Variomat Touch — 09.2020 - Rev. A
11. Switch on the main switch.
12. Activate the make-up.
13. Switch to Automatic mode.
– Depending on the filling level and pressure, the "PU" pump and the
automatic make-up will be switched on.
14. Slowly open the cap valves upstream of the tanks and secure them against
unintended closing.
Checking Insufficient water "Off"
15. Check the displayed value for the Insufficient water "OFF" filling level
message.
– Insufficient water "Off" is displayed at the controller at a minimum
filling level of 7 %.
Checking Make-up "Off"
16. If necessary, check the make-up value displayed at the controller.
– Automatic make-up is deactivated at a level display of 25 %.
Maintenance is completed.
Note!
If automatic make-up is not connected, you must manually fill the tanks
with water to the recorded filling level.
Note!
The setting values for pressure maintenance, filling levels and make-up
are provided in the chapter Standard settings, see chapter 10.3.3
"Default settings" on page 20 .
11.3 Inspection
11.3.1 Pressure-bearing components
Comply with all applicable national regulations for the operation of pressure
equipment. De-pressurise all pressurised components prior to inspection (see
disassembly information).
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 Regulation [Betriebssicherheitsverordnung]
and the vessel classification of the device in diagram 2 of the Directive
2014/68/EC, applicable in strict compliance with the Reflex Installation,
Operation and Maintenance Manual.
External inspection:
No requirement according to Annex 2, Section 4, 5.8.
Internal inspection:
Maximum interval according to Annex 2, Section 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).
Strength test:
Maximum interval according to Annex 2, Section 4, 5 and 6.
Furthermore, compliance with Section 16 of the Industrial Safety Regulation and
Section 16 (1) in particular, in conjunction with Annex 2, Section 4, 6.6 and
Annex 2, Section 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
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 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.
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).
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.
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.
• Ensure that the system is de-pressurised before performing the
disassembly.
• Prior to dismantling, block off all "water"-side connections to the device.
• Vent the device to de-pressurise it.
1. Disconnect the system from the power supply and secure it against
unintended reactivation.
2. Disconnect the power cable of the device from the power supply.
3. Disconnect all cables from the terminals of the device control unit and
remove them.
DANGER – Risk of serious injury or death due to electric shock.
Some parts of the device's circuit board may still carry 230 V voltage even
with the device physically isolated from the power supply. Before you
remove the covers, completely isolate the device controller from the power
supply. Verify that the main circuit board is voltage-free.
4. Disconnect the secondary tank (if provided) on the water side from the
system and the primary tank.
5. Open the "FD" feed and drain cocks at the tanks until they are completely
empty and de-pressurised.
6. Undo all hose and pipe connections to the tanks and the control unit of the
device to the system and remove them completely.
7. If necessary, remove the tanks and the control unit from the system area.
