The AquaForce

30XB and 30XBP units are designed to cool

water for the air conditioning of buildings and industrial processes.

Prior to the initial start-up of the 30XB units, the people involved
in the on-site installation, start-up, operation, and maintenance of
this unit should be thoroughly familiar with these instructions and

the specific project data for the installation site.

They are designed for an operating life of 15 years by assuming
a 75% utilisation factor; that is approximately 100,000 operating
hours.

The 30XB liquid chillers are designed to provide a very high level
of safety during installation, start-up, operation and maintenance.
They will provide safe and reliable service when operated within
their application range.

This manual provides the necessary information to familiarize
yourself with the control system before performing start-up
procedures. The procedures in this manual are arranged in the
sequence required for machine installation, start-up, operation
and maintenance.

Always ensure that all required safety measures are followed,
including those in this document, such as, wearing protective
clothing (gloves, ear defenders, safety glasses and shoes), using

appropriate tools, employing qualified and skilled technicians

(electricians, refrigeration engineers) and following local
regulations.

To find out, if these products comply with European directives

(machine safety, low voltage, electromagnetic compatibility,
equipment under pressure etc.) check the declarations of
conformity for these products.

1.1 - Installation safety considerations

Access to the unit must be reserved to authorised personnel,

qualified and trained in monitoring and maintenance. The access

limitation device must be installed by the customer (e.g. cut-off,
enclosure).

After the unit has been received, when it is ready to be installed or
reinstalled, and before it is started up, it must be inspected for
damage. Check that the refrigerant circuit(s) is (are) intact, especially
that no components or pipes have shifted (e.g. following a shock).
If in doubt, carry out a leak tightness check and verify with the
manufacturer that the circuit integrity has not been impaired. If

damage is detected upon receipt, immediately file a claim with the

shipping company.

Carrier strongly recommends employing a specialised

company to unload the machine.
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.
These units are not designed to be lifted from above. Use

slings with the correct capacity, and always follow the lifting

instructions on the certified drawings supplied with 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.

DO NOT COVER ANY PROTECTION DEVICES.

This applies to fuse plugs and relief valves (if used) in the

refrigerant or heat transfer medium circuits. Check if the

original protection plugs are still present at the valve outlets.

These plugs are generally made of plastic and should not be

used. If they are still present, please remove them. Install

devices at the valve outlets or drain piping that prevent the

penetration of foreign bodies (dust, building debris, etc.) and

atmospheric agents (water can form rust or ice). These

devices, as well as the drain piping, must not impair operation

and not lead to a pressure drop that is higher than 10% of the

control pressure.

Classification and control
In accordance with the Pressure Equipment Directive and

national usage monitoring regulations in the European Union

the protection devices for these machines are classified as

follows:

Safety

accessory

(1)

Over pressure protection in

case of an external fire

(2)

Refrigerant Side

High pressure switch

External relief valve

(3)

Rupture disk

Fuse plug

Heat transfer fluid side

External relief valve

(4)

(1) Classified for protection in normal service situations.

(2) Classified for protection in abnormal service situations. These accessories are

sized for fires with a thermal flow of 10kW/m². No combustible matter should be

placed within 6.5m of the unit.

(3) The instantaneous overpressure limitation of 10% of the operating pressure

does not apply to this abnormal service situation.

The control pressure can be higher than the service pressure. In this case, either

the design temperature or the high pressure switch ensures that the service

pressure is not exceeded in normal service situations.

(4) The selection of these relief valves must be made by the personnel responsible

for completing the hydraulic installation.

Do not remove these valves and fuses, even if the fire risk is
under control for a particular installation. There is no
guarantee that the accessories are re-installed if the installation
is changed or for transport with a gas charge.

When the unit is subjected to fire, safety devices prevent rupture

due to over-pressure by releasing the refrigerant. The fluid may

then be decomposed into toxic residues when subjected to the

flame:

Stay away from the unit.

Set up warnings and recommendations for personnel

in charge to stop the fire.

Fire extinguishers appropriate to the system and the

refrigerant type must be easily accessible

All factory-installed relief valves are lead-sealed to prevent any

calibration change. If the relief valves are installed on a

change-over valve, this is equipped with a relief valve on each
