1. Safety & Handling (cont.)
Reminders:
1. Keep a suitable fi re extinguisher near the work site. Check
the fi re extinguisher regularly to make sure it is fully
charged and working perfectly.
2. Use dry nitrogen to pressurize and check the system
for leaks. Always use a good regulator. Be careful not to
exceed 3790 kPa (550 psig) of test pressure on airtight
compressors.
3.
Use appropriate Personal Protective Equipment (PPE)
when you need to remove the system refrigerant.
Installation safety considerations
After receiving it, when the unit is ready to be installed or
reinstalled, and before its start-up, check for damages. Make
sure the refrigerant circuit(s) is (are) intact. Mainly, ensure
that components or pipes have not changed position (e.g.
after a crash). If in doubt, test for leaks and check with the
manufacturer that the circuit has not been damaged. If
damage is detected upon receipt, complain to the company
that sent the unit.
Do not remove the frame or the packaging until the unit is
in its final position. These units can be moved with a “fork”
type car, as long as the booms (forks) are positioned in the
correct location and direction on the unit.
The units can also be lifted with hooks, using only the lifting
points marked at the four corners of the unit base.
These units are not designed to be lifted from above. Use the
hooks with the correct capacity, and always follow the lifting
instructions specifi ed in the certifi ed drawings supplied with
the unit.
Safety will only be guaranteed if these instructions are
carefully observed. If they are not, there are risks of material
damage or personal injury.
Never cover any safety devices.
Make sure the valve(s) if used (s) in the cooling circuit is
installed correctly before operating the unit (the valves are
not systematically installed in the units, but this may be
required by certain national safety codes, depending on the
destination country).
Make sure that no refrigerant leaks from the safety valves into
the building. Relief valve outlets should be directed to the
outside. Refrigerant accumulation in an enclosed space can
displace oxygen and cause asphyxiation or explosions. The
safety valve has a threaded connection 7/8 “UNF (see FIG. 1).
This equipment generates, uses and can radiate radio
frequency and, if not installed and used in accordance
with these instructions, this equipment can cause radio
interference.
Refer to the applicable Codes and / or Standards for on-site
installation to ensure that the electrical wiring complies
with the standards and requirements specifi ed.
IMPORTANT
Electrical shock can cause injury or death. Turn
off the power of this equipment during the installation.
There may be more than one disconnect switch. Put
signs on all disconnection spots to warn others not to
restore energy until the job is completed.
WARNING
DANGER
NEVER use open fl ame to detect leaks in the plant or in the
units. Use the recommended equipment and procedures
to test for leaks.
NEVER compress air using the unit compressor.
Failure to follow these instructions can cause potential
damage to the product, the installation and the
physical integrity of persons who are nearby during the
procedure(s).
- Observe all safety codes.
- Use Personal Protective Equipment (PPE) suitable for
the work to be done. (E.g.: Wear safety goggles and
gloves)
- Never put your hand inside the unit while the fan is
running.
- Protect unit axial fan discharge if unauthorized persons
have easy access to it.
- Disconnect the power supply before working on the
unit to prevent accidents. Leave a warning that the unit
is in service.
ATTENTION
THINK SAFE!
