9 Start-up

Only qualified staff may start up an appliance, a group
of appliances, or the external unit by agreement with
the operator.
This work must be conducted according to the
VENTO system commissioning instructions.
These instructions are available from qualified staff.
The appliance may only be started up in the intended
installation room and after checking for completeness.
WARNING
Danger from carry-over of leaked flam-
mable refrigerant into drains.
Accumulation of refrigerant can create an explo-
sive gas/air mixture.
Fire hazard.
Prior to start-up and restarting, fill the drain with
approx. 2 litres (0.5 gallons) of water (H2O).
Prevents carry-over of refrigerant into drains.
Damage to the electrical system and/or
the refrigerant circuit.
Contact with live parts may result in electric
shock. Flammable refrigerant can escape and
cause an explosive gas/air mixture. Fire haz-
ard due to sparking or overload.
▪ Do not operate a damaged appliance.
▪ Do not connect a damaged appliance or
damaged parts (such as connecting ca-
bles) to the power supply.
▪ Only qualified staff may replace damaged
parts, e.g. connecting cables.
▪ Observe safety notices and warnings for
appliances with flammable refrigerants
(see →Flammable refrigerants).
▪ In the event of damage to the appliance,
promptly contact the maintenance service
(see → Maintenance services).
NOTICE
Property damage due to incorrect ambient
conditions.
▪ Adjust the appliance to match the ambient temper-
ature prior to start-up.
▪ The ambient temperature must not fall below 16°C
(60.8°F).
Material and property damage due to incor-
rect commissioning.
▪ Requirements before applying the operating voltage:
–
Defrosting water drain must be available (see
→ Setup and installation).
–
For appliances with a brine circuit, the waste
heat system must be in operation.
–
Connect the appliance mains plug on the connect-
ing cable (see → Electrical connection).
The cooling unit starts to operate after a delay of max.
2 minutes.
After start-up, it may take up to 4 to 4 hours until the
desired temperature is reached.
Note: If the blind closes when the appliance is
switched on, no day signal (see → Night blind/appli-
ance lighting function) is present on the appliance.
