Installation - Ametek 600 Series Instruction Manual

Installation

TO COMPLY WITH HAZARDOUS AREA STANDARDS, UNIT MUST BE INSTALLED IN A MINIMUM IP54
ENCLOSURE AND PROTECTED FROM DUST/ WATER INGRESS. ADEQUATE VENTILATION MUST BE
PROVIDED FOR DISSIPATION OF A MINIMUM OF 1200 BTU/hr (1265 kJ/hr)
Universal Analyzers 600 Series Mini Thermoelectric Gas Cooler should be installed away from heat sources in a well
ventilated area of an instrument rack or enclosure. The Cooler relies on the ambient temperature as a coolant, too high
a level will cause it to perform unreliably. Contact the factory for recommendations. Air purging an enclosure does not
provide enough ventilation to remove the heat which will be generated internally by the sample chiller. On the other hand,
there are air conditioners and vortex coolers which can provide the necessary cooling for enclosing thermoelectric chillers.
The 600 Series Mini Cooler has mounting taps on the top and bottom to allow it to be wall mounted or mounted to rails in
an instrument rack. Accessories mounted on the side can be supported by the mounting flange on the cooler.
A 3/8" tubing fitting is provided at the top of the heat exchanger as the sample inlet. The dry sample outlet from the cooler
is the 1/4" Kynar tube fitting exiting out of the top of the heat exchanger at an angle. The gas sample should be further
conditioned with an additional filter as a safety measure before it enters the analyzer(s). The WCOF visible filter which
incorporates a safety moisture sensor is designed for this purpose. A similar filter without the moisture sensor is also
available from Universal Analyzers. A separate moisture sensor, the WCO, can also be provided where the user prefers
that form factor. Contact the factory for information, pricing, and drawings.
A sample pump is normally required to pull the sample through the sample cooler and to force it through the visible filter.
The moisture sensor, if not a part of the visible filter should be located ahead of the visible filter. There must be a method
to remove the condensate from the heat exchanger. Accessories available from Universal Analyzers include a peristaltic
pump, eductor, or drain pot, which must be run to sewer, a container, or other drain that heads out of the instrument
enclosure, to avoid collecting water (condensate) on the floor.
If an eductor is utilized to remove the condensate, the outlet tube length should be no longer than two feet in order to
maintain low back pressure at the outlet of the eductor. The outlet tube can be placed in a larger pipe to channel the
condensate to a drain.
An external power supply must be used with the 600 series chiller. See the table below for power supply wattage
recommendations. Installation shall be in accord with the manufacturer's instructions and the National Electrical Code
(ANSI/NFPA 70). Tampering and replacement with non-factory components may adversely affect the safe use of the
system. See the wiring diagram in drawing P0327. The alarm relay has two sets of dry contact alarms at TB2 and TB3.
One set is typically used to control the power to the sample pump (when wired as shown in P0327, power is only provided
to the pump when the cooler is not in an alarm state).

NOTE: THE SUPPLY POWER CIRCUIT MUST INCLUDE AN OVERPROTECTION DEVICE WITH A
MAXIMUM RATING OF 20 A. A DISCONNECT SWITCH MUST BE LOCATED IN CLOSE PROXIMITY TO
THE COOLER. IF THE EQUIPMENT IS USED IN A MANNER NOT SPECIFIED BY THE MANUFACTURER,
THE PROTECTION PROVIDED BY THE EQUIPMENT MAY BE IMPAIRED PER CLAUSE 5.4.4(I) IN
STANDARD EN 61010-1.
THE MOISTURE SENSOR CAN BE CONNECTED TO THE "VIKING" CONNECTOR MOUNTED ON THE
EXTERIOR OF THE ENCLOSURE NEXT TO THE HEAT EXCHANGERS.
