11.3 Inspection
11.3.1 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).
11.3.2 Inspection prior to commissioning
In Germany, follow the Industrial Safety Regulation
[Betriebssicherheitsverordnung] Section 15 and Section 15 (3) in particular.
11.3.3 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.
12 Disassembly
DANGER
Risk of serious injury or death due to electric shock.
If live parts are touched, there is risk of life-threatening injuries.
•
Ensure that the supply cable to the device is disconnected and secured
against being switched back on.
•
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 locally
applicable electrical engineering regulations.
CAUTION
Risk of burns
Escaping hot medium can cause burns.
•
Maintain a sufficient distance from the escaping medium.
•
Wear suitable personal protective equipment (safety gloves and
goggles).
CAUTION
Risk of burns on hot surfaces
Hot surfaces in heating systems can cause burns to the skin.
•
Wait until hot surfaces have cooled down or wear protective safety
gloves.
•
The operating authority is required to place appropriate warning signs in
the vicinity of the device.
CAUTION
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.
•
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.
•
Close both ball valves before disassembly.
•
De-pressurise the device by venting it.
1. Disconnect the system from the power supply and secure it against
unintended reactivation.
2. Disconnect the power plug of the device from the voltage supply.
3. Disconnect and remove cables routed from the system to the device
controller.
4. Disconnect the expansion vessel (MAG) (if provided) on the water side from
the system and the hot water storage tank.
5. Open the feed and drain cocks. until the device is completely empty and de-
pressurised.
6. Undo all pipe connections to the system and remove them completely. Pay
attention to residual water levels in the system.
7. If necessary, remove the Reflex Hydroflow mains water station from the
system area.
