For the cold condensate the discharge capacity is higher because of medium temperature and density.
2.5 Function
■Due to its gravity, the condensate flows down to the deepest point, i.e. to the condensate trap housing. A rising condensate
level lifts the float and the valve is opened through the float fork / rotary valve connection. When the condensate level drops,
the valve closes.
2.6 Compensation line
■In order to get proper function, the non-condensable gas must be able to leave the housing. Due to the vertical installation,
the non-condensable gas is able to leave the housing and flows into the steam/gas chamber above it, which has the same
pressure level. If the self-venting through the pipe must be extended, the control screw (4) can be replaced by a cutting ring
screw bolt and a compensation line can be installed leading upwards.
2.7 Automatic venting
■For the steam applications, automatic venting must be provided (vent jet or RIFOka-venting).
■RIFOka automatic venting valve: For start-up and permament venting with high venting capacity. An special liquid inside
the membrane capsule evaporates and condenses only a few degrees below the boiling point of water.

2.8 Gastight under-level float control (only for gas applications)
■For gas applications, a gastight under-level float control is nearly exclusively used. See also Operating Manual for gastight
under-level or consult with Rifox, if necessary.
When using submerged-gastight control units, please note:
The valve orifice is always under an condensate surface.
If the gas is mixed or dissolved with the condensate, there can be no separation inside the steam trap.
Small amounts of gas can separate from the condensate at the outlet.
In these cases a degassing line at the outlet towards uncritical areas (via the roof for example) may be recommended.
A horizontal inflow can calm the condensate flow and support the self-degassing to separate the gas from the condensate.
When using an angular version (EF) condensate enters from above and can also bring gas into the housing.
With an inlet from below, the degassing happen before the trap, the automatic degassing is most effective.
Traps with submerged-gastight control units should not be used at above 90°C or its use should be clarified with RIFOX in
advance.
3 Assembly
3.1 Flow Direction
■The following flow directions are possible:
Picture 5
Vario SO Vario SU Vario WR Vario WL
■Vario-WR: Flow direction horizontal from right to left
■Vario-WL: Flow direction horizontal from left to right
■Vario-SO: Flow direction vertical from top to bottom
■Vario-SU: Flow direction vertical from bottom to top
3.2 Modification for a different flow direction
The RIFOmat Vario 1222 has been delivered as Vario-SO and has to be mounted as Vario-WR.
■Unscrew the housing hexagon nuts (5) and remove the housing side part (3).
■Loosen the supporting screw (10) by unscrewing it for 1 - 2 full turns.
■Use a plastic hammer to loosen the float control assembly (7) from its conic housing seat by lightly stroking on the the
supporting screw (10) .
■Reposite the housing flange part (1) by turning it 90°.
■Reposite the float control assembly (7), so that the tube pointing vertical downwards.
■Screw in the support bolt (10) with gasket (13). Tighten it with a standard ring wrench or a open jawed wrench. Tightening
torque according to Section 6.6.
■Replace the housing gasket (2) if damaged, and mount on the housing side part (3).
■Tighten housing bolts (5) evenly crosswise. Tightening torque according to Section 6.6.
3.3 Modification for restricted space and horizontal flow
In the case of only minimal space for the housing, which projects to the side, the housing can be mounted towards to the front
or towards the rear by repositioning the housing flange part for the purpose of better maintenance or better visual inspection
of a built-on reflective water level gauge, etc.

3.4 Installation
■The condensate trap Vario 1222 has to be screwed or welded into a pipeline between flanges.
■Remove transport caps from inlet and outlet.
■Fitting direction: according to Picture 5. The condensate flow is in the direction of the arrow (note arrow on housing
flange (1) ). The housing is positioned to the side. The word TOP on the housing is at the top and must be legible horizontally.
■Supporting brackets: Ensure proper fixing of the pipeline in front of and behind the condensate trap.
■To avoid downtimes, it is recommended to install stop valves with bypass to pipeline, both in front of and behind the con-
densate trap.
4 Start-Up
The pressure build-up and heating-up of the housing should not take place abruptly. If leakage is detected after the first
inspection, the screws (4 / 5 / 6 / 10) can be fixed under consideration of the given torque moments, as given in Section
6.7. The screws can only be tightened on when the housing is unpressurized and hand warm.
5 Observation and control
The function’s failure can be observed either as condensate blockage or as gas/ steam leakage.
■Condensate blockage can be determined by a): loosen the control screw (4) for a quarter rotation, while no condensate
leakage should occur; and by b): a surface thermometer on the housing for steam applications (if necessary, consult with
Rifox).
■Gas / steam leakage: can be determined by an ultrasonic measuring device, and for steam applications by a surface
thermometer. In case of steam leakage, open the condensate trap according to Section 6.1. Make sure that float can be easily
moved. If necessary, disassemble and clean the float control assembly. If damages/ wears are detected on parts or on the
sealing surface, the complete float control assembly should be replaced.
6 Maintenance / Inspection
6.1 Opening the condensate trap and dismantling the float control assembly
■The steam trap can not be dismantled from the pipeline system.
■The condensate trap must be depressurized. Shut off the system before and after the condensate trap.
■Release any remaining pressure by loosening the control screw (4) by only a quarter turn.
■Loosen the housing screw (5) evenly crosswise and take off housing side part (3).
■Unscrew the supporting screw (10) for 1-2 turns.
■With a few light strokes using plastic hammer on the front side of the supporing screw (10) to loosen the float control
assembly (7) from its conic housing seat.
■Screw out the supporting screw (10) completely. Remove the float control assembly (7).
6.2 Disassembling, cleaning and assembling the float control (Picture 6)
■After removing the cotter pin (p), the rotary valve (v) can be simply pulled out to
the side.
■Clean the parts using, for example, benzine.
■Check the rotary valve (v) for wear along the sealing edge. If wear is detected, the
support body (b) and the rotary valve (v) must be replaced. A thorough leakage test
must be carried out by Rifox.
■During assembling ensure that the notch in the rotary valve (v) points to the punch
mark on the support body (b) and the cotter pin (p) is inserted and secured again
carefully.
■The float must be able to be moved up and down by hand easily.

Replace the capsule (10.3) as additional equipment.
■Dismantle the complete float control assembly (7) as described in Section 6.1.
■Loosen the hexagon nut (10.5) with wrench size 19.
■Screw up the support frame (10.4) for approx. 5 mm by turning it counterclockwise.
■Dismantle the capsule (10.3).
■Visual check the seat part of valve gate (10) and of capsule (10.3) for wear (cross
scoring).
■Replace the capsule (10.3). Marking S: down to 8 °C condensate supercooling.
■Screw support frame (10.4) against the capsule (10.3) using minimal manual force
and align such that the support frame (10.4) is positioned precisely in the crosswise.
■Hold support frame (10.4) in this position and lock hexagon nut (10.5) moderately.
■Install the float control assembly (7) as described in Section 6.3.
6.5 Care and maintenance
■In the case of a great risk of dirt accumulation, the housing, when it is depressurized, should be rinsed thoroughly from
time to time. If necessary, the float control assembly (7) should also be checked according to Section 6.2.
■The dirt, which has been accumulated in the housing, can be removed away by screwing off the screw plug (6).
■For special applications, it is advisable to install a separate upstream strainer.
■The float control assembly (7) usually does not to be special maintained. The maintenance depends primarily on the wear
resistance of the valve gasket. See Section 6.1 and 6.2.
