A03-0412 voltage step-down transformer - If your facility supply voltage is 255V or higher,
then the use of this transformer is required.
A03-0411 voltage step-up transformer - If your facility supply voltage is 208V or lower, then
the use of this transformer is required.

Generator Controls
Check that the power cord of the generator is properly connected to the generator receptacle.
Rotate clockwise to lock. Check that the power cord of the generator is connected to the proper
power supply outlet.
During normal operation, the generator’s power switch is illuminated green. The compressor
pressure gauge indicates a pressure between 125 to 130 psig (8.6 to 8.9 barg). If the pressure
drops below 125 psi, then the outlet flow is too high. Set the 3 regulators to the specified values
by the instrument. The flow rate for each gas is displayed by the flow meter designated for each
gas. Refer to the flow label on the top of the NitroFlow TG2 cabinet for the correct flow reading at
standard conditions.
Do not remove the cover while the system is pressurized.
The generator has its own automatic water drain system. The 3 filters located on the back of
the generator are equipped with pneumatic drains that open when the water level reaches a
predetermined point. The compressor drain operates every 10 minutes, opens for 2 seconds; the
two internal filter bowls also drain every 10 minutes.
The generator cabinet has two LED indicators (see Figure 9): Power ON, and High Temperature.
The green LED remains illuminated during normal operation. The other LED indicator,
“High Temperature” remains unlit if the compressor is functioning properly. Red illumination
of the High Temperature LED signals a fault condition and warns the operator that the unit
requires servicing.
Ensure all 3 gas outlets at the back of the generator are not connected to pipework and are closed
using the yellow shut off valves on the back of the NitroFlow TG2. Rotate the Power Switch on
the front panel of the generator (see figure 9) to ON by turning it clockwise. The generator will start
and the green LED will illuminate. The Compressor Output pressure gauge will slowly increase to a
maximum set pressure of 137psig (9.4 barg). Full pressurization will occur within 10 minutes. Allow
the system to run for 90 minutes to reach full operating temperature. Using the regulators on the
front of the unit, adjust the outlet pressure on each gas line to 20psi and open the 3 gas outlets slightly
using the yellow shut off valves at the back of the generator allowing the system to vent to atmosphere
for approximately 1 hour (note: venting to atmosphere at 20psi is not too loud and will allow the
desired purge. Opening the valves fully will “overflow” the generator and it will not maintain pressure).
Connect the gas lines to the back of the generator and allow them to purge the length of pipework to
atmosphere for another 15 minutes. Close the 3 gas outlets using the yellow shut off valves. Connect
the now purged lines to the application and slowly re-open the yellow shut off valves to pressurize
the gas lines.
This procedure should also be followed any time the generator is fully up to
operating temperature and then powered off for more than 30 minutes.
