!CAUTION:
NEMA electrical enclosures and components
must be appropriate to the area installed.
Pneumatic Circuit Breakers or Velocity
Fuses
The Occupational Safety & 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 inch 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 be in compliance with OSHA Safety and Health
Standards 29 CFR 1910.219 and any state or local
codes.
Manual Relief and Shutoff Valves
Install a manual relief valve to vent the compressor and
the compressor discharge line to atmosphere. In those
instances where the air receiver tank services a single
compressor, the manual relief valve can be installed in
the receiver. Where a manual shut-off valve (block
valve) is used, a manual relief valve should be installed
upstream from this vaIve, and a safety relief valve
installed upstream from the manual relief valve. These
valves are to be designed and installed to permit
maintenance to be performed in a safe manner. Never
substitute a check valve for a manual shut-off valve
(block valve) if the purpose is to isolate the compressor
unit from a system for servicing.
!WA~~G!
Relieve compressor and system air pressure by
opening the appropriate manual relief valve prior
to servicing. Failure to relieve all system pressure
may result in severe personal injury, death and
property damage.

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.
NOTE: The water temperature regulating valve is
located in the discharge water line.
Safetv LabeIs/Decals
!wARN~G!
Removal or painting over safety labels will result
in uninformed conditions. This may result in
personal injury, death or property damage.
Warning signs and labels shall be provided with
enough light to read, conspicuously located and
maintained for legibility. Do not remove any
warning, caution, or instructional material
attached.
Instruction Manual
!CAUTION!
Iprovisions should be made to have the instmction
manual readily available to the operator and
I maintenance personnel. If for any reason, any
parts of the manual become illegible, or if the
manual is lost, have it replaced immediately. The
instruction manual should be periodically read to
refresh one’s memory, it may prevent a serious
accident.
Drive Coupling AliWment
QMA units are direct coupled between the airend and
the drive motor through the use of a transition piece.
Realignment of the coupling is not necessary.
