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 5-20P grounded/polarized plug. To
prevent a shock hazard, DO NOT defeat the ground or polarization feature.
This device MUST be plugged DIRECTLY into a properly grounded and
polarized NEMA 5-20R receptacle. Due to high current demand on start-up,
use of an extension cord is NOT recommended.
!CAUTION: The minimum clearance you should allow for proper ventilation around the
chamber must be at least 6" from both the left and right side, and 12" 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.

Operation Safety Notices
!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
F4DH-CKCC-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 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 Series F4 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 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.
!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.
