You can push filament through, with the lever open, until you see it coming
out of the nozzle (assuming the hotend is heated to the correct temperature).

The filament is now loaded.
Lid/Chamber Exhaust Fan
A 24VDC 60mmx10mm slim fan is included on the lid of the printer. This fan
is set to exhaust excess heat from the chamber when the heated bed is at or
above 85C at 10% power. The fan is thermostatically controlled from the
motherboard, this means it will automatically turn on at a minimum 85C heated
bed temperature at 10% fan power. During stress testing, we found that longer
prints would generate excess heat at the top of the chamber and stress the acrylic
lid causing it to bow and flex. While we want to keep heat in the printer, we do
not need excess heat causing warped acrylic and heat soaking the motors. This
fan will allow the hot air to stay in and exhaust excess heat to protect the internal
components of the printer. This fan can be disabled under the Fan section of Duet
Web Control browser interface via a computer if the customer would choose to,
however we do not recommend it.
