Installation and maintenance instructions 0020285063_05
1.3.4 Risk of death due to lack of safety
devices
The basic diagrams included in this docu-
ment do not show all safety devices required
for correct installation.
▶
Install the necessary safety devices in the
installation.
▶
Observe the applicable national and inter-
national laws, standards and directives.
1.3.5 Risk of death due to explosive and
flammable materials
▶
Do not use the product in storage rooms
that contain explosive or flammable sub-
stances (such as petrol, paper or paint).
1.3.6 Risk of death caused by fire or
explosion if there is a leak in the
refrigerant circuit
The product contains the combustible refri-
gerant R290. In the event of a leak, escaping
refrigerant may mix with air to form a flam-
mable atmosphere. There is a risk of fire and
explosion.
A protective zone is defined for the area
close around the product. See section
"Protective zone".
▶
If you are working on the product when it
is open, before starting work, use a gas
sniffer to ensure that there is no leak.
▶
The gas sniffer itself must not be an igni-
tion source. The gas sniffer must be calib-
rated to R290 refrigerant and set to
≤
25%
of the lower explosive limit.
▶
Keep all ignition sources away from the
protective zone. In particular, open flames,
hot surfaces with temperatures above
370 °C, electrical devices or tools that are
not free from electrical sources, static dis-
charges.
1.3.7 Risk of death caused by fire
or explosion when removing the
refrigerant
The product contains the combustible refri-
gerant R290. The refrigerant may mix with air
to form a flammable atmosphere. There is a
risk of fire and explosion.
▶
Only carry out the work if you are compet-
ent at handling R290 refrigerant.
▶
Wear suitable personal protective equip-
ment and bring a fire extinguisher with you.
▶
Only use tools and units that are permit-
ted for R290 refrigerant and are in proper
working condition.
▶
Ensure that no air gets into the refrigerant
circuit, into refrigerant-carrying tools or
units, or into the refrigerant cylinder.
▶
Note that the refrigerant R290 must never
be introduced into the sewage system.
1.3.8 Risk of burns, scalds and frostbite
due to hot and cold components
There is a risk of burns and frostbite from
some components, particularly uninsulated
pipelines.
▶
Only carry out work on the components
once these have reached environmental
temperature.
1.3.9 Material damage due to unsuitable
installation surface
The installation surface must be even and
have sufficient load-bearing capacity to sup-
port the operating weight of the product. An
uneven installation surface may cause leaks
in the product.
If the installation surface does not have suffi-
cient load-bearing capacity, the product may
topple.
There is a risk of death if the connections are
subject to leaks.
▶
Make sure that the product is positioned
flush against the installation surface.
▶
Ensure that the installation surface has
sufficient load-bearing capacity to bear the
operating weight of the product.
1.3.10 Risk of injury due to the heavy weight
of the product
The product weighs over 50 kg.
▶
Make sure that the product is carried by at
least two people.
▶
Use suitable transport and lifting equip-
ment, in accordance with your job safety
analysis.
▶
Use suitable personal protective equip-
ment: Gloves, safety footwear, protective
goggles, protective helmet.
