Chapter 1 – Safety Instructions
Introduction
Follow all CAUTION notices to prevent damage to the chamber or your test sample. Failure to
follow all CAUTION notices may void your warranty. CAUTION may also indicate a
potentially hazardous situation which, if not avoided, may result in minor or moderate personal
injury.
WARNING indicates a potentially hazardous situation which, if not avoided, could result in
death or serious injury.
The safety alert symbol !precedes a general CAUTION or WARNING statement.
The electrical hazard symbol 2precedes an electric shock hazard CAUTION or WARNING
statement.
Installation Safety Notices
2WARNING: The power cord is equipped with a NEMA 5-15P grounded/polarized plug. To
prevent a shock hazard, DO NOT defeat the ground or polarization feature.
This device MUST be plugged into a properly grounded and polarized outlet.
!CAUTION: The minimum clearance you should allow for proper ventilation must be at
least 12" from the rear of the chamber.
!CAUTION: This chamber is designed for operation in a conditioned laboratory
environment. Operation above 30°C (85°F) or below 16°C (60°F) ambient
room temperature is NOT recommended.
Operation Safety Notices
!CAUTION: The Temperature Controller’s “Alarm 1” function is NOT used in the
chamber’s safety system and is NOT connected. The independent EZ Zone
Limit Controller functions as the main protection device.
!CAUTION: The Temperature Controller’s “Alarm 2” is configured to lock the
refrigeration control system in “full cooling” mode at temperatures below
–35°C.This alarm setting must NOT be changed under any circumstances!
!CAUTION: Always verify that the EZ Zone Limit Controller settings for high and low
limits are set to temperatures that are appropriate for your test sample.
!WARNING: Do NOT put items in the chamber that could burn or explode at high
temperatures. This chamber uses open wire heating elements which generate
surface temperatures over 1000ºF. This is NOT an explosion-proof chamber.

Chapter 1 – Safety
Page 1-2 TestEquity 106 & 107 Temperature Chamber
!WARNING: Do NOT put items in the chamber that can emit corrosive vapors or
substances.
!WARNING: This chamber is NOT a curing oven. There are NO provisions for venting
fumes.
!WARNING: The chamber door must remain closed while the chamber is operating. If you
need to open the door while the chamber is operating, wear safety goggles to
prevent the high velocity airflow from blowing particles or objects into your
eyes.
!WARNING: This chamber operates at extreme temperatures. Avoid contact with air,
objects, and surfaces that are hot or cold to prevent severe burns or frostbite.
Protective gloves are recommended.
!CAUTION: If your test sample is energized, it may be capable of raising the workspace
temperature beyond safe limits. This could occur if your test sample exceeds
the live load rating of the chamber or if the chamber’s refrigeration system
fails. You are responsible for providing thermal protection devices to your test
sample.
!CAUTION: To prevent damage to your test sample and the chamber’s compressor, do not
exceed the live load rating of the chamber.

Chapter 2 – Installation
Unpacking
Inspect the shipping container for any signs of visible damage. Notify the carrier and TestEquity
immediately if there are signs of shipping damage.
1. Cut the bands that hold the packaging together.
2. Remove the top cover and top foam inserts.
3. Remove the outer box.
4. Carefully lift the chamber off the pallet. This should be done with at least two people.
Preparation For Use
1. Inspect the chamber for signs of shipping damage.
2. Read this entire manual.
3. Select a suitable location to install the chamber.
4. Hand-tighten one of the supplied barbed fittings to the drain connection on the rear of the
chamber. Put a container under the condensate drain. Alternatively, attach the supplied hose
to the barbed fitting and run the hose to a remote container, drain, or condensate pump.
NOTE: Not all applications will result in condensate flowing through the drain.
5. Connect to a 120 VAC, 60 Hz power source with a minimum 15 Amp breaker.
6. Perform following the procedure “How to verify the chamber performance” in the
Maintenance chapter of this manual to make sure that no damage has occurred in shipment.
Installation Location
The chamber will produce a moderate amount of heat during normal operation. Locate the
chamber in an area with adequate ventilation to prevent excessive heat build-up. The chamber
must be on a solid and level surface that is rated to hold at least 100 pounds.
2WARNING: The power cord is equipped with a NEMA 5-15P grounded/polarized plug. To
prevent a shock hazard, DO NOT defeat the ground or polarization feature.
This device MUST be plugged into a properly grounded and polarized outlet.
!CAUTION: The minimum clearance you should allow for proper ventilation must be at
least 12" from the rear of the chamber.
!CAUTION: This chamber is designed for operation in a conditioned laboratory
environment. Operation above 30°C (85°F) or below 16°C (60°F) ambient
room temperature is NOT recommended.

Page 2-2 TestEquity 106 & 107 Temperature Chamber
Condensate Drain
The condensate drain connection is located on the rear of the chamber. This provides a way to
remove condensate that may accumulate on the evaporator (cooling coil) during temperature
cycling or when the refrigeration system runs to maintain moderate temperatures.
Any time the ambient air is subjected to temperatures below the dew point, moisture will
condense out of the air. The effect is ice or frost during low temperature operation. When the
chamber is heated above 0°C or the cooling system turns off, the ice or frost will turn into water.
The drain fitting accommodates a 1/4-inch male pipe thread. Right angle and straight barbed
adapters are provided so you can easily connect 3/8-inch I.D. flexible tubing to it. The chamber
drain water is not under pressure and is fed by gravity. Therefore, it must empty into a container
or open floor drain. Alternatively, the chamber drain can empty into a condensate pump. You can
purchase a condensate pump from suppliers such as Grainger (www.grainger.com).
Under most circumstances, you will not see any water coming out of the drain.
Reversible Chamber Door (Model 107 only)
The chamber door can be mounted to open from the left or right side. The chamber cabinet has
mounting holes on both sides for the hinges and door latch. If you reverse the door, see “How to
inspect the door seal” in the Maintenance chapter of this manual to make sure the hinges and
door latch are adjusted correctly.

Chapter 3 – Operation
Introduction
The Front Panel Switches control power to the temperature controller and all chamber functions.
The Temperature Controller controls the temperature of the chamber. The Temperature
Controller automatically turns the refrigeration system on or off as required based on the
deviation from temperature set point.
Refer to the separate F4 or F4T Temperature Controller manual for details on how to use the
Temperature Controller.
Summary of Chamber Operation
1. Turn the POWER Switch ON.
2. Enter the desired temperature set point on the Temperature Controller.
3. Load your test sample in the chamber.
4. Turn the TEMP Switch ON. Alternatively, turn the TEMP Switch to the EVENT 1 position
and turn EVENT 1 on the F4 controller or the Power button on the F4T controller ON.
Front Panel Switches
POWER Switch
The POWER Switch controls power to the entire chamber. The POWER Switch illuminates
when it is ON.
TEMP Switch – ON Mode
The TEMP Switch enables all chamber functions. When the TEMP Switch is OFF and the Power
Switch is ON, only the Temperature Controller and Limit Controller are operational. When both
the TEMP and POWER Switches are ON, the chamber’s temperature conditioning system will
function to maintain the temperature set point. The TEMP Switch does not illuminate.
TEMP Switch – EVENT 1 Mode
When the TEMP Switch is in the EVENT 1 position, you can enable and disable all chamber
functions through Event 1 (Digital Output 1) of the F4 Temperature Controller or the Power
button on the F4T Temperature Controller.
