2.1.6 CHAMBER PRESSURE
When optional exhaust is supplied to the chamber it should be maintained at an
operational negative pressure of
≥
0.5 inches (5.08mm) of H
O. Actual exhaust
flow which provides optimal processing results is user defined. The exhaust flow
can be controlled by our optional down flow exhaust adapter.
2.1.7 DISPENSE LIQUIDS
Automatic or manual syringe (optional)
2.1.8 EXHAUST REQUIREMENTS
The spin processor is intended for use in an exhausted bench area. The end
user is responsible for providing exhaust for the bench area.

2.1.9 VACUUM PUMP (OPTION)
LTC provided oil-less vacuum pump:
25 – 28” (635 – 711mm) Hg with a flow volume of 4.5 scfm (0.11cm/m ) @
0”Hg
Power - 100 – 115 or 220 – 230 VAC - 50 / 60 Hz.
It is recommended to install the pump in an open and well ventilated area.
Normal operating temperature after 1 hour of use is 75 ± 5°C (165 ± 9°F).
Pump is design for continuous use. The factory thermal protection
interlock is sensed on the motor windings and set for 135 ± 5°C (275 ±
9°F). The thermal reset temperature is 61 ± 9°C (142 ± 16°F).
Caution:
Pump will be hot after continuous use. Allow time for cooling before
handling pump.

2.1.10 SECONDARY CONTAINMENT AND SPILL PREVENTION FEATURES
When installed at the end-user site, secondary containment is recommended. It
should provide for the spin processor and the pressurized tank(s). All secondary
containment should incorporate appropriate gas detection, liquid sensors, and
alarms. If incompatible materials are used in the spin processor, (not
