Installation Precautions
y Leave at least 500mm surround the air outlet.
y Ensure that the air inlet will not take any hot gas from the air outlet.
y When Qumi is used in a confined space, ensure that the ambient temperature will not
exceed the working temperature of Qumi and the air inlet and outlet are unclogged.
y Every confined space should pass through professional thermal evaluation to avoid
circulation during Qumi exhaust. Otherwise, even when the confined space temperature is
within the acceptable working temperature range, the machine may also shut down.
Caution:
Avoid usage of Qumi in dusty environment.
