HOW TO INSTALL YOUR IL095 WARNING: ALL WIRING AND INSTALLATION MUST BE SUPERVISED BY A SUITABLY QUALIFIED PERSON. WARNING: DO NOT INSTALL THIS UNIT WHERE IT MAY BE SUBJECTED TO FREEZING CONDITIONS. BEFORE YOU START Check that the mains electric is capable of supplying the required current. See the rating plate for current requirements. Check the pressure of the main water supply. To operate correctly, the unit requires the following running pressures.
Deciding the wiring route • You have a choice of whether to feed the electric cable through the side or through the back of the unit. • If it going through the side of the unit, cut out the plastic lug to expose the grommet (diagram 2). • If is going through the back of the unit, cut through the grommet on the backplate with a sharp knife (Take Care!). Make sure you do not remove the grommet from the backplate (diagram 3). Feed the cable through the grommet before you fix the unit to the wall.
WARNING: ENSURE THAT THE MAINS WATER SUPPLY MEETS THE REQUIREMENTS LISTED ON PAGE 3 BEFORE CONTINUING WITH INSTALLATION. WARNING: BEFORE CONNECTING THE PIPE WORK TO THE IL095, ENSURE THAT THE PIPE WORK IS FULLY FLUSHED OUT. Fitting the pipes • The unit should be connected directly to the main cold water supply. • We recommend that you use Ø15mm copper or stainless steel pipe for the inlet and outlet connections. • Use PTFE tape for making screw joints. Do not use a jointing compound.
MAKING THE ELECTRICAL CONNECTIONS WARNING: THIS WATER HEATER MUST BE EARTHED. The electrical installation must be in accordance with the current BS.7671 (IEE Wiring Regulations) and “Part P” of the Building Regulations and/or local regulations Wiring to the mains (Check the unit rating to see which applies) • • • A 40 amp 240V supply is required for the 9.5kW unit A 45 amp 240V supply is required for the 10.8kW unit A 50 amp 240V supply is required for the 12.0kW unit 9.
Ensuring the earth continuity • If the unit is fitted in a bathroom, to conform with the current BS.7671 (formally IEE regulations), the units earth continuity conductor must be effectively connected to ALL exposed metal parts of ALL other appliances in the room. COMMISSIONING YOUR IL095 CHECKING FOR LEAKS • Let the water run through the unit for a few seconds. Check that no pipe joints leak.
HOW TO USE YOUR IL095 WARNING: DO NOT USE THE UNIT IF YOU THINK IT MAY BE FROZEN, AS THIS COULD RESULT IN SERIOUS DAMAGE TO THE UNIT. WAIT UNTIL YOU ARE SURE THAT IT HAS COMPLETELY THAWED OUT BEFORE YOU SWITCH ON. Basin • Check that the power is switched on at the mains isolator switch. • Turn on the hot water tap FULLY. If you do not turn the tap on, you will find that the temperature of the water will vary. The hot water temperature will have been set using the service valve (diagram 5).
WHAT TO DO IF THINGS GO WRONG (1) SELF HELP If the unit is not working satisfactorily, make the following checks before calling out the installer. Any one of these adjustments could restore the performance.
WHAT TO DO IF THINGS GO WRONG (2) PROFESSIONAL SERVICE If the previous “Self Help” checks fail to restore the performance, you should seek professional help. The person who installed the shower is probably the best one to investigate and correct it and is certainly the person to contact if you have had a problem in the guarantee period. The following additional checklist is provided for the benefit of the qualified service person.
HOW YOUR IL095 WORKS Water comes in through the inlet, via a flow switch. The flow switch measures how much water is passing through the unit. If it detects more than the preset level of:2.7 litres/minute for the 9.5kW model and 3.3 litres/minute for the 10.8kW and 12.0kW models The units heating elements are switched on. This is shown by the neon light glowing. The water is heated instantly as it passes through the copper heat exchanger tube.
