Warning: Use of the RS-232 service connector by anyone other than qualified, factory-trained per-
sonnel may damage the instrument and result in harm to the patient. No connection to this port is to
be made when device is operational and connected to a patient. Patient injury may occur.
Warning: The humidifier has been designed and tested for use with Hudson RCI Branded acces-
sories and breathing circuits. Use of non-approved circuits or accessories with this unit may cause
an unsafe condition. See the current issue of the Hudson RCI Catalog or go to the Hudson RCI
Website at www.hudsonrci.com for compatible circuits and accessories validated for use with the
CONCHATHERM Heated Humidifiers.
Warning: Electrical Short Hazard: Do not immerse this device in water or other fluids for cleaning.
Do not autoclave, gas sterilize or pasteurize. Severe damage will result.
Warning: Only connect this device to a Hospital Grade Grounded 120 V ~ outlet, with the power
cord supplied in the original packaging. This device has been developed to operate over the voltage
ranges noted on the name plate label for use in foreign countries. If device is used in areas outside
the United States, ensure a Hospital Grade, grounded compatible power cord is utilized. Please call
Teleflex Medical’s customer service to obtain Foreign Country power cord specification for your appli-
cation.
Caution: Federal law (USA) restricts this device to sale by or on the order of a physician.
Caution: Always operate the humidifier in a vertical position with the water reservoir properly
mounted.
Caution: Temperature patterns within the system associated with normal operation will be disrupted
if there is insufficient water to pass through the system, causing a high temperature alarm.
Caution: Do not operate the humidifier with a dry or disconnected reservoir or without a column
installed. Severe damage may result.
Caution: Hudson RCI Branded circuits and accessories are Single Patient Use only. With the
exception of the Temperature Probes, they are not cleanable or re-useable. Accessories should be
changed after a maximum of 14 days of use, or when noticeably contaminated by the patient or
excessive leakage is observed.
Caution: Replace the power fuse only with one of the same rating.
Caution: Monitor the Inspiratory and Expiratory Circuits periodically for excessive condensation
(rainout).
Caution: In the Invasive, or Sub-glottic Mode, the humidifier is designed to deliver a minimum fluid
output of 30 mg H
2
O/L at 30º C, for the proximal airway temperatures at zero gradient and with the
recommended Flow Rates listed in the Specification Section of this manual.
• Use of Positive or "Sun" gradient settings in some conditions can result in humidity outputs
at the patient of less than 30mg H
2
O/L at 30º C.
• Visually inspect for condensation droplets in the inspiratory circuit after one hour of
operation, and periodically thereafter.
Caution: Some Ventilators produce elevated gas temperatures at the patient inhalation port which
can reduce the amount of relative humidity in the circuit. Visually inspect for condensation droplets
in the inspiratory circuit after one hour of operation, and periodically thereafter.
Caution: Monitor the Inspiratory and Expiratory Circuits periodically for excessive condensation
(rainout). Use water traps to collect rainout when using non-heated wire breathing circuits.
