General safety instructions
TTM NoXygen®C625 is designed for stationary operation; it
is not meant for mobile system operation. The stipulated war-
ranty period applies only to a maximum of 10,000 degassing
intervals per year.
Installation must be done in accordance with national regula-
tions. Installation must be done by professionals and specially
trained staff. Information on the manufacturer, year of manu-
facture, serial number and technical data can be read on the
data plate affixed to the TTM NoXygen®C625 unit.
Take measures for temperature and pressure fusing in the
system so that the stated, allowable maximum and minimum
operating parameters are not exceeded or undercut, respec-
tively. TTM NoXygen®C625 must only be used in systems for
containing allowable fluids.
Systems using expansion vessels and pressurised expansion vessels
When operating TTM NoXygen®C625, there must be 3 litres of free expansion volume in the system.
Without this, the pressure in the system will increase and the system safety valve may release fluid in order
to reduce the pressure. If this occurs, the system’s expansion vessel like has the wrong input pressure or
there is too little room for expansion and it needs to be replaced with a larger expansion vessel.
Rule of thumb: The input pressure must be 70% of the system pressure.
NOTE: The pressure at the safety valve opening should be 30% above the system pressure.
Systems using pressure maintenance systems with compressors or pumps
Systems with pressure maintenance vessels/compressor vessels for expansion can begin to work intermit-
tently with the degasser, i.e., the expansion vessel empties and fills according to TTM NoXygen®C625's
oprertation cycles. A surge vessel measuring 50 litres should be installed in connection with the pump expan-
sion. (See the image below). The reason why this happens is that the nominal value between the opening and
the magnetic valve and the pump switch is too narrow.Then check the system pressure and system height so
that the correct system pressure is set and then give the nominal value a larger pan.
System pressure and filling of system fluid
As gasses are removed from the system fluid, the
fluid decreases in volume and the pressure within the
system is reduced. Therefore it is important to moni-
tor the system pressure and to add more system fluid
when necessary. A high gas content and continuous
operation of TTM NoXygen®can result in the system pressure falling very quickly.
An initial inspection is therefore recommended after only 24 hours of operation
System pressure
System pressure = system height (m) + 5 m.
Example
System height = 5m + 5m => 1 bar of system pressure
• Before maintenance work, the plug must be disconnected from the wall socket.
• Installation, maintenance and troubleshooting should only be carried out by
qualified personnel.
• The TTM NoXygen is usually maintenance-free but an annual function check
is recommended to ensure maintained performance, see function check page 10.
• Checking and cleaning of pre-filters should be done in conjunction with the
function check.
• In dirty systems cleaning of pre-filters needs to be done more frequently,
see page 8 and 9.

Installation
Pipe connection
• TTM NoXygen®is fitted with a ½” internally threaded connection.
The connection is made with a steel-braided hose to system’s return
conduit in front of the pump and exchanger.
• Connection to the system must always be made to the upper side
of the pipe unless a TTM MAG 54 or 76 filter is installed in front of
NoXygen on the incoming conduit.
• The distance between connection points shall be at least 300 mm
(Fig. 1 och 2).
Drip Tray
The drip tray’s ½” connection is connected to the floor drain (Fig. 3).
Mounting
For floor mounting, the TTM NoXygen®is placed on its feet so that it is
horizontal.
For wall mounting, hang the TTM NoXygen®in the unit's wall brackets so
that it hangs horizontally (Fig. 4 and dimensional drawing page 2).
Electrical Connection
TTM NoXygen®is connected by plugging in the wall plug to an earthed
socket 1-230 V, 50 Hz Alternatively, it can be connected to a fixed
earthed connection with a circuit breaker. The electrical unit should be
equipped with a residual current device.
Connection to External Monitoring (DUC)
The TTM NoXygen®is equipped with a built-in potential-free changeover
contact for buzzer alarm (Fig. 5). The switching pin is mounted externally
on the right side of the TTM NoXygen®and the alarm connector is plugged
into outputs Aand Cfor NC (Normally Closed during operation) and into
Band Cfor NO (Normally Open during operation). Operation indication is
given when the TTM NoXygen®is in operation mode (green light is on) on

Operating modes
Fast degassing/Intensive degassing
For new installations and system fluid replacement, fast
degassing is recommended. Fast degassing means that the
TTM NoXygen®runs continuously between 00:00 on Monday
and 23:59 on Friday.
The preset value is 30 days of fast degassing, which in most
cases is sufficient to degass the system. In large systems or in
systems with many air pockets, longer time may be needed to
remove all air. It is possible to increase the number of days in
fast degassing mode up to 90 days.

