Safety and hazard precautions
WARNING
Electrical hazard
Work on the trailer refrigeration unit only when the main plug
is disconnected.
Make sure the trailer refrigeration unit is not restarted while working
on it by following suitable measures.
Never attempt to plug in or unplug the trailer refrigeration unit from
the power supply when your hands are wet.
WARNING
Electrical hazard
Strictly observe the following safety rules when working on the
trailer refrigeration unit’s electrical system:
• Switch OFF.
• Block the switch to prevent accidental reactivation.
• Disconnect the power supply.
• Connect to earth (ground) and short-circuit.
• Cover or isolate all nearby live components.
Electrical connection of the trailer refrigeration unit must be
carried out by a qualified electrician.
WARNING
Toxic gas hazard
The fluorocarbon refrigerants contained in the refrigeration unit may
produce toxic fumes if exposed to a naked flame or an electrical spark.
These fumes are severe respiratory irritants, potentially capable of
causing death.
The refrigerant tends to displace air and can cause oxygen depletion,
which may result in death by suffocation.
Take special care when working on the trailer refrigeration
unit, particularly in an enclosed or confined space with a
limited supply of fresh air.
WARNING
Fire and explosion hazard from flammable materials.
DO NOT expose to naked flames, electrical sparks or other sources
of ignition. Do not smoke.
Observe fire/explosion-prevention measures.

WARNING
Danger arising from unauthorised modification.
DO NOT drill any extra holes into the trailer refrigeration unit, as this
may damage important components.
Accide ntal drilling to electrical wiring or refrigerant
conduits may cause a fire.
WARNING
Risk of damage to health from leaking refrigerant.
During maintenance or repair work on the refrigerant circuit,
refrigerant emissions may occur. These emissions can be liquid or
gaseous and pose a threat to humans and the environment.
Al way s use suitable personal protective equipment
(including goggles, respiratory mask and protective gloves)
if leaking refrigerant is present.
CAUTION
Burn hazard.
Certain parts of the trailer refrigeration unit (e.g. the condenser,
evaporator and tubes) may still be hot after operation.
Let the components cool off before working on the trailer refrigeration
unit.
CAUTION
Risk of long-term damage to the environment.
The operating materials (refrigerant and refrigerant oil) are NOT
biodegradable. Observe the safety data sheets or operating
instructions supplied with the materials used.
Obs erve the corresponding local environmental
regulations when disposing of items that have been
contaminated with operating materials.
CAUTION
Risk of injury from rotating parts
Keep your distance from rotating fan blades.
Contact with the sharp edges of fan blades can result in injury.

Refrigerant-handling precautions
Although hydrofluorocarbon refrigerants are classed as “safe”, you
should still observe certain precautions during the handling, installation
and maintenance of the trailer refrigeration unit. Liquid
hydrofluorocarbon refrigerants evaporate rapidly when released into
the atmosphere, and quickly ice up everything that they touch. Skin
contact can lead to severe, frostbite-like injury. Hydrofluorocarbon
refrigerants may produce toxic fumes if exposed to a naked flame or
an electrical spark. These fumes are severe respiratory irritants,
potentially capable of causing death.
2.4.1 First aid
In the event of frostbite, protect the affected area from further injuries,
avoiding contact with the refrigerant and additional measures.
Contact of refrigerant or refrigerant oil with the eyes: In case of
contact with the refrigerant or refrigerant oil, immediately flush eyes
with large amounts of water (for at least 15 minutes) and get prompt
medical attention.
Skin frostbite:
•Remove refrigerant-contaminated clothing and footwear.
•Thoroughly rinse off the refrigerant with abundant lukewarm water.
•DO NOT apply heat (e.g. by rubbing or with a hot-water bottle).
•Seek medical attention immediately. While you are waiting for help to
arrive, cover the affected area as loosely as possible with a large sterile
dressing.
Inhalation of refrigerant:
Seek medical attention immediately and bring the injured person into
the fresh air. Administer artificial respiration if required.
2.4.2 Environmental regulations
GOVI trailer refrigeration units are shipped with a suitable charge of
refrigerant R452A.
If you detect any fault in the refrigerant circuit, or signs of leakage
from the trailer refrigeration unit, have the device examined and
repaired by a qualified specialist. DO NOT allow refrigerant to escape
into the open air. Please read the safety instructions and hazard
warnings in section 2.3 Safety and hazard precautions,as well as
the manufacturer’s data sheet for the refrigerant R452A. Dispose of
defective refrigeration units and drained-off refrigerant in accordance
with applicable environmental regulations.

Intended use
This trailer refrigeration unit is designed for use in refrigerated trailers
that are not exposed to any explosion or fire hazard. For that
purpose, the trailer refrigeration unit is mounted stationary at the front
wall of the refrigerated trailer by a mechanical fasting system (not
included).
At outside temperatures between -20 °C and +38 °C the trailer
refrigeration unit enables inside temperatures from -20 °C to 10 °C.
•The trailer refrigeration unit is not designed for operation in locations
classed as AP.PE EEx (explosion hazard).
•The trailer refrigeration unit is not designed for use in places exposed
to fire hazard.
•The trailer refrigeration unit is not equipped with reinforced electrical
or mechanical protective elements to withstand aggressive weather
conditions.
Ensure the trailer refrigeration unit is properly ventilated when placing
the trailer. Ensure adequate air circulation and sufficient space for
proper maintenance access. DO NOT expose the trailer refrigeration
unit to direct sunlight. Ensure proper air circulation when placing items
inside the trailer, and be careful not to block the evaporator. DO NOT
place heat-emitting items in the refrigerated unit.
The trailer refrigeration unit is not intended for any use other than as
described above. All other usage shall be considered improper, and is
either prohibited or requires the approval/permission of the manufacturer.
“Intended use” also includes compliance with specified maintenance and
repair-work requirements. See section 10 Maintenance.
