RPS - June 2007 - Edition 12
Anatel Operator Manual
2.3.1.1 C80 Controller
The C80 Controller can be positioned wherever it is convenient. The stand-alone unit is desk-
mounted or wall-mounted in an aluminum enclosure that is sealed against moisture and is
splash-resistant. The wall-mount Controller is secured in place with a steel mounting bracket.
A 3/4" nut clamp accommodates the adjustable panel thickness, which can range in depth from
1/8" to 1/2" (3.17 mm to 12.70 mm). Controller mounting dimensions are shown below.
2.3.1.2 Anatel A643a–S Analyzer
The Anatel A643a–S Analyzer is a wall-mount unit. The standard instrument and Controller are
NEMA 12-compliant. They are splash-resistant but not waterproof and therefore should be
installed in a dry and relatively dust-free environment (an optional NEMA 4 case is available).
The air is filtered through an intake located on the bottom of the Analyzer. Do not allow the air
flow through the intake or outlet filters on the bottom of the instrument to be obstructed or to get
wet. If mounting the Anatel A643a–S outside, place it inside a water-tight enclosure and away
from direct sunlight. Ambient air temperature should not exceed 40 °C (104 °F) and venting the
enclosure may be necessary.
Do not expose the Anatel A643a Analyzer to a caustic atmosphere, as may be present in a DI
regeneration area or near an acid waste sump; exposure will corrode electronic circuitry and
damage analysis components. If an Analyzer must be installed in a hazardous area, it must be
protected by a suitable enclosure which complies with all instrument operating specifications
(see “Specifications and Accessories” on page 191).
