CAUTION
Risk of burns!
The valves and fittings and the pumps can become heated up to more than
100 °C during operation.
The shell must remain closed during operation.
CAUTION
Personal injury and damage to property due to overpressure!
By closing the two ball valves in the primary circuit you isolate the pressure relief
valve from the heat exchanger. A rise in temperature in the storage tank will
cause high pressures and could result in personal injury or damage to property!
Only close the ball valves for service and maintenance.
If you close the ball valves in case of servicing, do also put the pumps out
of operation and close the ball valves in the secondary circuit.
NOTICE
Material damage due to mineral oils!
Mineral oil products cause lasting damage to seals made of EPDM, whereby the sealant
properties are lost. We do not assume liability nor provide warranty for damage to property
resulting from sealants damaged in this way.
It is imperative to avoid that EPDM gets in contact with substances containing mineral
oils.
Use a silicone- or polyalkylene-based lubricant free of mineral oil such as Unisilikon
L250L and Syntheso Glep 1 from Klüber or a silicone spray.
