maintain the integrity of the door system shortens the lifespan of the unit.

EPLACEMENT
The door gasket is a low-wear item. It typically only needs to be replaced due to being cut or
nicked. The risk of this type of damage can be significantly reduced by opening the door to 130°,
keeping it well out of the way of shelves or sample trays being removed from or inserted into the
chamber.
Procedure: The manufacturer recommends having a rubber mallet and exam gloves on hand to
perform this procedure. Cover the mallet head with a clean plastic bag to help reduce
contamination of the door. Wearing exam gloves likewise reduced the chance of contaminating the
chamber door interior.
1. Remove the old gasket by pulling it out of the gasket well in the door.
2. Insert a few centimeters (inches) of the narrow side of the replacement gasket into the
gasket well on the top of the door.
3. Insert a few centimeters (inches) of the gasket’s narrow side gasket into the well on the
bottom of the door.
4. Insert a few centimeters (inches) of the narrow side of the gasket into the well on the left
side, then on the right side of the door.
5. Continue around the door in this fashion, alternating sides.
a. The rubber mallet can be used to help seat the gasket. Use moderate strokes.
