working temperature. certification The boilers have been manufactured to comply with the following standards BS EN60335-2-35: 1998, BS EN55014-2:1997 and BS EN50081-1-1: 1992.

The following instructions assume that the boiler has been commissioned, and that the system is filled with water and has been fully vented. SETTING UP • Before switching on any electrical supplies to the boiler ensure that the combined temperature and pressure gauge reads at least 1 bar and the control thermostat is set to the desired temperature. • If an internal time clock is fitted ensure that this is switched on (see “Optional Internal Time Clock”) and if any other auxiliary controls are fitted e.g. programmer, room thermostats, cylinder thermostats etc, consult appropriate manufacturers’ instructions to switch these on. • Switch on any local means of isolation to boiler. • Switch the boiler on using the ON/OFF switch (the neon light on the switch should now glow). • Turn on both power level switches - after a short period of time the boiler temperature should start to rise, indicated by the combined temperature and pressure gauge. If the boiler fails to operate, the overheat safety thermostat should be checked. Access to the thermostat reset button is obtained by unscrewing (anti-clockwise) the domed button cover on the front panel (a screwdriver is not required).The reset button can then be seen - press the button, a click should be heard and the button is reset. If no click was heard the device is not at fault and further investigation is required by a suitably qualified engineer. • The internal clock or external programmer can now be set to allow on/off periods as desired. The ON/OFF switch and 2 power level switches should be left in the ON position during normal use. The power level switches will automatically switch on and off during normal boiler operation, depending on boiler temperature. • If the boiler is not in regular daily use during cold periods, it is recommended that it be fitted with a frost sensing thermostat to override the timeclock and prevent the system from freezing. • As with most boilers and heating appliances the casing and pipework can get hot during normal running so the boiler must not be covered and the surrounding area must be kept clear. optional internal timeclock • This operates on a 24-hour sequence. Around- the outside of the clock there are a number of white tabs - these allow 15 minute switching times.To set a boiler cycle simply push outwards the number of tabs required for your heating period. Remember : tab OUT = BOILER ON tab IN = BOILER OFF The time of day is marked by an arrow on the inner part of the clock - set the outer time to coincide with this arrow. On the centre part of the clock there is a switch. This has three positions : • Switch down - timeclock off • Switch middle - timeclock timed (normal position) • Switch up - timeclock on constant. PRESSURE IN THE HEATING SYSTEM The CH pressure must be a minimum of 1 bar and must be checked by the end user on a regular basis. If the pressure drops under 0.5 bar, the integrated water pressure switch blocks the appliance until the pressure in the system returns to a level above 0.8 bar. The installer fits the system with a separate fill valve underneath the appliance. Make sure that the appliance is powered off when filling the system. To do this, turn the on/ off switch. For more information, please ask your installer when the system is delivered. A safety valve is provided underneath the appliance. If the system pressure exceeds 3 bars, this valve opens and drains the water from the system. In this case, please contact your installer. instructions LEGEND 1. ON/OFF switch 2.

ENGLISH FRANCAIS NEDERLANDS español ITALIANO deutsch 664Y4700 • D COMMISSIONING - WATER 1. The system must be thoroughly cleansed prior to connection of the boiler. The system water should be treated to prevent general corrosion and deposition of scale or sludge in the boiler, please refer to BS7593. If installing the boiler onto an existing system, ACV recommend that an approved system cleaner is used. 2. Fill and pressurise the boiler and system to 1.5 bar, making sure to vent the boiler via the automatic air vent on top of the boiler. Note that the black dust cap on the air vent should be left loose to allow the auto vent to function. 3. Check for leaks. For specialist advice on water treatment products, contact: Fernox, Britannia Works Clavering, Essex CB11 4QZ Tel 01799 550811 COMMISSIONING - ELECTRICAL The Electrical installation supplying this boiler must conform to the current IEE Regulations. 1. Remove the front panel and check all electrical connections for tightness. 2. Ensure all internal relays, contactors etc are secure on the DIN rails. 3. Set all panel control switches to off. 4. Check the power stage delay timer settings - Adjuster (A) is factory set to the 1 to 10 minute position which is the optimum setting for the boiler and should be verified during commissioning. - Adjuster (B) is used to set the DELAY ON time of the following stage contactors, the available settings are in 1 minute increments if A is set to 1 to 10 minutes. This function is particularly useful in areas where gradual switching of electrical load is required and the resulting maximum demand kept to a minimum.The timers add to the flexibility of the installation but must be optimised by a qualified engineer.The normal setting is 1. 5. Set internal MCB to off position. 6. Set the control thermostat to desired temperature. STARTING THE BOILER 1. Switch on the internal or external timeclock (if fitted) 2. Switch on internal MCB 3. Switch on local isolator to boiler 4. Turn the boiler on using the ON/OFF switch 5. Switch on the power levels switch stage 1, the first stage contactors will energise 6. Switch on the power levels switch stage 2, after a short delay the second stage contactors will energise. Note: the power stage delay timer settings should be verified as shown in item 4 under “Commissioning - Electrical” 7. The boiler temperature will now rise as indicated by the combined temperature and pressure gauge 8. The temperature will continue to rise until the control thermostat temperature setting is reached then the boiler will switch off. Once these procedures have been followed the system can be left to operate normally by the following method. 1. Ensure that boiler thermostat is set to the desired temperature 2. Turn the boiler on using the ON/OFF switch 3. Turn on power level switch 1 4. Turn on power level switch 2 5. Set timeclock (if fitted) and/or external controls to desired boiler operating on/off times. After one week of operation all electrical connections should be re-checked for tightness and the boiler water system checked for leaks and air and rectified if necessary. MAINTENANCE For safety reasons it is recommended that the boiler is serviced annually and that servicing is carried out by a qualified service engineer. Before carrying out any work on the system ensure that the boiler is cool and all electrical supplies are isolated. 1. After removing front cover undo the four screws retaining the front control panel and gently let the panel suspend on the wiring to the rear of the panel. Undertake a visual inspection of the boiler looking out for signs of water leakage from joints, expansion vessel, and the area around the elements on top of the boiler. 2. Undertake a visual inspection of all cabling in the boiler casing checking for signs of overheating or burning. 3. Check all push-on electrical connectors for tightness and good connection to the relative components. 4. Using a correct fitting screwdriver check all electrical terminals on DIN rails and on all components for tightness. 5. Check the settings on the internal timers in accordance with the “Commissioning - Electrical” section. 6. Replace the control panel and the boiler front cover and refit screws. 7. Reinstate the electrical supply and follow the procedures set out in the commissioning section. commissioning and maintenance A B
