Safety regulations

2.10 Safety regulations
Preamble
All Trane units are designed, built and inspected in
compliance with the European Community Directives n°
98/37/CE (three phase power supply), EN 60335 Part 1
and 2, low voltage directive 73/23CEE, electromagnetic
compatibility directive EMC 89/336CEE, Pressure
Equipment Directive 97/23/CEE. Before using the unit
read carefully the recommendations reported in the
following manual.
Defi nition
Owner: The legal representative of the company, body
or natural person who owns the plant in which the Trane
unit is installed: he or she is responsible for the control
and respect of all the safety regulations indicated in this
manual as well as the national ones in force.
Installer: The legal representative of the company
appointed by the owner to position and hydraulically,
electrically etc. connect the Trane unit to the plant:
he or she is responsible for handling and the correct
installation of the unit in accordance with the indications
in this manual and with the national regulations in force.
Operator: A person authorised by the owner to carry out
all the operations of regulation and control on the Trane
unit which are specifi cally mentioned in this manual. He
or she should keep to actions described in the manual
and limit his or her action to what is explicitly allowed.
Technician: A person who is directly authorised by Trane
or, secondarily, for all EU countries except for Italy, by
the distributor of the Trane product, under their own
responsibility, to carry out all ordinary or extraordinary
maintenance operations, as well as regulations, controls,
repairs and parts repositioning which may be necessary
during the lifetime of the unit.
Access to dangerous areas
The access to the unit dangerous areas is usually
obstructed through protection panels, which are
removable, by using a tool. Axial fans are protected
with accident prevention grilles. Centrifugal fans are not
protected on the discharge, as they have to be connected
to ducts. In case they have to run without ducts, it is the
installer duty to provide protection grilles.
Finned coil, for units not equipped with coil protection
grilles, is completely accessible with danger for cuts and
abrasions. In these cases technicians and operators must
be aware about this risk.
For all the units which allow access to the cooling piping
or to the packaged condensing coils with fi ns, without
security gratings (optional) or closing panelling, the
following precautions must be taken:
-mark the areas with contact risks.
-apply WARNING! signs.
14
The danger zone must be of a suitable size to avoid
any contact, even accidental contact. In the presence
of safety valves without relevant remote controls, the
operating area must be of a size which considers a
range of action of the discharge fl ow of 3 meters. Trane
declines any responsibility for damage to things and
unauthorised personnel in case of absence of clear
and static limiting systems of the risk areas and of the
relevant WARNING! and danger signs.
2.11

General precautions

The operator must only intervene on the unit commands;
he or she must not open any panels except for the one
which gives access to the command module.
The installer must only intervene on the connections
between the plant and the unit; he or she must not open
any unit panels nor carry out any commands.
The following precautions should be made when
approaching or working on the unit:
• Do not wear jewellery, baggy clothes or any other
accessory which can get caught up.
• Use appropriate protection (gloves, glasses
etc.) when using an open fl ame (welding) or
compressed air.
• If the unit is located in a closed environment, wear
hearing protection.
• Before disconnecting, rehandling tubes, fi lters,
joints or other line parts intercept the connection
tubes, empty them until the pressure reaches that
of the atmosphere.
• Do not use your hands to check for possible
pressure losses.
• Always use tools which are in good condition;
make sure the instructions have been fully
understood before using them.
• Make sure that any tools, electrical cables or other
loose objects have been removed before closing
the unit and starting it up again.
