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 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
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.
• Ensure that the system is de-pressurised before performing the disassembly.
CAUTION
Risk of injury upon coming into contact with glycol containing water
Contact with glycol containing water in plant systems for cooling circuits can result in irritation of the skin and eyes.
–
Use personal protective equipment (safety clothing, gloves and goggles, for example).
Prior to disassembly, shut off the degassing pipes from the system to the device and de-pressurise the device. Then disconnect the device from all
electrical power sources.
Proceed as follows:
1.
Set the device controller to stop mode.
2. Close the connections from the device for the degassing pipes.
3. Disconnect the device from all electrical power sources.
4. Disconnect the power cable of the device from the power supply.
5. Secure the plant system to prevent it being switched back on.
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.
6. Remove the degassing pipes from the device.
–
Ensure that the device shut-offs are not twisted when you remove the pipes.
– Slowly disconnect the pipes and if necessary catch any escaping residual water in a container.
7. Physically remove the device from the system.
8. Drain all residual water from the device.
–
At the device, open the connections for the degassing pipes.
– Use a suitable container to catch the residual water.
The device is removed.
