to persons, things or the unit itself. Periodically check that all of
the panels are correctly closed and fixed. If there is a fire the
temperature of the refrigerant could reach values that increase
the pressure to beyond the safety valve with the consequent
possible projection of the refrigerant itself or explosion of the
circuit parts that remain isolated by the closure of the tap. Do
not remain in the proximity of the safety valve .
and never leave the refrigerating system taps closed.
Electric parts
An incomplete attachment line to the electric network or with
incorrectly sized cables and/or unsuitable protective devices can
cause electric shocks, intoxication, damage to the unit or fires.
Carry out all of the work on the electric system referring to the
electric layout and the present manual ensuring the use of a
system thereto dedicated. An incorrect fixing of the electric
components cover may favour the entry of dust, water etc inside
and may consequently can electric shocks, damage to the unit or
fires.
Always fix the unit cover properly. When the metallic mass of the
unit is under voltage and is not correctly connected to the
earthing system it may be as source of electric shock and
electrocution.
Always pay particular attention to the implementation of the
earthing system connections. Contact with parts under voltage
accessible inside the unit after the removal of the guards can
cause electric shocks, burns and electrocution.
Open and padlock the general isolator prior to removing the
guards and signal work in progress with the appropriate shield.
Contact with parts that could be under voltage due to the start
up of the unit may cause electric shocks, burns and
electrocution.
When voltage is necessary for the circuit open the isolator on
the attachment line of the unit itself, padlock it and display the
appropriate warning shield.
Moving parts
Contact with the transmissions or with the fan aspiration can
cause injuries. Prior to entering the inside of the unit open the
isolater situated on the connection line of the unit itself, padlock
and display the suitable sign.
Contact with the fans can cause injuries.
to removing the protective grill or the fans, open the isolator on
the attachment line of the unit itself, padlock it and display the
appropriate warning sign.
Refrigerant
The intervention of the safety valve and the consequent expulsion
of the gas refrigerant may cause injuries and intoxication. Always
wear suitable clothing including protective gloves and eyeglasses
for operations inside the danger zone.
Should the gas refrigerant leak please refer to the refrigerant
"Safety sheet".
Contact between open flames or heat sources with the refrigerant
or the heating of the gas circuit under pressure (e.g. during
welding operations) may cause explosions or fires.
Do not place any heat source inside the danger zone.
The maintenance or repair interventions which include welding
must be carried out with the system off.
