Gas connection for UNO-T-H-PREMIXED
UNO-T-H-PREMIXED is suitable or applications with premixed gas supply. Follow the steps below for a
correct installation:
1.
Install the GF-REGULATOR between the premixed gas supply and the Humidifier (see Figure 13). Use
TUBE-A to connect the premixed gas supply to the push to fit input connector for a 6 mm O.D. rigid tube
of the GF-REGULATOR (see Figure 13).
During this operation make sure that both the premixed gas tank and the GF-REGULATOR are closed.
Be careful to follow the direction of the arrow on the rear of the GF-REGULATOR for the correct gas in-out
orientation (see Figure 12).

The premixed gas tank must be equipped with a pressure regulator to decrease the pressure from
the pressure tank to 4 barg (58 psig).
Do not exceed 10 barg (145 psig) for GF-REGULATOR inlet gas pressure. This may damage the GF-
REGULATOR.
2.
Connect the blue rigid end of TUBE-C to the output connector of GF-REGULATOR. Connect the silicon end
of TUBE-C to the Gas Inlet gas connector of the Humidifier (see Figure 13). TUBE-C is equipped with a
PTFE filter in the middle. Make sure to install the TUBE-C in the direction of the gas flow indicated by the
labels on both ends of TUBE-C and on both sides of the PTFE filter.
Tip
►
Replace the PTFE filter each 2-3 months of continuous operation or if you see water in the inner part
of the filter.
Do not use TUBE-C without the PTFE filter.
