splinters in case of breakage, acts as ther-
mal isolation to avoid condensation of hu-
midity and is intended to absorb shocks.
➨
Attach the tubing of the coolant circuit to the respective
hose nozzles (hose nozzles for tubing I.D. 1/4”-5/16”
(6-8 mm), see image) at the waste vapor condenser.
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 accidentally slipping off.
➨
Prevent the discharge of dangerous gases and vapors
to the surrounding atmosphere. If appropriate, connect
the exhaust line to a suitable treatment system.
+
Never block the gas outlet ((8) hose nozzle for tubing
I.D. 3/8” (10 mm)). The exhaust hose has always to be
unobstructed and without back pressure to enable an
unhindered discharge of gases and protect the pump
valves from damage.
• Note: Install the hoses of the cooling system in a way
to avoid the flow / dripping of condensed water onto the
pumping unit (especially cables and electronic parts,
see also IP degree of protection, “Technical data”, pg.
26.
• 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).
• Only install the optional coolant valve in the supply line
of the exhaust waste vapor condenser.
