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.
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 Preparations for operation
2.7.1 Unscrewing/activating the leveling feet (if any)
The leveling feet are not unscrewed/activated before switching on the temperature control unit
DEATH OR SERIOUS INJURY DUE TO CRUSHING

The parking brakes must be activated at the casters (if any) and/or the leveling feet must be
unscrewed/activated before the temperature control unit is put into operation.

The temperature control unit may move if the parking brakes of the casters (if any) are not
activated and/or the leveling feet are not unscrewed/activated.
Always unscrew/activate the leveling feet before switching on the temperature control unit.
Uneven floors can be compensated by adjusting these leveling feet.
PROCEDURE

Verify that the parking brakes of the casters (if any) have been activated.

Unscrew the leveling feet.

Compensate uneven floors by adjusting these leveling feet, if necessary. Use a spirit level to
horizontally align the temperature control unit.

Tighten the lock screws on the leveling feet after aligning the temperature control unit. This
prevents the leveling feet from changing their height during operation.
