Troubleshooting
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.
8. Red led diod ligths up/flashing

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 9.
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.
8.1 An alarm is active
Solution
Raise the system pressure to at least 0.8 bar.
Check that there is voltage to the TTM NoXygen
Check that the TTM NoXygen
is in operating mode.
®
Press twice, then enter.
Check and change settings if necessary.
If necessary, change start time Tstart and/or operating
time "Toperat" or change time and date settings.
Ventilate the pump. NOTE It may take up to 10 minutes
for the pump to vent itself.
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,
remove the front shroud and adjust the balancing valve
by closing and opening it a couple of times. 1.8 is the
default value for the balancing valve.
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 6 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
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.
See alarm list on page 6.
