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
!CAUTION: The minimum clearance you should allow for proper ventilation around the
chamber must be at least 12" from both the left and right side, and 24" from
the rear.
!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.
!CAUTION: The Input Voltage label on the back of the chamber indicates the input voltage
configuration as shipped from the factory. If the input voltage configuration is
changed, this label must be replaced to reflect the new configuration.
Replacement labels are available from TestEquity at no charge.
!CAUTION: This chamber must be properly configured for either 208 V or 230 V nominal
input. 208 V and 230 V are NOT the same. Do NOT guess! Do NOT assume
you have “220 V”. You must verify the exact type of electrical service you
have. If there is any doubt, you must consult with a qualified electrician who
is familiar with industrial plant wiring. In addition, the input line voltage
should be measured while the chamber is operating in the COOL mode to
ensure that the expected nominal voltage of either 208 V –5/+10% or 230 V
±10% is present. Operation below 198 V or greater than 253 V requires
internal transformers, which can be supplied for a nominal charge.
2CAUTION: This chamber should be connected to the AC power source by a qualified
electrician who is familiar with industrial plant wiring.

Operation Safety Notices
!CAUTION: This chamber has a crankcase heater to protect the high-stage compressor. The
chamber must be connected to the power source AND the Main Disconnect
Switch must be ON for 3 hours prior to operating the chamber. Although it
may be safe to use the chamber immediately, this procedure ensures the
longest possible life for the high-stage compressor if the chamber has been
removed from the power source for more than 24 hours.
!CAUTION: The “Series F4 User’s Manual” is a general manual and is written by the
manufacturer, Watlow, for a wide variety of applications and configurations.
Not all features or functions are applicable. Only the capabilities of a model
F4SH-CKA0-01, as described on page A.7 of the “Series F4 User’s Manual”
are applicable. “Cascade Control” as described on page 3.6 of the “Series F4
User’s Manual” is not applicable in this configuration. The “Retransmit”
function is available as an option.
!CAUTION: The Series F4 “Alarm” functions are NOT used in the chamber’s safety
system and are NOT connected. TestEquity does NOT recommend using the
Series F4 alarm function as the main protection device. The independent
EZ-Zone Limit Controller functions as the main protection device.
!CAUTION: The Series F4 Temperature Controller has been properly configured by
TestEquity to match the chamber’s system requirements and to perform
optimally over a wide range of operating conditions. Improper modifications
to these setup values can result in erratic performance and unreliable
operation. Setup examples in the “Series F4 User’s Manual” are NOT
applicable to this chamber. Do not attempt to modify the setup values, unless
you thoroughly understand what you are doing. If there is any doubt, please
call TestEquity before proceeding.
!CAUTION: NEVER select “Full Defaults” in the Series F4 Controller’s Factory/Test
Menu. This will erase all the correct values which are documented in the
“Series F4 Temperature Controller Setup Parameters” section of this manual.
!CAUTION: The EZ-Zone Limit Controller has been properly configured by TestEquity to
match the chamber’s system requirements. Improper modifications to these
setup values can result in unreliable and unsafe operation. Do not attempt to
modify the setup values, unless you thoroughly understand what you are
doing. The correct values are documented in the “EZ-Zone Limit Controller
Setup Parameters” section of this manual.
!CAUTION: Always verify that the Limit Controller’s high and low limits are set to
temperatures that are appropriate for your test sample.

Chapter 1 – Safety
TestEquity 1007C Temperature Chamber Page 1-3
!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. This chamber has a set of contacts that can be used to remove power to
your test sample if the Limit Controller’s temperature limits are exceeded.
!CAUTION: To prevent damage to your test sample and the chamber’s compressors, do not
exceed the live load rating of the chamber.
!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.
!WARNING: Do NOT put items in the chamber which 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.

Chapter 2 – Installation
Page 2-2 TestEquity 1007C Temperature Chamber
Installation Location
The chamber will produce a significant amount of heat during normal operation. Locate the
chamber in a room with adequate ventilation to prevent excessive heat build-up.
The chamber must be on a solid and level floor. Leveling legs are provided to lock the chamber
securely in place if desired.
Allow enough space around the chamber to permit serviceability and the removal of the service
access panels, which are located on each side and the rear.
!CAUTION: The minimum clearance you should allow for proper ventilation around the
chamber must be at least 12" from both the left and right side, and 24" from
the rear.
!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.
Condensate Drain
The chamber has a condensate drain connection on the rear of the chamber. This provides a way
to remove condensate that may accumulate in the chamber during low-to-high 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, the ice or frost will turn into water.
The fitting accommodates a ½-inch male pipe thread. The chamber drain water is not under
pressure, and is fed by gravity. Therefore, it must empty into an 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).
