Prior to the initial start-up of the 30RB units, the people
involved should be thoroughly familiar with these
instructions.
The 30RB liquid chillers are designed to provide a very
high level of safety and reliability making installation,
start-up, operation and maintenance easier and more
secure. They will provide safe and reliable service when
operated within their application range.
The procedures in this manual are arranged in the sequence
required for machine installation, start-up, operation and
maintenance.
Be sure you understand and follow the procedures and
safety precautions contained in the instructions supplied
with the machine, as well as those listed in this guide, such
as: protective clothing such as gloves, safety glasses, safety
shoes and appropriate tools, and suitable qualifications
(electrical, air conditioning, local legislation).
To find out, if these products comply with European direc-
tives (machine safety, low voltage, electromagnetic compati-
bility, equipment under pressure etc.) check the declarations
of conformity for these products.
• Confirm that the unit received is the one ordered.
Compare the name plate data with the order. The name-
plate is attached to the control box door on the inside.
• The unit name plate must include the following
information:
- Model number - size
- CE marking
- Serial number
- Year of manufacture and pressure and leak
tightness test date
- Refrigerant used
- Refrigerant charge per circuit
- PS: Min./max. allowable pressure (high and low
pressure side)
- TS: Min./max. allowable temperature (high and
low pressure side)
- Globe valve cut-out pressure
- Pressure switch cut-out pressure
- Unit leak test pressure
- Voltage, frequency, number of phases
- Maximum current drawn
- Maximum power input
- Unit net weight
• Confirm that all accessories ordered for on-site
installation have been delivered, and are complete
and undamaged.
The unit must be checked periodically, if necessary
removing the insulation (thermal, acoustic), during its
whole operating life to ensure that no shocks (handling
accessories, tools etc.) have damaged it. If necessary, the
damaged parts must be repaired or replaced. See also
chapter “Maintenance”.
After the unit has been received, and before it is started up,
it must be inspected for damage. Check that the refrigerant
circuits are intact, especially that no components or pipes
have shifted or been damaged (e.g. following a shock). If in
doubt, carry out a leak tightness check. If damage is detected
upon receipt, immediately file a claim with the shipping
company.
Do not remove the skid or the packaging until the unit is
in its final position. These units can be moved with a fork
lift truck, as long as the forks are positioned in the right
place and direction on the unit.
The units can also be lifted with slings, using only the
designated lifting points marked on the unit (labels on
the chassis and a label with all unit handling instructions
are attached to the unit).
Use slings with the correct capacity, and always follow
the lifting instructions on the certified drawings supplied
for the unit.
Safety is only guaranteed, if these instructions are
carefully followed. If this is not the case, there is a risk of
material deterioration and injuries to personnel.
Never cover any safety devices.
This applies to the globe valve in the water circuit and
the globe valve(s) in the cooling circuit(s).
Ensure that the valves are correctly installed, before
operating the unit.
The globe stops are designed and installed to ensure
protection against fire risk. Removing the globe stops is
only permitted if the fire risk is fully controlled and the
responsibility of the user.
All factory-installed globe valves are lead-sealed to
prevent any calibration change.
The safety valves must be connected to discharge pipes for
units installed in confined spaces. These pipes must be
installed in a way that ensures that people and property
are not exposed to refrigerant leaks. These fluids may be
diffused in the air, but far away from any building air
intake, or they must be discharged in a quantity that is
appropriate for a suitably absorbing environment.
Globe valves must be checked periodically. See paragraph
“Repair safety considerations”.
Provide a drain in the discharge circuit, close to each
globe valve, to avoid an accumulation of condensate or
rain water.
All precautions concerning handling of refrigerant must
be observed in accordance with local regulations.
