Behavior rules for VENTO GREEN devices (> 150g refrigerant R-290)
with a critical alarm
of priority 1+
(red warning light illuminated, indication of leaks in the refrigerant circuit):
The automatic system control initiates important measures immediately.
Nevertheless, the
following
behavioral rules
must be observed within a distance of 0.5 m to the refrigerator
boundary edges until the volatilization of the exiting refrigerant has been detected (reliable gas
concentration measurement):
►
Disconnect the device immediately (see
→
Chapter 9.2).
►
Secure the device against restarting.
►
Lock the passage in front of the defective device.
►
Keep away from ignition sources (heat, sparks, open flames, hot surfaces).
►
Do not bring any hot surfaces (above 370°C/698°F) into proximity.
►
Do not operate any devices, electrical switches or bells that are not explosion-proof.
►
Ensure good ventilation.
►
Contact the maintenance service (see
→
Chapter 10.4).
•
Dispose of devices with flammable refrigerant and devices with insulating foam (thermal insulation
polyurethane foam with pentane) appropriately. Inquire with the responsible authorities about the safety
and statutory disposal regulations applicable to you.
The product was designed to take into account the environmental and disposal friendliness of AHT devices.
The refrigerant R-290 and the propellant pentane (for the insulating foam) do not have any ozone depletion
potential and do not contribute directly to the greenhouse effect.

-tilt device.
► The device must only be installed and dismantled with an anti
-tilt device.
►
Anti-tip mounting service (see
→
Fig. 7.1) must only be removed again when the danger of tilting
is no longer present. Fuse protection, e.g. by wall or opposite device for island installation.
(Anti-tilt mounting service is supplied as an accessory by the AHT installation service.)
►
Additional device-specific anti-tilt device (see
→
