Description of the device
3.6 Residual risks
This device has been manufactured to the current state of the art. However, some
residual risk cannot be excluded.
ATTENTION
Conformity is declared by the Servimat control unit
Conformity as per the Pressure Equipment Directive (2014/68/EU) is declared
by the Servimat control unit.
• The overall conformity for the Servimat with connection to the system and
the expansion vessel must be checked and confirmed by the operator.
ATTENTION
Device damage due to exceeding of the permissible pressure and
permissible temperature
Equipment parts with a safety function in respect of water-side pressure limiting
according to the Pressure Equipment Directive 2014/68/EU and temperature
limiting according to the Pressure Equipment Directive 2014/68/EU are not
supplied.
• The operator is responsible for on-site provision of water-side pressure
and temperature protection.
CAUTION
Hot water vapour can cause burns to skin and eyes.
Hot steam can escape from the safety valve. The hot steam will cause scalding
of the skin and eyes.
• Ensure that the blow-off line of the safety valve is routed so that injuries
are not possible.
CAUTION
Risk of burns on hot surfaces
Hot surfaces in heating systems can cause burns to the skin.
• Wear protective gloves.
• Please place appropriate warning signs in the vicinity of the device.
CAUTION
Risk of injury due to pressurised liquid
If installation, disassembly 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, disassembly or maintenance work.
• Ensure that the system is de-pressurised and cooled down before
performing installation,disassemblyl or maintenance work at the
connection points.
CAUTION
Risk of injury due to heavy device weight
The device weight may cause physical injury or accidents.
• If necessary, work with a second person during assembly or
disassembly.
CAUTION
Risk of injury when 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).
4 Description of the device
4.1 Description
The Servimat is a pump-controlled pressure maintaining, make-up and degassing
station for heating and cooling water systems. The Servimat is essentially a control
unit with pump, vacuum spray pipe and at least one expansion vessel. The
expansion vessel is fitted with a membrane to divide the vessel into an air space
and a water space. preventing the ingress of atmospheric oxygen into the
expansion water.
