the controller and labeled “CO2 IN”. Push the tube all the way in into the Swift-Fit
connectors. To remove the tube, pull the tube out while pushing the black ring on the
Swift-Fit connector. Follow the arrow on the Pressure Gauge for the correct gas flow
direction as illustrated in Figure 7. It is important to ensure that the tubing is properly
inserted all the way into the Swift-fit connector in order to avoid gas leaks (See Figure
6).
Figure 6. Avoid gas leak: make sure tubing is pushed all the way into the Push-in to-Fit connector
4.
Use the rigid tube, TUBE D (supplied, see paragraph 7.1), to connect the Air Output
Swift-Fit connector on the front panel of the OKO-AP to the Air Inlet Swift-Fit connector
on the rear panel of the Control Unit (Figure 4).
5.
Use TUBE E (supplied, see paragraph 7.1) (assembled as follows: 2m long, 6mm O.D.
blue rigid tube + to 0.5 m long 4mm I.D. silicon transparent tube + 0.2 micron porous
hydrophobic 0.5 m long 4mm ID silicon transparent tube) to connect the Air +
CO2 output Swift-Fit connector on the rear panel of the Control Unit to the Inlet barb
connector on the Humidifier bottle, as illustrated in Figure 4 and Figure 5.
6.
Use TUBE H (supplied, see paragraph 7.1) (assembled as follows: 0.5 m long 4mm ID
silicon transparent tube + 1 m long, 2mm ID silicon transparent tube wrapped in
insulating material) to connect the Outlet barb connector on the Humidifier bottle to the
miniature barb connector on the Incubating Chamber, as illustrated in the Figure 4 and
in Figure 5.
It is possible to use additional filters or filtering devices to further filter the gas mixture
prior to its entrance into the incubation chamber further reducing the risk of
contamination. If you choose to install an additional filter insert it after the Control Unit
and before the hydrophobic filter included in the tubing assembly of TUBE E.
Note
►
Use OKO AP when no Air pressurized tank is available
.
Note
►
Whenever your system is equipped with Premixed gas pressurized tanks with
safety valve and pressure gauge with regulator within the range 0-6 bar (not supplied),
you can directly connect the Premixed gas to the Air inlet of the Control Unit using Tube
D and use the Air regulation in the front panel to control the flow.
