Replacing environmental seals
Introduction to
environmental
seal
replacement
A faulty environmental seal can allow moisture to enter the cabinet, which in
turn can lead to equipment failure. It is important that the seals are inspected for
signs of wear or damage whenever the cabinet doors or lid are opened.
Replacing an
environmental
seal for the lid
The environmental seal for the lid consists of a U-shaped rubberized seal that
fits over the metal lip on the top of the cabinet (see Figure 3-3).
The procedure for replacing the seal for the lid is as follows:
1. Open the cabinet doors, release the lid catches and then lift the lid so that
it locks in position.
2. Pull the old seal off the metal lip.
3. Measure the length of the new seal against the old seal and trim to the
correct length, if necessary.
4. Starting at the centre, press the new seal firmly onto the metal lip all the
way around. Ensure that both ends of the seal meet at the centre of the
front lip.
5. Close the lid and the cabinet doors.
The procedure for replacing the environmental seal for the lid is now complete.
Replacing an
environmental
seal on a door
The environmental seals for the doors consist of four strips of self-adhesive
gasket, fixed to the inside panel of each door.
The procedure for replacing the seal for a door is as follows:
1. Open the cabinet doors.
2. Trace a line around the inside edge of each seal strip as a marker for
positioning the new seal strips.
3. Remove the old seal strips. Remove all traces of adhesive using a suitable
solvent.
4. Fit the new seal strips, ensuring that the inside edges align with the marks
made prior to removing the old seals.
5. Close the doors.
The procedure for replacing the environmental seal for a door is now complete.
