Belts and fans :
This refrigeration unit is equipped with Auto--start/stop, it may start at any time
and without warning.
When the unit is running beware of belts and fans that are moving.
Before servicing refrigeration unit, make sure the main power switch is on the
OFF position. Ensure the unit will not restart. Lock--out / Tag--out can be
performed as described above.
When there is protective structure (fan grid or guard for example) make sure
they are in place. Never removed them when the refrigeration unit is running.
Always keep your hands, body
parts, clothes, hairs and
tools far
from moving
parts.
Electricity :
When this refrigeration unit is running in electrical operation, some devices are
powere
d
up especiall
y
in the
electri
cal control box.
Before servicing refrigeration unit, make sure the main power switch is on the
OFF position. Ensure this refrigeration unit is disconnected from the local
electrical network.Lock--out / Tag--out can be performed as described above.
Before working in the electrical control box, it is required to control the lack of
tension.
WHEN IT IS NECESSARY TO WORK IN THE ELECTRICAL CONTROL BOX
UNDER TENSION, PEOPLE MUST BE QUALIFIED FOR WORKS UNDER
LOW OR HIGH VOLTAGE.
Always use adequate tools and Personal Protective Equipme
nt when
workin
g
on electrical devices : safety gloves and safety glasses.
Engine coolant :
This refrigeration unit is equipped with a pressurised cooling system. Under
normal operating conditions, the coolant in the engine and radiator is under high
pressure and very hot.
Coolant is very slippery. It can be harmful in case of ingestion.
Never remove the cap from a hot radiator when this refrigeration unit is running
or immediately after.
If the cap must be removed, wait at least 10 minutes and then do so very slowly
in order to release the pressure without spray.
In case of leakage, immediatly clean the floor to prevent slipping.
Avoid contac
t
with the
skin and eyes.
Always use Personal Protective
Equipment when handling engine coolant : safety clothes, safety gloves and
safety glasses.
Refrigerant :
The refrigerant contained in this refrigeration unit can cause frosbite, severe
burns or blindness in case of projection and direct contact with the skin or eyes.
In contact with flame or heat refrigerant generate toxic gas.
Refrigerant handling must be done by qualified people.
Keep any flame, any lighted object or any source of sparks away from the refri-
gerant unit.
Always use Personal Protective Equipm
ent when handling refrigeran
t
:
safety

When this refrigeration unit is running or even after, different components can
be very cold or hot (exhaust pipe, tubes, coils, receiver, accumulator or engine
for example)
Beware when operating closed from cold or hot components.
Always use adequate safety gloves when doing any
mainte
nance on this
refrigeration unit.
Cutti
ngs
:
Beware when handling or operating closed from parts that could be sharp (coils,
evaporators, clamps for example).
Always
use
adequ

glove
s
when
doing
any

charging the battery normally vents small amounts of flammable and explosive
hydrogen gas.
Projections of acids on the skin or eyes can cause severe burns.
Keep any flame, any lighted object or any source of sparks away from the battery
elements.
Always use Personal Protective Equipm
