K-MINC-1000 Instructions for Use
WARNING: The gas inlet must
be connected to a regulated pressure
source set to 150 kPa (tolerance
1
of ±15 kPa) at the MINC to operate
correctly!
IMPORTANT NOTE: Cook
Medical strongly recommends the
use of automatic gas cylinder change
over units to ensure continuity of gas
supply.
WARNING Use only a suitable
medical gas grade pressure regulator
set to a nominal 150 kPa. Do not use
flow restrictors or flow regulators in the
gas stream.
WARNING: Silicone tubing must
not be used in the connection between
gas cylinder and the MINC , or in series
connections of multiple devices.
3.7.2 Gas cylinder regulator recommendations
The following information is a recommended guide for the selection of a gas cylinder regulator used with the
MINC. Following these guidelines will provide a reliable gas connection between a gas cylinder and the device.
The gas regulator chosen in conjunction with the MINC is an important part of the gas delivery system and must be
designed and manufactured to carry medical gases. As the gas specified to be used with the MINC is of high purity
and accuracy it is important that the regulator used does not contaminate the gas stream.
Please specify the information below when ordering your gas regulator:
• Single stage high purity regulator.
• Metal to metal diaphragm seal.
• Stainless Steel diaphragm, which doesn't contaminate high purity gas streams.
• Dual scale gauges (optional).
• Fully configured for a special blend medical grade gas cylinder.
• Delivery pressure of 150 kPa ± 15 kPa at the MINC gas inlet.
• A minimum flow (without undue supply pressure sag) capability of 350 mL/min per MINC is required during the
purge cycle.
• The outlet fitting of the regulator is to be a Swagelok® SS-400-1-4RT fitting to fit the connecting hose supplied
with the MINC.
3.7.3 Connection to gas cylinder
Connection of the MINC to gas cylinder is achieved by use of the supplied braided connecting hose. It has a non-
toxic, low permeability PTFE lining which prevents the loss of CO
more permeable materials such as silicone and PVC. Silicone tubing is relatively porous to pressurised CO
must not be used anywhere in the connection from the gas cylinder as the correct gas concentrations may not
reach the MINC chambers.
The MINC and connecting hose are fitted with Swagelok® ¼" series tube fittings. The standard hose length is
3 meters. Alternative lengths are available in 60 cm, 100 cm, 6 m, 10 m or 20 m. A union fitting is available to
connect gas hoses. Refer to your local Cook Medical representative for more information.
A pressure regulator with these fittings should also be used.
These fittings use a tapered ferrule to provide a leak-free seal upon connection.
Ferrule
The ferrules on the connecting hose have been pre-swaged before shipping. Therefore, any ferrule and backnut on
the cylinder mounted regulator will be surplus to requirements.
