Tec Module - Micromeritics ACCUPYC II 1345 Series Installation Instructions And Checklist

2 Equipment Installation
TEC M
ODULE
This AccuPyc system has been modified to provide temperature control from 15 to 36 °C. The
system uses a thermoelectric control (TEC) system to heat or cool the AccuPyc. The temperature is
controlled using a digital temperature controller and a separate power system from the AccuPyc.
It is suggested that the TEC system be installed first, to allow time for temperature to stabilize at the
desired temperature, while the AccuPyc is being installed.
Set the TEC Temperature
1. Power on the TEC module. The power switch is located near the power inlet.
The digital display of the temperature controller will show a test message while it starts up.
When the test message stops flashing, the current temperature displays. If the current
temperature and a message such as ErAt displays, press the P (Program) key on the front
panel of the controller. The ErAt message should stop and only the current temperature will
display.
2. Press P. SP 1 displays followed by the current setpoint (SP 1). Use the Up or Down key to
set the temperature.
3. Press P to accept the temperature. The controller will now start heating or cooling to achieve
the setpoint
The TEC module uses a fan to remove heat. The fan is located on the underside of the
instrument. The fan pulls air into the instrument and the air is exhausted through
ventilation slots on the rear panel. The exhaust slots must remain unobstructed.
Do not allow papers or other debris to be pulled across the fan as this will stop the
necessary air flow. The TEC system will be unable to control temperature, and may
become damaged.
