Switch off the power at the isolation switch and ensure the unit has stopped operating for at least five minutes to avoid run-on time. Use a square key to open locked doors.
Filters should be checked for contamination, damage, and odours, and changed if necessary. Pressure loss should also be checked and filters replaced if needed.
Switch off the power, inspect for dust and shavings, then use a compressed air gun to clean the rotor from the outdoor air side to the supply side while manually rotating it. Vacuum up any debris blown through.
