ELECTRICAL SYSTEM
- If the power line connecting the unit to the a.c. supply is incomplete, or if the connection is made with cables of incorrect
cross section and/or with insufficiently rated protective devices, this can result in electric shock, toxicity hazard, damage
to the unit or fire. All work on the electrical system should be carried out referring to the wiring diagram and to the
directions given in this manual, and the system itself must be dedicated.
- Failure to secure the cover enclosing electrical components can lead to the infiltration of dust and water, ultimately
causing electric shocks, damage to the unit, or fire. Always fasten the cover securely to the unit.
- If live metal parts of the unit are not connected properly to the earth system, they can cause electric shock or even
death by electrocution. Make absolutely certain that the connection to the earth system is made in accordance with
correct practice.
- Contact with live parts rendered accessible internally of the unit when the guards are removed can result in electric
shock, burns or death by electrocution. Before exposing these parts, make certain the isolating switch on the power line
to the unit is set to the OFF position and padlocked, and post a warning sign.
- Contact with parts that could become live when the unit is started up can result in electric shock, burns or death by
electrocution. When there is no need for circuits to be powered up, set the isolating switch on the power line to the OFF
position, padlock it and post a warning sign.
MOVING PARTS
- Contact with the fan rotors can cause injury. Before removing the protective grilles or the fans themselves, make certain
the isolating switch on the power line to the unit is set to the OFF position and padlocked, and post a warning sign.
- Contact with the fan rotors can cause injury. Before removing the protective grilles or the fans themselves, make certain
the isolating switch on the power line to the unit is set to the OFF position and padlocked, and post a warning sign.
REFRIGERANTS
- In the event of safety valves coming into operation and releasing refrigerant gas, persons in the vicinity can be injured
or suffer toxic effects. Always wear suitable clothing and protective goggles when working in potential hazard areas. In
the event of refrigerant gas escaping, refer to the “Safety datasheet” for the particular refrigerant.
After any maintenance operation, they must be resealed in an open position; the non-observance of these instructions
could bring the risk of an explosion of the cooling circuit with possible injury to things and people.
- If an open flame or heat source is brought into contact with the refrigerant, or the pressurized gas circuit should
overheat (e.g. during welding operations), this can cause explosion or fire. Do not position any heat source within the
hazard area. Maintenance or repair operations involving welding must be carried out with the system emptied of
refrigerant.
WATER SYSTEM
- Defects affecting pipelines, connections or valves and other control componentry can result in water being leaked or
sprayed from the system, occasioning damage to property or causing short circuits in the unit. Make certain all hydraulic
connections are securely made, following the directions given in the present manual