Maintenance degassing
When the system is degassed, there is very little air left in the
system and it only costs money to keep the degasser active
around the clock and increases wear on the unit.
There is always some air leakage into the system that needs
to be taken care of. During maintenance degassing, the TTM
NoXygen®only runs for a few hours per day, which is sufficient
to take care of the system air leakage. The number of hours
per day needed to maintain low gas levels is shown in the table
below.

When the gas level in a system fluid is lowered, magnetite and other sediments are often
released from the inner walls of the system. These cause wear and tear on pumps and pipe
walls, among other things, and can also cause clogging of the system. TTM MAG 76 and
TTM MAG 54 effectively remove magnetite and other particles from the system fluid, which
means:
• Fewer operating interruptions. Magnetite clogs valves and other
devices and can also make wet pumps to stick together when they are shut off.
• Longer system lifetime. Magnetite and other particles have a grinding effect that
wears away at the system. The magnetite is magnetic and is attracted to the magnetic
field in pumps, where it wears away at axle seals, for example, which often results in
leakage.
• Protects the degasser. I system med hög förekomst av partiklar förhindrar TTM MAG
54/76 att avgasningsprocessen försämras på grund av igensättning av avgasaren.
The recommendation is to install TTM MAG 76 or TTM MAG 54 along with TTM NoXygen®.
It is especially important to install Mag 76 when it is known that magnetite or other particles
in the system fluid.
Installation
When installed in combination with the TTM NoXygen®degasser, the TTM MAG 54/76 is
connected to the system (½" female pipe thread) and then mounted directly on the shut-off
valve on the inlet of the TTM NoXygen®. When connecting to the TTM NoXygen®, first fit the
supplied clamping ring coupling, then connect the flat end of the TTM MAG 54/76 to the
clamping ring coupling.
TTM Offset is a Equalisation vessel used together with the TTM
NoXygen®in heating/cooling and recycling systems that are sensitive to
pressure variations e.g. pump expansion systems.
TTM Offset counters the pump expansion system turning on and
creating noise in the property’s system. It can also contribute to longer
durability in pump expansion systems, as the shutdowns do not occur
as often.
The TTM Offset is equipped with a control valve that is used as a
shut-off or drain valve when checking and adjusting the pressure
in the leveling vessel.
Installation
1. Close the shut-off valve to the system.
2. Remove the protective cover on the drain valve.
3. Open the drain valve (the spindle located on the side) and let the
water drain out.
4. Remove the black protective cover and take off the valve cap to
air valve.
5. Adjust the rubber lock pre-pressure so that this corresponds to
70-80% of the system pressure by releasing or replenishing air
through the air nipple.
6. Close the drain valve and reinstall the valve bonnet and
protective cover.
7. Reassemble the protective cover to the drain valve.
8. Open the shut-off valve to the system.

TTM MAG 54 should be inspected and cleaned regularly, at least
twice per year. The intervals depend on the quantity of particles and
magnesite in the system fluid. If you know the system fluid is very dirty,
the filter should be inspected and cleaned more often. One sign that
TTM MAG 54 requires cleaning is, for example, that TTM NoXygen®
runs for long intervals exceeding 3 minutes “pump start to pump start”
(see Operating and maintenance instructions for TTM NoXygen®).

