19XR (PIC II) Hermetic Centrifugal Liquid Chillers 50 Hz - Carrier

3 - INSTALLATION
3.1 - Introduction
The 19XR machine is factory assembled, wired, leak tested
and electrically tested. Installation (not by Carrier) consists
primarily of establishing water and electrical services to the
machine. The rigging, installation, field wiring, field piping,
and insulation of waterbox covers are the responsibilty of the
contractor and/or customer. Carrier has no installation
responsibilities for the equipment.
3.2 - Receiving the machine
3.2.1 - Inspect shipment
CAUTION: Do not open any valves or loosen any connections.
The standard 19XR machine is shipped with a full refrigerant
charge. Some machines may be shipped with a nitrogen holding
charge as an option.
Inspect for shipping damage while machine is still on
shipping conveyance. If machine appears to be damaged or has
been torn loose from its anchorage, have it examined by
transportation inspectors before removal. Forward claim
papers directly to transportation company. Manufacturer is
not responsible for any damage incurred in transit.
Confirm that the unit received is the one ordered. Compare
the name plate data with the order.
The unit name plate must include the following
information:
- Version number
- Model number
- CE marking
- Serial number
- Year of manufacture and test date
- Refrigerant used and refrigerant class
- Refrigerant charge per circuit
- Containment fluid to be used
- 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

Check all items against shipping list. Immediately notify the
nearest Carrier representative if any item is missing.
To prevent loss or damage (standard EN 378-2 11.22 k, annex
A and B), leave all parts in original packages until beginning
installation. All openings are closed with covers or plugs to
prevent dirt and debris from entering machine components
during shipping. A full operating oil charge is placed in the
oil sump before shipment.
3.2.2 - Provide machine protection
Protect machine and starter from construction dirt and moisture.
Keep protective shipping covers in place until machine is ready
for installation.
Do not keep the 19XR units outside where they are exposed to
the weather, as the sensitive control mechanism and the
electronic modules may be damaged.
The unit must be checked periodically 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”.
If machine is exposed to freezing temperatures after water
circuits have been installed, open waterbox drains and remove
all water from cooler and condenser. Leave drains open until
system is filled.
3.3 - Rigging the Machine
The 19XR machine can be rigged as an entire assembly. It also
has flanged connections that allow the compressor, cooler, and
condenser sections to be separated and rigged individually.
3.3.1 - Rigging the complete machine
See rigging instructions on label attached to machine. Also refer
to physical data and Tables 1-7 (chapter 3.3.3). Lift machine
only from the points indicated in the instructions supplied and
in the machine rigging drawings. Each lifting cable or chain
must be capable of supporting the entire weight of the machine.
WARNING: Lifting machine from points other than those
specified may result in serious damage to the unit and personal
injury. Rigging equipment and procedures must be adequate
for machine weight. See Tables 1-7 (chapter 3.3.3) for
machine weights.
NOTE: These weights are broken down into component
sections for use when installing the unit in sections. For the
complete machine weight, add all component sections and
refrigerant charge together. See Tables 1-7 (chapter 3.3.3) for
machine component weights.
IMPORTANT: Make sure that rigging cable is over the rigging
bar before lifting.
