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).
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 Acces-
sories.

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.
