Power Supply Assembly. Warning! Electrical service must be properly configured for outdoor use with the correct voltage and frequency in accordance with local electrical codes. Consult a qualified electrician if unsure. E-FRM-DC-9800 REV A Page 23...
3.3.8 Dust Filter Removal and Installation The E-FRM-DC Sampler enclosure is cooled by drawing ambient air up through the bottom of the enclosure. This cool air passes over the internal components and is then exhausted out of the rear wall near the top of the enclosure. A cooling fan draws cool air up into the enclosure and forces the warm air out of the rear wall exhaust vent.
The sampler is configured for PM sampling by using an internal VSCC™ (Very-Sharp-Cut Cyclone, Met One Instruments part number BX-808) to further separate out and trap particles larger than 2.5 microns in size, while allowing smaller particles through to the sample filter. The particle performance of these cyclones closely matches that of the classic WINS Impactor, but with simpler maintenance requirements.
4.1 The User Interface – Touchscreen Display Functions The E-FRM-DC user interface is a touchscreen display used to control almost all the features and functionality of the sampler. It is mounted inside the enclosure and is only accessible when the front door of the E-FRM-DC is open.
