Preliminary Checks; Check Equipment Received; Moving And Siting The Unit - Carrier AquaForce 30XAV 500 Installation, Operation And Maintenance Instructions

ATTENTION: No part of the unit must be used as a walk-
way, rack or support. Periodically check and repair or if
necessary replace any component or piping that shows signs
of damage.
The refrigerant 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.
Use mechanical lifting equipment (crane, hoist, winch, etc.)
to lift or move heavy components. For lighter components,
use lifting equipment when there is a risk of slipping or losing
your balance.
Use only original replacement parts for any repair or
component replacement. Consult the list of replacement
parts that corresponds to the specification of the original
equipment.
Do not drain water circuits containing industrial brines,
without informing the technical service department at the
installation site or a competent body first.
Close the entering and leaving water shutoff valves and drain the
unit water circuit, before working on the components installed on
the circuit (screen filter, pump, water flow switch, etc.).
Do not loosen the water box bolts until the water boxes have
been completely drained.
Periodically inspect all valves, fittings and pipes of the
refrigerant and hydronic circuits to ensure that they do not
show any corrosion or any signs of leaks.
It is recommended to wear ear defenders, when working near
the unit and the unit is in operation.

2 - PRELIMINARY CHECKS

2.1 - Check equipment received

• Check that the unit has not been damaged during
transport and that no parts are missing. If the unit has
been damaged or the shipment is incomplete, send a
claim to the shipping company.
• Compare the name plate data with the order. The name
plate is attached in two places to the unit:
- On one of the unit sides on the outside
- On the control box door on the inside.
• 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)
- Pressure switch cut-out pressure
- Unit leak test pressure
8
- 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 during its whole
operating life to ensure that no shocks (handling accessories,
tools etc.) have damaged it. If necessary, damaged parts must
be repaired or replaced. See also chapter 8 - "Standard
maintenance".

2.2 - Moving and siting the unit

2.2.1 - Moving
See chapter 1.1 "Installation safety considerations".
2.2.2 - Placing the unit
The machine must be installed in a place that is not accessible
to the public or protected against access by non-authorised
persons.
In case of extra-high units the machine environment must
permit easy access for maintenance operations.
Always refer to the chapter 3 "Dimensions, clearances" to
confirm that there is adequate space for all connections and
service operations. For the centre of gravity coordinates, the
position of the unit mounting holes, and the weight
distribution points, refer to the certified dimensional drawing
supplied with the unit.
The support points under the chassis must have at least the
size of the chassis opening at the lifting point (minimum 220
x 180 mm) in order to prevent a deformation of the chassis.
Typical applications of these units are in refrigeration
systems, and they do not require earthquake resistance.
Earthquake resistance has not been verified.
CAUTION: Only use slings at the designated lifting points
which are marked on the unit.
Before siting the unit check that:
• The permitted loading at the site is adequate or that
appropriate strenghtening measures have been taken.
• The unit is installed level on an even surface (maximum
tolerance is 5 mm in both axes).
• There is adequate space above the unit for air flow and
to ensure access to the components.
• If the support structure is sensitive to vibration and/or
noise transmission, it is advisable to insert anti-vibration
mounts (elastomeric mounts or springs) between the
unit and the structure. Selection of these devices is based
on the system characteristics and the comfort level
required and should be made by technical specialists.
• The number of support points is adequate and that they
are in the right places.
• The location is not subject to flooding.
• For outdoor installations, where heavy snowfall is likely
and long periods of sub-zero temperatures are normal,
provision has to be made to prevent snow accumulating
by raising the unit above the height of drifts normally
