!CAUTION!
Removal or modification of sound insulation will
result in higher sound levels which may be
hazardous to
personneI.
The Quincy QMA models are essentially vibration free,
however some customers may choose to bolt the unit to
the floor to prevent the accidental breakage of piping or
electrical connections, if bumped. Use lag bolts to
position the unit only. Do not pull the bolts down tight
since this, under some circumstances, may place the
frame in a twist or bind causing eventual breakage of
fluid coolers, piping, receiver tanks, etc.
!WARNJNG!
Under no circumstances should a compressor be
installed in an area that may be exposed to a
toxic, volatile or corrosive atmosphere, nor should
toxic, volatile or corrosive agents be stored near
the compressor. Severe personal injury, death or
property damage may result.
Piping Connections
Never join pipes or fittings by soldering. Lead-tin
solders have low strength, a low creep limit and
depending on the alloy start melting at 360 degrees F.
Silver soldering and hard soldering are forms of
brazing and should not be confhsed with lead-tin
soldering. Silver soldering and hard soldering are
brazing with silver-alloy types of filler material and
melt in the range of 1145 degrees F to 1800 degrees F.
Never use plastic, PVC or ABS pipe in a compressed
air system.
Care must be taken to avoid assembling the piping in a
manner that strains the compressor. Piping should line
up without having to be sprung or twisted into position.
Adequate expansion loops or bends should be instrdled
to prevent undue stresses at the compressor resulting
from the changes between hot and cold conditions.
Pipe supports should be mounted independently of the
compressor and anchored as neces.say to limit vibration
and prevent expansion strains. In no case should the
piping be of smaller size than the connection on the
compressor unit,
Pressure Relief Valves
!J)AN~ER!
Pressure relief valves are to protect system
integrity in accordance with ANWASME B19
safety standards. Failure to provide properly
sized pressure relief valves will cause severe
personal injury or death.
Pressure Relief valves are sized to protect the system.
Never change the pressure setting or tamper with the
valve. Only the pressure relief valve manufacturer or
an approved representative is qualified to make such a
change.
Pressure relief valves are to be placed ahead of any
potential blockage point which includes, but is not
limited to, such components as shutoff valves, heat
exchangers and discharge silencers. Ideally, the
pressur; relief valve sh&dd be threaded directly into the
pressure point it is sensing, not connected with tubing
or pipe. Always direct discharge from pressure relief
valves to a safe area away from personnel.
!WARN~G!
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 may cause
severe personal injury, death and property
damage.
Electrical
Before installatio~ the electrical supply should be
checked for adequate wire size and transformer
capacity. During installation a suitable fised or circuit
breaker disconnect switch should be provided. Where a
3 phase motor is used to drive a compressor, any
unreasonable voltage unbalance
(5°/0)
between the legs
must be elimimted and any low voMage corrected to
prevent excessive current draw. The installation,
electric motor, wiring and all electrical controls must be
in accordance with NFPA 70, National Electric Code,
State and local codes. AH electrical work should be
performed by a qualitied electrician. This unit must be
grounded in accordance with applicable electrical
—
codes. See control panel door for the proper wiring
diagram.
