Operating Manual - SAB 202

Areas of application of screw compressor unit

Application

To prevent unintentional application of the com-

pressor, which could injure personnel or damage

the equipment, the following must be observed:

•The compressor must only be used as a re-

frigeration compressor with the number of

revolutions per minute and within the oper-

ating limits specified in the manuals or in a

written agreement with

Sabroe Refrigeration.

•The compressor must only be used with the

following refrigerants: R717, R22, R134a,

R404A, R507, R600, R600A, R290 and

LPG. Other HFC refrigerants must only be

used in accordance with

Sabroe Refrigeration's instructions. All oth-

er types of gas must only be used with a

written permission from

Sabroe Refrigeration.

•The compressors are approved for applica-

tion in potentially explosive atmospheres

provided they have been fitted with explo-

sion-proof equipment. This can be seen

from the Ex name plates fixed on each unit.

See Fig. 1.

Fig. 1

Please note that special tools which do not cause

any sparks must be used for ALL maintenance

work on the compressor.

WWarning!

Sabroe Refrigeration is not liable for injuries to

personnel or damage to equipment resulting from

using the equipment for other purposes than the

ones stated above.

Application of combustion engines

If combustion engines are installed in rooms con-

taining refrigeration machinery or rooms where

there are pipes and components containing refrig-

erant, make sure that in case of leakage the com-

bustion air for the engine comes from an area in

which there is no refrigerant gas.

Failure to do so involves a risk of lubricating oil

from the combustion engine mixing with refriger-

ant. At worst this may lead to corrosion and dam-

age of the engine.

WWarning!

The compressor must NOT be used:

•For evacuating the refrigeration plant of

air and moisture.

•For putting the refrigeration plant under

air pressure in view of a pressure test-

ing.

•As an air compressor.
