Notes contain a tip or important information pertinent to the subject matter.
Cautions contain information to help you prevent actions which could damage the
instrument.
Warnings contain information to help you prevent actions which could cause
personal injury.

Dewar Precautions Gemini VII 2390 Confirm
2 Gemini VII 2390 Confirm Installation Instructions and Checklist Feb 09
Dewar Precautions
We recommend the following be observed when handling Dewars containing liquefied gases:
• Protect yourself by wearing 1) goggles (or a face shield), 2) an insulated or rubber
apron, and 3) insulated gloves.
• When pouring liquefied gases from one container to another: 1) cool the receiving con-
tainer gradually to minimize thermal shock, 2) pour the liquefied gas slowly to prevent
splashing, and 3) vent the receiving container to the atmosphere.
• Use a plastic stirring rod when stirring substances in a glass Dewar containing lique-
fied gases (or other materials suitable for extremely low temperature). Do not use a
glass or metal stirring rod unless it is coated with some type of soft protective coating.
• Do not remove the mesh covering from a glass Dewar. This covering enables you to
maintain a more secure grip on the Dewar.
• Do not handle heavy objects above a glass Dewar. If unavoidable, place a protective
cover over the Dewar’s opening. If an object of sufficient weight is accidentally
dropped into the Dewar, shattering may occur.
Preparing for Installation
Before you begin installation, make sure the customer has thoroughly reviewed the Gemini
VII 2390 Preinstallation Checklist. Make sure all required equipment and supplies are
unpacked and the required personnel are available.
Always handle Dewars with care. Any product incorporating a vacuum is a potential
safety hazard and should be treated with caution. Always observe the precautions
listed below.

Connecting Multiple Analyzers
An ethernet switch is required when connecting multiple analyzers to the computer.
1. Plug the ethernet switch power cord into an appropriate power source.
2. Connect one end of an ethernet cable to the ethernet port on the computer and the other
end to a numbered port on the ethernet switch. Do not use the Uplink port.
3. Connect one end of an ethernet cable to the Ethernet connector on the left side of the
analyzer and the other end of the cable to a numbered port on the ethernet switch.
4. Repeat Step 3 for each analyzer you are installing.
Be sure cables are not connected to the
ethernet switch’s uplink port.

Feb 09 Gemini VII 2390 Confirm Installation Instructions and Checklist 5
Installing the Vacuum Pump
The Gemini requires an external vacuum system that meets these specifications:
Vacuum source achieving 20 x 10-3 mmHg (or better) at the instrument inlet for oil-based or
oil-free pumps.
For oil-based pumps: an anti-suckback valve is required to prevent oil from being admitted
into the Gemini should there be a power failure. A device to reduce oil vapor backstreaming is
also recommended.
Two types of pumps are available from Micromeritics:
Use the appropriate instructions for the customer’s vacuum pump:
•“Oil-Based Pump” on page 6
•“High-Vacuum/Oil-Free Pump Combination” on page 16
•“Non-Micromeritics Provided Vacuum Pump” on page 18

Oil-Based Pump
Supplies Needed to Install an Oil-based Vacuum Pump with Alumina Trap
Preparing the Alumina
1. The activated alumina must be thoroughly dried before using.
Turn on a drying oven and set the temperature to 300 °C to preheat.
Micromeritics Supplied User Supplied
• Vacuum pump
•Alumina
•Aluminatrap
• Exhaust port filter
• Vacuum pump hose
•Clamps
• Pump oil
•Dryingoven
• Flat-blade screwdriver
• 10-mm screwdriver
300 °C

2. Pour approximately 180 grams of fresh alumina into a glass or metal container (250 mL if
a graduated beaker is used). Place the container into an oven preheated to 300 °C.
3. Bake the alumina for two hours. Remove the baked alumina from the oven and allow it to
cool until lukewarm.
Do not perform this procedure on used alumina. Resultant oil vapors may cause a fire
or explosion.

Preparing the Alumina Trap
1. Insert an O-ring into each of the end fittings.
2. Screw one of the end fittings onto the trap body clockwise.
3. Be sure the trap body is dry and the alumina pellets are cool. Pour the pellets into the trap
until they are level with the top of the trap body.
4. Screw the other end fitting onto the trap and tighten securely by hand.
Be sure alumina pellets are cool. Adding hot pellets to the trap body may warp the
body and cause an improper seal of the O-ring.

5. Lightly tap both ends of the trap body on the work surface. This will remove any
remaining dust from the pellets.
Closing the Ballast Valve
The ballast valve should remain closed during the operation to obtain the best vacuum. Make
sure the valve is turned completely clockwise.

Installing the Alumina Trap
1. Lift up and remove the cap on the intake port.
2. Place a centering ring on the intake port. There are two types of centering rings; use the
one with the smaller opening.
3. Place the trap on the centering ring.
Place an opened clamp around the flange of the intake port and the flange of the trap.
Swing the clamp fastening screw toward the intake port until it fits into the slot in the
other half of the clamp. Tighten the wing nut securely by hand.

Checking the Pump Oil Level
1. Check the level of the vacuum pump oil.The oil level should be halfway between the
indicator lines in the oil-level window.
2. If you need to add oil, go to Step 3. If you do not need to add oil, proceed to “Installing the
Exhaust Port Filter” on page 13.
3. Remove the plug from the oil-fill port.
4. Slowly add fresh oil to the port until the level is midway between the indicator lines in the
oil-level window on the front of the pump.

5. Replace the oil-fill plug; turn clockwise to tighten.
Do not allow oil to rise above the midway position. Doing so may cause oil to splash
into the exhaust filter and contaminate it.

Installing the Exhaust Port Filter
1. If the exhaust port is closed with a clamp, loosen the wing nut of the clamp at the exhaust
port. Swing the clamp away from the exhaust port and remove it.
2. Make sure the centering ring remains on the port.
If the exhaust port is closed with a cap, remove the cap.
3. Place the filter on the centering ring. There are two types of centering rings, use the one
with the larger opening.
4. Open the clamp and place it around the flange of the exhaust port and the flange of the
exhaust filter.
5. Swing the clamp fastener screw toward the exhaust port until it fits into the slot in the
other half of the clamp. Tighten the wing nut securely by hand.
