4. Electric installation
All electrical installations and the installation and connection of the thermostats in the separate
electric centre shall be left to an authorised electrician!
Instructions for installation of the thermostats intended for the electrician:
- The temperature regulator (LTM thermostat) is installed in the air pipe at maximum at 2.0 m
distance from the heater in an opening which is made at the average height of pipe or above it.
The electric conductors shall be at at least 50 mm distance from the surface of the heating pipe
to avoid risk of overheating.
- Make sure that the LTM-thermostat is adjusted so that the drying temperature (limit) cannot ex-
ceed 80°C. The thermostat in question also prevents the stopping of the fans until the drying air
temperature has dropped to 45°C.
- The temperature limiter LTS-thermostat with manual reset button (not compulsory in Finland) is
installed in the same way as LTM.
- The LTS-thermostat is adjusted to (limit) 100°C. It switches off the heater as soon as the drying
air temperature rises to 100°C. The thermostat requires manual resetting before the operations
of the heater can be restored.
- Due to the thermal radiation emitted by the heater, the LTM and LTS thermostats may trip at a
lower temperature which does not correspond the actual temperature in the pipe. Because of
this verify the real temperature of the drying air in the pipe and readjust the settings of the thermo-
stats accordingly. (In practice this can mean that the limit at 80°C must be readjusted to 95°C
although the real air temperature in the pipe is 80°C ).
Initial settings:
LTM fan 45°C and limit 80°C
LTS fan - no connection and limit 100°C (this thermostat is not required in Finland)
- The 2-effect thermostat or the PTC-100 probe of the 2-effect thermostat (in digital centres) is
installed farther away in the air piping. The electrification of the heater is carried out in accor-
dance with the wiring diagrams of the electric centre. If anything is unclear, please contact the
factory.
- If the heater is connected with the automation centre, see also the connection instructions for the
automation.
