CAUTION
Excessive noise can be effectively reduced through various methods. Total
enclosures, intake silencers, baffle walls, relocating or isolating the compressor
can reduce noise levels. 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 overheating. Consult your local Quincy
Compressor Distributor if assistance is required.
Unusual noise or vibration indicates a problem. Do not operate the
compressor until the source has been identified and corrected.
%pply Requirements
The electrical installation of this unit should be performed by a qualified
electrician with knowledge of the National Electrical Code (N, E.C.), O. S.H.A.
code andlor any local or state codes having precedence.
Before installation, the electrical supply should be checked for adequate
wire size and transformer capacity. A suitable circuit breaker or fused
disconnect switch should be provided. When a 3 phase motor is used to drive
a compressor, any unreasonable voltage imbalance between the legs must be
eliminated and any low voltage corrected to prevent excessive current draw.
Note: This unit must be grounded.
The installation, electric motor, wiring, and all electrical controls must be
in accordance with NFPA 70-1993 National Electric Code, National Electric
Safety Code, state and local codes. Failure to abide by the national, state and
local codes may result in physical harm and/or property damage.
High voltage may cause personal injury or death. Disconnect and
Iockoutitagout per O. S.HA. regulation 1910.147 all electrical power
supplies before opening the electrical enclosure or servicing.
Never assume a compressor is safe to work on just because it is not
operating. It could restart at any time. Follow all safety precau-
tions outlined in SECTION 5, Stopping For Maintenance.
NEMA electrical enclosures and components must be appropriate
to the area installed.
Mounting
Proper mounting of Quincy compressors is crucial to the safe operation and
longevity of the equipment. The installation requires a flat and level concrete
floor or pad. Satisfactory results can usually be obtained by mounting the
compressor on vibration isolating pads available from your local Quincy
Distributor.
State or local codes may mandate that the compressor be bolted to the floor.
In this case the unit must be leveled and bolted making absolutely certain the
feet are not stressed in any manner. Uneven feet drawn tightly to the concrete
pad will cause severe vibrations resulting in cracked welds or fatigue failure.
