Section III - Installation

Electrical

Pneumatic Circuit Breakers or Velocity Fuses

Before installation, the electrical supply should be checked for adequate wire size and branch circuit capacity. During installation, a suitable fused disconnect switch or circuit breaker should be provided per local electrical codes. Where a 3-phase motor is used to drive the compressor, any unreasonable voltage unbalance (5%) between the legs must be eliminated and any low voltage corrected to prevent excessive current draw. The installation and wiring must be in accordance with National Electric Code and all state and local codes. A qualified electrician must perform all electrical work.

This unit must be grounded in accordance with

applicable codes. See control panel for the proper wiring diagram.

NOTE

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, conduit, motor enclosures and components must be appropriate to the area in which they are installed.

The Occupational Safety and Health Act, Section 1926.303, Paragraph 7, published in the 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.” The 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 be in compliance with OSHA Safety and Health Standards 29 CFR 1910.219 in OSHA manual 2206 Revised November 7, 1978 and any state or local codes.

Water and Sewer Facilities at the Installation Site (Water-cooled models only)

Make sure the water supply is connected and open. Piping supplied by the user should be at least equal to the connections provided on the compressor. Sewer facilities should be readily accessible to the installation site and meet all the requirements of local sewer codes, plus those of the compressor. Make absolutely sure water inlet

and discharge connections are correct.
