2 - PRELIMINARY CHECKS

2.1 - 

Check equipment received

 

Inspect the unit for damage or missing parts. If damage is 

detected, or if shipment is incomplete, immediately file a claim 

with the shipping company.

 

■ 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

 - Fluid being transported

 - 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 pressures

 - 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  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 “Standard 

maintenance”.

2.2 - 

Moving and sitting the unit

2.2.1 - 

Moving

See chapter “Installation safety considerations”.

CAUTION: Only use slings at the designated lifting points 

which are marked on the unit. 

2.2.2 - Sitting the unit

Always refer to the chapter “Dimensions and 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.

Typical applications of these units are in refrigeration systems, 

and they do not require earthquake resistance. Earthquake 

resistance has not been verified.

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.

 

the number of support points is adequate and that they are in 

the right places.

 

■ the location is not subject to flooding.

CAUTION: Lift and set down the unit with great care. Tilting 

and jarring can damage the unit and impair unit operation.

2.2.3 - 

Checks before system start-up

Before the start-up of the refrigeration system, the complete 

installation,  including  the  refrigeration  system  must  be  verified 

against the installation drawings, dimensional drawings, system 

piping and instrumentation diagrams and the wiring diagrams.
During the installation test national regulations must be followed. 

If no national regulation exists, standards such EN-378 or ISO-

5149 can be used as a guide.
External visual installation checks:

 

Ensure that the machine is charged with refrigerant. Verify on 

the  unit  nameplate  that  the  ‘fluid  being  transported’  is  not 

nitrogen.

 

Compare the complete installation with the refrigeration system 

and power circuit diagrams.

 

Check that all protection documents and equipment provided 

by the manufacturer (dimensional drawings, P&ID, declarations 

etc.) to comply with the regulations are present.

 

Verify that the environmental safety and protection and devices 

and arrangements provided by the manufacturer to comply with 

the regulations are in place.

 

■ Verify that all document for pressure containers, certificates, 

name plates, files, instruction manuals provided by the 

manufacturer to comply with the regulations are present.

 

Verify the free passage of access and safety routes.

 

Check that ventilation in the plant room is adequate.

 

Check that refrigerant detectors are present.

 

Verify the instructions and directives to prevent the deliberate 

removal of refrigerant gases that are harmful to the environment.

 

Verify the installation of connections.

 

■ Verify the supports and fixing elements (materials, routing and 

connection).

 

■ Verify the quality of welds and other joints.

 

Check the protection against mechanical damage.

 

Check the protection against heat.

 

Check the protection of moving parts.

 

Verify the accessibility for maintenance or repair and to check 

the piping.

 

Verify the status of the valves.

 

Verify the quality of the thermal insulation and of the vapour 

barriers

 

Check the condition of the insulation of the 400 V cables.
