Disassembly
11.4 Inspection
11.4.1 Pressure-bearing components
Comply with all applicable national regulations for the operation of pressure
equipment. Before testing pressurised parts, they must first be depressurised
(see disassembly).
For vessels compliant with EN 13831, the following applies:
Material fatigue does not arise from the intended use in heating and cold water
systems (see also EN 13831 para. 6.1.8).
11.4.2 Inspection prior to commissioning
In Germany, follow the Industrial Safety Regulation
[Betriebssicherheitsverordnung] Section 15 and Section 15 (3) in particular.
11.4.3 Inspection intervals
Recommended maximum inspection intervals for operation in Germany pursuant
to Section 16 of the Industrial Safety Directive [Betriebssicherheitsverordnung]
and the classification of the device vessels in diagram 2 of the Directive
2014/68/EC, applicable in strict compliance with the Reflex Installation,
Operation and Maintenance Manual.
For vessels compliant with EN 13831, the following applies:
Material fatigue does not arise from the intended use in heating and cold water
systems (see also EN 13831 para. 6.1.8)
External inspection:
No requirement according to Annex 2, para. 4, 5.8.
Internal inspection:
Maximum interval according to Annex 2, para. 4, 5 and 6; if necessary, suitable
replacement actions are to be taken (such as wall thickness measurement and
comparison with the design specification which may be requested from the
manufacturer).
For deep-drawn vessels, no corrosion margin is provided for (EN 13831, para.
6.3.2.6.2).
Strength test:
Maximum interval according to Annex 2, para. 4, 5 and 6.
Furthermore, compliance with Section 16 of the Industrial Safety Directive and
here in particular Section 16 (1) in connection with Section 15 and in particular
Annex 2, para. 4, 6.6 and Annex 2, para. 4, 5.8, must be ensured.

The actual intervals must be specified by the operating company based on a
safety evaluation taking into consideration the actual operating conditions,
experience with the mode of operation and charging material and the applicable
national regulations for the operation of pressure equipment.

Risk of serious injury or death due to electric shock.
If live parts are touched, there is risk of life-threatening injuries.
•
•
•
Risk of burns
Escaping hot medium can cause burns.
•
•
Risk of burns on hot surfaces
Hot surfaces in heating systems can cause burns to the skin.
•
•
Risk of injury due to pressurised liquid
If installation or maintenance work is not carried out correctly, there is a risk
of burns and other injuries at the connection points, if pressurised hot water
or steam suddenly escapes.

Prior to the disassembly, shut off the "DC" degassing lines and the "WC" make-
up line from the system to the Servitec and de-pressurise the Servitec. Then
disconnect the Servitec from all voltages.
Proceed as follows:

Disassembly
DANGER
Ensure that the system is voltage-free before installing the device.
Ensure that the system is secured and cannot be reactivated by other
persons.
Ensure that installation work for the electric connection of the device is
carried out by an electrician, and in compliance with electrical
engineering regulations.
CAUTION
Maintain a sufficient distance from the escaping medium.
Wear suitable personal protective equipment (safety gloves and
goggles).
CAUTION
Wear protective gloves.
Please place appropriate warning signs in the vicinity of the device.
CAUTION
Ensure proper disassembly.
Wear suitable personal protective equipment (safety gloves and safety
goggles, for example).
Ensure that the system is de-pressurised before performing the
disassembly.
Switch the system to stop mode and secure it to prevent it being switched
back on.
Shut off the "DC" degassing lines and the "WC" make-up line.
Switch the system to a voltage-free state. Unplug the Servitec's mains plug
from the power supply.
Disconnect all cables from the terminals of the Servitec controller.
DANGER – Risk of serious injury or death due to electric shock.
Some parts of the Servitec's circuit board may still be live with 230 V even
after the device has been physically isolated from the power supply by
pulling out of the mains plug. Before you remove the covers, completely
isolate the Servitec controller from the power supply. Verify that the main
circuit board is voltage-free.
Open the "FD" drain cock at the "VT" spray tube of the Servitec until the
spray tube no longer contains any water.
If necessary, physically remove the Servitec from the system.
