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.
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 F4T/F4 Controller alarms are configured for internal protection of the
humidity system. Do NOT change this configuration under any circumstances.
The independent EZ-Zone Limit Controller functions as the main system and
product protection device.
!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.
!CAUTION: If your test sample is energized, it can raise 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 or volatile substances.

TestEquity 1016H & 1027H Temperature/Humidity Chamber Page 1-3
!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
Uncrating
Inspect the shipping container for any signs of visible damage. Notify the carrier and TestEquity
immediately if there are signs of shipping damage.
The pallet is designed with ramps, so the chamber can be rolled off without the need for a forklift
or pallet jack.
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. Verify the input voltage configuration.
5. Connect to the power source.
6. Perform following the procedures as described in the Preventive Maintenance section:
a. Inspect the electrical compartment.
b. Inspect the refrigeration machinery compartment.
c. Check the low-stage refrigeration charge.
e. Verify the chamber performance.
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
generates a heat load of up to 27,500 BTUH during a continuous cool down from a high
temperature.
The chamber must be on a solid and level floor. 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.

Input Power Configuration
Overview
This chamber can be easily configured for operation from a 208 V / 60 Hz or 230 V / 60 Hz,
3 Phase nominal input. Other input voltages and 50 Hz operation are available as special options,
and are not covered in these instructions.
Your chamber was configured prior to shipment for the voltage that was specified at time of
order. These instructions should be used to verify the input voltage configuration prior to
installation, or to change the input voltage from one configuration to another.
!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 a continuous HEAT
mode to ensure that the expected nominal voltage of either 208 V –5/+10% or
230 V ±10% is present.
