A person authorised by the owner to carry out all the operations of regulation and control on the Trane unit which are
specifically 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 replacement 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 fins, without security
gratings (optional) or closing panelling, the following precautions must be taken
•
mark the areas with contact risks.
•
apply warning signs.
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 flow of 3 metres.
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.
General safety precautions
The operator must only intervene on the unit controls; 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 machine; he or she must not open any
machine 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 flame (welding) or compressed air.
•
If the unit is located in a closed environment, wear hearing protection.
•
before disconnecting, removing tubes, filters, 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.
