Start-up
Setting up the temperature control unit
The temperature control unit is designed for an ambient temperature
range of 10-40 °C. Sufficient ventilation must be provided during setup.
The distance between the devices and/or between the temperature con-
trol unit and a wall must be at least 10 cm. The ventilation slits must not
be covered.
Check the temperature control unit to ensure that it is undam-
aged and complete
Do not tip the temperature control unit! Heat transfer medium
remaining in the unit from the test run could spill, and there is a
risk that the thermal insulation could become soaked with the flu-
id (medium)
Position the temperature control unit on a horizontal surface and
engage the wheel brake
WARNING
The temperature control unit may be pressurised - Danger of injury in the event
of escaping hot water or steam.
Never start up the temperature control unit without the side panels and hous-
ing.
Never use the temperature control unit in potentially explosive environments
and protect it against sprays and cleaning agents that contain solvents.
Any leaks in the temperature control circuit (temperature control unit, connect-
ing lines, consumers, etc.) must be repaired immediately.
Observe local laws during set-up.
CAUTION
Before detaching connecting lines in the temperature control circuit, the tem-
perature control unit must first be allowed to cool down. The cooling time will
depend on the outlet temperature. The shutdown procedure is initiated by
pressing the ON/OFF button. The pump continues to run. The temperature con-
trol unit cools down until the temperature of the heat transfer medium has
reached the programmed coastdown temperature (factory default 60 °C). The
pump and the control system are then switched off!
Check that the pump is no longer running and that the system pressure gauge
reads 0 bar (display on the screen reads OFF)!
The corresponding chapters of the Operating Instructions must be read before
starting up the temperature control unit!
Operating Instructions
The Operating Instructions for the temperature control unit must be kept
at all times close at hand for the personnel responsible for start-up and
operation. Please ensure that the operating instructions are read. By do-
