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:

 

-

Model number - size

 

-

CE marking

 

-

Serial number

 

-

Year of manufacture and pressure and leak tightness test 

date

 

-

Fluid being transported

 

-

Refrigerant used

 

-

Refrigerant charge per circuit

 

-

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

 

-

Voltage, frequency, number of phases

 

-

Maximum current drawn

 

-

Maximum power input

 

-

Unit net weight

 

■ Confirm that all accessories ordered for on-site installationhave 

been delivered, are complete and undamaged.

 

- The unit must be checked periodically, if necessary removing 

the insulation (thermal, acoustic), 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”.

2.2 - Moving and siting the unit

2.2.1 - Moving

See chapter 1.2 - “Installation safety considerations”.

2.2.2 - Siting 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 “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 do not require earthquake 

resistance. Earthquake resistance has not been verified and the 

units are not explosion-proof.

ATTENTION  :  Ne  pas  élinguer  ailleurs  que  sur  les  points 

d'ancrage prévus et signalés sur l'unité.

 

-

Before siting the unit check that:

 

-

the permitted loading at the site is adequate or that 

appropriate strenghtening measures have been taken.

 

-

if the heat pump is required to operate in temperatures below 

0°C it must be raised at least 300 mm from the ground. This 

is necessary to avoid ice build-up on the unit chassis and 

also to permit correct unit operation in locations where the 

snow level may reach this height.

 

-

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 (see dimensional 

drawings).

 

-

the number of support points is adequate and that they are 

in the right places.

 

-

the location is not subject to flooding.

 

-

Baffles may be necessary to deflect strong winds. They must  

not restrict air flow into the unit..

CAUTION: Before lifting the unit, check that all casing panels 

are securely fixed in place. Lift and set down the unit with 

great care. Tilting and jarring can damage the unit and impair 

unit operation.

If 61AF units are hoisted with rigging, it is advisable to protect coils 

against crushing while a unit is being moved. Use struts or a lifting 

beam to spread the slings above the unit. Do not tilt a unit more than 

15°.

WARNING: Never push or lever on any of the enclosure panels 

of the unit. Only the base of the unit frame is designed to 

withstand such stresses.

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.
For these checks national regulations must be followed. If the national 

regulation does not specify any details, refer to standard EN 378 as 

follows:
External visual installation checks:

 

-

Ensure that the machine is charged with refrigerant, Verify 

on the unit nameplate that the ‘fluid transported’ is R407C 

and is not nitrogen.

 

-

Compare the complete installation with the refrigeration 

system and power circuit diagrams.

 

-

Check that all components comply with the design 

specifications.

 

-

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 documents 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.

 

-

Verify the instructions and directives to prevent the deliberate 

removal of refrigerant gases.

 

-

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.

 

-

Ensure that the ventilation in the machine room is sufficient.

 

-

Check the refrigerant detectors.
