10.4.2 Replacement without an Internal Glove Port Cover
Without an internal glove port cover, the old glove can be used to cover the port while the new
glove is installed.
1
Press the glove that is to be replaced into the box.
2
Remove the inner glove port “O” ring (that which is closest to the window).
3
Fold back the glove onto the outer “O” ring, taking care not to let the glove come off of the
port.
4
Compress the new glove as much as possible to remove excess air.
5
Install the new glove over the glove port, over the old glove.
6
Install the inner “O” ring onto the glove port, over the new glove.
7
If possible, purge the new glove by venting working gas into it via a separate gas line. (This
removes as much air as possible, and hence reduces the amount of air being introduced into
the system.)
8
From the inside of the Glovebox, using the other glove, remove the old glove by taking it
into the Glovebox.
9
Install the outer “O” ring onto the glove port, over the new glove.
10
Remove the old glove from the box via the Antechamber, and discard it properly.

solid-state relays. Some systems will require the white backing plate to be removed prior to
removing the power supply and the solid-state relays.
10.4.4 Circuit Breakers
When replacing a circuit breaker, always use a replacement part of the same rating.
1

the wire to which they are attached.
3
Depress the two tabs on the breaker body and Press out through the front door.
4
Install new circuit breaker in reverse order.
