2 | Safety
Flammable refrigerants
WARNING
The refrigerant is highly flammable. If
leaks occur, refrigerant can escape and
cause an explosive gas/air mixture.
This can result in fire and explosion with a
subsequent fire risk.
▪ Refrigerant R-290 (propane) is classified in
safety group A3 according to EN 378-1.
The refrigerant used and the filling quantity
can be seen on the rating plate (see
→Rating plate and serial number).
▪ Keep ignition sources away (heat, sparks,
open flames, hot surfaces).
▪ Use a damp cloth or sponge to remove
condensation water and for cleaning. Do
not use dry cloths or sponges to dry the
appliance. (Risk of electrostatic charge
and sparking)
▪ 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.
▪ Do not obstruct the ventilation openings in
the appliance housing. Use only original
accessory parts.
▪ Do not use any mechanical devices or
other means (e.g. ice scrapers) to acceler-
ate the defrosting process.
▪ Do not operate any electrical devices (e.g.
wet vacuum cleaners) inside the cooling
compartment that do not correspond to the
design recommended by the manufacturer.
Appliances with explosion protection mark-
ings (see → Explanation of symbols) are
permitted.
▪ Do not use steam or high-pressure clean-
ers for basic cleaning.
▪ Only install the appliance in well-ventilated
rooms.
▪ Do not install the appliance in cellars or
lowered rooms.
▪ Ducts and wall bushings must be sealed un-
der and behind the unit to protect against fire.
▪ Do not damage the refrigerant circuit.
▪ Do not expose the appliance to tempera-
tures higher than 70°C (158°F) during
transport and storage.
▪ Avoid transmitting pulsations and vibra-
tions to the appliance.
▪ Do not allow external forces to act on the
appliance, e.g. careless handling with a lift
truck or floor cleaning machine.
▪ The operator must not drill into the appli-
ance or carry out any other work on it.
▪ Do not crush or bend pipes.
▪ Only qualified staff may carry out work on
the refrigerant circuit.
▪ Only open the refrigerant circuit and suck
off the refrigerant in well-ventilated rooms
outside store business hours (when cus-
tomers are not present) or outdoors.
▪ Disconnect the appliance prior to all
maintenance, service, or repair work (see
34 / 671
→Shutdown). Secure the appliance
against reconnection.
▪ During the repair a competent person with
knowledge of local conditions must be
available as contact for the qualified staff.
CAUTION
Liquid refrigerant.
Frostbite to skin.
▪ Wear safety goggles and safety gloves.
▪ Protect hands and face from contact with
liquid/leaking refrigerant.
Dispose of devices with flammable refrigerant and in-
sulating foam (thermal insulation polyurethane foam
with pentane) appropriately. Inquire with the responsi-
ble authorities about the safety and statutory disposal
regulations applicable to you.

2.5.3 Mechanical hazards

WARNING
Transport of the appliances with indus-
trial trucks.
Risk of injury to persons in the event of a collision.
▪ Observe transport routes for industrial
trucks.
▪ Secure transported goods.
▪ Only trained personnel may operate indus-
trial trucks.
▪ Note the centre of gravity of the device for
safe lifting of the load with the forklift. Infor-
mation is provided on the front and back of
the device packaging.
Appliance tipping hazard.
Persons may become trapped.
▪ Remove the transport frames only when in
the stable and final installation position.
Use an anti-tilt device.
▪ The device may only be installed and dis-
mantled with an anti-tilt device.
▪ Do not remove the anti-tilt device until there
is no more risk of tilting. Fuse protection is
provided, for example, by a wall or opposite
device for island installation. Anti-tilt device
is supplied as an accessory by the AHT in-
stallation service.
▪ Do not remove the additional device-spe-
cific anti-tilt device after installation (see →
Setup and installation). Observe the sepa-
rate assembly instructions.
▪ If you have any questions, contact the
maintenance service (see →Maintenance
services).
Dispose of packaging material and film.
Suffocation hazard.
▪ Keep packaging material and film away
from children.
▪ Do not allow children to play with packaging
material or film.
