TestEquity TEC1 Thermoelectric Temperature Chamber
Condensate Drain
Any time the ambient air is subjected to temperatures below the dew point, moisture will
condense out of the air.
Example 1:
If the room temperature is 23°C (74°F) and the humidity is
≥
45%RH, moisture will
condense if the chamber is held at 10°C (51°F).
Example 2:
If the room temperature is 23°C (74°F) and the room humidity is ≥59%RH,
moisture will condense if the chamber is held at 15°C (58°F).
The condensate drain connection is located on the rear of the chamber. The chamber drain water
is not under pressure and is fed by gravity. Therefore, it must empty into a container. The drain
fitting accommodates a 3/8-inch ID hose.
Under most controlled laboratory or office conditions, there will be no condensation and the
Condensate Drain can be ignored.
Input Voltage Configuration
(Does not apply to model TEC1-001, which is only rated for 115V input)
This chamber can be configured for 115V (88 to 132VAC) or 230 V (176 to 264VAC), 50/60 Hz
input. The chamber ships pre-configured for the correct input voltage based on the county it
ships to. To change the input voltage, use the following procedure:
1.
Make sure the chamber is NOT plugged into the power source.
2.
Remove the 6 screws on the perimeter of the right side panel.
3.
Locate the red voltage selection switch on the DC power supply on the side which normally
faces up.
4.
Select either 115 V or 230 V as applicable.
5.
Reattach the right side panel, ensuring that no wires are pinched.
6.
Plug the chamber into the power source.
7.
Turn the POWER switch ON.
8.
On the Temperature Controller, enter the Setup Menu\Global Menu. Change the AC Line
Frequency (AC.FL prompt) to either 50 or 60 (Hz) as appropriate. See EZ-Zone Temperature
Controller Setup Parameters in Chapter 7 for instructions on how to navigate to this menu.
