2.8 Preparations for operation
2.8.1 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.
2.8.2 Opening/closing the bypass valve
Some temperature control units are fitted with an adjustable bypass to protect fragile applications
(e.g. a glass apparatus). To find out whether your temperature control unit is equipped with an
adjustable bypass, refer to the “Wiring diagram”. → From page 85, section

The >Bypass valve< [62] is located on top of the temperature control unit. The set pressure is indi-
cated on the
>Touchscreen<
[88] in [Field 8]. The
>Bypass valve<
[62] must be fully open before the
circulation starts:
▪ at the initial filling of the machine;
▪ when switching to another thermal fluid;
▪ when switching to another application.
Opening the bypass valve:
Open the valve by turning it counterclockwise (turn 90° left as f ar as it will go).
Closing the bypass valve:
Close the valve by turning it clockwise (turn 90° right as far as it will go).
PROCEDURE

Check whether the >Bypass valve< [62] is open.

Open the >Bypass valve< [62] by turning it counterclockwise (turn 90° left as far as it will go).
2.8.3 Installing collecting container
PROCEDURE

Install a suitable hose at the >overflow< [12] on the temperature control unit (if present). The
hose must be compatible with the thermal fluid and the temperature.

Put the other end of the hose in a suitable collecting container.
