V2.0.0en/09.06.16//15.09 Unistat®
2.5 Installation conditions
Temperature control unit is connected to the power supply line
DEATH FROM ELECTRICAL SHOCK BY DAMAGE TO THE POWER CABLE.
Do not put temperature control unit on power cable.
Operating the temperature control unit fitted with castors without brakes activated
CRUSHING OF LIMBS
Activate brakes on the wheels.
▪ Allow the temperature control unit to acclimate for about 2 hours when changing from a cold to a
warm environment (or vice versa). Do not turn on the temperature control unit before!
▪ Install upright, stable and without tilt.
▪ Use a non-combustible, sealed subsurface.
▪ Keep environment clean: Prevent slip and trip hazards.
▪ Wheels must be locked after the installation, if installed!
▪ Spilled/leaked thermofluid must be disposed of immediately and properly. Follow the instructions
on page 16, section »Proper disposal of resources and consumables« for the disposal of ther-
mofluid and material.
▪ Observe the floor load bearing capacity for large units.
▪ Observe the ambient conditions.
2.6 Temperature control unit for outdoor installation incl. winter
operation
Shut down temperature control unit with water cooling in outdoor operation
MECHANICAL DAMAGE CAUSED BY WATER FREEZING IN THE COOLING WATER LINE
Leave the >Mains isolator< [36] permanently in the “ON” position.
Only switch off the temperature control unit permanently via the >Mains isolator< [36] if the
temperature control unit was separated from the cooling water circuit and discharged at ambi-
ent temperatures below 0 °C.
At temperatures below 20 °C, the temperature control unit is turned off and on again.
MATERIAL DAMAGE CAUSED BY SHORT CIRCUITS AS A RESULT OF CONDENSATION IN THE CABI-
NET
Leave the >Mains isolator< [36] permanently in the “ON” position in case of ambient tempera-
tures below 20 °C.
If the temperature control unit is turned off at ambient temperatures below 20 °C:
Check the interior of the electrical cabinet for condensation. Turn the temperature control unit
on via the >Mains isolator< [36] only when the condensate was removed.
A heater and a fan are installed in the electrical cabinet of the temperature control for outdoor
installation. This prevents the formation of condensation in the electrical cabinet. If the tempera-
ture control unit is turned off at an ambient temperature below 20 °C via the >Mains isolator<
[36], the temperature difference between electrical cabinet and surrounding area cannot be com-
pensated by the heater/fan. It results in the formation of condensation inside the electrical cabi-
net. If the temperature control unit is then switched on via the >Mains isolator< [36], a short
circuit occurs in the electrical cabinet.
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.
