Chapter 3: Getting Started

Product Service 1-800-522-7658

The Stoppering Tray Dryer is now installed and must be tested to make certain the

system is free of leaks. To test, turn on the Freeze Dry System refrigeration and

allow the temperature to reach –40° or lower. Close the door of the Tray Dryer

and make sure the Stoppering Control is in the “LOWER” position and the Vac

Release control is in the “CLOSED” position. Start the vacuum pump and

monitor the vacuum gauge. The vacuum on the Freeze Dry System should reach

0.133 mBar within 30 minutes and should achieve an ultimate vacuum of 0.040

mBar or lower within 18 hours. If 0.040 mBar cannot be achieved, consult the

troubleshooting section of this manual and of the manual supplied with the Freeze

Dry System.

Venting the Vacuum Pump

If any materials will be placed in the Stoppering Tray Dryer

that can liberate hazardous gases when heated, the vacuum

pump exhaust must be vented to a fume hood or other

ventilation device.

Electrical Connection

Plug the power cord into the receptacle on the back of the Stoppering Tray Dryer

and plug the other end into a suitable power receptacle.

DO NOT ATTEMPT TO PLUG THE STOPPERING TRAY

DRYER INTO THE FREEZONE FREEZE DRY SYSTEM.

CAUTION: When the appropriate power cord is plugged into

the power receptacle on the rear panel of the tray dryer, the

clamp on the tray dryer receptacle should be tightened to

prevent the cord from accidentally being switched with the

freeze dryer cord located underneath the tray dryer. (The

freeze dryer may require different mains A.C. voltage and

switching these power cords may cause damage).

Chemical Resistance of Freeze Dryer

Components

The FreeZone Freeze Dry System and Stoppering Tray Dryer are designed to be

chemically resistant to most compounds that are commonly used in freeze drying

processes. However, by necessity, the Freeze Dryer is comprised of a number of

different materials, some of which may be attacked and degraded by certain

chemicals. The degree of degradation is dependent on the concentration and

exposure duration. Some of the major components of the FreeZone Freeze Dry

System that are susceptible to degradation are as follows:
