8 Mexico Super 100 FF & 125 FF - InstallationGENERALWATER TREATMENTThe Mexico Super FF incorporates a cast iron heat exchanger.As part of the installation the central heating system should bethoroughly flushed with appropriate water treatment in order tocomply with BS7593:1992Caradon Plumbing Limited recommend the use of Fernox orBetz Dearborn water treatment products which must be used inaccordance with the manufacturers instructions. For furtherinformation contact :-Fernox Manufacturing. Co. Ltd., Tandem House, MarloweWay, Croydon, Surrey CRO 4XS, tel 0870 5601 5000orBetz Dearborn Ltd., Widnes, Cheshire, tel. 0151 424 5351IMPORTANT.ANY OTHER TREATMENT FOR THIS PRODUCT WILLRENDER THE GUARANTEE OF CARADON PLUMBINGLIMITED INVALID.Notes.1. If an inhibitor is used, and in hard water areas wheretreatment to prevent lime deposits is necessary, it is mostimportant that the water treatment MUST be maintained atthe correct concentrations recommended by the treatmentmanufacturer.2. Artificially softened water must not be used in the system,under any circumstances.THERMOSTATIC RADIATOR VALVESCaradon Plumbing Limited recommend that heating systemsutilising full thermostatic radiator valve control of temperature inindividual rooms should also be fitted with a room thermostatcontrolling the temperature in a space served by radiators notfitted with such a valve, as stated in BS. 5449.When thermostatic radiator valves are used, the space heatingtemperature control over a living / dining area or hallway havinga heating requirement of at least 10% of the boiler heat outputshould be achieved using a room thermostat, whilst otherrooms are individually controlled by thermostatic radiatorvalves. However, if the system employs thermostatic radiatorvalves on all radiators or two port valves without end switchesthen a bypass must be fitted in order to ensure a flow of watershould all the valves be in the closed position.ELECTRICAL SUPPLYWARNING. The appliance MUST be efficiently earthed.Wiring external to the appliance MUST be in accordance withthe current I.E.E. (BS 7671) Wiring Regulations and any localregulations which apply.The boiler is supplied for 230 V ~ 50 Hz single phase. Thefuse rating is 3A.Connection must be made in a way that allows completeisolation of the electrical supply - such as a double pole switch,having a 3mm ( 1/8 ") contact separation in both poles, or a plugand socket serving only the boiler and system controls.The means of isolation must be accessible to the user afterinstallation.For bathroom installations the point of connection to the mainsmust be situated outside the bathroom.WATER CIRCULATION SYSTEMThe boiler must NOT be used for direct hot water supply or forsealed systems. The boiler is suitable for connection topumped open vent central heating systems, pumped centralheating combined with pumped or gravity indirect domestic hotwater supply systems.The boiler is NOT suitable for gravity heating systems. Thehydraulic resistances of the boilers at maximum output with11 oC (20 oF) temperature differentials are shown in the graphbelow.The central heating system should be in accordance withBS. 6798 and, in addition, for smallbore and microboresystems, BS. 5449:1.The domestic hot water system, if applicable, should be inaccordance with the relevant recommendations of BS. 5546.Copper tubing to BS. 2871:1 is recommended for watercarrying pipework.The hot water storage cylinder MUST be of the indirect typeand should preferably be manufactured of copper.Single feed, indirect cylinders are not recommended andMUST NOT be used on sealed systems.The hot water cylinder and ancillary pipework not forming partof the useful heating surface should be lagged to prevent heatloss and any possible freezing - particularly where pipes runthrough roof spaces and ventilated underfloor spaces.IMPORTANT.The boiler must be vented. If venting cannot be done via a flowconnection a separate vent MUST be fitted by the installer.Draining taps MUST be located in accessible positions, whichpermit the draining of the whole system - including the boilerand hot water storage vessel. They should be at least 1/2" BSPnominal size and be in accordance with BS. 2879.If required, a drain tap (not supplied) may be fitted to anunused bottom (1" BSP) tapping on the front of the boiler.Dotted lines indicate flow rates equivalent to atemperature rise of 11 o C (20 o F)Water Flow Rate and Pressure Loss
