93/42/EEC correct manner
Ensure that invasive mode is set for
patients that have bypassed airways.
The use of breathing circuits, chambers or
other accessories which are not approved
by Fisher & Paykel Healthcare may impair
performance or compromise safety.
Ensure that both temperature probe
sensors are correctly and securely fitted.
Failure to do so may result in temperatures
in excess of 41 °C being delivered to the
Ensure maintenance of grounding integrity
by connection to a "hospital grade"
receptacle. Always disconnect supply
When mounting a humidifier adjacent to a
patient ensure that the humidifier is always
positioned lower than the patient.
The operation of high frequency surgical
equipment in the vicinity of the humidifier
may adversely affect its function. If this
occurs, the humidifier should be removed
from the vicinity of such devices.
Do not touch the glass tip of the chamber
temperature probe during use. Keep black
connectors dry at all times.
Check accessories for any physical damage
before use and replace if damaged.
CLEANING HC550 Heaterbase Using a damp cloth, clean the humidifier with either of the following: Isopropyl Alcohol or normal dishwashing detergent.
CAUTION: DO NOT immerse the heaterbase or temperature probe electrical connections in any liquid. DO NOT autoclave probes.
NOTE: Follow the cleaning agent manufacturers’ instructions carefully. It is the user’s responsibility to qualify any deviations from these procedures, both for disinfecting
efficacy and physical effect on the probe and the heaterbase. See the HC550 technical manual for more detailed instructions on cleaning.

Slide humidification chamber (A) onto humidifier base and connect breathing circuit (B) (refer to humidification chamber and breathing
circuit operating instructions for further details).
Connect the temperature probe plug (C) (REF 900MR86X) to the blue socket on the humidifier base until an audible click is heard.
Connect the heater wire adaptor plug (F) (REF 900MR8XX) to the yellow socket on the humidifier base until an audible click is heard.
Push the chamber probe (D) and airway probe (E) into the breathing circuit. Make sure the chamber probe is correctly located in its key-way
and that both probes are pushed home. The probe lead can be restrained using breathing circuit clips.
Connect the other end of the heater wire adaptor to the breathing circuit socket (G).
The humidification system is now set up and ready for use. After power on, the humidifier will operate in the last mode setting.
ATTENTION: Refer to operating instructions which accompany each accessory.

The mute button silences the humidifier's
audible alarm for at least two minutes. The
muted time depends on the alarm condition
and the severity of its cause.
Chamber & Airway Probes
Lights if either the chamber
probe or the airway probe is not
inserted into the breathing
Lights if the heater wire adaptor
or breathing circuit has not been
connected, or is damaged.
Lights if the temperature probe
is not correctly plugged into the
HC550, or the probe is faulty.
Lights when there is insufficient
water in the chamber. Check
water supply. Maximum time to
alarm of 20 minutes.
The humidifier and all
accessories should be
immediately replaced and sent
During normal operation the display
temperature is not visible. When the high
humidity alarm activates the display shows the
saturated gas temperature delivered to the
patient (the lower of the airway and chamber
temperatures in °C).
By pushing and holding the mute button for
one second, the chamber outlet temperature
then the airway temperature is displayed. The
display will then disappear.
WARNING: Ensure that invasive mode is
set for patients that have bypassed airways
This mode is for patients with
bypassed airways. The humidifier
delivers gas as close to body
temperature saturated (37 °C,
44 mg/L) as possible.
Under cold or draughty conditions the
chamber temperature may drop as low as
35.5 °C in order to maintain a dry breathing
This mode is for patients receiving
face mask therapy, and delivers a
comfortable level of humidity.
LOW HUMIDITY ALARM
An audible alarm and flashing indicator are
given for saturated gas temperatures of
35.5 °C or lower (invasive mode only).
Caused by cold/draughty conditions or very
high or low gas flows.
If the circumstances causing the low humidity
alarm cannot be changed then the audible
alarm acts as a reminder that the patient is
receiving inadequate humidity and may require
further intervention to maintain airway
HIGH HUMIDITY ALARM
A flashing temperature display showing 41 °C
or higher. The humidifier will discontinue
heating of the chamber and circuit until the
temperature decreases to within normal limits.
The Technical Manual explains how to switch
The humidifier will power ON if this button is
held down briefly, but must be held down for
one second to turn the humidifier off.
Refer maintenance to qualified service
personnel. A full technical description including
routine maintenance and service data is
contained in the Technical Manual which is
available from your supplier or Fisher & Paykel
Healthcare (REF 185043658)
