■

Remove any potential ignition

sources

Leaking refrigerant in combina-

tion with corresponding ignition

sources can lead to an explo-

sion. All ignition sources must

therefore be kept away from

the working area at all times!

This also includes the smoking

of cigarettes. Inform all persons

present that this includes the

axing of safety notes and the

closing o of the working area.

■

Sucient ventilation

Before starting work, ensure that

the working area is outdoors

or has sucient ventilation. A

continuous ventilation stream

is required while working. The

safety of the persons working

must be guaranteed by the ex-

haust air equipment: potentially

leaking refrigerant must be lead

away safely and drained into the

atmosphere in an optimum man-

ner.

■

Checking the refrigerant circuit

If electronic components need

to be replaced, ensure that

the spare parts have the same

function and identical technical

specications. The maintenance

and replacement regulations of

the manufacturer must always

be observed and complied with.

Please contact the support of the

manufacturer with any problems

or queries. The following safety

checks must be carried out when

using combustible refrigerants:

- The ll level adjusts to the size

of the rooms in which the unit is

located.

- The exhaust air equipment and

its outlets function properly and

are not blocked or obstructed.

■

Checking the electronic compo-

nents

A component and safety check

must be carried out before

repairing and maintaining

electronic components. If safety

cannot be ensured due to a de-

fect on a component, installation

must not take place until safety

can be guaranteed again. If the

defect on the spare part cannot

be remedied and downtime of

the unit is no longer acceptable,

an adequate temporary solution

must be arranged. The owner/

operator of the unit must be in-

formed about this. The detailed

safety check must include the

following aspects:

- Capacitors are discharged. Dis-

charging must be done in a safe

process to prevent ying sparks.

- There must be no electronic

components active or uninsu-

lated wires while lling, repairing

or cleaning.

- There must be no earthing of

the system.

■

Repairs to closed components

Before repairing closed compo-

nents/housing parts, the unit

must be free from voltage. If

carrying out the repairs free from

voltage cannot be avoided, the

critical points of potential refrig-

erant leakages must be checked

using a leak detector.

The following notes must be

observed when working on elec-

tronic components if the hous-

ing is changed in such a way that

its safety is inuenced. This also

relates to cases where the lines

are damaged, there is excessive

or incorrect pin assignment, con-

nections are not assigned in the

original way or similar deviations

to the expected condition are

determined.

■

Repairing of intrinsically safe

components

Do not introduce permanent

inductive or capacitive loads

into the existing circuits without

ensuring that the maximum

permitted voltages and amper-

ages of the assemblies and lines

are not exceeded. Intrinsically

safe components are individual

components that can be operat-

ed in the presence of ammable

substances. The test equipment

must be adjusted according to

the situation-dependent condi-

tions. Only use components

which are ocially approved by

the manufacturer as spare parts.

Unapproved components can

cause a re in the event of a leak-

age in the refrigerant circuit.
