SLIM-LINE RC
1.0 General Information
2.0 Heating System Design
GThis MYSON SLIM-LINE RC fan convector is designed for wall
mounted installation with a minimum installation height of
6" to the underside of the unit.
GThe SLIM-LINE RC should only be used on closed circulation,
two pipe, pump assisted central heating systems, or as a
stand alone zone.
GThe SLIM-LINE RC can be used on heat pump systems, for
heating only.
GThe minimum side clearance is 4".
GBefore 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.
GIn rooms with ceiling heights above 10ft a ceiling fan or other
means of heating stratification should be considered.
GThis 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.
This fan convector can be fitted on a series loop with mono-flo
or venturi Tees, on a two pipe system or as a stand alone zone.
For optimum fan convector heating performance the system
must be capable of providing sufficient hot water through the
heat exchanger. This means that:
1. Care must be taken in sizing both the pump and piping.
2. The minimum pipe size from boiler to fan convector must be
at least 1/2".
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 110°F for heating mode.
5. Optimum performance of this unit will require effective
balancing of the whole system.
6. This unit should NOT be used to replace a radiator in an
existing system unless an adequate flow of water can be
guaranteed through the unit.
7. The loop must be pumped. HI-LINE fan convectors are not
suitable for gravity circulation systems.
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, i.e. entering
water to room temperature, allowance should be made for
temperature drop in the system. It is the water temperature at
the unit which dictates the output.
4.0 Location
GThis 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.
GThe minimum distance from the underside of the unit to floor
level is 6".
GThe unit should be mounted on a flat wall, and stud or
partition walls should be avoided to minimise the possibility
of noise transmission.

7.0 Water Connections
GConnect unit to system flow and return pipes using the two
5/8" isolating valves (see fig. 2).
GEnsure system is flushed in accordance with recognised best
practice and a suitable inhibitor is added to the system as
necessary.
GOpen valves fully, check pipe connections for leaks and vent
the heat exchanger - see Commissioning Procedure.
Note: To ensure effective venting of the heat exchanger the flow
pipe should be connected to the bottom connection of the heat
exchanger.
Note: For SLIM-LINE RC installations pipe-work must not be
routed directly underneath the unit as this will adversely affect
the operation of the integral room thermostat. If this cannot be
avoided, the pipe-work must be boxed to prevent heat rise.

SLIM-LINE RC
11.0 Operating Instructions
Description
This SLIM-LINE RC unit is fitted with a control system that
provides either automatic or manual control of the unit. In
automatic mode the desired temperature set point is selected
and the unit will adjust the fan speed according to the difference
between the actual room temperature and the set point. When
the room temperature reaches the set point the fan will switch
off and thereafter will continue to cycle on and off to maintain
the room temperature. The temperature set point range is
59 - 95°F.
In manual mode the automatic temperature control is
overridden and any of the three fan speeds can be operated
inrespective of the water temperature in the unit. This means
that air circulation can be provided in summer for example, or
that heating performance can be controlled manually.
The unit can be controlled using the infra red remote control
handset supplied with the unit (see fig. 4) and also using
the control panel on the unit (see fig. 5). If necessary, however,
the control panel can be locked electronically to prevent
tampering once the controls have been set (see over).
The remote control hand set takes 2 AAA batteries (not supplied).
