Prevent the discharge of dangerous gases and vapors
to the surrounding atmosphere. If appropriate, connect
the exhaust line to a suitable treatment system.
Check all hose connections prior to starting
operation of the cooling system.
Secure coolant hoses at the hose nozzles
(e.g., with hose clamps) to prevent their acci-
dentally slipping off.

Never block the gas outlet (hose nozzle for
tubing I.D. 3/8” (10 mm)). The exhaust hose
has always to be unobstructed and with-
out back pressure to enable an unhindered
discharge of gases and protect the pump
valves from damage.
• 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. 26).
• Ensure that the coolant outlet tubing is
always unobstructed 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 cool-
ant pressures of additional components in
the coolant circuit (e.g., coolant valve).
• Avoid overpressure in the coolant circuit
(e.g., caused by blocked or squeezed cool-
ant hoses).
