Pipes
Pipes and system components must be clean and dry inside and free of scales, metal
chippings, and coats of rust and phosphate. Only use hermetically sealed parts.
Lay pipes correctly. Avoid strong vibrations because of the risk of cracks and breaks.
Provide suitable fi xed points and/or vibration compensators as required.
Guarantee a correct oil return.
Keep pressure losses to an absolute minimum.
Laying suction and discharge line
Stable

As short as
possible
Installation
Improperly installed pipes can cause cracks and tears, which result in
refrigerant loss.
A rule of thumb:
Always lay the first pipe section starting from the compressor downward and
parallel to the drive shaft.
A proper run of the suction and discharge line immediately after the compres-
sor is of great importance for the system´s smooth running and freedom from
vibration.
Pipe connections
The
pressure and suction shutoff valves
have graduated
inside diameters, so that pipes in the customary millimeter
and inch dimensions can be used. The pipe will be
immersed more or less deeply according to dimension.
The connection diameters of the shutoff valves are designed
for the maximum compressor output.
The actually required
pipe cross-section must be adapted to the actually
refrigeration capacity. The same applies for non-return
valves.
Caution when soldering!
Remove screw connections from the valve for soldering.
Do not overheat the valve.
Cool the valve body during and after soldering.
Compressors are fi lled with protective gas ex works (approx. 3 bar nitrogen!
● Leave protective gas fi lling in the compressor up to evacuation.
● Do not open shutoff valves up to evacuation.
● Absolutely avoid entry of air!
