OPTIONS
Sample Pump
The TEC1 series chiller is equipped with a dry contact relay that is capable of controlling a sample pump at a
maximum capacity of 10A @ 115/230VAC or less. The sample pump is supplied by others.
Water Slip Sensor
The TEC1 series chiller is equipped with one condensate slip input as standard, and will have a second installed
if there are 2 active channels.
The LS flow chamber is compact and without filter; while the Universal Filter allows the installation of filter
elements of various materials such as PTFE, Ceramic, Glass Fiber or 316SS. The available filters may be
selected by suitable material compatibility and porosity for the user’s specific application. Please refer to the
M&C datasheet titled “Universal Filter Series FP, FT” for specific part numbers.
START UP
Before using the equipment for the first time, check that the safety measures specific to the installation and
process are complied with.
It is important that the heated probe and heated sample line should be at operating temperature
before starting the chiller and sample pump.
The automatic control electronics of the TEC1 permit automatic start-up of the cooler. The error diagnostics
guarantee full monitoring and reporting of possible sources of error.
The following description is valid for start-up of the gas cooler for an ambient temperature > 8°C.
The following steps should be carried out before initial start-up:
1) Connect the cooler unit to the main power supply;
2) Connect the status contacts for reporting any alarm condition to the measuring station;
3) The sample pump dry contacts must be connected to the external sample gas pump or to a valve in the
sample gas line to protect the entire analysis system by immediately cutting off the gas supply in the event of
error messages from the cooler.
After power is applied, the indicated temperature will start to drop from ambient values immediately. It
should be below the over-temperature alarm point in approximately 5 minutes. Once the temperature is
below the over-temperature alarm point, both the alarm and pump control relays should energize.
