Section III – Installation
Pressure Vessels
Air receiver tanks should be in accordance with ASME Boiler and Pressure Vessel Code Section VIII.
! WARNING !
ASME coded pressure vessels must not be modified, welded, repaired,
reworked or subjected to operating conditions outside the nameplate
ratings. Such actions will negate code status, affect insurance status and
will cause death.
Electrical
Before installation, the electrical supply should be checked for adequate wire size and capacity. During
installation, a suitable fused disconnect switch or circuit breaker should be provided. Where a 3-phase
motor is used to drive a compressor, any unreasonable voltage unbalance (5%) between the legs must
be eliminated and any low voltage corrected to prevent excessive current draw. The installation, electric
motor, wiring and all electrical controls must be in accordance with National Electric Code, and all state
and local codes. A qualified electrician should perform all electrical work.
This unit must be grounded
in accordance with applicable codes.
See control panel for the proper wiring diagram.
Quincy would like to emphasize the importance of providing adequate grounding for air compressors.
The common practice of grounding units to building structure steel may not actually provide adequate
grounding protection, as paint and corrosion build-up may exist.
! CAUTION !
NEMA electrical enclosures and components must be appropriate to the
area in which they are installed.
Pneumatic Circuit Breakers or Velocity Fuses
The Occupational Safety and Health Act, Section 1926.303 Paragraph 7 published in Code of Federal
Regulations 29 CFR 1920.1 revised July 1, 1982, states "all hoses exceeding 1/2" inside diameter shall
have a safety device at the source of supply or branch line to reduce pressure in case of a hose failure."
These pneumatic safety devices are designed to prevent hoses from whipping, which could result in a
serious or fatal accident.
Guards
All mechanical action or motion is hazardous in varying degrees and needs to be guarded. Guarding
shall comply with OSHA Safety and Health Standards 29 CFR 1910.219 in OSHA manual 2206 Revised
November 7, 1978 and any state or local codes.
