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.
2.6 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 cooler
Valid heating circulators with >Cooling coil< [29]
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 cooling 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.
