’servitec’ is a deaeration and make-up station mainly consisting of a control unit and a vacuum spray-tube.
The attached conformity certification certifies the compliance with the directive 97/23/EC for pressure devices and 89/336/EC
on the electromagnetic compatibility.
Installation, operation, pre-operation test, periodic inspections
according to the governing local regulations. The installation and the operation to be performed to the state of the art by
skilled installation technicians and specially trained personnel. An approved inspection body must be notified of necessary
tests before operation (only for ’servitec’ special systems, PS x V > 50 bar x litre) and after major changes in the installation,
as well as of periodic inspections. For recommended inspection intervals, see section “Periodic Inspection”. Only vacuum
spray-tubes without visible external damage to the pressure body may be installed and operated.
The operator is obliged to read thoroughly the installation, operating and instruction manual before installation/
initial start-up, to follow the instructions and to confirm the expert installation and start-up in the installation and
start-up certificate (→ p. 25). This is a warranty requirement. We recommend having the initial start-up and annual
maintenance performed by your Reflex Service (→ p. 21).
Attention! ’servitec’ is for the stationary, not for the mobile operation. The set warranty periods are only applicable if a
maximum of 16.000 deaeration intervals per year is observed (→ maintenance p. 20).
Changes to the ’servitec’,
for instance welding operations on the spray-tube or interventions into the wiring are not permissible.
Adherence to the parameters
Details concerning manufacturer, year of manufacture, serial number and the technical data are provided on the name plate.
Suitable safety measures for temperature and pressure protection in the supply unit must be taken to ensure the specified
permissible maximum and minimum operating parameters (pressure, temperature) are adhered to. Use only in systems with
non-toxic waters.
Thermal protection
In water heating systems, a warning instruction must be provided by the operator near the vacuum spray-tube if persons are
at risk from excessive surface temperatures or a suitable thermal insulation. Careful when working on a hot system. There is
a scalding hazard from water issuing especially from the screw connections, the bleed screw for the pump and the dipstick
tube-deaeration unit and injury hazard through high temperatures when touching especially the vacuum spray-tube.
Electrical connection
The electrical wiring and connection must be performed by a qualified electrician according to the applicable local EVU and
VDE regulations. De-energise the system before working on electrical components.
Failure to heed these instructions especially the safety instructions can result in the destruction of and defects of the ’servitec’,
endanger persons and impair operation. Any claims for warranty and liability are excluded if these instructions are violated.

reflex ’servitec’
Installation
Preferably install ’servitec’ on the
system side so that the temperature
exposure remains ≤ 70 °C.
When using softening systems, this
should be installed between ’fillset’
and ’servitec’.
If the shut-off at the connection point
of ’servitec’ is closed when shutting
down the circulating pumps, part flow
deaeration remains operational.
Notes to the installer:
reflex ’servitec magcontrol’ in a multiple boiler
system with hydraulic points and expansion vessel
The combination ’servitec’ with com-
pressor-controlled pressure-maintai-
ning stations (e.g. ’reflexomat’) is
especially recommended. The system,
which was highly degassed by the
’servitec’, is softly cushioned by the
’reflexomat’.
The water level in the expansion ves-
sel is monitored by the control unit of
the pressure maintaining station. The
230 V make-up signal LS of the
pressure maintaining station triggers
the make-up process with deaeration.
Optimum deaeration operation is en-
sured by connecting ’servitec’ in the
main circuit water flow.
On combining pump-controlled pre-
ssure maintaining stations with ’ser-
vitec’, we always recommend indivi-
dual boiler protection with a diaphragm
pressure expansion vessel
(e.g. ’reflex’).
Notes to the installer:
reflex ’servitec levelcontrol’ and compressor
pressure maintenance - an ideal combination
reflex ’servitec’ deaeration stations solve „gas problems“ in three ways:
no direct drawing in of air through controlled pressure maintenance
no circulation problems through free bubbles in the circuit water
reduction of corrosion risk through oxygen withdrawal from the filling and make-up water
* Detail connection → p. 7
The circuits must be adjusted to suit local conditions.

Automatic mode may only be activated after completed initial start-up. If the system is in
automatic mode, you can select from three deaeration programs if required. System cont-
rol is active with all three deaeration programs. Make-up takes place automatically.
Select from the customer menu (→ p. 16)
Permanent deaeration – Intensive deaeration after start-up and repairs
The deaeration cycles for the set continuous deaeration time (24 hours basic setting)
will be executed successively. The control will then proceed with intermittent degas-
sing automatically. On start-up, at least half of the system volume in the case of water
systems should flow at least once by way of the ’servitec’, in the case of water/glycol
mixtures, 5 times the system volume.
Interval deaeration – Economy mode in automatic mode
After 8 cycles (standard), a break (standard 12 hours) is observed before the next 8
deaeration cycles are started. This program is started automatically after the expiry of
continuous deaeration or can be selected manually with systems already degassed.
Interval deaeration will start at 08h00 each day.
Make-up deaeration – Only deaerating the make-up water
The system water will not be degassed. This operating mode is practical in summer
mode (→ p. 18) or if general deaeration of the system water is not required.
Manual mode is required for hydraulic balancing of the pressure reducing valves (5, 8)
and the overflow valve (3) and for filling systems. There are two types of operation in
manual mode: NE (make-up deaeration) and SE (system deaeration).
System deaeration SE – system water is degassed
System deaeration is active while is flashing.
Acknowledge system deaeration
The deaeration cycles (→ above) are successively executed in this type of operation.
The system deaeration is required for hydraulic balancing of the pressure reducing
valve (8) and the overflow valve (3) (→ p. 12). The maximum running period is
displayed at the bottom right. After expiry of this time, the ’servitec’ moves into error.
An error message will be output if the operating pressure falls below the minimum.
Make-up deaeration NE – make-up water is degassed
Make-up deaeration in manual mode is active for as long
as is flashing.
Acknowledge make-up deaeration
This type of operation primarily serves for hydraulic balancing of the pressure-reducing
valve (5) (→ p. 12). However, with ’servitec magcontrol’ it is also possible to fill the sys-
tem. The filling time (with contact water meter also the filling quantity) will be monito-
red. Once the filling pressure (pF, → p. 10) or the filling time (10 h) has been reached,
make-up deaeration is terminated and an error message output.
Again press the button to get to stop mode.
In stop mode 'servitec' is not operational except for the display. Operation monitoring
does not take place. All pumps or solenoid valves are switched off. The adjacent display
appears when the „stop“ button is pressed.
If the stop mode has been activated for longer than 4 hours, a message will be
initiated.

