MAINTENANCE

1-14 Introduction
Fire hazard. Concentrated oxygen increases the risk of fire.
Do not carry the Companion 1000/T under clothing. This unit
normally vents oxygen. Wearing a Companion 1000/T under
clothing may saturate fabrics with oxygen and cause them to
burn rapidly if exposed to sparks or flame. It may take
several hours for oxygen levels in fabrics to return to normal.
The Companion 1000/T Pre-Fill Inspection, Filling, and Post-Fill Inspection procedures
should be performed every time the patient's Stationary reservoir is filled. This provides
routine assessment of the functional status of the Companion 1000/T. Functional
problems observed during these procedures must be corrected before placing the unit in
service.
Use the information in Table 1-3 as a guide to clean, inspect, and test the
Companion 1000/T when functional problems are observed or as needed.

Cleaning Remove the covers and clean the interior and exterior of each
cover with a mild detergent and water. Wipe dry with a towel. Use
cotton swabs in tight places. Use Scotch-Brite abrasive pad with
detergent to lightly buff out scuff marks.
Clean the plumbing with detergent and water. Dry with a towel
and oil-free compressed gas.
Replace the moisture pad.
Inspection Inspect the side covers for cracks, warpage, and discoloration.
Inspect the flow control knob for cracks. Verify that the knob is
tight on the valve shaft.

labels (Figure 1-7) are present and legible.
Verify that the carrying strap and shoulder pad are in good
condition.
Verify that the vent valve lever operates smoothly without rubbing
on the side cover. When in the closed position, the lever should be
flush with the side cover and not exhibit excessive free play.
