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.
Base provides support for the control unit and adjustability to align the Control Unit Base control unit with the chamber which will mounted to the Instron unit. The Model 5502 includes one chamber as standard. However, chambers are Chamber frequently customized to the application and quantity and size may vary.
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.
Page 7
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.

Part 2: Place the Control Unit on the Base and attach to the Chamber Tools Needed: □ 3/16” Allen wrench □ Adjustable wrench □ Ruler or tape measure □ Phillips screwdriver Step 1 – Place the base in position Set the control unit base on the work surface to the left of the Instron unit with the front of the base [the long vent slots in the top of the base should be to the front].
Page 10
Step 3 – Place the control unit on the base The control unit should be positioned on the front half of the base with the front of the control unit approximately aligned with front of the base. Set the control unit on the left 3/4 of the base.

Step 5 – Close the latches To complete the attachment of the control unit to the chamber and provide a tight seal, turn each of the latches clockwise from inside the chamber. If any significant resistance is encountered, do not force the latch. Any significant resistance may indicate misalignment of the latch mechanism with the slot;...

Step 5 – Optional LN2 System IMPORTANT! If the LN2 cooling system is going to be REVIEW ALL SAFETY PRECAUTIONS used, it is IMPORTANT to turn off all of AND INSTRUCTIONS the other temperature and humidity systems (reverse Steps 2 and 4 – Turn o Liquid Nitrogen Safety Addendum OFF the fan and turn OFF all 4 operating o Liquid Nitrogen Cooling System Set-Up...
IV. Operation Guide Control Panel Button Description Functionality POWER This switch disconnects all power going to the Chamber Systems. “I” is “ON”, “O” is “OFF”. LN2 (optional) Turns on power to the liquid nitrogen (LN2) cooling system (if installed). No longer used TEMP - INCR Allows the user to manually disable the Temperature Heating System.

IX. Liquid Nitrogen Safety Addendum Reference: http://engineering.dartmouth.edu/microengineering/ln2.html Properties of Liquid Nitrogen (LN2) 1. It is extremely cold: 77.3K = -196C = -320F at atmospheric pressure. This can cause severe frost bite. 2. On vaporization, it expands by a factor of 700; one liter of liquid nitrogen becomes 24.6 cubic feet of nitrogen gas.
Dewar to bleed the tank until a solid thick cloud of gas comes out. Once a cloud of gas is visible close the liquid nitrogen output valve on the Dewar. Attach the open end of the transfer hose to the ETS Control Valve input. Open the liquid nitrogen output valve on the Dewar.
