If the pump turns in the correct direction, then the putting into service can be continued.
-
Turn the disc valve in the inlet (Figure 7Figure 7. ExitOxy back view. No. 2) to the left, completely open.
-
Put the switch (Figure 7. ExitOxy back view. No. 6) to position 1 (manual on) to make the pump turn.
-
Now, turn the disc valve (Figure 7. No. 2) in the inlet slowly to the right to close it until the pressure is between
-
-0,85 Bar and -0,9 Bar.
-
If the pressure continues to -1 bar the disc valve in the inlet is closed too far. In that case, open the disc valve
again until the pressure is between -0,85 and -0,9 Bar.
-
Put the switch (Figure 7. No. 2) on position 0 (OFF) so the pump stops and the pressure slowly increases. The
pressure will increase to ± 1 Bar, which is usually the system pressure. Because of the increasing pressure the
air vent won’t blow off. (Figure 7. No. 3).
-
If the system pressure is reached and the air vent doesn’t blow off anymore, it is allowed to put the switch back
to position 1 (manual on). This will make the pump turn again and a vacuum is created in the degasser tank
again. The pressure needs to be set between -0,85 Bar and -0,9 Bar again.
-
Adjust the disc valve in the inlet if the vacuum pressure yet stays too low or becomes too big.
-
Repeat the pressurizing and the vacuum pulling until the pressure during the pumping is between the -0,85 Bar
and -0,9 Bar and stays like that during 3 or more cycles.
-
The ExitOxy is now ready for use. Seal the disc valve (Figure 7
. No. 2) again so it’s not possible to simply adjust
it.

Operation
When the pump is functioning, it will create a vacuum in the degasser tank (Figure
. No. 4). Water will be sprayed in the
tank and because of the under pressure, air bubbles will be released. These are stored in the top of the system. If a lot of
air gets into the system, the pump will stop and the system will be filled off with water and blows all the oxygen through
the air vent on the top of the ExitOxy.
If there is no air present in the system, the pump will turn on/off less easily. The system will also blow off less or nothing.
This is a sign that almost no air is present in the heating system anymore.
The pump needs to be turned on (using the time clock) in connection with the oxygen entry in the heating system (this
can occur because of diffusion).

First use
The ExitOxy can be put on mode 1 (manual) in the first week. The ExitOxy will degas most of the water in its first week in
this way. After a week can the ExitOxy be put on mode 2 (automatic on).
It is advised to check if the ExitOxy is degassing properly in its first week. This can be done in the following way:
-
Put the switch (Figure 7. No. 6) on mode 0 (OFF) while the pump is turning. The pump will stop turning so the
degasser tank can fill up with water. If the water is not completely degassed, the released air will cause an
overpressure in the degasser tank. This air will be blown off through the air vent on the degasser tank (Figure 7.
No. 3).
As more water is degassed, the pump will turn on/off less fast and less and less air will be relieved through the air vent.
This indicates a proper operation of the ExitOxy.
If after a week there is still hardly any air coming through the air vent, the ExitOxy can be put on mode 2 (automatic on).
The ExitOxy will from that moment on turn on/off according to the settings of the time clock.
*The time clock is by default set to turn on the machine for 1 hour in the morning and 1 hour in the evening. If desired, it
can be customized in the switch panel. (
