Several fans, including those in the power supply subassemblies, provide internal cooling for the MS. Cooling air enters through the three main air intake fans on the right side of the MS. Exhaust air exits the instrument from the back ventilation slots.
To ensure proper performance of the cooling system, maintain at least 10 inches of air space between the laboratory wall or other obstructions for the air intake fans on the right side of the MS and the ventilation slots on the back of the MS.
The only user-serviceable part of this cooling system is the air filter behind the front panel and in front of the air intake fans. For the recommended maintenance schedule, see "Clean the air filter".
CAUTION
To ensure safety and proper cooling, always operate the MS with its covers in place. This is also necessary to comply with product safety and electromagnetic interference regulations.
