Installation, operating and maintenance instructions
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
•
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 9.
•
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 7 and 8.
Systems using expansion vessels and pressurised expansion vessels
When operating TTM NoXygen
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
opertation cycles. A surge vessel measuring 60 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
An initial inspection is therefore recommended after only 24 hours of operation

C625 unit.

IMPORTANT!
C625, there must be 3 litres of free expansion volume in the system.
®
can result in the system pressure falling very quickly.
®
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.
System pressure
System pressure = system height (m) + 5 m.
Example
System height = 5m + 5m => 1 bar of system pressure
