    Care must be taken when constructing total enclosures or baffle walls. If not properly constructed or positioned, they could contribute to unacceptable noise levels or over heating. Consult your local Quincy Com- pressor distributor if assis tance is required.

  • Page 13: Mounting

    Mounting Proper mounting of Quincy compressor units is crucial to the safe operation and longevity of the equipment. The installation requires a flat and level concrete floor or pad (for mobile units see Mounting Mobile Units). Satis- factory results can usually be obtained by mounting horizontal tank units on vibration isolators available from your local Quincy distributor.

    If, however, the compressor is to be installed in a location where consid- erable dust, dirt and other contaminants are prevalent, consult your local Quincy distributor for advice and optional filters. A condensate trap must be installed as close as possible to the inlet filter if, as a result of installation or environmental conditions, there is any risk of moisture forming in the inlet piping.

  • Page 23 Quincy Compressor recommends that a new or rebuilt reciprocating compressor should be run for a total of 100 hours at full discharge operating pressure to break­in the new piston rings. Until the rings are seated, the compressor will discharge higher than normal amounts of lubricant. In light of this fact, the lubricant level should be checked more frequently during the 100 hour break­in period.

  • Page 24: Maintenance & Lubrication

    Check the lubricant level several minutes after the compressor has run. (Discoloration or a higher lubricant level reading may indicate the presence of condensed liquids.) If lubricant is contaminated, drain and replace. QR-25 Series Quincy Compressor 52201-107, January 2014 3501 Wismann Lane, Quincy IL - 62305-3116...
