• Only install the optional coolant valve in the
supply line of the exhaust waste vapor con-
denser.
• Note: Install the hoses of the cooling system
in a way to avoid the flow / dripping of con-
densed water onto the pumping unit (espe-
cially cables and electronic parts, see also
IP degree of protection, „Technical data“,
pg. 25).
• Ensure that the coolant outlet tubing is always unob-
structed and that it cannot get blocked.
• Maximum permissible coolant pressure at the exhaust
waste vapor condenser: 87 psi (6 bar) absolute. Outlet
flow must always be unhindered.
• Comply with the maximum permissible coolant pres-
sures of additional components in the coolant circuit
(e.g., coolant valve).
• Avoid overpressure in the coolant circuit (e.g., caused
by blocked or squeezed coolant hoses).
