1.0General Information

●This MYSON SLIM-LINE RC fan convector is designed for wall mounted installation with a minimum installation height of 150mm to the underside of the unit.

●The SLIM-LINE RC should only be used on closed circulation, two pipe, pump assisted central heating systems.

●The SLIM-LINE RC can be used on heat pump systems.

●The minimum side clearance is 100mm.

●The maximum ceiling height is 3m.

●Before proceeding with the installation, the heating system design must be considered and the unit correctly sized to meet the heat loss requirements of the room at normal fan speed.

●This unit is supplied with an infra red remote control system and can be operated in either automatic or manual mode. In automatic mode the desired room temperature is

programmed into the unit and the fan speed is automatically adjusted until the desired room temperature is achieved. In manual mode any of the 3 available fan speeds can be selected without automatic room temperature control. This feature can be used to circulate ambient air in summer, for example, or to provide manual control of heating performance.

●The appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety.

Children should be supervised to ensure that they do not play with the appliance.

This unit MUST NOT be installed in a bathroom or other similar high humidity area.

2.0 Heating System Design

This fan convector must be fitted on a two pipe, pumped circulation heating system.

For optimum fan convector heating performance the system must be capable of providing sufficient hot water through the heat exchanger. This means that:

1.The minimum pipe size from boiler to fan convector must be 15mm.

2.This unit is not suitable for use on microbore pipe-work.

3.Where the unit is fitted on to a system with other emitters a separate circuit for the fan convector should be considered to provide adequate water flow.

4.The system water must be above 43°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 balancing of the whole system.

8.This unit must not be used to replace a radiator in an existing system unless an adequate flow of water through the unit can be guaranteed.

3.0 Unit Selection/Sizing

Heat output performance is given in the Technical Data section of this manual. Outputs are shown for the three fan speeds, however, it is important to size the unit to match the calculated heat loss requirements of the room with the unit operating on the low fan speed. The higher fan speeds are used in automatic mode when the room temperature is significantly lower than the preset temperature.

When establishing the temperature difference, ie mean water to room temperature, allowance should be made for temperature drop in the system. It is the water temperature of the unit which dictates the output.

4.0Location

●This SLIM-LINE RC unit may be fitted to any convenient wall at a height from floor level that suits the application, providing an unimpeded flow of warm air into the area to be heated.

●The minimum distance from the underside of the unit to floor level is 150mm.

●The unit should be mounted on a flat wall, and stud or partition walls should be avoided to minimise the possibility of noise transmission.
