CAUTION
Personal injury and damage to property due to overpressure!
By closing the two ball valves in the primary circuit, the safety group is separated
from the heat exchanger. A rise in temperature in the storage tank causes high
pressures which can result in personal injury or damage to property!
Only close the ball valves for service and maintenance.
When closing the ball valves in case of servicing, also put the pumps
out of operation and close the piston valves of 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 get 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 lubricant based on silicone or polyalkylene and free of mineral oils, such as
Unisilikon L250L and Syntheso Glep 1 of the Klüber company or a silicone spray.
