Isotemp 600 Series incubators incorporate a durable, silicone door gasket
to minimize heat loss. Should the gasket become defective or be damaged,
it may be replaced by following the procedure below.
Note
Study the method of door gasket attachment before starting
disassembly. Understanding will avoid confusion later in this process.
s
1. Set the power switch to off position and open chamber door.
2. Carefully remove and retain hardware from door hinges (case side). Lay
door on a flat surface with the handle over the edge.
3. Note the joint position of the old gasket. This is where the new gasket
installation will start.
4. Bend back the old door gasket and remove the Phillips head screws
attaching the gasket.
5. Remove the old door gasket.
6. Loosely install two screws through the stainless steel liner and into the
door wrap to align these pieces during the installation of the new
gasket. Once one side of the new gasket is installed, these screws will
need to be removed to install the new gasket.
7. Begin installing the replacement gasket at the joint position of the old
gasket. Stretch the replacement gasket around the corners of the liner
to avoid bunching up of the gasket material.
8. Install a Phillips head screw as the gasket rounds each corner to keep
the gasket properly stretched. (The screw goes through the liner, pierces
the gasket and threads into the door wrap.)
9. After all four corners are secured, install the remainder of the Phillips
head screws. Make sure there is no gap at the gasket joint; stretch the
gasket slightly, if necessary.
10. Reinstall the door onto the case with hinges.
