I. Important Safety Information
SAFETY INSTRUCTIONS
The equipment described in this Manual is designed and manufactured to operate within defined design limits. Any misuse may result in electric shock or fire. To prevent the equipment from being damaged, the following rules should be observed for installation, use and maintenance. Read the following safety instructions before operating the instrument.
POWER
POWER CORD: Use only the power cord specified for this equipment and certified for the country of use. If the
power (mains) plug is replaced, follow the wiring connections specified for the country of use. When installing or removing the power plug, hold the plug, not the cord.
The power cord provided is equipped with a 3-prong grounded plug (a plug with a third grounding pin). This is both a safety feature to avoid electrical shock and a requirement for correct equipment operation. If the outlet to be used does not accommodate the 3-prong plug, either change the outlet or use a grounding adapter.
FUSES: Replace fuses only with those having the required current rating, voltage and specified type such as normal blow, time delay, etc. DO NOT use makeshift fuses or short the fuse holder. This could cause a shock or fire hazard or severely damage the instrument.
OPERATION
CAUTION
DO NOT OPERATE WITH COVERS OR PANELS REMOVED. Voltages inside the equipment consist of line (mains) that can be anywhere from 100-240VAC.
DO NOT OPERATE WITH SUSPECTED EQUIPMENT FAILURES. If any odor or smoke becomes apparent
turn off the equipment and unplug it immediately. Failure to do so may result in electrical shock, fire or permanent damage to the equipment. Contact the factory for further instructions.
DO NOT OPERATE IN AN EXPLOSIVE ATMOSPHERE: Operating the equipment in the presence of flammable gases or fumes constitutes a definite safety hazard. For equipment designed to operate in such environments the proper safety devices must be used such as dry air or inert gas purge, intrinsic safe barriers and/or explosion­proof enclosures.
DO NOT IMPEDE THE CHAMBER FROM VENTING EXCESS PRESSURE. The humidification and dehumidification systems are open loop systems that pump external air into the chamber. If the chamber is not allowed to vent, pressure could build up and cause serious damage to the chamber.
USE DISTILLED OR DEIONIZED WATER SOURCE FOR HUMIDIFICATION. Build-up of contaminates on the transducer will cause stress to the transducer and electronics and resulting in premature failure and invalidate the warranty.
IF YOUR UNIT INCLUDES OPTIONAL LIQUID NITROGEN COOLING CAPABILITES, REVIEW ALL SAFETY INFORMATION IN THE LIQUID NITROGEN SAFETY ADDENDUM.
DO NOT USE IN ANY MANNER NOT SPECIFIED OR APPROVED BY THE MANUFACTURER: Unapproved use may result in damage to the equipment or present an electrical shock or fire hazard.

III. Setup Guide
Part 1: Mount the Environmental Chamber onto the Instron unit Tools Needed:
□ Adjustable wrench □ 4mm Allen wrench
□ Phillips screwdriver
Step 1 – Attach Chamber Standoffs
Insert and tighten the four 2” inch tall standoff assemblies into the 4 threaded holes in the Instron platform as shown. An adjustable wrench can be used to tighten the standoffs.
Step 2 – Raise the Instron armature
Make sure the armature of the Instron unit is fully raised to ensure it is not in the way of mounting the environmental chamber.
Step 2 – Set the chamber in place
With 2 people, carefully place the chamber centered from left to right) onto the standoffs and slide the chamber back into place until the hex standoffs and center Instron post align with the holes of the bottom metal support plate. Once in place, have one person hold the chamber steady in place, while the other person completes the next step of attaching using screws.
Step 3 – Insert and tighten screws
Once the chamber is in place and the mounting holes are aligned, utilize the four M6x25mm screws and shock mount washers (rubber side down) to attach the chamber to the standoffs. Use a 4mm Allen wrench to tighten the screws.
Step 4 – Attach rear support bracket
Attach rear support bracket to the Instron Column utilizing the T-slot nuts.
Start by placing the T-slot nuts into the channel on the Instron column and let them fall to the bottom of the channel. Thread the ¼”-20 1-inch studs loosely into the T-slot nuts. Do not tighten; the t-slot nuts still need to be able to slide in the channel.
Slide the top stud up and place the bracket onto the studs with one stud in each of the slots in the bracket. The bracket should be oriented with the side having the shorter slots placed against the column [and the side with the longer slots placed against the chamber].
Next, slide the entire bracket upward until the long slots on the bracket align with the holes in the chamber. Loosely attach the bracket to the ETS chamber using the 10-24x3/4” pan head screws, #10 split washer, and #10 washer. Do not tighten pan head screws.
You can now finger tighten the studs on the Instron column to lock the T-slot nuts into place.
Next thread the ¼”-20 thumb nuts loosely onto the studs on the Instron column. Do not tighten.
With the bracket in place flush against both the Instron column and ETS chamber, proceed to tighten the screws and thumbnuts. Utilize a Phillips screwdriver to tighten the 10-24x3/4” pan head screws.
Be careful to avoid placing any strain on the chamber that could cause stress/cracking. If necessary, STOP, and loosen the hardware and readjust the position of the bracket to eliminate any physical stress and then tighten.
Refer to documentation from Instron for your
model of single column Instron unit.
Step 5 – Set limits on Instron column
To avoid the Instron unit armature from destroying the chamber accidently, set your lower physical stop limit on your Instron armature to a safe level to avoid physical contact with the chamber.
