• DO NOT place the Nº433 on a thick rug or carpet or cover the
Nº433 with a cloth, as this might prevent proper cooling. If the
Nº433 is placed on the floor, use a thick piece of tempered glass
to provide firm support and proper ventilation.
• DO NOT expose the Nº433 to high temperatures, humidity,
steam, smoke, dampness or excessive dust. Avoid installing the
Nº433 near radiators or other heat-producing appliances.
Note In general, better ventilation is required if the top of the Nº433 is
hot to the touch when the power amplifier is “idle.” Open
equipment racks provide the best ventilation for power amplifiers.
However, if the power amplifier must be placed in a cabinet that
restricts airflow, consider drilling holes in the shelf underneath the
power amplifier to improve ventilation or using fans to increase air
circulation.
