Installation and Setup VirTis BenchTop 2K, 4K and 6K

Freeze Dryer Setup
To set up your BenchTop unit:
Note: Refer to Basic Operation for complete equipment operation instructions.
1. Install a condenser gasket (black rubber ring with a slit in it) on the top of the
unit. It should have a light film of vacuum grease on the outer surface.
2. Prepare the unit for your intended use.
a. If the unit is to be used as a standalone freezer, cover the condenser
with a plain cover plate to prevent air circulation from warming the
samples. Skip to step 5.
b. If the unit is to be used as a manifold dryer, place a manifold adapter
plate (clear acrylic or stainless steel circular disk with a hole) over the
gasket.
c. If you are using an acrylic drum manifold, place a second condenser
gasket around the bottom lip of the manifold.
BenchTop with acrylic manifold.
d. If you are using a stainless steel manifold, place the supplied O-ring in
the groove of the manifold adapter plate.
3. If using a manifold, attach Quickseal valves to each port on the manifold and
ensure that each is in the closed position. For more information, refer to the
Quickseal valve section in Chapter 5.
Note: Quickseal valves are siliconized at the factory. Vacuum grease is not required.
4. If using an acrylic drum manifold, apply a thin coating of vacuum grease to the
tapered surface and place the tapered plug in the top center of the manifold.
Slowly turn the plug 360° clockwise and then 360° counterclockwise. This will
ensure a good seal between the surface of the plug and the manifold.
5. Plug the unit into an appropriate outlet and switch on the circuit breaker
located on the rear of the unit. The control panel display will illuminate.
