The following procedures should not be at-
tempted by anyone who has not had proper
training or authorized to do so.
A. Cover Removal

secure the cover to the main assembly. Do
not loosen the lower screws inside the cut
out slots in the bottom of the cover.
NOTE
The upper screws and lower screws are not the
same. Do not mix them. The upper screws are
for threading into the plastic of the front and
rear panels. DO NOT use the finer threaded
lower screws for this.

B. Cover Installation
1. Reverse previous procedures for cover
installation.
NOTE
When installing the upper screws, attempt to
reuse the original threads. The easiest way

then begin to turn the screw clockwise to
tighten to 15-18 in. lbs. Do not over tighten.

For better system performance, the lter element
should be checked per the Maintenance Schedule
(Subsection 5.02), and either cleaned or replaced.
1. Remove power from the power supply;
turn OFF the gas supply and bleed down
the system.
2. Remove the system cover. See "A Cover
Removal" in this section.

from the lter assembly. Number 1 in the
following illustration.

locking ring on the lter assembly tting,
then pull on the hose to release it. (Num-
