Maintenance
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, removal 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 hot steam suddenly escapes.
•
Ensure proper installation, removal or maintenance work.
•
Ensure that the system is de-pressurised before performing installation,
removal or maintenance work at the connection points.
The ’Servitec’ must be serviced annually or after 16,000 degassing intervals,
whichever comes first.
Note!
Shorter maintenance intervals are required if the default setting for
interval degassing of 8 degassing cycles and 12 h idling time exceeds
the following times for continuous degassing:
•
Continuous degassing time of about 14 days
or
•
Continuous degassing time of 7 days + 1 year interval degassing
with default setting.
The maintenance intervals depend on the operating conditions and the
degassing times.
The annual maintenance is displayed upon expiry of the set operating time. Use
"Quit" to acknowledge the "Maintenance recommended" message.
Note!
Maintenance work must be carried out and confirmed by specialist
personnel or the Reflex Customer Service.
