K-MINC-1000 Instructions for Use
English
6. Service and maintenance
6.1 Changing filter, gas lines & humidification flask
Proper service, maintenance and storage must be provided to preserve the MINC and ensure its proper functioning.
To protect the patient from infection, all disposable items that come into contact with human tissue (such as test
tubes and tubing) must be sterile. Disposables must be discarded after each patient use.
To change the filter, gas lines and humidification flask:
1. Ensure the gas flow is turned off.
2. Lift both heater chamber lids, and the centre chamber lid. Detach and remove the old filter, gas lines and
humidification flask.
3. It is recommended to clean the entire device prior to installing a new filter, gas line and humidification flask.
Refer to § 6.2.
4. Prepare and insert a new flask as detailed in § 3.8.
5. To recommence operation of the MINC:
a. Turn the gas flow on.
b. Check that bubbles can be observed in the humidification flask.
c. Check that the gas line supplying each chamber is not kinked or pinched.
d. Close the lid of the centre chamber and adjust the flow rate if required.
6. Allow 4 hours for the water to heat and saturate with CO

.
This process can be accelerated by:
1. Pre-heating the aseptically prepared humidification flask to 35°C in step 4, and
2. Purging the system at least 3 times in quick succession as in step 5.
This will allow immediate use of the device.
6.2 Cleaning the device
Before periodic cleaning of the MINC, remove the contents of the incubation chambers.
Shut down device. Refer to § 5.7.
It is recommended that the MINC be cleaned with aqueous 70% alcohol (ethanol or isopropyl). Moisten a cloth and
wipe all internal and external surfaces of the device.
Do not immerse the device in the cleaning solution.
Clean the gas vents located in the centre of the front of the chamber lids by scrubbing the hole with a small “pipe-
cleaner” wetted with the aqueous 70% alcohol solution.
Following cleaning, leave the lids of the unit open to allow sufficient time to ensure that all alcohol fumes have
dissipated.
Purified water may be used to wipe device surfaces at times when the use of alcohol solution is not appropriate.
6.3 Biannual functionality testing
In order to preserve the MINC and maintain its safety, regular inspections are necessary for early detection of
possible malfunctions.
The user or a qualified technician must regularly test the device to assess its functionality.
The following must be tested on a biannual basis:
• Temperature
• Gas Flow Rate
• External Alarm Contacts
WARNING:
To guarantee safe
operation, it is necessary to carry out
proper care and maintenance of the
MINC and disposables. Regular checks
to confirm correct functioning of the
device are recommended!
New and repaired products must be
prepared and tested according to the
user manual before use.
WARNING: BIOLOGICAL
HAZARD.
Do not use a
contaminated humidification flask
in the MINC. It is recommended that
the sterile humidification flask be
replaced each time the sterile water
needs refilling, or replaced regularly
with a maximum period of use being
4 weeks, in order to avoid bacterial
contamination of contents.
WARNING: ELECTRIC
SHOCK HAZARD.
Do not
immerse the MINC!
IMPORTANT NOTE:
This
functionality testing must be
performed every six months.
