LO-LINE RC & LO-LINE RC Heater/Cooler
03
l This MYSON LO-LINE fan convector is designed for wall
mounted installation with a minimum installation height of
6 inches to the underside of the unit.
l The LO-LINE should only be used on closed circulation, two
pipe, pump assisted central heating systems (LO-LINE), on
heating and cooling systems (LO-LINE Heater/Cooler), or as a
stand alone zone.
l The LO-LINE Heater and Heater/Cooler can be used on low
water temperature systems.
l The minimum side clearance is 4 inches.
l In rooms with ceiling heights above 10ft a ceiling fan or other
means of heating stratification should be considered.
l 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.
2.0 Heating System Design
This fan convector can be fitted on a series loop with mono-flo
or venturi Tees, on a two pipe system, or on 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 the piping.
2. The minimum pipe size from boiler to fan convector must be
1
/2inch copper tube.
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.
l This unit is supplied with an infra red remote control system
and has 3 operating modes:
Automatic – the desired room temperature is programmed in
to the unit and the fan speed is automatically adjusted until
the desired room temperature is achieved.
Fan only – allows user selection of any of the 3 available
fan speeds irrespective of room temperature or water
temperature in the coil.
Fan only with water temperature control – allows the user to
select any of the available fan speeds, which will operate only
if the water temperature in the coil is above 90°F. This enables
control of the unit via an externally mounted room thermostat
if desired.
4. The system water must be above 90°F for heating mode.
5. Optimum performance of this unit will require effective
balancing of the whole system.
6. 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.
7. The loop must be pumped. LO-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 normal fan speed. The higher fan speeds are used in
automatic mode when the room temperature is significantly
lower than the preset temperature.
4.0 Location
l This LO-LINE 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.
l The minimum distance from the underside of the unit to floor
level is 6 inches.
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 that dictates the output.
l Prior to installation the wall should be checked to make sure
it is straight and flat, to avoid twisting the unit.
l For cooling applications, the need for disposal of condensate
may influence the position of the unit.

5.0 Preparation
Before proceeding with the installation, unpack the carton
contents and check against the checklist below:
1. LO-LINE or LO-LINE Heater/Cooler unit.
1
2.
/2inch isolating valves (1 pair).
3. Instruction manual.
4. Fixing kit (rubber mounts and cable gland).
5. Remote control handset.
6.0 Fixing
l Using the fixing dimensions (see fig. 1), mark the fixing hole
positions on the wall.
l Plastic or metal anchors suitable for No.8 wood screws should
be used for mounting the convector to the wall.
l Remove the backing from the self-adhesive washers and place
on screws with adhesive side towards the point.
Fig. 1
l Tighten the screws into the wall leaving about
projecting.
l Press adhesive washers to the wall.
