Wrench sizes and torques
Note the wrench sizes that result for the pump connection on the temperature control unit. The
following table lists the pump connections and the resulting wrench sizes, and torque values. A leak
test must always be performed, and the connections tightened if necessary. The values of the max-
imum torque (see table) must
not
be exceeded.

G-thread (flat-
sealing)
Adapt the torque to the material of the flat seal used. First hand-tighten the temperature
control hose.
When using adapters, do not overtighten the G-thread on the pump connection when
connecting a temperature control hose. When connecting a temperature control hose to
the adapter piece, secure the G thread against overwinding.
2.7
Temperature control units with water cooling
Open electrical wires below the temperature control unit if the temperature falls below the dew
point.
DEATH FROM ELECTRICAL SHOCK BY WATER ENTRY INTO THE ELECTRIC LINES.
A temperature below the dew point may result in condensation in the temperature control unit
and at the cooling water connections. The condensation is caused by high humidity at the cool-
ing water-bearing components. The condensation exists the temperature control unit at the
bottom.
Electrical lines directly below the temperature control unit must be protected against liquid
ingress.
Use of unsuitable/defective hoses and/or hose connections
INJURIES
Thermal fluid
Use appropriate hoses and/or hose connections.
Check periodically for leaks and the quality of the hose and hose connections and take suitable
measures (replace) as required.
Isolate and protect temperature control hoses against contact/mechanical load.
Cooling water
Reinforced hoses must be used to satisfy tougher safety requirements.
Shut off the cooling water supply to the temperature control unit even for shorter downtimes
(e.g. overnight).
No protection against corrosion
DAMAGE TO THE TEMPERATURE CONTROL UNIT
The addition of anti-corrosion agents is mandatory if salts (chlorides, bromide) have been
added to the water circuit.
Ensure that the materials used in the cooling water circuit are resistant with respect to the
cooling water. See the data sheet from page 81 in section
for information on the ma-
terials used.
Take suitable measures to maintain the warranty conditions.