Operation

The following information is announced by way of this interface:
– Continuous information concerning pressure
– Information on the pump operating status (only ’servitec magcontrol’)
– Information of the operating status of the solenoid valve for make-up
– Information on the added value of the contact water meter
– Information on all messages
– Information from the error memory
Connection of the interface with the primary control centre or similar
– The interface is arranged on the display board in the switching cabinet door in the lower left corner. A four-pin
plug (plug-type LP terminal, grid 3.81 mm, 4-pin, type 8813B/04OB) is required for connecting the interface.
The plug can be obtained from the Reflex service.
– Connect the interface with a screened cable twisted or stranded together in pairs, e.g. LJYCY (TP), 4 x 2 x 0.8
(max. total bus length = 1000 m)
– When using a control centre or similar not equipped with an interface RS-485 but with an interface RS-232,
an appropriate interface converter is required.
– When using the communication module (optional) the interface is occupied by connecting the
communication module.
The protocol of the interface RS-485 can be requested from reflex service if required.
Interface RS-485
Summer operation
If the circulating pumps of the system are taken out of service during summer, deaeration of the mains content water
can only be safeguarded if the shut-off between overflow line and pump line of the ’servitec’ is closed. If this cannot be
ensured, the deaeration program should be set to make-up deaeration by way of the customer menu (→ p. 16).
If the ’servitec’ was operated in the operating type make-up deaeration during summer, it should be reset to intermittent deae-
ration or, if desired, to continuous deaeration after the circulating pumps have been switched on again.
Sticking of the pump (10) is avoided through the positive start (24 h). Sticking of the pump cannot be excluded after prolonged
disuse (’servitec’ de-energised or in stop mode). For this reason the pump rotor should be turned with the screwdriver prior to
restarting.
Standard settings
Parameters have been reset in the data memory of the ’servitec’ which are based on research and operating experience.

Operation
Active messages are displayed in the message line of the display. In addition to this the error LED lights up (red). The dry
operation protection is signalled directly by a separate LED (→ p. 4). If several messages are active simultaneously, these
can be directly displayed with .
Most of the messages automatically acknowledge themselves once the cause has been remedied. Errors such as „make-up
time 06“ or „make-up cycle 07“ must be acknowledged manually.
An error and parameter memory is available for subsequent analysis (→ p. 16). For remote transmission it is possible to use
the floating changer for the aggregate message, the floating contact for the dry operation protection and the RS-485 inter-
face (→ p. 17). In the customer menu (→ p. 16) it is possible to select whether only the messages characterised as alarms
or all messages will pass through the floating output.

Maintenance
Caution! Observe general safety instructions (→ p. 5)!
The ’servitec’ must be maintained annually, but at least after 16.000 deaeration cycles (this corresponds to a continuous dea-
eration time of approximately 14 days or a continuous deaeration time of 7 days + 1 year intermittent deaeration with standard
setting). Maintenance operations may only be performed by specialists. We always recommend that you commission your
Reflex service.
To remind of the maintenance to be performed at least annually, the display "maintenance recommended" appears after expiry
of the set operating time, which can be acknowledged with the „quit“ button.
When carrying out maintenance operations on the vacuum spray-tube proper, this should first be depressurised by way of the
filling and drain cock (21).

– Following the expiry of the push-out time (50 s) the pump (10) starts;
vacuum is drawn, can be read off the vacuum gauge (21)
– Pump (10) switches off (after 30 seconds or 20 seconds with gl),
water deficiency LED may not light up
– Version gl solenoid valve (7) opens when the pump is switched off
– Water is sprayed in by way of the pressure connection with nozzle (22),
vacuum is broken, gas is expelled,
gas must be expelled before the next cycle can commence
Make-up deaeration
– Start make-up deaeration (NE, flashes)
– Solenoid valve (4) of the make-up opens, the pump starts after
50 seconds and draws vacuum
– Pump switches off (30 seconds or 20 seconds)
– Water continues to be sprayed in via nozzle (22), vacuum is broken,
gas is expelled,
gas must be expelled before the next cycle can commence.
– Deactivate make-up deaeration (NE, no longer flashes)
Note:
Once the gas has been completely expelled through the dipstick tube-deaeration unit and the
water deficiency LED (red) has not come on during the injection process, maintenance is complete.
