10.1.5 Connection to the cooling system

• ThecoolingowmustalwaysbestartedbeforestartingtheCOMBIVERT.
The connection to the cooling system can occur as closed or open cooling circuit. The
connection to a closed cycle cooling circuit is recommended, because the danger of
contamination of coolant is very small. Preferably also a monitoring of the pH value of
the coolant should be installed.
Pay attention to a corresponding conductor cross-section at required equipotential
bonding in order to avoid electro-chemical procedures.
Otherelementsinthecoolingcircuitsuchaspumps,mixingvalves,shut-ovalves,ven-
tilation etc. must be attached according to the cooling system and the local conditions.
NOTICE
A discontinuous mode is not recommended, since this leads to a reduc-
tion of the service life.
