03HI-LINE RC & HI-LINE RC Heater/Cooler1.0 General Information2.0 Heating System Designl This MYSON HI-LINE RC fan convector is designed forwall-mounted installation with a maximum installation heightof 2.13m to the underside of the unit.l The minimum installation height is 1.8m to the underside ofthe unit.l The minimum clearance between the top of the unit and theceiling should be 50mm.l The minimum side clearance is 100mm.l The HI-LINE RC should only be used on closed circulation,two pipe, pump assisted central heating systems (HI-LINE) orheating and cooling systems (HI-LINE Heater/Cooler).l Before proceeding with the installation, the heating systemdesign must be considered and the unit correctly sized tomeet the heat loss requirements of the room at normal fanspeed.l This unit is supplied with an infra red remote control systemand has 3 operating modes -Automatic – the desired room temperature is programmed into the unit and the fan speed is automatically adjusted untilthe desired room temperature is achieved.Fan only – allows user selection of any of the 3 availablefan speeds irrespective of room temperature or watertemperature in the coil.Fan only with water temperature control – allows the user toselect any of the available fan speeds, which will operate onlyif the water temperature in the coil is above 32C. This enablescontrol of the unit via an externally mounted room thermostatif desired.l The appliance is not intended for use by persons (includingchildren) with reduced physical, sensory or mental capabilities,or lack of experience and knowledge, unless they have beengiven supervision or instruction concerning use of theappliance by a person responsible for their safety.Children should be supervised to ensure that they do not playwith the appliance.This fan convector must be fitted on a two pipe, pumpedcirculation heating system.For optimum fan convector heating performance the systemmust be capable of providing sufficient hot water through theheat exchanger. This means that:1. The minimum pipe size from boiler to fan convector mustbe 15mm.2. This unit is not suitable for use on microbore pipework.3. Where the unit is fitted on to a system with other emitters aseparate circuit for the fan convector should be consideredto provide adequate water flow.4. The system water must be above 32°C for heating mode.5. For heat pump applications - see Commissioning Procedure.6. This unit is NOT suitable for one-pipe systems.7. Optimum performance will require effective balancingof the whole system.8. This unit should NOT be used to replace a radiator in anexisting system unless an adequate flow of water can beguaranteed.3.0 Unit Selection/Sizing4.0 Locationl This HI-LINE RC unit may be fitted to any convenient wall ata height from floor level that suits the application, providingan unimpeded flow of warm air into the area to be heated.l The maximum distance from the underside of the unit to floorlevel is 2.13m.l The minimum distance to the underside of the unit is 1.8m.l This unit should not be installed in locations with ceilingheights greater than 3m.l The unit should be mounted on a flat wall, and stud orpartition walls should be avoided to minimise the possibilityof noise transmission.l For cooling applications, the need for disposal of condensatemay influence the position of the unit.1.02.03.04.0This unit MUST NOT be installed in a bathroom or other similar high humidity area.Heat output performance is given in the Technical Data sectionof this manual. Outputs are shown for the 3 fan speeds,however, it is important to size the unit to match the calculatedheat loss requirements of the room with the unit operating onthe low fan speed. The higher fan speeds are used in automaticmode when the room temperature is significantly lower than thepreset temperature.When establishing the temperature difference, ie mean water toroom temperature, allowance should be made for temperaturedrop in the system. It is the water temperature at the unit whichdictates the output.
