Recommended temperature control and cooling water hoses
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).
Hot or cold thermal fluid and surfaces
BURNS TO LIMBS
Avoid direct contact with the thermal fluids or the surfaces.
Wear your personnel protective equipment (e.g. temperature-resistant safety gloves, safety
goggles, safety footwear).
Uncontrolled formation of ice at the connections and hoses of the thermal fluid circuit
SLIP AND TRIP HAZARD
If the temperature is controlled in the minus range, ice forms at the hoses and connections of
the thermal fluid circuit. This occurs by condensing and freezing of atmospheric humidity.
Check the strength of the ice formation. If too much ice is formed, this increases the risk of the tempera-
ture control unit tipping over. Secure the temperature control unit against tipping if this is the case.
Check the ground below the ice formation for condensation water. Collect the condensation
water with a suitable container or thoroughly remove it at regular intervals. You thus prevent
the danger of slipping caused by condensation.
To connect applications, use only temperature control hoses that are compatible with the thermal
fluid used. When selecting temperature control hoses, also pay attention to the temperature range
in which the hoses are to be used.
▪
We recommend you use only temperature-insulated temperature control hoses with your tem-
perature control unit. The responsible body is responsible for the insulation of connection valves.
▪
We
exclusively
recommend reinforced hoses for connecting to the cooling water supply. Cooling water and
insulated temperature control hoses can be found in the Huber catalogue under Accessories.

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 maximum 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.
