SECTION 3
INSTALLATION AND OPERATING PROCEDURES
10/87
Attach the desired length of 5/32” (4 mm)
I.D. oxygen delivery tubing (7 Fig. 3) to
the humidifier and attach either a
cannula or a suitable mask. Tubing should
not exceed 50 feet (15 m).
Condensation from the humidifier may
occur in longer lengths of tubing or with
tubing laying on a cold floor. This can be
reduced by using the removable humid-
ifier stand. To use the stand, attach one
end of the delivery tubing to the oxygen
outlet fitting and the other end to the
plastic fitting on the humidifier.
The DeVO/MC44 oxygen concentrator
may now be used.
