Description and use
The “Pre-Heating Box” unit is an electrical heater to
be fitted to the cold air inlet duct upstream of the heat
exchanger. It is intended to resolve the problem of
frost formation on the heat exchanger, caused by the
combination of the low temperatures of external air
and the high levels of moisture in the air in the areas
being treated.
The connection box at the top of the body provides
access to the electrical wiring terminals, and also
contains two thermostats, an auto-reset safety
thermostat calibrated at 55°C (± 10%), and manual
reset thermostat calibrated at 70°C ± 10%.
