7. Cautions for parallel piping

8. Cautions for parallel piping

Completely, close the stop valve of the discharge

valve at the compressor that is manually stopped
during the operation. 

If opening the stop valve of the suspended

compressor, the backward pressure is allowed to
After Cooler at the compressor, generating a
drain, probably causing rust inside the cooler and
check valve and subsequently, reducing the life of
the compressor. 

Operating

Stopping

Stop valve opened

Stop valve closed

Stop valve

Stop valve

Apply shock-absorbing materials to the reciprocating compressor so that the
vibration of reciprocating compressor is not conveyed to the screw compressor,
probably generating air leakage.
