Exhaust System
Do not put the foreline pump(s) in an enclosed space. Foreline pumps exhaust most
compounds introduced into the MS and small amounts of oil vapor.
Provide an adequate fume exhaust system for the outlet of each foreline vacuum pump. Each
foreline pump must be vented at least 2 L/min. The API spray chamber must be vented at least
12 L/min to a separate vent line. Ensure that the exhaust system does not pull a vacuum on the
API chamber. Consult local regulations for the proper method of exhausting the fumes.

Check the checklist box: Exhaust system is suitable.
Temperature
The optimal operating temperature is between 16 and 30 °C (61-86 °F).
NOTE: As installation site temperature increases, system reliability decreases due to heat
generated by electronic components during operation. This heat must dissipate to the
surrounding air for reliable operation.
The airflow around the system must be adequate. The air-conditioning system must maintain a
constant temperature (within the operational limits) around the system. Do not place the system
near air ducts, windows, or heating and cooling systems. The average steady-state heat load
for the MS alone is 6,000 Btu, with a possible short-term heat dissipation of 15,000 Btu during
startup.
