4. OPERATION PROCEDURES
Main Operation
Prepare dryer manifold, vacuum pump, vacuum hose, tandem tube, and other equipment necessary to
operation process.
Example vacuum pump: PD52 (from YAMATO Scientific)
Displacement volume: 50/min, maximum vacuum pressure: 6.7

In some cases, sound of the refrigeration unit may be higher or
lower, depending on initial operation status and surrounding
temperature. This phenomenon is not abnormal.
3. Install vacuum chamber.
1. Be sure there is no dust or other contaminants on the trap
seal or vacuum chamber before flask installation.
Damage to or contaminants on chamber and seal weaken
vacuum pressure.
2. Gently place flask mounting vacuum chamber on trap seal.
If vacuum chamber does not sufficiently adhere to trap seal, a
vacuum leak may result.
The above holds true for Manifolds A & B, etc. as well
