Final Recommendations - Carrier AQUASNAP 30RB series Installation, Operation And Maintenance Instructions

30RB/30RQ - 30RBY/30RQY
Maintenance
Servicing recommendations
- Maintenance of the unit must be carried out by skilled personnel only.
Nevertheless, the easiest operations, such as cleaning of the battery
and the unit external parts can be carried out by non-skilled
personnel.
- No part of the unit must be used as a walkway, rack or support.
Periodically check and repair or if necessary replace any component
or piping that shows signs of damage. Do not step on refrigerant lines.
The lines can break under the weight and release refrigerant, causing
personal injury. Do not climb on a machine. Use a platform, or staging
to work at higher levels.
- For any operation on the unit follow thoroughly the instructions shown
in the manual and on the unit labels as well as the Safety Standards.
During any handling, maintenance and service operations the
engineers working on the unit must be equipped with safety gloves,
glasses, shoes and protective clothing. Pay attention to burns when
brazing.
- Use only Carrier Original Spare Parts when repair is required. Always
make sure the spare parts are installed correctly. Always install the
spare parts in the original position.
- The products that may be added for thermal insulation of the
containers during the water piping connection procedure must be
chemically neutral in relation to the materials and coatings to which
they are applied. This is also the case for the products originally
supplied by Carrier SCS.
- Before replacing any of the elements in the cooling circuit, ensure that
the entire refrigerant charge is removed from both the high and low
pressure sides of the unit.
- The control elements of the cooling system are highly sensitive.
If they need to be replaced, care should be taken not to overheat them
with blowlamps whilst soldering.
A damp cloth should be wrapped around the component to be
soldered, and the flame directed away from the component body.
- Silver alloy soldering rods should always be used.
- If the total unit gas charge has to be replaced, the quantity should be
as given on the nameplate and the unit should be properly evacuated
beforehand.
- During unit operation all panels should be in place, including the
electrical box access panel.
- If it is necessary to cut the lines of the refrigerant circuit, tube cutters
should always be used and never tools which produce burrs. All
refrigerant circuit tubing should be of copper, specially made for
refrigeration purposes.

Final recommendations

The unit you have purchased has undergone strict quality control
procedures before leaving the factory.
All components, including the control systems and electrical equipment,
etc., are certified by our Quality Control Department, and tested
under the harshest possible operating conditions in our laboratories.
However, after leaving the factory, it is possible that one or more of
these elements may be damaged due to causes beyond our control.
In such an event, the user should not work on any of the internal
components, or subject the unit to operating conditions which are
not specified in this manual, since serious damage may result and the
guarantee would be invalidated. Repair and maintenance work should
always be left to the installer.
We recommend to apply the EN 378-4.
All recommendations concerning unit installation are intended as a
guideline. The installer should carry out the installation according to the
design conditions and should comply with all applicable regulations for
air conditioning and refrigeration installations.
NOTE: The manufacturer does not accept responsibility for any
malfunctions resulting from misuse of the equipment.
GB - 22
Fire and explosion
When this machine is subjected to the heat of a fire, a device prevents
explosion releasing the refrigerant (by a fusible plug). This fluid can be
decomposed into toxic waste when subjected to flame:
- Stay away from this machine,
- Set up the warning and recommendation for personnel responsible for
stopping fire,
- Appropriate fire extinguishers for the system and the refrigerant types
used must be within easy reach.