1. Expansion vessel control
Check that the expansion tank is correctly adjusted with cor-
rect pre-pressure and that there is free expansion volume. The
TTM NoXygen®C625 requires at least 3 litres of free expansion
space. If it is suspected that the expansion space is too small,
install TTM Oset expansion vessel(art.no. 506430).
2. Pressure sensor control
Check that the "Pint" pressure on the TTM NoXygen®display
in idle mode is between minimum 0.8 bar and maximum 2.5
bar (the unit will not start if the pressure is below 0.8 bar, see
troubleshooting action 1.1). If the pressure on the display does
not match the system pressure, see troubleshooting action 7.
Also check that the "Pint" reaches at least -0.7 while the pump
is running. If not, see troubleshooting action 2.
3. Operating cycle time control
The time from pump start to pump start should not exceed the
recommendations in the table below. Long cycle times indicate
clogging of lters or ow restrictors.
See troubleshooting action 3.
4. Leakage control
Check that no uid is leaking from the blue control hose, when
the "Pint" pressure is equal to the system pressure of the plant,
in case of leakage, contact TTM. Check that no system uid
is leaking from any of the connections to the pump or vacuum
chamber.
5. Degassing capability control
When the TTM NoXygen® starts, close the shut-o valve on the
inlet and check that the "Pint" pressure reaches at least -0.7. If
not, see troubleshooting action 2. Allow the machine to stand
with the valves closed for at least 5 minutes and check that the
pressure does not change. If the pressure increases, there is a
leak, see troubleshooting action 5:3.

Check that the shut-off valves to the system are open.
Check that nothing else is blocking the flow paths.
Close the shut-off valve on the inlet and check if negative
pressure is created. If negative pressure is created,
check that there is a flow restrictor in the tank by loose-
ning the hose connection at the tank and removing the
insert. There should be three sleeves in the insert.
Clean any pre-filters and the strainer on the inlet
valve. If necessary, check the flow restrictors according
to 2.3.
Increase the set point between the solenoid valve and
the pump.
Install the Offset Equalizing vessel at the pressure
maintenance vessel, see instructions on page 2.
Install a new safety valve.
TTM NoXygen®requires 3 litres of free expansion space.
Install a TTM Offset Equalizing Vessel at the pressure
holding vessel, see instructions on page 2.
Check oxygen content. At oxygen levels below 1 mg/l, it
may take several cycles before air bubbles are released
through the vent.
Contact TTM.
Connect the control hose to a bottle of water if it is not
already connected and check that water is not being
sucked from the bottle into the TTM NoXygen®. If this is
the case, contact TTM.
Check that a vacuum is building up (at least -0.8 bar).
Check that the shut-off valves of the system are open.
Clean inlet valve filters and any pre-filters, see mainte-
nance instructions.
Contact TTM.
Cause
1:1 The system pressure is lower than 0.7 bar.
1:2 The control panel is without power.
1:3 Green LED is not lit.
1:4 Date or time is incorrectly set.
1:5 TTM NoXygen®is in maintenance mode and
start and run time settings put the unit in sleep
mode.
2:1 Air in the pump.
2:2 Flow at the outlet is obstructed.
2:3 Flow restrictor on inlet misadjusted.
3:1 See recommended operation cycle times in
the table under function check on page 10.
4:1 Set point between solenoid valve and pump is
set too narrow on the pressure retaining vessel.
4:2 There is no free expansion volume in the
system.
5:1 Fault in safety valve.
5:2 There is no free expansion volume in the
system.
6:1 The system is degassed or the gas content is
low.
6:2 The deaerator is clogged with dirt and
cannot open to release air.
6:3 The check valve on the air vent is leaking.
6:4 The degassing function is not working.
7:1 Restricted or no flow through inlet.
7:2 Pressure sensor is defective.
Issue
1. TTM NoXygen®does not
start.
2. A negative pressure is not
created in the TTM NoXygen®
(at least -0.7 bar).
3. The time between degassing
cycles is too long.
4. The systems's pressure ves-
sel works intermittently with the
TTM NoXygen®.
5. The system safety valve
releases system fluid.
6. No air bubbles comes out
of the control hose (NOTE: the
control hose needs to be placed
into a bottle of water).
7. System pressure does not
match the pressure on the
display.
