GENERAL INFORMATION
588/A page 5/24
On new installations, it is suggested that the valves
and piston rings be inspected after the first few
hundred hours of operation. This will give an early
indication of any abnormal problems and allow for
corrective action to be taken before a costly failure
results. Although piston ring life will vary from
application to application, wear will be fairly
consistent on subsequent sets of rings.
INSTALLATION
NOTICE:
BLACKMER COMPRESSORS MUST ONLY BE
INSTALLED IN SYSTEMS DESIGNED BY QUALIFIED
ENGINEERING PERSONNEL. SYSTEM DESIGN MUST
CONFORM WITH ALL APPLICABLE REGULATIONS
AND CODES AND PROVIDE WARNING OF ALL
SYSTEM HAZARDS.
NOTICE:
THIS COMPRESSOR SHALL BE INSTALLED IN
ACCORDANCE WITH THE REQUIREMENTS OF NFPA 58
AND ALL APPLICABLE LOCAL, STATE AND NATIONAL
REGULATIONS.
Hazardous voltage.
Can shock, burn or
cause death.
Install, ground and wire to local and
National Electrical Code requirements.
Install an all-leg disconnect switch near
the unit motor.
Disconnect and lockout electrical power
before installation or service
Electrical supply MUST match motor nameplate
specifications.
Motors equipped with thermal protection automatically
disconnect motor electrical circuit when overload exists.
Motor can start unexpectedly and without warning.
LOCATION AND PIPING
Compressor life and performance can be significantly
reduced when installed in an improperly designed
system. Before starting layout and installation of the
piping system, consider the following:
1. All piping must be leak free to a pressure of 1.5
times the maximum system pressure.
NOTICE: If the system is to be hydro-statically
tested, the compressor MUST be isolated.
Liquid entering the compressor will cause
damage and void the warranty.
2. A strainer should be installed in the inlet line to
protect the compressor from foreign matter. A #30
mesh screen or finer is recommended. Strainers
must be cleaned every 180 days, or more
frequently if the system requires.
3. Expansion joints, placed within 36" (0.9 m) of the
compressor, will compensate for expansion and
contraction of the pipes. Contact the flexible
connector/hose manufacturer for required
maintenance/care and design assistance in their
use.
4. Piping must be adequately supported to ensure
that no piping loads are placed upon the
compressor.
5. Both suction and discharge piping should slope
down from the compressor. The compressor
should not be placed at a low point in the piping
system.
Extreme Heat can
cause personal injury
or property damage
DISCHARGE PIPING SURFACE
TEMPERATURES MAY BE HOT DURING
OPERATION (OVER 158°F, 70°C).
TEMPERATURES SHOULD BE
MONITORED AND ADEQUATE
WARNINGS POSTED.
MOUNTING THE COMPRESSOR UNIT
Stationary Compressors
A solid foundation reduces
noise and vibration, and
will improve compressor
performance. On
permanent installations, it
is recommended the
compressor be secured by
anchor bolts as shown.
This arrangement allows
for slight shifting of
position to accommodate
alignment with the
mounting holes in the
base plate.
Figure 3 - Anchor Bolt
Set the anchor bolts in concrete for new foundations.
When compressors are to be located on existing
concrete floors, holes should be drilled into the concrete
to hold the anchor bolts.
To keep vibration at a minimum, in addition to a solid
concrete foundation, it is important that the concrete be
located on a stable soil foundation. The base must
have complete contact along its entire length with the
foundation. Visible separations will result in vibrations
which are magnified in the upper part of the unit.
Truck Mounted Compressors
Blackmer compressors may be mounted to the frame
rails of a truck/transport and driven by either a V-belt or
PTO drive.
The compressor should be solidly mounted and care
should be taken to ensure that the dipstick and
inspections plates are readily accessible.
Check compressor mounting bolts and baseplate
anchor bolts regularly.
