Switched off temperature control unit installed outdoors with water as thermal fluid
MECHANICAL DAMAGE CAUSED BY WATER FREEZING IN THE TEMPERATURE CONTROL UNIT

The temperature control process must be permanently switched on.

Only switch off the temperature control unit permanently at ambient temperatures below the
freezing point if the temperature control unit was completely discharged.
At temperatures below dew point, the temperature control unit is turned off and on again.
MATERIAL DAMAGE CAUSED BY SHORT CIRCUITS AS A RESULT OF CONDENSATION IN THE ELEC-
TRICAL CABINET

At ambient temperatures below dew point, leave the temperature control unit permanently turned on.

If the temperature control unit is turned off at ambient temperatures below dew point: Check
the interior of the electrical cabinet for condensation formation. Turn on the temperature con-
trol unit only after the condensate was removed.
The temperature control unit is switched on with a snow load on the unit or an ice-covered fan
DAMAGE TO THE TEMPERATURE CONTROL UNIT

Do not switch on the temperature control unit with a snow load on the unit or an ice-covered fan.

Remove the snow from the unit before switching on the temperature control unit.

Check the fan for freedom of movement before switching on the temperature control unit.
A heater and a fan are installed in the electrical cabinet of the temperature control unit for out-
door installation. This will prevent the formation of condensation in the electrical cabinet. If the
temperature control unit is turned off at an ambient temperature below dew point, the tempera-
ture difference between electrical cabinet and surrounding area cannot be compensated by the
heater/fan. This results in the formation of condensation inside the electrical cabinet. A short
circuit occurs in the electrical cabinet if the temperature control unit is then turned on again.
Applicable for models designed for winter operation and outdoor installations!
To operate the temperature control unit within a laboratory or office, the temperature control unit
is equipped with a remote control option. On the side of the temperature control unit is an opening
for the extension cable between “Unistat Control ONE” and “Pilot ONE”. Likewise, lines for the op-
tional Com.G@te, external temperature sensor, etc. can be routed through this opening.
The responsible body must install a drip tray below the temperature control unit. The use of a drain tray
may be prescribed by national law for the installation area of the temperature control unit (including
accessories). The responsible body must check and apply the applicable national regulations.
2.10 Preparations for operation
2.10.1 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.
